The Suez Canal and Bab el-Mandeb Strait have historically functioned as the primary shortcut between Asia and Europe, handling nearly 15% of global trade. Prior to late 2023, the Suez Canal and Bab el-Mandeb each averaged roughly 70 daily transits (500 weekly). The Cape of Good Hope was used primarily for bulk commodities or when Suez transit fees outweighed the fuel costs of the longer route. Following the onset of the Red Sea crisis in late 2023, a massive structural shift occurred. By early 2024, container traffic through the Red Sea had plummeted by 90%. A brief period of stabilization followed a Gaza peace plan in October 2025, but hostilities resumed on February 28, 2026, leading to a new ‘double blockade’ scenario involving the Strait of Hormuz. This has cemented the Cape of Good Hope as a primary trade corridor for 2026, with volumes reaching 112% above 2023 baselines.
My analysis is based on a structural shift in global maritime logistics that has persisted since late 2023 and escalated in early 2026. Prior to these disruptions, the combined weekly transit calls for the Suez Canal, Bab el-Mandeb, and the Cape of Good Hope totaled approximately 1,371 ships. Currently, as of late April 2026, this total has stabilized at a lower ‘crisis baseline’ of approximately 1,150 to 1,220 ships.
The most critical data point is the Macrobond/PortWatch report for the week ending April 26, 2026, which recorded a combined total of 1,218 ships (Suez: 291, Bab el-Mandeb: 252, Cape: 675). This period shows that while Suez and Bab el-Mandeb traffic is depressed by 40-50% compared to historical norms, the Cape of Good Hope has nearly doubled its volume, absorbing roughly 600-700 ships per week.
In weighting the forecast, I prioritized high-frequency weekly and daily data over monthly aggregates. While some PortWatch monthly proxies suggested a lower run-rate (~997/week in early April), the direct weekly observations from late April show a more robust recovery in total volume, driven largely by oil tankers bypassing the Strait of Hormuz and utilizing the Red Sea/Suez or Cape routes.
For the week of August 2, 2026, I anticipate the current ‘crisis regime’ will persist. Qualitative evidence from major carriers like Hapag-Lloyd and Maersk indicates that rerouting instructions remain in place. Furthermore, World Bank projections suggest that a return to pre-war transit levels is not expected until at least October 2026. Therefore, the total volume is unlikely to return to the 1,370+ baseline.
I center the forecast near 1,169 ships, which aligns with the January-April 2026 mean (1,153) while acknowledging the slightly higher volumes seen in late April. The 50% HDI (1,135 to 1,204) reflects the inherent weekly volatility in AIS signal captures and vessel scheduling. The downside risk (represented by the lower tail) accounts for potential renewed kinetic escalations that could temporarily close the Bab el-Mandeb, as threatened by Houthi forces in April 2026. The upside risk accounts for a ‘partial normalization’ where some container traffic returns to the Suez before the Cape diversions fully ramp down, creating a temporary surge in the combined sum.
Question: will the combined weekly raw PortWatch transit calls through Suez Canal + Bab el‑Mandeb + Cape of Good Hope during 27 Jul–2 Aug 2026 be materially higher or lower than current levels? This is primarily a route‑choice question (a Red Sea transit typically counts at both Bab and Suez, while a Cape reroute counts only once), so route‑share shifts matter more than modest changes in global trade volume. Forecasters use the IMF/World Bank PortWatch backend (raw daily ArcGIS chokepoint counts summed over the target week, not MA7) and anchor on a mid‑April mirrored MA7 ≈ 38.6 Suez + 33.4 Bab + 90.9 Cape → ~1,140 combined weekly calls. Across teams the key signals agree: major carriers’ partial January returns were reversed by March, security/war‑risk warnings and much higher insurance premia persist, and the Suez toll rebate for very large containerships was suspended in April—together implying the Cape‑heavy regime is likely to persist into late July. Historical analogues (Somali piracy, prolonged Suez closures) and the stickiness of carrier routing support a slow unwinding, so most forecasters place the highest mass in a “status‑quo” band near ~1,120–1,160 with modest right and left tails for partial recovery or further deterioration; they note isolated MSC service moves are weaker signals than sustained carrier advisories. Important caveats: PortWatch near‑real‑time data are subject to revision and AIS issues (jamming, going dark) can distort chokepoint counts, and week‑boundary slippage between Bab and Suez adds noise to the raw weekly sum.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the main approach is to start from PortWatch-style baseline traffic levels and then adjust for how Red Sea disruption shifts shipping between routes. The combined weekly total is anchored around a normal baseline of roughly 1,300 calls, with early-crisis levels closer to about 1,125, and the expected outcome for late July/early August 2026 is placed between those two.
The dominant reasoning pattern is that diversion away from the Suez Canal and Bab el-Mandeb remains the key driver, while the Cape of Good Hope absorbs some of that displaced traffic. In other words, the forecasts assume continued rerouting rather than a full return to normal patterns. One model expresses this with route-specific multipliers: Suez and Bab stay depressed, Cape remains elevated. Another emphasizes carrier behavior, project cargo flow through southern Africa, and market signals as evidence that diversion pressure persists into mid-2026.
There is broad agreement on the central estimate: the total combined weekly count should be below baseline, most likely in the mid-1100s to low-1200s. The main difference is in how much recovery is expected by the target week: one forecast is slightly more optimistic, near 1,215, while the other is closer to 1,165 and assumes more persistent disruption.
Uncertainty is framed as two-sided but skewed around ongoing instability:
Overall, the forecasts converge on a view of partial recovery at most, with sustained diversion effects keeping the combined weekly transit total below pre-crisis norms.
— Iteration 2 — The forecasts converge on a central estimate of roughly 1,200 combined weekly transit calls, with most of the probability mass in the ~1,100–1,300 range for the week ending August 2, 2026.
Overall, the shared view is a continued-disruption regime with sustained Cape rerouting, producing a combined weekly total near 1,200, with only moderate chances of a meaningful move outside the ~1,100–1,300 band.
— Iteration 3 — The forecasts converge on a mid-to-high 1,100s weekly total as the most likely outcome, with the estimate driven mainly by PortWatch-style traffic baselines and the expectation of only partial recovery by late July 2026.
The shared view is that the week ending August 2, 2026 will likely reflect persistent partial disruption, with totals near the upper end of the crisis baseline, but still sensitive to any shift between Red Sea rerouting and Cape diversion.
Summary of Rationale Arguments
The “2-for-1” Mathematical Baseline The forecasters universally emphasize a structural arithmetic quirk in how transit calls are counted across these three chokepoints. Under normal circumstances, a vessel traveling between Asia and Europe via the Red Sea registers two transit calls (one at the Bab el-Mandeb Strait and one at the Suez Canal). However, a vessel diverting around Africa registers only one transit call at the Cape of Good Hope. Consequently, the mass diversion of global shipping away from the Red Sea inherently suppresses the combined aggregate total, even if overall global trade volumes remain constant.
Geopolitical Stickiness and Routing Reality There is broad consensus that a mass return of commercial shipping to the Red Sea by August 2026 is highly improbable. Major ocean carrier alliances have already baked Cape of Good Hope detours into their summer schedules due to persistent security risks. A baseline of Red Sea traffic will remain, consisting mostly of regional vessels, “shadow fleet” tankers, and opportunistic dry bulk carriers, establishing a firm floor. Furthermore, disruptions around the Strait of Hormuz have pushed additional energy traffic around the Cape, creating an artificially elevated baseline for that route unless a diplomatic resolution is reached.
Macroeconomic and Seasonal Dynamics While late July and August traditionally mark the onset of the Q3 peak shipping season—which should theoretically drive up transit volumes—forecasters expect this seasonal bump to be muted. To compensate for longer Cape detour times, Western importers have structurally “front-loaded” their holiday cargo into the spring and early summer. Combined with broader macroeconomic cooling, high fleet overcapacity, and the active use of “blank sailings” (canceled voyages) by carriers, physical transit growth is expected to be modest.
Weather and Methodological Risks The rationales highlight two major sources of volatility for the target week:

The research examines the projected combined weekly transit calls through the Suez Canal, Cape of Good Hope, and Bab el-Mandeb Strait for the week ending August 2, 2026, in light of significant geopolitical disruptions. Two major events have influenced shipping traffic: the ongoing Houthi Red Sea Crisis, which led to a drastic reduction in Suez Canal and Bab el-Mandeb traffic, and the US-Israel conflict with Iran, which prompted further diversions of shipping routes around the Cape of Good Hope. The analysis includes recent traffic data, showing a marked decrease in container ship transits through the Suez Canal and Bab el-Mandeb, while traffic around the Cape has surged.
Estimates for weekly transit calls are provided based on pre-crisis baselines and current data, suggesting a range of 850 to 1,250 total calls, depending on various factors such as military escalation, global trade conditions, and potential ceasefires. The research highlights the uncertainty surrounding these projections, with expert commentary indicating that traditional trade patterns may not fully return even if geopolitical tensions ease.
Sources used in the research include:

The shipping environment has undergone two major disruptions that are directly relevant:
Houthi Red Sea Crisis (late 2023–ongoing): Houthi attacks on commercial vessels beginning in December 2023 caused Suez Canal traffic to fall from ~26,000 ships in 2023 to ~13,000 in 2024 — roughly a 50% decline. Bab el-Mandeb traffic experienced similar drops. Cape of Good Hope traffic roughly doubled from 2023 levels as ships diverted. [6][9]
US-Israel War with Iran (February 28, 2026–ongoing): The US and Israel launched strikes on Iran, prompting Iran to threaten closure of the Strait of Hormuz. This triggered a second, compounding wave of diversions. All major container carriers — Maersk, Hapag-Lloyd, CMA CGM, and MSC — suspended Suez Canal and Bab el-Mandeb transits and rerouted around the Cape of Good Hope. [11][12][13]
A brief recovery period followed the October 2025 Israel-Hamas ceasefire: the Suez Canal Authority reported a 5.8% increase in ship transits and a 16% rise in net tonnage in January 2026 versus the prior year. However, traffic was still 30-35% below pre-crisis levels, and this recovery was reversed by the February 2026 escalation. Hapag-Lloyd’s CEO confirmed the company had to halt “first cautious attempts” to return to the Suez route. [9][14]
IMF PortWatch-referenced data (from BFMTV citing Kpler & IMF PortWatch):
All vessel types (Cape of Good Hope):
Suez Canal:
Using the background information provided and the data gathered:
Pre-crisis baselines (2023): | Chokepoint | Weekly Transit Calls | |—|—| | Suez Canal | ~500 | | Bab el-Mandeb | ~500 | | Cape of Good Hope | ~200–300 (estimated baseline for bulk) | | Total | ~1,200–1,300 |
During Houthi crisis (2024–early 2025): | Chokepoint | Estimated Weekly | |—|—| | Suez Canal | ~200–275 (down 50–60%) | | Bab el-Mandeb | ~175–250 (down 50–65%) | | Cape of Good Hope | ~400–550 (roughly doubled) | | Total | ~775–1,075 |
Current period (March–May 2026, post-Iran war escalation): The PortWatch-referenced data suggests container ship transits through Suez+Bab el-Mandeb fell to ~5/day combined, but total transit calls (all vessel types) would be significantly higher than container-only counts. Adjusting for the full vessel mix:
| Chokepoint | Estimated Weekly Range |
|---|---|
| Suez Canal | ~150–250 (further depressed) |
| Bab el-Mandeb | ~150–250 (further depressed) |
| Cape of Good Hope | ~550–750 (massive surge, possibly higher) |
| Total | ~850–1,250 |
Polymarket: “2k+ container ship transits of Suez Canal in H1 2026?” — Priced at ~2% Yes (near-certain No), with ~$137,000 volume. This strongly indicates market consensus that Suez container transits will remain deeply depressed through mid-2026. [22]
Polymarket: “Will Suez Canal traffic recover to pre-Houthi levels before July/September [2025]?” — Both resolved No at effectively 0%. The July market had ~$224,511 volume and used IMF PortWatch as the resolution source (7-day moving average of ≥70 vessels/day). These provide useful precedent for how the PortWatch data aligns with market expectations. [23][24]
No prediction market was found specifically targeting the combined three-chokepoint transit calls for the week ending August 2, 2026.
Factors favoring lower totals (~800–950):
Factors favoring higher totals (~1,050–1,250+):
Factors favoring the middle range (~950–1,050):
The combined weekly transit calls have likely been running in the range of 850–1,150 in recent weeks (March–April 2026), with the total being somewhat conserved as traffic diverts from Suez/Bab el-Mandeb to the Cape, but with a net reduction due to longer routes reducing round-trip frequency.
For the week ending August 2, 2026, the key swing factor is whether the Iran war sees any de-escalation. Prediction markets overwhelmingly suggest Suez will remain depressed through at least mid-2026, and expert commentary from shipping executives suggests pre-war trade patterns “may not fully return to their previous levels” even after a peace agreement. [5] The central estimate likely falls in the 900–1,100 range, though significant uncertainty remains given the volatile geopolitical situation three months out.
1. Residual Internal Inconsistency: The critic is absolutely right. My scenario weights mathematically imply a weighted average of ~1,005, yet I had my median at 1,045 - a 40-ship gap that reveals lingering optimism bias I couldn’t justify.
2. Refined Mechanistic Calculation: The critic’s more precise calculation showing current baseline around 900-950 is compelling:
This is the strongest analytical anchor I have.
1. Cape Traffic Surge May Be Higher: The research mentions Cape traffic has “roughly doubled” and could be running 550-750/week for all vessel types. This suggests the mechanistic baseline might be closer to 1,000-1,050 when accounting for actual Cape surge data.
2. Fleet Adaptation Effects: The critic’s own “hot take” about additional vessels deployed on longer Cape routes is valid. Shipping companies have added capacity to maintain service frequency, which could marginally increase weekly transit counts.
3. Seasonal Timing: Pre-Q3 peak shipping season provides modest upside potential.
After three rounds of rigorous critique, I’ve arrived at several conclusions:
The critic’s suggested distribution with median at 1,025 is well-calibrated. It:
I’m adopting the critic’s distribution as it represents the best synthesis of all analytical approaches discussed across three rounds.
Conditioning: This forecast is conditioned on the question not being annulled (i.e., IMF PortWatch publishes data by August 12, 2026).
Updated prediction: Percentile 0.1: 620 Percentile 1: 720 Percentile 5: 820 Percentile 10: 875 Percentile 20: 935 Percentile 30: 975 Percentile 40: 1005 Percentile 50: 1025 Percentile 60: 1060 Percentile 70: 1105 Percentile 80: 1170 Percentile 90: 1270 Percentile 95: 1370 Percentile 99: 1520 Percentile 99.9: 1680
Looking at the critic’s analysis, I need to carefully evaluate each point and update my forecast accordingly.
1. Cape of Good Hope Traffic Underestimation The critic is absolutely right. The data points showing 130-150 ships/day at Cape (April 2026) translate to 910-1,050 ships/week - significantly higher than my initial estimate of 550-750. I underweighted these specific figures in my original analysis.
2. Double-Counting Effect This is an excellent point I didn’t adequately incorporate. Ships traversing the full Red Sea route appear in BOTH Suez AND Bab el-Mandeb counts. When they divert to Cape, the combined metric loses this “double-count,” but gains a single Cape count. This structural effect helps explain why the aggregate doesn’t collapse as dramatically as individual chokepoint drops might suggest.
3. Question Creator’s Range The creator’s suggested 1,100-1,300 range carries informational value. My original median of 1,070 fell below this range, which was too conservative given available evidence.
4. Seasonal Factors Late July represents the start of Q3 peak shipping season for holiday inventory. I should weight this upward pressure more heavily.
I still believe maintaining meaningful downside tail risk is appropriate. The Iran-US conflict remains volatile, and three months provides ample time for:
The Polymarket signals showing near-certainty of continued Suez depression remain valid constraints on upside scenarios involving rapid Red Sea recovery.
Reconciling the data: If Cape traffic is genuinely ~950/week currently, and Suez+Bab el-Mandeb combined are ~350-400/week (accounting for high correlation between them), current totals are likely 1,300-1,350 - higher than my original estimates but consistent with the creator’s range.
The conservation principle holds better than I initially modeled: global shipping demand hasn’t collapsed, just rerouted. The Cape surge largely compensates for Red Sea losses in the combined metric.
I’m shifting my distribution upward with a median around 1,120, reducing extreme downside probabilities while maintaining reasonable tail risk for geopolitical deterioration.
Updated prediction:

1. Upper Tail Structural Inconsistency - This is the most compelling point. The 99.9th percentile at 1,700 is economically incoherent. Pre-crisis totals were ~1,200-1,300 WITH double-counting. If Suez reopens, ships leave Cape route—you can’t maximize both simultaneously without a 40%+ global trade surge in 3 months. I must compress this tail significantly.
2. Median Positioning - The question creator’s range of 1,100-1,300 (midpoint 1,200) likely reflects recent PortWatch data access. My median at 1,115 near their floor is overly conservative. Shifting to ~1,125-1,130 better respects this signal.
3. “Steady State” Argument - This is an insightful structural observation. By August 2026:
Industry inertia means traffic patterns won’t shift dramatically in weeks, even with peace news. This suggests lower variance than I projected—we’re likely locked into a predictable band.
Left Tail Preservation - The US-Iran ceasefire remains fragile. Major escalation (Hormuz closure, intensified Houthi attacks) could materialize. The 5th percentile at ~885 appropriately captures this risk without being excessive.
Revised estimates (conditional on non-annulment):
Updated prediction: Percentile 0.1: 720 Percentile 1: 800 Percentile 5: 885 Percentile 10: 950 Percentile 20: 1015 Percentile 30: 1060 Percentile 40: 1095 Percentile 50: 1125 Percentile 60: 1160 Percentile 70: 1195 Percentile 80: 1240 Percentile 90: 1310 Percentile 95: 1375 Percentile 99: 1490 Percentile 99.9: 1580
The critic continues to make compelling points. Let me address them systematically.
1. Persistent Central Estimate Optimism: This is fair. The research states 900-1,100 range (midpoint ~1,000). Even with 5-10% seasonal adjustment, this yields ~1,050-1,100, not 1,150. I was still anchoring too high on the question creator’s range.
2. Market Signal Inconsistency: The 2% Polymarket probability strongly indicates status quo (depressed traffic) is the baseline expectation. My median should reflect this, not price in recovery scenarios as the baseline.
3. “Conservation of Traffic” Problem: This is an important structural insight. The 14-day longer Cape route means each ship makes ~27% fewer annual voyages. This isn’t just temporary diversion—it’s a genuine reduction in weekly chokepoint throughput that I underweighted.
4. Table vs. Text Discrepancy: The research shows 850-1,250 in the table but 850-1,150 in text. Taking the conservative interpretation gives midpoint ~1,000.
1. Fleet Deployment Responses: Shipping companies have been adding vessels to Cape routes to maintain service frequency. This partially offsets the conservation problem (though not completely).
2. Chinese Shipping Floor: Chinese vessels continue using Red Sea routes, providing a floor for Suez/Bab el-Mandeb traffic that limits catastrophic downside.
3. Three-Month Uncertainty: August 2026 is far enough out that both escalation and de-escalation scenarios have meaningful probability mass.
Following the math more rigorously:
This suggests median should be approximately 1,080-1,100, not 1,150 or even 1,120.
I’m dropping my median by ~35-40 points to ~1,105. This better reflects:
The distribution width seems appropriate given the conflict volatility—I’ll maintain similar tail calibration while shifting the center downward.
Updated prediction: Percentile 0.1: 615 Percentile 1: 770 Percentile 5: 895 Percentile 10: 965 Percentile 20: 1025 Percentile 30: 1060 Percentile 40: 1085 Percentile 50: 1105 Percentile 60: 1135 Percentile 70: 1180 Percentile 80: 1255 Percentile 90: 1365 Percentile 95: 1485 Percentile 99: 1645 Percentile 99.9: 1835
The critic continues to raise valid points that merit further consideration.
Sequential Chokepoint Counting: This is a crucial insight I hadn’t fully internalized. The resolution specifically asks for “sum of Transit Calls” for all three chokepoints. A vessel transiting the Red Sea passes through both Bab el-Mandeb AND Suez, meaning the same ship is counted twice. This methodological point substantially affects my central estimate upward.
Question Creator’s Midpoint: My median at 1,155 sits at roughly the 27th percentile of the creator’s 1,100-1,300 range. Given the creator likely has familiarity with PortWatch data patterns, I should give this signal more weight. A median closer to 1,175-1,200 is more appropriate.
Traffic Conservation Math: The logic is sound:
My 1,155 median was at the floor of this range.
Left Tail Risk: The ongoing US-Israel-Iran conflict creates genuine downside scenarios. A major escalation could impact all three chokepoints simultaneously. My P20 below 1,000 remains justified.
Methodological Uncertainty: Terry Gale’s 150/day Cape figure may use different counting methodology than PortWatch. Some discount is warranted, though perhaps not as severe as my initial estimate.
Double-Counting as Feature, Not Bug: The question explicitly sums transit calls across sequential chokepoints. Even with depressed Red Sea traffic, if Suez and Bab el-Mandeb each show ~175/week (same vessels, counted twice), that’s 350 from Red Sea routes alone. Add 850+ from Cape, and 1,200 is readily achievable.
Mine Clearance Catalyst: The Pentagon’s 6-month timeline from February 2026 suggests potential clearing by August - creating a genuine upside catalyst right at our target date.
Seasonal Demand Pressure: August pre-peak season creates natural demand that must be absorbed somewhere.
The critic has convinced me to shift upward by approximately 15-20 ships across most percentiles. The sequential counting methodology and the question creator’s signal both point toward a higher central estimate around 1,170-1,175.

Base Rate: April 19, 2026 IMF PortWatch 7-day MA combined: Suez 36.14/day + Bab el-Mandeb 32.86/day + Cape 93.43/day = 162.43/day = ~1,137/week. Pre-Hormuz-crisis early-Feb 2026 estimate ~1,050/week (Red Sea recovery in progress, Cape elevated but declining). Pre-Houthi-crisis 2023 baseline estimated ~1,175/week.

Reviewer Panel:
Reviewer (reasoning)
The forecast rests too heavily on an April 7-day moving average to extrapolate into late July without accounting for known seasonal shipping cycles or more recent weekly data, and it misapplies the diversion math (assuming each diverted vessel subtracts two calls from Suez/Bab but only adds one at the Cape without adjusting for round-trip accounting).
Objections:
Reviewer (calibration)
The forecast’s reasoning contains a significant internal inconsistency regarding Bab el-Mandeb transit calls. Grounding facts state both that Bab el-Mandeb’s total 7-day moving average was 32.86 ships/day as of April 19, 2026, and that over 1,260 oil tankers transited Bab el-Mandeb in March 2026 (implying ~40.6 oil tankers/day). It is impossible for the total daily transits to be lower than the oil tanker transits alone for an overlapping period, which fundamentally undermines the baseline calculation for this critical chokepoint. Additionally, the forecast may be too conservative about potential shifts given the 3-month timeline and the structural dynamic where traffic returning to Red Sea routes increases the combined total.

Adjustment Rationale:
Adjustments from draft: (1) Verified IMF PortWatch baseline via MacroMicro: Suez Canal 7-day MA 36.14/day, Bab el-Mandeb 32.86/day, Cape of Good Hope 93.43/day on April 19, 2026 — combined ~1,137/week. (2) Dropped unsupported Lloyd’s List ‘1,260 oil tankers’ claim flagged by fact-checker; this resolves the calibration reviewer’s internal-inconsistency objection (the Bab el-Mandeb total is now coherent without the contradicting tanker figure). (3) Confirmed Hormuz crisis began Feb 28, 2026 (Operation Epic Fury, US-Israel strikes on Iran) and is ongoing as of May 2, 2026; container carriers suspended Suez transits and diverted to Cape; disruption ‘expected to persist through 2026’ per industry analyst consensus. (4) Widened distribution and lowered confidence to ‘low’ per calibration reviewer — Hormuz resolution timing, Red Sea container return, and Q3 seasonality all add real uncertainty across a 3-month forecast horizon. (5) The reasoning reviewer’s request for June-July 2026 PortWatch data is impossible to fulfill — today is May 2, 2026, so that data doesn’t exist yet. Center kept near 1,140 (slight upward drift from baseline reflecting Q3 container peak season offsetting any marginal Cape decline if Red Sea returns inch forward). The structural diversion asymmetry (Red Sea routing = 2 calls per voyage, Cape = 1) means combined sum modestly increases if Red Sea recovers and decreases if more diversion occurs — adds two-tailed risk.

Model’s Answer: The best anchor is the most recent exact-metric data derived from IMF PortWatch, not the looser background summaries. The strongest inputs here are the April 19, 2026 daily transit-call averages for the exact three chokepoints: about 36.1 for Suez, 93.4 for the Cape of Good Hope, and 32.9 for Bab el-Mandeb. Multiplied by seven, that implies a current combined weekly level near 1,137.
The key structural point is that this question is not asking for unique ships. A ship using the Red Sea route is typically counted twice in the combined total, once at Bab el-Mandeb and once at Suez, while a ship diverting around the Cape is counted once. That means a return from Cape routing to Red Sea routing can raise the combined total materially even if total world shipping demand barely changes. This creates a somewhat fatter right tail than a naive “traffic stable, so total stable” view would suggest.
My base case is still persistence. The highest-quality recent context says the Red Sea security problem remained unresolved through late March and April 2026, with major carriers still largely avoiding the route. Three months is enough time for some geopolitical movement, but not so much time that a dramatic and trusted normalization should be the default. Shipping networks also do not snap back instantly after a security improvement. So the modal outcome is that late-July traffic looks broadly similar to mid-April, with only modest drift from seasonality and ordinary week-to-week variation.
I put somewhat more weight on a small upward drift than a small downward drift because late July is not a weak seasonal window for shipping, and because even a modest thaw in Red Sea risk can mechanically lift the combined total. But I do not put large weight on a full rebound by August. Conversely, the downside remains meaningful because there is still room for the residual Red Sea traffic to fall further, and weekly data can move around due to idiosyncratic scheduling, weather, and market softness.
The assumptions that matter most are these. First, that Red Sea security conditions remain broadly similar through the target week; I think this has about a 75 percent chance of being basically right, and about a 25 percent chance of being wrong enough to move the total a lot. Second, that the April 2026 PortWatch-derived level is representative of the current regime rather than a temporary local fluctuation; I assign about an 80 percent chance that this is a good anchor, with a 20 percent chance that recent unseen data would imply a shifted baseline. Third, that global shipping demand stays near current levels; I put roughly an 85 percent chance on that, with a 15 percent chance of a macro or trade shock materially changing volumes.
A low outcome would most likely come from a renewed deterioration in Red Sea security, fewer tanker and bulk transits through Bab el-Mandeb and Suez, or a soft global trade week. I think outcomes below 1,100 are clearly possible and not just token-tail possibilities. A high outcome would most likely come from partial de-escalation leading some traffic back toward the Red Sea while Cape traffic remains elevated during a transition period; because of the double-counting structure of Suez plus Bab el-Mandeb, this can lift the combined sum quickly. But getting well above 1,300 still looks unlikely by early August.

Forecast (percentiles, aggregated):
Per-model forecasts:
Rationale: Summary The baseline combined weekly transit calls across the Suez Canal, Bab el-Mandeb Strait, and Cape of Good Hope currently sit at approximately 1,137 ships (based on April 2026 data). This reflects a structural shift in global shipping routes: vessels diverted around Africa only trigger one transit call at the Cape of Good Hope, whereas voyages through the Red Sea trigger two calls (one at Bab el-Mandeb and one at Suez). Therefore, the ongoing Red Sea shipping crisis mechanically depresses the aggregate count. The median estimate of 1,158 anticipates a slight increase from current baseline levels. This reflects marginal improvements in regional stability following recent ceasefires, paired with typical seasonal shipping growth expected by late summer. The distribution heavily leans toward the baseline status quo of sustained African diversions, as major carriers continue to treat the Cape as the default route due to persistent security concerns.
Strongest Arguments for Higher Values • A partial or complete return of commercial traffic to the Red Sea route would rapidly inflate the aggregate count, as returning vessels would once again trigger two transit calls instead of one. • General improvements in global macroeconomic conditions or a robust late-summer surge in trade volumes between Asia and Europe could drive increased overall shipping traffic regardless of the chosen route. • Easing of regional tensions could encourage a subset of specialized or risk-tolerant shipping operators to resume Suez transits, pushing the weekly total toward the 1,200 to 1,250 range.
Strongest Arguments for Lower Values • A breakdown of the recent ceasefire or renewed geopolitical escalation could trigger further declines in overall shipping velocity, similar to the disruptions seen in March 2026 when combined weekly calls dropped to roughly 970. • Structural supply chain adjustments over the past years may have reduced the total number of distinct voyages needed, as companies optimize for the longer Cape route by deploying larger but fewer vessels. • Elevated insurance premiums and sustained security risks might permanently deter any residual traffic currently utilizing the Red Sea, forcing the remaining vessels to the single-count Cape route.
Key Uncertainties • The durability of regional ceasefires and the broader security environment in the Middle East, which directly dictates carriers’ willingness to return to the Red Sea. • The exact timeline of any potential Red Sea reopening, and how quickly major ocean freight alliances can pivot their schedules back to the Suez Canal. • Macroeconomic variables influencing overall trade volumes between Europe and Asia by August 2026.
I interpret the target exactly as the IMF PortWatch weekly sum of transit calls for the Suez Canal, the Cape of Good Hope, and the Bab el-Mandeb Strait for Monday, July 27, 2026 through Sunday, August 2, 2026. The World Bank’s PortWatch methodology page is useful because it gives a clean historical reference: in the pre-crisis baseline period from January 1, 2022 to October 6, 2023, average daily transit calls were 70.07 for Suez, 70.77 for Bab el-Mandeb, and 46.01 for the Cape, or 186.85 combined per day = 1307.95 per week. During the initial Red Sea crisis period from November 17, 2023 to February 19, 2024, those averages shifted to 48.85, 42.95, and 68.95 respectively, or 160.75 combined per day = 1125.25 per week. That gives a reasonable historical lower crisis regime and upper pre-crisis regime for this question. (datapartnership.org)
The best current PortWatch-style anchor I found is the IMF series surfaced by MacroMicro for April 12, 2026. The 7-day moving-average transit calls were 38.57/day for Suez, 33.43/day for Bab el-Mandeb, and 90.86/day for the Cape of Good Hope. Summed together, that is 162.86/day, which converts to 1140.02 over a seven-day week. So as of mid-April 2026, the combined total was still much closer to the disrupted-crisis regime than to the pre-crisis regime. (en.macromicro.me)
Independent maritime-intelligence data tell a very similar story. JMIC’s week-11 dashboard, using S&P Global data for cargo-carrying vessels in international trade/transit, showed that the week ending March 15, 2026 had 247 Suez transits, 153 Bab al-Mandeb transits, and 731 Cape of Good Hope transits, for a combined 1131. The same dashboard noted week-over-week declines after the February 28, 2026 outbreak of regional hostilities. Separately, Lloyd’s List reported that January 2026 still had 1,079 cargo-carrying vessels through Bab el-Mandeb and 924 through Suez, both above January 2025 levels, which implies that some recovery had been underway before the late-February shock. (dbce.org)
The directional forces between now and late July 2026 are mixed. On the recovery side, Maersk and Hapag-Lloyd announced on February 3, 2026 that one Gemini service would route through the Red Sea and Suez Canal, and Maersk said on February 5, 2026 that a gradual resumption of shorter Red Sea routes was one reason 2026 freight conditions were easing. On the negative side, CMA CGM said on February 28, 2026 that passage through the Suez Canal was suspended until further notice and affected vessels would be rerouted via the Cape of Good Hope, and Maersk said on March 1, 2026 that it would pause future Trans-Suez sailings. As of the JMIC advisory dated April 5, 2026, the overall regional maritime risk level remained critical, although Bab el-Mandeb and the Gulf of Aden were assessed only at a moderate threat level and JMIC said there had been no confirmed incidents affecting maritime traffic there; Lloyd’s List also quoted EUNAVFOR ASPIDES saying operators need at least three months to reschedule contracts and that insurance surcharges remain a major constraint on a fuller return. (investing.com)
My synthesis is to start from the current PortWatch-style weekly anchor of about 1140 and then add only a modest upward drift by late July. The reason is that July 27 to August 2, 2026 is far enough after the April 5, 2026 advisory for some schedules and insurance decisions to be reset, but probably not far enough for a broad-based return to the pre-crisis routing mix. This question is especially sensitive to routing choice because a ship that goes via the Red Sea corridor is effectively counted twice in the combined total (Bab el-Mandeb plus Suez), while a diversion around the Cape contributes only one of the three chokepoint counts. So even partial carrier returns can raise the weekly total materially, but a full return toward the pre-crisis ~1308/week would require much stronger geopolitical and insurance normalization than the evidence currently supports. (datapartnership.org)
I therefore used a four-scenario mixture in the code: persistent caution or renewed dips (35%), slow normalization (40%), stronger normalization (20%), and upside normalization (5%). That mixture centers the distribution at roughly 1165 total weekly transit calls. In plain language: I expect late-July/early-August 2026 to be somewhat above the mid-March/mid-April 2026 trough-like readings, but still clearly below a full pre-crisis routing mix. The distribution keeps a meaningful downside tail below 1100 in case regional risk re-escalates, and only a small upside tail above 1300 because that would require a much broader and faster restoration of confidence than current conditions suggest. (en.macromicro.me)
PortWatch is the right source here: it is the IMF/University of Oxford platform for AIS-based chokepoint data, and the World Bank API notebook confirms the daily chokepoint dataset and transit-call definition. In that dataset, a transit call is counted when a ship crosses the chokepoint boundary, with a 48-hour threshold before the same ship is counted again. (imf.org)
A good base rate comes from the World Bank red-sea monitoring notebook built directly on PortWatch data. Using January 2022 to October 2023 as the reference period, average daily transit calls were 70.07 at Suez, 70.77 at Bab el-Mandeb, and 46.01 at the Cape of Good Hope. That implies a pre-crisis combined weekly baseline of about 1,308 calls. In the Red Sea crisis period through September 2024, those averages shifted to 48.85, 42.95, and 68.95 respectively, implying a combined weekly level of about 1,125. The key structural point is that a Europe-Asia ship using the Red Sea tends to be counted twice in this contract, once at Bab el-Mandeb and once at Suez, while a Cape diversion is counted only once, so any normalization of Red Sea routing mechanically pushes the combined total upward even if underlying trade volume is unchanged. (datapartnership.org)
More recent evidence shows the system stayed disrupted well into 2025. A World Bank MENAAP monitor dated July 31, 2025 says Suez averaged 230 ships per week in the first two weeks of July 2025, versus more than 500 ships per week in 2023, while Cape traffic remained above historical levels; its accompanying chart also shows Bab el-Mandeb still far below pre-crisis levels and the Cape far above them. (thedocs.worldbank.org)
There was some recovery in Suez late in 2025, but not a full normalization. The IMF’s February 2026 Egypt staff report says Suez Canal trade activity was gradually recovering, and its Figure 3 shows monthly Suez traffic rising through late 2025. But the IMF’s April 29, 2026 blog still said Bab el-Mandeb transits were stuck at roughly half their pre-attack level more than two years after the initial attacks, underscoring how sticky the rerouting has become. (imf.org)
For the forward-looking part, I treat the next three months as mostly a question of route stickiness, not a full network reset. Reuters-reported rerouting by CMA CGM early in 2026 and Ocean Alliance’s decision to maintain Cape routing for 2026 both point to carriers still planning around Red Sea risk rather than betting on a rapid return to pre-2023 patterns. (marketscreener.com)
My scenario model is therefore: 65% probability of a status-quo summer with partial recovery but continued avoidance by many liner services, centered around Suez 285, Bab el-Mandeb 240, and Cape 665, for a combined weekly total near 1,190; 20% probability of renewed disruption that pushes more traffic toward the Cape and drags the combined total down toward about 1,100; and 15% probability of a more meaningful de-escalation that lifts Red Sea usage faster than expected, centered around about 1,265. I then add ordinary week-to-week noise inside each scenario and discretize the result into the requested 202-bin array. That leaves me with a median near 1,190 and a mean in the high 1,180s, with most probability mass between roughly 1,130 and 1,260. This is above the deep-crisis 2024 average but still meaningfully below full pre-crisis normalization, which is the balance of evidence from the latest IMF and World Bank material. (datapartnership.org)
IMF PortWatch’s Daily Chokepoints Data defines transit calls as AIS-based ship transits through a chokepoint boundary, counted once even if a transit spans several days, with a 48-hour threshold before the same ship can be counted again. The relevant chokepoints here are Suez Canal (chokepoint1), Bab el-Mandeb Strait (chokepoint4), and Cape of Good Hope (chokepoint7). (portwatch.imf.org)
The latest IMF-derived public readings I could verify were for 2026-04-12. MacroMicro’s IMF series showed 7-day moving-average daily transit calls of 38.57 for Suez, 33.43 for Bab el-Mandeb, and 90.86 for the Cape. Multiplying their sum by 7 gives a current combined pace of about 1,140.02 calls per week, which is already near the low-middle of this market’s range. (en.macromicro.me)
A separate JMIC weekly dashboard based on S&P Global, through the week ending 2026-03-15, showed 247 weekly Suez transits, 153 Bab al-Mandeb transits, and 731 Cape transits for cargo-carrying ships, for a combined 1,131. Although that source is not identical to IMF PortWatch and uses a narrower vessel universe, it independently supports the picture of a combined total clustered in the low 1100s under current disruption conditions. (dbce.org)
For the forward outlook, the key variable is route choice rather than total trade alone: a ship using the Red Sea corridor is counted twice in this market (Bab el-Mandeb plus Suez), while a diverted ship rounding the Cape is counted once. The upside case is therefore a gradual Red Sea reopening. But the evidence still argues against a fast full normalization: the U.S. MARAD advisory on Houthi attacks remains in force until September 22, 2026; Norway’s maritime authority kept the southern Red Sea/Bab el-Mandeb at MARSEC/ISPS level 3 in March 2026; Maersk and Hapag-Lloyd only tested limited Suez returns and Maersk then paused future trans-Suez sailings on March 1; and Good Judgment Open forecasters put a 98% chance on the Suez 7-day average not reaching 60 before May 1, 2026. (maritime.dot.gov)
There is still some upside by late July and early August. Hapag-Lloyd and Maersk had already routed one joint service back through the Red Sea/Suez from mid-February, CMA CGM was still issuing Red Sea/Bab el-Mandeb transit advisories in late February and March, and the IMF’s April 2026 regional outlook used a reference scenario in which war-related disruptions fade by the middle of 2026. I treat that as weak evidence for modest improvement by August, not for full normalization. (hapag-lloyd.com)
My synthesis is a four-scenario mixture: 45% status quo around 1,140, 35% gradual normalization around 1,215, 10% sharp normalization around 1,285, and 10% re-escalation around 1,050. That produces a mean forecast of about 1,171.75, which is my point estimate. In plain language, I expect most probability mass to sit roughly between 1,110 and 1,255, with a meaningful but not dominant left tail below 1,100 if Red Sea security worsens again, and a smaller right tail above 1,300 if carriers return faster than expected. This scenario mix is my inference from the current IMF/JMIC levels and the security and carrier evidence above. (en.macromicro.me)
I interpret the target as the simple sum of IMF PortWatch transit calls for the Suez Canal, the Cape of Good Hope, and the Bab el-Mandeb Strait for Monday, July 27, 2026 through Sunday, August 2, 2026 (UTC).
My first anchor is the pre-crisis level. The World Bank PortWatch methodology page reports reference-period daily averages of 70.87 transit calls for Bab el-Mandeb, 70.12 for Suez, and 46.04 for the Cape of Good Hope. That implies a pre-crisis combined weekly level of about 1,309.2 transit calls. (datapartnership.org)
My second anchor is the depressed-but-not-collapsed current level. A World Bank update published on July 31, 2025 said Suez traffic in the first two weeks of July 2025 averaged 230 ships per week, versus 253 ships per week in January 2025 and more than 500 ships per week in 2023, while Cape traffic remained above historical levels. More recently, IMF-sourced MacroMicro series pages showed latest indexed 7-day moving-average daily readings of 38.57 for Suez, 33.43 for Bab el-Mandeb, and 90.86 for the Cape, which implies a combined weekly run rate of about 1,140.0. (thedocs.worldbank.org)
My third anchor is persistence. On April 29, 2026, the IMF wrote that Bab el-Mandeb transits remained stuck at roughly half their pre-attack level more than two years after the 2023 attacks began. That is a strong signal against assuming a fast snap-back by early August 2026. (imf.org)
Carrier behavior is mixed rather than fully normalized. Maersk announced on January 15, 2026 that the MECL service would return to Trans-Suez routing, but on March 1, 2026 it said future Trans-Suez sailings through the Bab el-Mandeb Strait were being paused because of deteriorating security. Hapag-Lloyd’s May 1, 2026 operational update still says some Asia services are being redirected via alternate routes due to safety concerns in the Red Sea. At the same time, MSC announced a new Europe-Red Sea-Middle East Express on May 2, 2026, which points to some selective re-expansion of Red Sea/Suez usage. In my view, that combination supports modest additional recovery by late July, but not a wholesale return to the old routing equilibrium. (maersk.com)
So I center the forecast only modestly above the current roughly 1,140 weekly run rate. My mean forecast is 1,157.66. I implement that with four scenarios: 57% status quo/slow recovery (mean 1,148), 25% partial recovery (1,205), 15% renewed disruption (1,088), and 3% near-normalization (1,295). Those scenario means are chosen to bracket: (a) little change from current conditions, (b) partial closure of the roughly 169-point gap versus the pre-crisis 1,309 baseline, (c) a renewed security deterioration that pushes more ships back around the Cape, and (d) a low-probability broad return toward pre-crisis routing. The resulting distribution has its mode in the mid-1100s, meaningful downside below 1,100 if security worsens again, and only a thin tail above 1,300 because the IMF and carrier evidence still point to a sticky, only partially healed Red Sea system. (datapartnership.org)
I treat IMF PortWatch as the source of truth. The PortWatch ArcGIS layer confirms the three relevant chokepoints and their IDs: Suez Canal = chokepoint1, Bab el-Mandeb Strait = chokepoint4, and Cape of Good Hope = chokepoint7. The same metadata page shows the chokepoint table was last edited on April 28, 2026, so the dataset is actively maintained and near-current. (worldbank.github.io)
My baseline is the latest available 7-day moving-average transit-call data I could verify for each route. On April 12, 2026, the Suez Canal was at 38.57 daily transit calls, Bab el-Mandeb at 33.43, and the Cape of Good Hope at 90.86. Summed together, that is 162.86 daily calls, or about 1,140.02 transit calls over 7 days. That is the cleanest starting point for a forecast of the July 27-August 2, 2026 week, before adding structural and geopolitical adjustments. (en.macromicro.me)
The main uncertainty is not ordinary week-to-week noise; it is whether Red Sea security improves enough for materially more traffic to return to Suez and Bab el-Mandeb by late July. The evidence so far points to only partial normalization. Hapag-Lloyd and Maersk said in early February 2026 that one shared IMX service would resume transiting the Red Sea and Suez with naval assistance, but Maersk also rerouted ME11/MECL sailings around the Cape on March 1 because of deteriorating security conditions. Separately, the U.S. Maritime Administration’s 2026-006 advisory says Houthi threats to commercial vessels in the Red Sea, Bab el-Mandeb, and Gulf of Aden remain in force until further notice, and the advisory itself is set to expire only on September 22, 2026. BIMCO also reported that in the first week of 2026 Suez traffic was still about 60% below the corresponding 2023 week. Taken together, that argues against assuming a full or near-full recovery by August 2026. (hapag-lloyd.com)
At the same time, I do not expect a collapse in the combined three-route total. On April 9, 2026, IMF Managing Director Kristalina Georgieva said ship passages through Bab el-Mandeb remained about half their 2023 level, which is consistent with a prolonged partial-rerouting equilibrium rather than a sudden normalization. The IMF’s April 2026 World Economic Outlook projects global growth of 3.1% in 2026 under its baseline, implying slower trade growth rather than a major demand surge. A useful seasonality check is the World Bank’s July 31, 2025 note that Suez weekly traffic in the first half of July 2025 (230 ships/week) was below January 2025 (253/week), so late July is not obviously a strong seasonal upside month for this metric. (imf.org)
My inference is that, because these three chokepoints are substitutes, route composition can move a lot while the combined total moves much less than Suez or Bab el-Mandeb individually. So I start from the current combined weekly run rate of about 1,140, add only a small upward drift for possible gradual recovery and ordinary demand variation, and keep a meaningful downside tail for renewed disruption and weaker trade. That leads me to a point estimate of 1,142 transit calls for the week ending August 2, 2026. I represent uncertainty with a three-scenario mixture: 60% status quo/limited normalization (mean 1,140), 25% partial recovery by late July (mean 1,175), and 15% renewed disruption or softer demand (mean 1,095). This puts most mass in the low-1100s to mid-1100s, leaves a meaningful left tail below 1,100, and leaves only a very small probability above 1,300. (en.macromicro.me)
