The forecast for the May 2026 US Gulf NOLA Urea Granular Spot Price is driven by a massive structural break in global supply chains following the closure of the Strait of Hormuz on February 28, 2026. This region accounts for roughly 31% to 40% of global urea exports, and its disruption triggered a vertical price movement in March and April. While the IMF Primary Commodity Price System (PCPS) series recorded a value of 263.02 USD/ST in February and 378.04 USD/ST in March, these monthly averages significantly lag the high-frequency market data. By late March, spot loads in New Orleans were already trading above $645/ST. April 2026 futures and CFD data show the market averaged approximately $697/ST for that month, with peaks as high as $780/ST in mid-April.
My analysis centers on a most likely value of 598.75 USD/ST, which represents a cooling from the April peak but a sustained high-price regime. Several factors support this ‘elevated normalization’ scenario. First, the Strait of Hormuz was reported to have reopened around April 17, 2026, and the World Bank’s baseline assumes acute disruptions will end in May. This is corroborated by the market’s state of backwardation, where June 2026 futures are trading lower (near $585/ST) than May contracts (roughly $631/ST). This downward slope suggests that while the immediate panic has subsided, supply remains physically tight.
Second, domestic factors in the US reinforce this high floor. The spring planting season is the period of peak demand, with 2026 corn acreage estimated at a robust 93 to 95 million acres. On the supply side, a major domestic producer (CF Industries) has its Yazoo City facility offline until at least Q4 2026, and global channel inventories are reported to be below historical averages. China’s continued restriction on urea exports further limits the potential for a rapid price collapse.
The weight of evidence suggests that the IMF May average will capture the transition from the April panic highs toward the late-May expected normalization. A value near $600/ST aligns with late-April futures settlements and the expected cooling of the spot market after the reopening of major shipping routes. Higher values (above $700) are possible if logistics normalization is slower than expected, while a return to pre-shock levels (sub-$400) is highly unlikely given the seasonal demand and current inventory deficits.
Question: what will the IMF monthly-average US Gulf (NOLA) granular urea spot price be for May 2026? Forecasters agree the contract resolves to the IMF’s May monthly average — so what matters is where the NOLA market spends the whole month, not a single late‑April spike. All teams anchor on live NOLA cash/futures (late‑April physicals $680–760/st; May futures ≈ $630–657, June ≈ $585), and on a persistent global supply shock (Qatar/Iran outages plus China/Russia export limits) that keeps import‑parity costs elevated; U.S. domestic conditions and gas provide only partial offsets. The consensus central case is a May average in the low–to–mid $600s (modal probability mass ~40–65%), with a meaningful upper tail (~15–20%) that the monthly mean stays ≥ $700 if tightness persists, and a smaller chance (~8–25%) of a moderate pullback into the $500s if supply eases quickly. Forecasters also caution that historical analogues show rapid mean reversion is possible once concrete supply relief arrives, and that final judgment should be updated when the official IMF March/April prints and May cash trade data are fully verified.
Forecast: Probability distribution:
We are forecasting the IMF PCPS monthly average for “US Gulf NOLA Urea Granular Spot Price, USD/ST” for May 2026. As of 2026-05-03, the month is in progress, so the outcome will be the average over the full month as later published by the IMF.
Across analysts, three (Forecasters 1–3) converge on a very high regime in spring 2026, citing contemporaneous market indicators: early-April NOLA indications around 679–700 USD/ST (Forecaster 3, with a specific PDF citation) and early-May futures/quotes around ~631–640 (Forecasters 1 and 3). Forecaster 2 also uses IMF-history claims that suggest a sharp rise already underway by March 2026 (into the high 300s) and expects continued elevation into May, but with more mean reversion (median ~530). Forecaster 4 is a major outlier (median ~369) based on an inferred “IMF is ~0.56–0.60 of benchmark” scaling; that scaling is not well-supported given the series definition (it is explicitly a spot price in USD/ST), and is plausibly explained by unit/benchmark mismatches (metric-ton vs short-ton, retail/delivered vs FOB barge, etc.). I therefore treat Forecaster 4 primarily as a low-price scenario rather than the central case.
Synthesis: the best point anchor is the contemporaneous May futures/quotes near ~630 USD/ST, with expectation of some easing from early-April highs but not a full collapse. Because the monthly average can move substantially if prices normalize quickly (we are only 3 days into May), I keep a meaningful left tail. I also keep a non-trivial right tail above the 700 open bound (sustained disruption/tightness), but not as dominant as Forecaster 1/2, since exceeding 700 on a monthly average typically requires many days well above 700.
This yields a median around 612 USD/ST, with roughly ~5–7% chance the IMF value ends up below the 250 lower bound, and roughly ~10–15% chance it ends up above 700.
An amateur forecast would likely anchor on the provided May 2025 value (266.70) or on the middle of the [250, 700] bounds without integrating current in-month information, and would likely fail to represent out-of-range probability despite open bounds. My forecast explicitly conditions on the analysts’ cited contemporaneous 2026 market signals (spot/futures levels near ~630 and reports of ~680–700 in early April), while still allowing for rapid normalization (wide left tail) and for sustained tightness (right tail expressed properly with percentiles >700). Confidence in improvement is moderate: it mainly comes from anchoring to current-price evidence while correcting for a likely unit/benchmark confusion in the low outlier.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the core view is that the US Gulf urea spot price for May 2026 should be materially higher than the winter IMF-linked levels, likely landing in the low-to-mid $500s per short ton on average.
Overall, the forecasts converge on a view of sharp spring inflation in urea prices, with May 2026 likely averaging in the low-to-mid $500s/ST but with wide tails around that center.
— Iteration 2 — The forecasts share a common approach: they start from the last confirmed IMF urea price in February 2026 and then adjust using more recent market indicators, especially non-IMF spot benchmarks and futures, to estimate where May 2026 should land.
The collective view is that the IMF May 2026 US Gulf urea spot price should reflect a market that has sharply strengthened from early-year levels, but with uncertainty over whether the recent spike will persist. The core debate is between a partial normalization scenario and a still-elevated market scenario, with both allowing for wide tails due to urea’s historically volatile pricing.
Market Baseline and IMF Methodology Forecasters base their projections on the IMF’s calculation method, which uses a simple arithmetic average of weekly physical spot price assessments throughout the month. To anticipate this average, forecasters heavily rely on front-month futures contracts (specifically CME NOLA Urea futures) as the primary, market-implied anchor, since these contracts cash-settle directly against the same physical spot assessments.
Upward Pressures: Geopolitical Supply Shocks Global urea markets are currently defined by a massive risk premium and supply bottlenecks. The primary driver of elevated prices is the blockade of the Strait of Hormuz, which has stranded a massive volume of Middle Eastern exports. This supply vacuum is compounded by structural export bans and quotas from China and Russia. Furthermore, high international benchmark prices and robust global tenders create a “reverse arbitrage” risk; because US Gulf prices have occasionally traded at a discount to global markets, an increase in export demand could drain domestic supply and force local prices to spike higher.
Downward Pressures: Seasonality and Demand Destruction Despite global supply shocks, strong localized bearish factors are driving market backwardation, indicating an expectation that prices will cool over the summer. Domestically, May marks the transition out of the peak US spring application season, leading to a historical mid-year slump in demand. This seasonal cooling is being accelerated by significant demand destruction: astronomically high fertilizer costs relative to lower corn prices have forced farmers to slash application rates or shift acreage to less nitrogen-intensive soybeans. Additionally, highly discounted domestic natural gas has allowed US producers to maximize output, which has temporarily flooded the domestic market and created logistical gluts at regional transit hubs.
Summary Ultimately, the May urea spot price will be defined by a tug-of-war between conflicting global and local forces. The overarching price floor is rigidly supported by severe global supply chain paralysis and geopolitical risk, while immediate domestic trends point downward due to seasonal application wrap-ups, demand destruction, and strong localized production.

The research outlines the current state and projected trajectory of the US Gulf NOLA urea granular spot price for May 2026, influenced by significant geopolitical events, particularly the military strikes on Iran and the subsequent blockade of the Strait of Hormuz. This blockade has severely impacted global urea trade, causing a drastic reduction in Gulf-region fertilizer exports. The analysis includes various price data points from the IMF, Bloomberg, and CME, highlighting a notable spike in prices due to the conflict, followed by a decline as the market adjusts to the situation. The futures market indicates a backwardated curve, suggesting expectations of declining prices as supply disruptions ease.
Forecasts from the World Bank and Trading Economics project a range of prices for May 2026, with estimates suggesting a central average between $560 and $620 per short ton. The research emphasizes the uncertainty surrounding the geopolitical landscape, potential recovery of supply chains, and seasonal demand factors that could influence price movements. Overall, the findings indicate a market in transition, with prices expected to remain elevated compared to pre-crisis levels but on a downward trend from recent peaks.
Sources used in the research include:
The urea market has been dramatically disrupted by a major geopolitical event: US and Israeli military strikes on Iran beginning February 28, 2026, which prompted Iran to blockade the Strait of Hormuz [1][2][9]. This waterway handles approximately 46% of global seaborne urea trade and the Middle East accounts for 40–43% of global marine urea exports [2][5]. Gulf-region fertilizer exports plummeted from ~1.7 million tons/month to ~300,000 tons in March 2026 [5]. A ceasefire was announced on April 8, 2026, but subsequent negotiations in Islamabad concluded without results, and the US has initiated a blockade of Iranian ports [9][10].

Recent Spot & Futures Prices (USD/Short Ton):
Futures Curve (CME, as of May 1, 2026): [16][17]
This backwardated curve implies the market expects prices to continue declining as supply disruptions ease.
World Bank (April 2026 Commodity Markets Outlook): Global urea prices projected to surge ~60% year-on-year in 2026, averaging ~$675/metric ton (~$612/short ton). Under adverse conditions, prices could exceed $700/MT (~$635/ST). Prices expected to decline ~25% in 2027 as Middle East exports recover [20][21][22][23][24][29].
Trading Economics models: Urea forecast at $597.92/ST by end of Q2 2026 and $667.95/ST within 12 months [15].
World Bank baseline assumption: The most critical phase of supply disruptions ends by May 2026, with maritime transport through the Strait of Hormuz gradually recovering and stabilizing near pre-war levels by Q4 2026 [24][27].
The IMF PCPS publishes monthly average spot prices (averaged from weekly/daily assessments within the month). Key considerations:
If prices in May average somewhere around the $550–$630/ST range, accounting for continued gradual decline from the May 1 levels (~$585–631), a central estimate of roughly $560–$620/ST for the May 2026 IMF monthly average seems plausible.
| Period | Context | Urea Price (USD/ST, US Gulf NOLA) |
|---|---|---|
| April 2022 | Post-Ukraine invasion peak | ~$1,050 (all-time high) |
| 2022 average | Ukraine conflict year | ~$600–700 range |
| H2 2023 | Post-crisis normalization | ~$300–400 |
| 2024 average | Stable period | ~$250–350 |
| 2025 average | Relatively calm | ~$180–267 |
| Pre-crisis early 2026 | Jan–Feb 2026 | ~$232–263 |
| Crisis peak | Mid-April 2026 | ~$720–737 |
Key historical analogy: The 2022 Ukraine/Russia crisis saw urea prices surge to ~$1,050/ST before gradually declining. The current Hormuz crisis has pushed prices to a lower peak (~$737) but the disruption to seaborne fertilizer trade is arguably more severe (46% of seaborne urea vs. ~15% for Russia/Ukraine routes). However, the ceasefire and market expectations of Hormuz reopening are pulling prices down faster.
Typical post-crisis price behavior: After the 2022 peak, it took approximately 6–9 months for prices to return to pre-crisis levels. The current futures curve suggests a similar pattern, with a ~$90 decline expected from May to September 2026.
No dedicated prediction markets for urea prices were found. The closest proxy instruments are:
Downside risks (lower prices):
Upside risks (higher prices):
The May 2026 IMF monthly average for US Gulf NOLA urea granular spot price will likely reflect a market in transition — still dramatically elevated from pre-crisis levels (~$233–267/ST) but declining from the mid-April peak (~$720–737/ST). Multiple data points converge on a likely range of $550–$650/ST, with the CME futures ($631), Trading Economics forecast (~$598), World Bank annual average projection (~$612/ST equivalent), and the declining spot price trajectory all pointing to this zone. The most likely outcome appears to be roughly $570–$620/ST, assuming the downward trend from late April continues moderately through May.
The critic raises several compelling points that I need to address:
Thin futures liquidity: The critic is correct that 205 contracts (~20,500 ST) is extremely thin liquidity. I over-weighted this signal. The 14.23% single-day spot price decline is a much stronger signal of market direction than the futures price.
Inconsistency between trend and median: This is the most valid criticism. I stated prices are declining and the futures curve is backwardated, yet I set my median at $598—above the current spot price of $585. This is logically inconsistent. If we expect continued decline, the monthly average should be lower than the starting point.
Monthly average mechanics: The arithmetic for a declining trend month is straightforward: if May starts at ~$600 and ends at ~$560, the average would be ~$580. My original median was too high.
However, I maintain that:
Geopolitical tail risk remains significant: The failed Islamabad negotiations and US port blockade of Iran create real escalation potential. The right tail should remain substantial.
14% daily moves cut both ways: While the May 1 drop signals momentum, such extreme volatility could reverse on any diplomatic development or escalation news.
IMF methodology smoothing: The March 2026 IMF average of $378 reflects a partial-month ramp-up. This doesn’t directly inform May’s dynamics but confirms monthly averages capture mid-month values heavily.
Recalculating the monthly average trajectory:
The futures curve (June $585 → September $545) implies approximately $8-10/month decline. This supports a May average around $580-590.
I’m adjusting my median down from $598 to $588, accepting the critic’s point about trend consistency. I’m also fattening the left tail slightly to account for rapid resolution scenarios, while maintaining the right tail for escalation risk.
The key adjustment: I was anchoring too heavily on the $631 futures price rather than the $585 spot and the clear downward trajectory. The spot market with its 14% drop is telling us more about real-time price discovery than the illiquid futures market.

The Round 5 critic makes compelling final points that warrant adjustment:
Lower Tail Mathematical Constraints: The critic correctly identifies that P10 at $572 requiring remaining days to average ~$569—$16 below June futures ($585) during active conflict—is too generous. Similarly, P5 at $548 requiring ~$536 for remaining days is overly optimistic given the ongoing US port blockade.
The “Floor” Question: The backwardated curve bottoms at $545 in September—4 months away. Prices falling to near that level in May during active economic warfare between US and Iran seems implausible without extraordinary breakthrough.
India Physical Market Signal: Even after $80-100/ST freight adjustment, implied physical price is ~$750/ST. The gap between this and my P50 ($640) suggests I may still be underweighting physical market tightness by ~$5-10.
US Port Blockade Underweighted: This is the most important point. The blockade represents new escalation after the ceasefire. Markets priced in the ceasefire optimism but may not have fully adjusted for subsequent US aggression and potential Iranian retaliation.
Documented Price Decline Is Real: Prices fell from $720-737 mid-April to $585-631 by May 1. This isn’t speculation—it’s recorded market movement.
CME Futures Still Informative: Despite thin liquidity, $631 represents actual market expectations and deserves weight in the central estimate.
The critic’s framing of “why would May average below June futures during active conflict” is particularly clarifying. If June is expected at $585 and the US-Iran blockade war continues through May, there’s no logical reason for May to average below June’s expected level.
I’m accepting most of the critic’s final suggestions:
The distribution now properly reflects the binding mathematical constraints from early-May data combined with the reality that prices falling below June futures during active conflict represents an especially low-probability outcome.

The critic continues to make well-reasoned points that warrant final adjustments. Let me address them systematically.
Lower tail inconsistency: The critic correctly identifies a logical tension in my forecast. I acknowledge “new US blockade” and “failed negotiations” as escalatory signals, yet still assign ~20% probability to prices below $560. This is indeed inconsistent—what’s the catalyst for such rapid de-escalation during an actively intensifying crisis?
Median marginally conservative: The $607 median sits at the lower end of converging forecasts:
A balanced weighting favors something closer to $610-612.
Not going to $614 median: While I’ll raise my median, I don’t want to overcorrect. The Trading Economics spot ($585) and forecast ($598) anchor the lower end, and I maintain some probability that prices continue their recent decline if tensions stabilize.
Upper tail structure: I believe my escalation tail (P90-P99.9) remains appropriately calibrated. We haven’t approached 2022 levels despite severe trade disruption, suggesting some market resilience.
Crisis phase identification: We’re in the “uncertainty/volatility” phase—neither resolution nor catastrophic escalation has crystallized. This argues for compressing extreme tails while maintaining meaningful probability in the $570-660 core range.
Physical market floor confirmation: India’s $850-870/ST tender confirms genuine physical tightness. Even with US Gulf spot trading below these levels, this establishes a fundamental floor that makes rapid price collapse unlikely.
I’m accepting the critic’s core recommendations:
The question creator’s bounds (250-700 as likely range) align well with my distribution, with appropriate tail probability outside this range for extreme scenarios.

Internal inconsistency: The critic is absolutely right that I stated trend analysis suggests $550-580/ST, yet my median was $595. This ~$20 gap is unjustified and I should resolve it by lowering my median.
Thin futures liquidity: I acknowledged the CME contracts had only 205 open interest, yet still heavily weighted the $631 price. I should be more skeptical of this signal while still incorporating it.
Backwardated curve signal: The May→June→July futures curve ($631→$585→$565) is a strong directional signal that I didn’t fully incorporate into my median estimate.
Monthly averaging effect: The critic actually validates this - their own “hot take” notes that averaging inherently dampens volatility. A price path swinging between $550-$700 could still average to ~$575-600.
Ceasefire significance: While Islamabad talks failed and the US is now blockading Iranian ports, the market has clearly priced in de-escalation expectations. The 14% single-day drop on May 1 shows real money voting for lower prices.
Early May prices create a floor: With the question opening May 3 at prices around $585-631, the first ~3 days are essentially locked in at elevated levels. This provides downside protection for the monthly average.
India procurement as a signal: The critic’s point about India paying $935-959/MT CFR (while spot is $585/ST) deserves more weight. Either India is overpaying dramatically, or physical availability at quoted spot prices is illusory. This should inflate my upside tail.
Sequential dynamics: Ceasefire → failed talks → US port blockade looks like escalation masking as de-escalation. However, the market seems to be discounting the new blockade, suggesting it’s viewed as negotiating pressure rather than genuine escalation.
If prices entered May at ~$600-630 and decline linearly to ~$545-570 by month-end (following the futures curve), the monthly average would be approximately $570-590. This aligns with the critic’s suggested median of $578 rather than my original $595.
I’m lowering my median to ~$578, slightly widening the downside (accepting the de-escalation scenarios), and maintaining the upside tails given the India signal and ongoing tensions.

1. Physical-Paper Spread (Valid) The critic correctly identifies that my median remains closer to paper market signals despite acknowledging that IMF tracks actual transactions. The India tender ($850-870/ST CFR, implying ~$750-800/ST FOB adjusted) represents $2+ billion of actual purchasing versus ~$13M in thin CME futures. If I truly believe IMF methodology favors physical transactions, my median should reflect this more strongly.
2. World Bank Arithmetic (Compelling) The math remains inescapable: Q1 at ~$291/ST + annual projection ~$612/ST = Q2-Q4 must average ~$720+/ST. The backwardated curve to $545 is mathematically incompatible. Either:
This supports a higher May estimate than pure futures-based reasoning suggests.
3. Lower Tail Firmness (Agree) Physical constraints create a genuine floor: documented scarcity (India tender), price-inelastic spring planting demand, logistics delays from Cape rerouting, ongoing US-Iran tensions. A 5th percentile closer to $505 is more defensible.
Declining Trend Remains Valid The ~20% peak-to-current decline is unmistakable. Post-ceasefire market psychology shifted meaningfully. I won’t completely abandon this signal, even if the pace slows.
After five rounds, the critic and I have converged to a distribution differing by only ~$3-5 across percentiles. The remaining disagreement centers on exactly how much weight to give physical vs. paper market signals.
My final adjustment:

Reviewer Panel:
Reviewer (reasoning)
The draft’s weakest link is its heavy reliance on a single CME futures snapshot ($646/ST) to predict the IMF’s PCPS monthly average, without demonstrating that historical NOLA monthly averages actually track front-month futures. It also downplays the near-15% month-on-month drop in the global urea benchmark and the potential for partial reopening of the Strait of Hormuz to drive spot prices lower. Finally, it omits consideration of seasonal planting-cycle demand patterns and inventory dynamics that could materially alter May averages.
Objections:
Reviewer (calibration)
The draft forecast heavily relies on futures prices and early-month physical market peaks, potentially underestimating the impact of the rapid downward trend observed in the global urea benchmark and signals of de-escalation at the beginning of May. It also doesn’t fully account for the potential lag and smoothing effect of the IMF’s monthly average reporting compared to immediate spot prices or futures, which could lead to a lower reported value. The forecast’s reasoning, while acknowledging a downward trend, still anchors too strongly to the higher futures price and an potentially overstated level of ongoing supply disruption.

Adjustment Rationale:
Adjusted toward lower bins in response to two valid reviewer points: (1) IMF PCPS publishes a monthly average, which will smooth over peak prices if May trends down from its current ~$646/ST start as the Trading Economics global benchmark already shows (-14.23% on May 1, -14.91% MoM); (2) the ‘Strait 95% closed’ framing in my draft overstates current disruption given the April 8 ceasefire and the May 3 Iranian tanker crossing, which compresses the upper-tail risk. I also corrected a factual conflation: the May 1 urea benchmark drop was not caused by May 3 Iranian negotiations (those moved crude oil). Modal bin shifts from 600-700 (29%) to 550-600 (23%), with mass redistributed: 500-550 rises from 13% to 19%, while Above 700 falls from 16% to 10% and 600-700 from 29% to 22%. P(>$550) drops from 0.66 to 0.55, closer to the 45.7% ensemble signal but still reflecting the genuine CME futures anchor at $646/ST and physical barge market evidence above $600 throughout March-April 2026.

Model’s Answer: Looking at this carefully, I need to reconcile a few things:
Historical IMF PCPS Data (USD/ST):
Current Market Data (May 3, 2026):
Key Analysis:
A massive price surge evidently occurred between February 2026 (last IMF data at 263) and April-May 2026, driven by supply tightness. Multiple sources independently confirm prices in the 580-700 range. The CME May futures contract (640 USD/ST) is the best single predictor of the monthly average, as it settles to approximately the monthly average of spot assessments.
However, there are strong signals prices may be declining from April peaks: May 1 saw a 14% daily drop in spot; June futures show further decline to 595. The monthly average will reflect the full trajectory through May 31.
Critical Assumptions:
Low outcome scenario (~10%): Prices collapse from April highs as supply normalizes rapidly, bringing the monthly average toward 350-450. This would require a sustained ~30%+ decline through May.
High outcome scenario (~10%): Supply crisis deepens, prices stay at or above April levels, pushing monthly average above 720. Possible if supply disruptions worsen.
Given the convergent evidence of a massive price surge but also signs of early-May correction, I center my distribution around 570-600, with wide tails reflecting extreme recent volatility.

I forecast the IMF May 2026 US Gulf NOLA urea price at about $635 per short ton, with about 20% probability that the final IMF value is above $700/ST.
The resolution source is narrow. It is the IMF Primary Commodity Price System monthly period average for the U.S. Gulf NOLA granular urea spot price, in nominal current U.S. dollars per short ton. The IMF says its commodity prices are period averages, not seasonally adjusted, and monthly data are normally updated in the first full week after the reference month; recent observations can also be revised when source data are replaced or updated (IMF FAQ). The IMF specification table identifies the nitrogen/urea item as the US Gulf NOLA Urea Granular Spot Price, USD/ST, with USDA/DataStream as the source and weekly quotations as the input frequency (IMF Table 3).
The May 2026 month has just started. The stale official monthly series is much lower than the live market. The best direct public market anchor I found is the May 2026 Urea U.S. Gulf CBOT front contract at $631/ST, with futures data provided by DTN, CME Group, and ICE (Farmbucks fertilizer futures, crawled May 2026). I treat that as the strongest point estimate, but not as a precise forecast, because the contract is thin and the physical shock is still unfolding.
The historical backbone is a full IMF monthly series from January 2003 through March 2026, 279 monthly observations, nominal USD per short ton. In that history the mean is about $250/ST, the median about $225/ST, the minimum about $118/ST, and the maximum about $663/ST; the March 2026 value was $378.04/ST, up 43.7% from February 2026’s $263.02/ST, which makes the current move a shock-regime observation rather than ordinary seasonality (IMF Excel database, Cbonds IMF subgroup mirror). The annual official IMF table also shows the useful analogue: the nitrogen/urea series averaged $331.4/ST in 2021, $542.5/ST in 2022, and $275.6/ST in 2023, so the 2022 energy-war shock is a better reference class than the calm 2024-2025 period (IMF Table 3).
The current physical market is far above the March IMF print. A U.S. fertilizer market update dated April 6 put Urea US Gulf NOLA at $679-$700/ST on April 3, compared with $670-$705/ST the prior week and $380-$420/ST a year earlier; it also said NOLA barge trades had reached $679-$700/ST FOB (ATS fertilizer update, April 6, 2026). That says the March IMF monthly average had not yet absorbed the full April shock.
The futures market then pulled the May average estimate down. The May 2026 Urea U.S. Gulf CBOT front contract was shown at $631/ST at the start of May (Farmbucks fertilizer futures, crawled May 2026). CME’s smaller Urea U.S. Gulf contract is cash-settled to the arithmetic average of ICIS and Profercy midpoint assessments during the contract month, so it is economically close to the same assessment family as the IMF NOLA urea series, even though it is not the resolution source (CME Urea U.S. Gulf FAQ). This is why I center the distribution near the low $600s rather than near the April spot high.
The supply backdrop keeps the upper tail large. The World Bank’s April 28, 2026 Commodity Markets Outlook says fertilizer prices are projected to rise 31% in 2026, driven by a 60% jump in urea prices, and that its baseline assumes the most acute Strait of Hormuz disruptions end in May and shipping gradually returns to pre-war levels by late 2026 (World Bank press release, April 28, 2026). S&P Global reported on April 17 that fertilizer market participants reacted cautiously to Iran’s announcement that the Strait was completely open, because the ceasefire was time-limited, insurance remained a barrier, and vessels might not mobilize quickly; Platts assessed granular urea FOB Middle East at $656-$910/MT on April 16, up from $436-$494/MT on February 26 (S&P Global, April 17, 2026). The latest IMF PortWatch data I could access, with observations through April 26, showed Hormuz transits still depressed at 2-8 vessels per day on April 20-26 versus a 2023-2025 mean near 91 vessels per day, so the reopening narrative had not yet translated into normal flow by the last available shipping vintage (IMF PortWatch).
My final distribution is a mixture. I put 55% weight on a futures-anchored case centered at $625/ST, 20% on a persistent-tightness case centered at $690/ST, 15% on a fast-relief case centered at $520/ST, and 10% on an escalation or renewed-disruption case centered at $780/ST. This gives a mean near $638/ST, a median near $636/ST, a 10th percentile near $532/ST, and about 20% probability above $700/ST.
The obvious mistake is to use the last official IMF monthly value as the anchor. March 2026 was $378.04/ST, but April spot quotes had already moved into the high $600s, and the May futures contract was still at $631/ST at the start of May (Cbonds IMF subgroup mirror, ATS fertilizer update, April 6, 2026, Farmbucks fertilizer futures, crawled May 2026). The IMF lag is a reporting lag, not evidence that the physical market is still near $300/ST.
The second mistake is to set the center at $700 because April spot touched $700. A May monthly average above $700 needs persistence through most of May. The directly relevant May futures price is below that level, and CME settlement mechanics make that futures price more informative than generic global urea headlines (CME Urea U.S. Gulf FAQ). The right shape is a low-$600s center with a fat upper tail, not a point forecast at the April panic high.
The largest gap is that the resolution source has not published May 2026 and, as of this forecast, April 2026 was not yet cleanly visible in the IMF monthly download. The IMF may use a source and averaging convention that differs from public CME-linked pages, and the IMF itself says recent commodity observations can be revised (IMF FAQ).
The second gap is live physical-market opacity. ICIS, Profercy, and several barge-market assessments are proprietary. Public futures pages are useful but can be delayed, thin, or stale. The third gap is event risk. A durable reopening of Hormuz could pull May toward $550/ST; a failed ceasefire, insurance freeze, or new fertilizer tender could keep prices near or above $700/ST for long enough to move the monthly average outside the returned 250-700 bucket range.
Forecast: $614.26 per short ton
Supply Disruption: The closure of the Strait of Hormuz has significantly impacted urea supply, as it normally accounts for about 40% of global trade. Even if the strait reopens, shipping delays will prevent immediate relief.
China’s Export Restrictions: Ongoing bans and quota limitations from China will continue to restrict alternative supply sources until at least August 2026, further tightening the market.
Methodology Uncertainty: There is a notable discrepancy between the IMF’s previous price figures and current market prices, raising questions about how the IMF calculates its monthly averages. This adds a layer of unpredictability to the forecast.
Domestic Production: While U.S. producers are maximizing output, they cannot fully compensate for the lost imports from the Gulf, which keeps prices elevated.
Market Trends: Recent spot prices have shown an upward trend, with late April prices around $629 per ton. The forecast reflects this trend while accounting for potential fluctuations in May.
Geopolitical Factors: The trajectory of geopolitical events, including any potential ceasefires or resolutions, could influence price movements throughout May, but current conditions suggest sustained tightness.
Forecast (percentiles, aggregated):
Per-model forecasts:
Rationale: Summary The US Gulf NOLA urea spot price has experienced extreme volatility in the first half of 2026 due to geopolitical disruptions in the Middle East. Following a blockage of the Strait of Hormuz in late February, which disrupted approximately 40% of globally traded urea exports, prices spiked dramatically. The IMF benchmark rose from $263.02/st in February to roughly $378/st in March, while daily market spot prices and futures peaked above $700/st by mid-April. However, market conditions began to cool significantly toward the end of April. By April 30, physical spot assessments had fallen to $585/st, and CME May futures settled at $631 on May 1. The baseline expectation of $560/st for the May 2026 IMF average balances the lingering risk premium from the Middle East supply shock against the established downward momentum observed entering the month.
Strongest Arguments for Higher Values • CME May 2026 futures were still pricing at a robust $631/st at the start of the month, suggesting that financial markets anticipate prices remaining elevated throughout May. • The fundamental supply shock remains a reality; any escalation in the conflict could instantly halt the recent price correction and drive a secondary surge back above $700/st. • Spring planting season demand in North America could keep physical spot markets exceptionally tight, maintaining a high floor for the US Gulf NOLA benchmark.
Strongest Arguments for Lower Values • There is intense downward momentum entering May, highlighted by reports of a 14% single-day spot price drop and quotes falling to $585/st by late April. • Extreme price spikes in commodity markets often trigger rapid mean reversion as alternative supply chains adapt and speculative premiums wash out. • The IMF’s specific monthly averaging methodology often smooths out extreme intra-month peaks and can track slightly below the highest spot quotes or futures settlements.
Key Uncertainties • The duration and severity of the Strait of Hormuz disruption, which remains the definitive driver of current global fertilizer price levels. • The exact relationship and potential lag between late-April daily physical spot quotes and the final monthly average calculated by the IMF Primary Commodity Price System. • Demand destruction risks, as agricultural producers may significantly adjust application rates or substitute inputs in response to the massive April price spike.
As of Sunday, May 3, 2026, the IMF’s May 2026 number is not yet published. A YCharts page that mirrors the IMF series shows the official IMF/PCPS values at 232.51 USD/st for January 2026, 263.02 for February 2026, and 266.70 for May 2025, and it listed February 2026 as the latest official period with the next release scheduled for May 6, 2026. (ycharts.com)
The cleanest live market signal is the CME Urea (Granular) FOB U.S. Gulf contract for May 2026. Wright Ag showed the May 2026 contract at 631.0 on April 30, 2026, and Investing.com also showed the May 2026 contract at 631.00 with settlement day May 29, 2026. CME documentation says this contract settles to the arithmetic average of the month’s ICIS and Profercy price assessments, so it is a close proxy for a monthly NOLA average even if it is not literally the IMF series. (wrightag.com)
The fundamental backdrop is still tight. Reuters reported on March 13, 2026 that the U.S. was about 25% short of normal spring urea supplies and that New Orleans prices were materially below global prices, creating rerouting risk. Reuters then reported on April 17, 2026 that imported urea barges at New Orleans were being bought for export overseas because higher international prices made that profitable. (investing.com)
A higher-side reference point is the April 2026 NDSU Agricultural Trade Monitor. Using conditions as of April 13, 2026, it projected wholesale NOLA urea peaking at 782 USD/st under “Quick Reopening,” 784 under “Contested Transit,” and 996 under “Extended Conflict.” Its chart starts May 2026 already around the low-700s, but the report explicitly says these are model projections rather than observed market data. Because the later-traded May CME contract was around 631, I treat the NDSU path as an upside-risk indicator, not as the central estimate. (capts-ndsu.com)
The World Bank’s April 2026 Commodity Markets Outlook supports keeping that upside tail meaningful. It reported nitrogen (urea) prices averaging 725 USD/mt in March 2026, up nearly 55% from February, and said 2026 urea prices are projected to rise nearly 60% year over year, with risks tilted upward if shipping constraints or facility damage persist. (thedocs.worldbank.org)
My forecast therefore splits the month into three broad possibilities: quick easing that pulls the monthly IMF print toward the high-500s/low-600s; contested but improving logistics that keep it near the low/mid-600s; and renewed tightness that pushes the monthly average into the high-600s or above 700. My subjective mixture is 24% on a 595 center, 56% on a 635 center, and 20% on a 690 center. That implies an expected value of about 636 USD/st and leaves roughly an 11-12% chance of a print above 700. This is an inference from the traded May contract, Reuters-reported spot tightness, and the NDSU/World Bank high-price scenarios. (wrightag.com)
The resolution source is the IMF Primary Commodity Price System series for the monthly ‘US Gulf NOLA Urea Granular Spot Price, USD/ST’. The IMF’s commodity FAQ says monthly data are period averages and are updated on the Wednesday of the first full week of the following month, and Table 3 says this specific series is the average of weekly quotations. That matters because I am not forecasting a single spot print for one day in May 2026; I am forecasting the IMF’s monthly average of the weekly USDA-linked NOLA urea quotation for May 2026. (imf.org)
For recent official-history context, a public IMF mirror on YCharts shows May 2025 at 266.70 USD/ST, June 2025 at 221.77, December 2025 at 213.73, January 2026 at 232.51, and February 2026 at 263.02. So the market was still quite low through February 2026 before the spring shock. (ycharts.com)
The big new fact pattern is the 2026 fertilizer shock. The World Bank’s April 2026 Commodity Markets Outlook says nitrogen (urea) prices averaged $725/mt in March 2026, up nearly 55 percent from February, and projects 2026 urea prices to rise by nearly 60 percent year over year. The same report attributes the surge to Middle East shipping and production disruptions and says its baseline assumes the most acute phase of disruptions ends in May, with gradual normalization thereafter; it also explicitly flags upside risks if shipping constraints or conflict last longer. (thedocs.worldbank.org)
For the most current U.S. Gulf market signal, early-April FIS reporting showed NOLA urea April barges around 690 USD/ST, May around 675, and June around 630. FIS’s April 24 technical note put the May 2026 futures previous close at 657.5, while its May 1 note put the June 2026 futures previous close at 585 after a corrective decline. Barchart then showed the May 2026 U.S. Gulf urea futures contract at 631 on May 2, with a one-month high of 737.5 on April 15 and a low of 625 on April 29. In other words, the market spiked hard in April but had already retraced materially by the start of May. (fisapp.com)
The May futures contract is especially informative because CME says the U.S. Gulf urea contract is financially settled to the arithmetic average of daily ICIS and Profercy U.S. Gulf assessments during the contract month. That is not identical to the IMF series, which uses a monthly average of weekly USDA quotations, but it is close enough to be the best market-based anchor available. So I start near the May futures price and then widen for basis/methodology risk between daily ICIS-Profercy assessments and the IMF’s weekly USDA-based average. That makes a central value in the low 630s more plausible than either the early-April near-690 cash tone or the more bearish June futures around 585. This is an inference from the market structure and sources, not an IMF figure. (cmegroup.com)
I therefore use a three-scenario mixture. First, a 20% ‘quick normalization’ case centered near 565 USD/ST, reflecting the lower June futures level and the World Bank baseline that the acute disruption phase ends in May. Second, a 55% ‘current curve / partial normalization’ case centered near 630 USD/ST, anchored to the May futures market. Third, a 25% ‘renewed tightness’ case centered near 690 USD/ST, reflecting the World Bank’s upside-risk discussion and a University of Illinois farmdoc scenario note from April 29 that still showed very elevated NOLA urea paths under disruption scenarios, including peaks around 782-784 USD/ST in June-July even outside the most extreme case. I treat that farmdoc piece as an upside-scenario model, not as a direct spot quote. (fisapp.com)
Putting those together, my implied mean forecast is 632 USD/ST and the median is roughly 629 USD/ST. The distribution leaves most probability mass in the high-500s to high-600s, with a meaningful right tail above 700 because the market was still visibly headline-sensitive at end-April, but only a modest left tail below 550 because a full-month IMF average that low would likely require a very fast collapse from already-elevated early-May conditions. This final distribution is my synthesis of the sources above as of May 3, 2026. (barchart.com)
As of Sunday, May 3, 2026, the May 2026 IMF value is not yet published. The IMF commodity page says the data are updated monthly, and the IMF commodity specification table identifies the nitrogen benchmark relevant here as the US Gulf NOLA Urea Granular Spot Price in USD per short ton, averaged from weekly quotations. (imf.org)
For history, the IMF-linked monthly series mirrored by YCharts shows May 2025 at 266.70 USD/ST, then 222.63 in October 2025, 213.73 in December 2025, 232.51 in January 2026, and 263.02 in February 2026. An IMF-linked mirror also shows March 2026 at 378.04 USD/ST, implying the market had already turned sharply upward before April. (ycharts.com)
The backdrop is a genuine global supply shock. The World Bank’s April 2026 Commodity Markets Outlook says fertilizer prices rose in 2026Q1 driven mostly by urea and notes that, if risks materialize, average 2026 urea prices could exceed the 2022 average because of Middle East disruptions and natural-gas costs. Reuters likewise reports that roughly one-third of global fertilizer trade passes through the Strait of Hormuz, Qatar halted output at the world’s largest urea plant, and the global urea market was already tight because of European gas problems and Chinese export restrictions. (thedocs.worldbank.org)
That shock is clearly visible in U.S. Gulf indications. A U.S. fertilizer market summary put NOLA urea at 679-700 USD/ST on April 3. Fertilizerworks’ basket for granular urea FOB US Gulf was 727.15 on April 2, 790.90 on April 16, 757.55 on April 23, and 735.37 on April 30. I treat an April average in the mid-750s as a rough inference from those weekly observations, not as the eventual IMF figure, because the IMF uses a different weekly source. (advancedturf.com)
However, the forward curve points lower. On May 1, Farmbucks showed May 2026 U.S. Gulf urea futures at 631.00, June at 585.00, and July at 565.00. CME describes these contracts as settling to the arithmetic average of weekly ICIS and Profercy assessments during the contract month, so the May contract is a strong signal for the market’s expected May average even though the IMF resolves on a different weekly USDA/DataStream series. (farmbucks.com)
Two opposing forces dominate the forecast. Bullish: Reuters reported on April 17 that New Orleans urea was still about 170 USD/ST cheaper than overseas markets, encouraging resale of U.S.-bound cargoes abroad and keeping the domestic market tight. Bearish: the NDSU scenario work summarized by Pro Farmer says U.S. import exposure is heaviest from January through May and that, under a contested-transit case, prices begin to normalize by then. Combining those considerations with the backwardated futures curve, I use three scenarios: 20% fast normalization with a May IMF average near 560, 55% market-implied normalization near 632, and 25% sticky disruption near 690. That gives an expected value of about 632 USD/ST. (investing.com)
So my distribution is centered a little above 630, with only a modest left tail because a full-month May average below 500 would require a very rapid collapse from already-elevated late-April cash levels, and with a meaningful right tail above 700 if shipping, insurance, or production disruptions keep U.S. Gulf prices close to late-April spot readings for most of May. The code implements that view as a three-component normal mixture with mean about 632 and right skew. (fertilizerworks.com)
I am forecasting the IMF monthly average for the US Gulf NOLA Urea Granular Spot Price for May 2026, in USD per short ton. The official IMF commodity page says the data are updated monthly and currently points users to a March 2026 update file. YCharts, which republishes the IMF series, still showed the latest value as 263.02 USD/st for February 2026 and listed the next release for May 6, 2026. A separate IMF-linked market-data aggregator, Cbonds, already showed March 2026 at 378.04 USD/st. I therefore treat 378.04 as the best available read on the latest official monthly level, but I widen uncertainty because there is visible publication-lag inconsistency across IMF-linked redistributors. (imf.org)
The recent market signal is unmistakably upward. Argus reported early-March NOLA urea barges at roughly 490-550 USD/st fob, including first-half April volumes around 487-492 USD/st. ATS then reported NOLA urea at 630-690 USD/st for the week of March 20 and 679-700 USD/st for April 3. NitrogenSignal showed Gulf NOLA urea at 630 USD/mt as of April 15. StoneX said NOLA urea briefly fell nearly 20 percent in two days when the Strait of Hormuz briefly reopened, but an April 27 market note reported a rebound to roughly 690-695 USD/st. That pattern suggests a volatile but still tight market rather than a clean normalization. (argusmedia.com)
The broader fertilizer backdrop also argues for elevated May pricing. The World Bank wrote that fertilizer prices in March 2026 were at their highest since 2022 and projected urea prices to rise by nearly 60 percent in 2026, with risks of even higher prices if disruptions persist. Farmdoc’s April 29 summary of the NDSU scenario work says that, relative to a February 27 pre-crisis NOLA benchmark of 470 USD/st, urea remains well above that level in all scenarios; under Quick Reopening it peaks at 782 USD/st in June 2026, under the central Contested Transit scenario it peaks at 784 USD/st in July and stays above 700 through November, and under Extended Conflict it reaches 996 in October. Those are not the IMF monthly-average series itself, but they are strong evidence that the underlying spot market relevant to the IMF series is still under upward pressure heading into May. (thedocs.worldbank.org)
Historical IMF behavior matters too. In the 2022 fertilizer shock, the official IMF-linked monthly series moved from 584.00 in March 2022 to 629.05 in April and 627.05 in May, so a shock-driven spring surge did persist into May. In quieter years, May is often flat to somewhat above April: 2024 was essentially flat at 235.87 in both April and May, while 2025 rose from 231.28 in April to 266.70 in May. The main counterexample is 2023, when the market had already collapsed from the January spike before May arrived. So history does not support assuming a sharp May retracement just because spring application season is advancing. (ycharts.com)
My synthesis is: the old 2024-25 base rate would have suggested a May print near roughly 235-270 USD/st, but that base rate is now overwhelmed by the 2026 disruption. The most relevant anchor is the jump from February 2026 to March 2026 in the official series, plus the April physical-market evidence that NOLA remained far above March’s official monthly average. Because the IMF monthly average can print materially below the noisier physical prompt quotes, I do not map late-April spot levels one-for-one into the May IMF print. Instead, I treat May as most likely landing in the upper-400s, with meaningful downside if the April dip/brief reopening effect feeds through more than expected, and a meaningful right tail if shipping and supply constraints persist through the whole month. This is an inference from the March official value, the April market reporting, the World Bank outlook, and the NDSU/farmdoc scenario paths. (cbonds.es)
I encode that view as a 3-scenario mixture: 22 percent fast easing, 53 percent continued tightness, and 25 percent renewed squeeze. That produces a distribution centered around the high-400s; my approximate point estimate is 485 USD/st, with most of the probability mass between about 380 and 620 USD/st and only a small chance that the IMF May print exceeds 700 USD/st. This is deliberately wider than a pure spot extrapolation because the exact IMF monthly-average methodology and publication lag add nontrivial measurement uncertainty even when the directional market signal is clear.
As of Sunday, May 3, 2026, the IMF says its Primary Commodity Price System monthly data are updated in the first full week of each month. A mirror of the IMF series on YCharts shows February 2026 at 263.02 USD/st, and Cbonds shows the same IMF series at 378.04 USD/st for March 31, 2026; May 2025 was 266.70 USD/st. So the IMF series had already accelerated sharply before May 2026 began. (imf.org)
Current physical and futures indicators are much hotter than the latest IMF print. Fertilizerworks’ granular urea basket (an average of Green Markets, Fertecon, FMB, and Profercy midpoint prices) was 727.15 USD/st on April 2, 790.90 USD/st on April 16, and 735.37 USD/st on April 30. CME-linked market quotes were 680 USD/st for May 2026 on April 2, 705 USD/st on April 16, and 631 USD/st for May 2026 on April 30, with June 2026 at 585 USD/st on April 30. CME’s contract rules say final settlement is the arithmetic average of weekly ICIS and Profercy US Gulf assessments during the contract month, so I treat the May futures contract as the best near-term market anchor, though not as a one-for-one predictor of the IMF print.

Fundamentals support an elevated May reading. The World Bank’s April 2026 Commodity Markets Outlook says fertilizer prices reached their highest monthly level since 2022 in March 2026, projects urea up nearly 60% year over year in 2026, and notes supply disruptions in Iran and Qatar, very weak Chinese exports, and a baseline in which the most acute phase of Middle East disruption ends in May. A farmdoc/NDSU scenario paper published April 29 still projects NOLA urea peaking at 782 USD/st in June even in a “Quick Reopening” scenario, with much higher outcomes if disruption persists. That makes the right tail materially fatter than a simple mean-reversion model would imply. (thedocs.worldbank.org)
The hard part is translating those trade benchmarks into the IMF series, which has recently run well below broader market benchmarks. Using the visible IMF history, the 2025 IMF average was 230.88333333333333 USD/st, while the World Bank’s 2025 urea forecast converts to 383.7396013825512 USD/st, implying an IMF-to-benchmark ratio of 0.601666683609141. For March 2026, the IMF mirror shows 378.04 USD/st and the analogous converted ratio is 0.5742834122073233. Applying a roughly 0.57-to-0.60 mapping to the April 30 May futures price gives a value in the neighborhood of the high 300s, while applying it to the April 30 spot basket gives a value around the low 400s. Blending those anchors, keeping March IMF persistence in mind, and then adding a geopolitical upside tail, I land on a central estimate of 389 USD/st for the IMF May 2026 print. Most of my probability mass is in the mid-300s to mid-400s, with a smaller but real tail toward 500+ if the disruption proves more durable than futures imply. (cbonds.com)
