The question asks whether the broad baseline Section 122 global import surcharge will be formally raised above 10% by a qualifying presidential action between now and Aug 12, 2026. Forecasters agree the resolution hinges on a formal presidential directive (not rhetoric) and on the statutory clock: the current 10% proclamation runs through 12:01 a.m. EDT on July 24, so any realistic increase is concentrated before that date, with a much smaller post‑July‑24 tail only if Congress extends or revives the authority. Although administration officials signaled intent to go to 15% in February–March, no formal proclamation or Federal Register action has appeared in four months, and teams noted this unformalized delay as important. Litigation over the existing 10% surcharge and the administration’s parallel pursuit of Section 301/232 tools both reduce the likelihood of using Section 122 to escalate tariffs. One forecasting team explicitly quantified the view at about a 24% chance of a qualifying increase by Aug 12, while others similarly place most probability mass on no qualifying action, concentrated risk in early–late July, and only a small chance after July 24 absent congressional action. Watchlist priorities are any White House proclamation or Federal Register language amending Proclamation 11012 or invoking Section 122.
Forecast: Probability distribution:
Key drivers are (i) whether the administration chooses to formally amend/reissue a Section 122 action to lift the baseline surcharge above 10% (most plausibly to the 15% statutory ceiling), and (ii) the tight timing around the widely-cited ~150-day sunset of the February 2026 Section 122 surcharge around July 24, 2026, plus ongoing litigation/uncertainty and an apparent policy pivot toward other tariff authorities (which would not qualify).
Across analysts, the main disagreement is probability of any qualifying in-window action: estimates range from very low (~5–10%) to modest (~20–30%). I discount the most extreme “near-impossible” framing because a new or amending proclamation explicitly invoking Section 122 is not logically barred during the window, but I still put most mass in the open-after tail because (a) there has been ample time to implement a 15% increase and it has not happened, (b) the approaching sunset reduces the incentive to revise the rate late, and (c) legal/political frictions make an escalation less attractive. Net: I center the probability of a qualifying >10% Section 122 increase by 2026-08-12 at ~15% (so 85% resolves as >2026-08-12), with the “if it happens” mass concentrated in mid-to-late July ahead of the likely sunset.
An amateur forecast is likely to anchor on headline-level statements about “raising to 15%” and place too much probability inside the window, or to mistakenly treat other authorities (e.g., Section 301/232) as qualifying. This forecast explicitly accounts for (1) the need for a formal Section 122 directive, (2) the late-July timing pressure from the 150-day structure, and (3) the substantial chance of no qualifying action at all in-window (expressed correctly via percentiles strictly past the upper bound rather than piling mass at the bound). Confidence in improvement is moderate: the main remaining uncertainty is political volatility and the possibility of an unexpected last-minute proclamation.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the reasoning centers on a few common factors:
Overall, the shared logic is: the expiration date creates a narrow opportunity window, but legal/political constraints make an above-10% Section 122 tariff increase by the cutoff unlikely, with any plausible near-term action concentrated just before expiration.
— Iteration 2 —
The forecasts center on a few shared considerations:
The main timing anchor is the July 24, 2026 expiration of the current 10% Section 122 tariff.
If an action increasing the rate above 10% happens under Section 122, it is most likely to be announced near that expiration date, with a concentration in mid-to-late July 2026.
There is stated intent, but little visible execution momentum.
The administration has reportedly signaled a desire to raise the rate to 15%, yet there has been no formal implementation action for months and little sign of operational preparation. That weakens confidence in an imminent move.
Legal and procedural risk is a major drag on near-term probability.
The forecasts emphasize litigation risk, including a recent Court of International Trade ruling, which may make a Section 122-based increase vulnerable or unattractive.
A key alternative is that the administration bypasses Section 122 entirely.
Several rationales note that policymakers could switch to other tariff authorities such as Section 301. If that happens, then the specific event being forecast—an executive action under Section 122 raising the baseline global rate above 10%—may never occur, or occur much later than the near-term window.
The collective reasoning suggests that the event, if it happens at all, is most likely tied to the July 24, 2026 expiration point, but legal vulnerability, lack of implementation signals, and the option to use other authorities create a meaningful chance that the Section 122 increase does not materialize in the near term and may never occur under that statute.
— Iteration 3 — Across the forecasts, the core view is that the statutory deadline on July 24, 2026 is the main focal point for any Section 122 action, because that is when the 150-day period expires. If the president does act, the most likely timing is late July, potentially as a proclamation raising the baseline global tariff rate to 15%.
The main reasoning patterns are:
Consensus: near-term risk concentrates around mid-to-late July, but the overall probability remains low.
Disagreement: the forecasts vary on how much near-term probability to assign, but they agree on the broader conclusion that most probability mass lies after Aug. 12 or in a no-action scenario.
The rationales overwhelmingly agree that the President is highly unlikely to issue an executive action increasing the Section 122 baseline global tariff rate before the resolution window closes. This consensus is driven by strict statutory deadlines, severe legal vulnerabilities, and a deliberate shift in the administration’s trade strategy.
Statutory Deadlines and Legal Vulnerabilities Under Section 122 of the Trade Act of 1974, temporary import surcharges are strictly capped at 150 days unless extended by an Act of Congress. Because the initial 10% tariff took effect on February 24, 2026, the underlying authority faces a hard expiration date of July 24, 2026, with no bipartisan momentum for a legislative extension. Furthermore, the U.S. Court of International Trade (CIT) ruled the baseline tariff unlawful in May 2026. Although the policy survives temporarily via an appellate stay, forecasters note that formally escalating the tariff rate while the foundational authority is structurally invalidated would be deeply perilous, likely inviting immediate injunctions and exposing the government to massive refund liabilities.
The Strategic Pivot to Section 301 Instead of fighting to extend or escalate the legally precarious Section 122 tariffs, the administration is utilizing them merely as a temporary bridge. The U.S. Trade Representative (USTR) has proactively pivoted to fast-tracking structural replacement tariffs under Section 301 (and Section 232). The administration’s clear strategy is to finalize these alternative measures so they can seamlessly take effect right as the Section 122 authority lapses in late July. Crucially, the question’s resolution criteria explicitly exclude tariffs enacted under alternative authorities like Section 301.
Tail Risk The only recognized scenario for a rate increase is the slight tail risk of an erratic, last-minute hike to the 15% statutory maximum. Forecasters note that if the President were to act against legal consensus, it would happen just prior to the July 24 expiration as a brinkmanship maneuver to exert leverage over foreign trading partners. Otherwise, the administration is expected to let the Section 122 clock simply run out.

The research finds that no increase above the 10% global tariff under Section 122 has occurred or been announced. The Trump administration imposed a 10% Section 122 tariff on February 24, 2026, effective for 150 days (set to expire July 24, 2026 unless Congress extends it). The U.S. Court of Appeals for the Federal Circuit ruled in mid-June 2026 that the government is likely to succeed on the merits and may continue collecting the 10% tariff while litigation proceeds, but litigation (including a challenge by the Liberty Justice Center in Burlap and Barrel, Inc. v. Trump) and legal constraints on Section 122 remain important considerations. Section 122 is uniform (cannot target individual countries) and allows up to 15% but requires Congressional approval beyond 150 days; historically Section 122 had not been used to justify import taxes prior to February 2026.
The research reports the administration appears to prefer Section 301 investigations (which can produce country-specific tariffs) over increasing Section 122 to 15%. USTR began Section 301 work in March 2026 with preliminary proposals (including a proposed additional 12.5% on imports from 54 countries), hearings starting July 7, and final determinations expected in July. Key timeline pressures are the July 7 Section 301 hearings and the July 24 Section 122 expiration; no active prediction markets specifically cover a Section 122 increase; and despite high-profile threats (e.g., a June 26–27 threat of 100% tariffs on countries with digital services taxes), legal caps and timing make a Section 122 increase above 10% during the question window assessed as unlikely. The research’s qualitative probability estimate for an increase under Section 122 above 10% before August 12, 2026, is roughly 10–20%, and the most likely outcomes are either expiration at 10% on July 24 or congressional extension at 10% with Section 301 tariffs layered separately.
Sources used (as cited in the research): Metaculus (question), U.S. Court of Appeals for the Federal Circuit (June 11–12, 2026 ruling), Liberty Justice Center, Burlap and Barrel, Inc. v. Trump, statements by Treasury Secretary Scott Bessent (June 25, 2026), U.S. Trade Representative (Section 301 investigations), Polymarket, Kalshi, various news reports of Trump’s June 26–27 tariff threats, and multiple news/legal outlets cited in the numbered references [1]–[29] in the original research. The submitted research did not include verbatim URLs for those numbered references.
Based on my comprehensive research, here’s what you need to know about this Metaculus question on Section 122 tariff increases:
No evidence of any increase above 10% has occurred or been announced. The Trump administration imposed a 10% global tariff under Section 122 of the Trade Act of 1974 on February 24, 2026, effective for 150 days [1][2][3][4][5]. This means the tariffs are set to expire on July 24, 2026 - just 25 days from now - unless Congress extends them.
On June 11-12, 2026, the U.S. Court of Appeals for the Federal Circuit ruled that the government is “likely to succeed on the merits” and can continue collecting the 10% tariff while legal challenges proceed [1][2][3][4]. However, the underlying Section 122 tariffs remain contested, with the Liberty Justice Center’s lawsuit (Burlap and Barrel, Inc. v. Trump) challenging whether Section 122 permits broad worldwide tariffs based on trade deficits [22].
Critically, the administration appears focused on using Section 301 investigations as their primary tool going forward, rather than increasing Section 122 tariffs to 15%. Treasury Secretary Scott Bessent stated on June 25 that if Section 301 studies are successful, “tariff rates are going to go back to exactly where they were” - referring to the previous country-specific reciprocal tariffs [11][12].
The U.S. Trade Representative initiated Section 301 investigations in March 2026, with preliminary findings proposing an additional 12.5% tariff on 54 countries including India. Public hearings begin July 7, 2026, with final determinations expected in July [11][15][16].
Historical precedent for Section 122: According to multiple sources, Section 122 had never been used to justify import taxes before Trump’s February 2026 action [1][3][4][21][25]. This means:
Trump administration tariff pattern:
Legal viability: Section 122 requires uniform application and cannot target individual countries [21][25]. The administration’s stated goal is to restore differentiated, country-specific tariffs, which Section 122 cannot provide. Section 301 better serves this objective.
I found no active prediction markets specifically covering whether Trump will increase Section 122 tariffs above 10%. This appears to be too specific an administrative action for current prediction market coverage on platforms like Polymarket, Kalshi, or Metaculus itself.
The most significant recent development is Trump’s June 26-27 threat to impose 100% tariffs on countries implementing digital services taxes [10][13][26][27][28][29]. However, multiple analysts note this threat faces severe legal obstacles since Section 122 expires July 24 and caps at 15%, while Section 301 requires a lengthy investigative process [10][13].
The balance of evidence suggests it is unlikely Trump will increase Section 122 tariffs above 10% during the question period because:
The most likely scenarios are: (1) Section 122 expires July 24 without increase, or (2) it’s extended by Congress at 10%, with Section 301 tariffs layered on top separately. An increase to 15% specifically under Section 122 would be administratively unusual given the alternative paths available.
Probability assessment (qualitative): Based on the evidence, I would estimate a low probability (perhaps 10-20%) that Trump signs an executive action increasing Section 122 above 10% before August 12, 2026. The question would most likely resolve as “>2026-08-12T12:00:00+00:00”.
Conditioning on the question not being annulled, my central forecast is that no qualifying action occurs by the cutoff, with roughly 12% probability of a qualifying Section 122 increase within the window.
(a) The outcome will be known no later than 2026-08-12T12:00:00Z, which is about 44 days from 2026-06-29; exactly 44 days and 30 minutes from the trigger-window start at 2026-06-29T11:30:00Z.
(b) Outside view: the narrow reference class is almost empty. Section 122 had not previously been used to justify import taxes before this 2026 action, and there are no historical cases of midstream Section 122 rate increases. The statute allows up to 15% for up to 150 days, but the official proclamation imposed 10% effective 2026-02-24 and running through 2026-07-24 unless modified, terminated, or extended by Congress. (federalregister.gov)
(c) Inside view: there was an earlier pro-increase signal—Bessent said in 2026-03 that a move from 10% to 15% was likely “sometime this week”—but that was not converted into an official action, which is strong negative evidence now that the surcharge is close to expiration. The current policy track appears to be Section 301 replacement tariffs: USTR has proposed 10% or 12.5% additional duties in Section 301 investigations, with comments due 2026-07-06 and hearings on 2026-07-07; Bessent later said rates would return to prior levels if Section 301 studies succeed. (newsmax.com)
(d) Outcome if nothing changed: >2026-08-12T12:00:00Z.
(e) Outcome if the current trend continued: the Section 122 surcharge expires around 2026-07-24 at 10%, while the administration substitutes Section 301 and Section 232 tools; the question resolves >2026-08-12T12:00:00Z. Trade-law commentary has also framed Section 301 as the administration’s “plan C” rather than a Section 122 rate increase. (axios.com)
(f) Expectations of experts and markets: I see no dedicated market signal for this exact trigger. The expert/reporting signal is qualitatively low-probability: tariffs remain central to policy, but the expected implementation route is Section 301, not increasing the temporary Section 122 baseline.
(g) Unexpected low outcome: a sudden dollar/current-account scare, failed trade talks, or political desire for a dramatic pre-expiration move leads to a quick proclamation raising the baseline to 15% in early 2026-07.
(h) Unexpected high outcome: Section 301 implementation slips, Congress signals or passes a short extension, and the White House uses a late-window Section 122 modification as leverage close to 2026-08-12. More likely, however, “high” simply means no qualifying action by the cutoff.
Rationale: I anchor on the near-zero Section 122 historical base rate and the short remaining lifetime of the existing surcharge. Trump’s general willingness to use tariffs and the earlier 2026-03 15% signal keep the probability from being tiny, but the failure to act when the tariff had far more remaining useful life is a major downward update. The ongoing litigation, the statutory 150-day limit, and the active Section 301 replacement path push me to about 12% for a qualifying action by 2026-08-12T12:00:00Z, with most of that conditional probability concentrated before or around 2026-07-24.
For percentiles above 2026-08-12, the exact later dates are placeholders encoding the “no qualifying action by cutoff” outcome; what matters is that they are above the cutoff.

(a) Time left: About 44 days remain until the question is known, at 2026-08-12T12:00:00Z, conditional on the question not being annulled.
(b) Outside view: The narrow reference class is essentially empty: Section 122 had reportedly never before been used to justify import taxes, and there are no historical examples of a Section 122 global surcharge being increased mid-period. The statute/proclamation structure allows up to 15% for up to 150 days unless Congress extends it, but the February proclamation set the rate at 10% and the period through 2026-07-24. (apnews.com)
(c) Inside view: Upward evidence is that Trump publicly said after the February action that he wanted the rate raised to 15%, and Navarro later said the increase was still “in process.” Downward evidence is stronger now: no formal order has appeared after months, the White House tariff-action list shows later tariff actions under other authorities but no Section 122 rate increase, and the administration’s active replacement path appears to be Section 301, where USTR has proposed 10%/12.5% duties with comments due 2026-07-06 and hearings on 2026-07-07. (bloomberg.com)
(d) Outcome if nothing changed: No qualifying increase occurs by 2026-08-12T12:00:00Z.
(e) Outcome if the current trend continued: Section 301 processes and other tariff authorities replace the Section 122 stopgap; the 10% Section 122 surcharge expires or is left unchanged, so the resolution is after 2026-08-12T12:00:00Z.
(f) Expectations of experts and markets: I found no market with a directly usable price. Expert/reporting signals look “low but not zero”: trade coverage notes the 15% idea and the legal authority, while current administration comments emphasize Section 301 as the route back to previous tariff levels. Bessent’s recent comment that tariff rates would go back “exactly where they were” after Section 301 studies points away from a Section 122 increase. (ndtvprofit.com)
(g) Unexpected low-date scenario: A sudden political or trade shock—e.g. retaliation over digital taxes, weak dollar/current-account headlines, or a desire to maximize leverage before the 2026-07-24 expiration—leads Trump to sign a quick proclamation in early July raising the Section 122 rate to 15%.
(h) Unexpected high-date scenario: The administration waits for Section 301, courts, or Congress; no extension or modification is ready before 2026-07-24, and any Section 122 increase is abandoned or comes too late for this question.
Rationale: I anchor on the near-zero specific historical base rate for Section 122 increases, then move upward because this administration has already used novel tariff authorities quickly and Trump explicitly floated the 15% ceiling. I move back down because the February/March promises have gone stale, the tariff has only weeks left, legal and trade-agreement costs remain real, and current official machinery is pointed at Section 301 rather than Section 122. My implied probability of a qualifying action by the deadline is roughly 17%, with most of that mass concentrated before the 2026-07-24 expiration and a small residual chance after that if Congress or a late official publication changes the picture. Dates after 2026-08-12 represent the “no qualifying action by deadline” bucket.

Model’s Answer: This is effectively a binary event with timing attached. The true support is any calendar day from 2026-06-29 through 2026-08-12, plus a large post-cutoff “no qualifying action” bucket. There is no fixed reporting cadence here: the President can sign or issue a qualifying directive on any day, and publication can also occur on any day, though weekdays are more common. Because the earliest trigger counts, and because a later-revealed signature date can control, I concentrate the in-window mass on plausible White House action days rather than on Federal Register schedules.
My baseline is that no qualifying action happens. The most recent and most authoritative material all points the same way: the only formal Section 122 global baseline action is still the February proclamation at 10%, it is under legal attack after the CIT ruling, and it is set to expire on 2026-07-24. Those facts matter a lot. If the administration wanted to raise the Section 122 baseline above 10%, the natural time would be before or right around that expiry, not deep into August. The legal cloud also makes this specific tool less attractive relative to other tariff authorities.
I still keep a meaningful low-teens chance on an in-window increase because this administration has shown willingness to move abruptly on trade, some reporting indicated a contemplated move to 15%, and a formal increase would be operationally simple if the White House decided it wanted a tougher headline before the sunset. Most of that chance belongs to mid-to-late July, especially the business days leading into 2026-07-24. I leave only a very small residual tail after 2026-07-24 because a post-expiry Section 122 move seems much less likely and somewhat ambiguous under the resolution wording.
The assumptions doing most of the work are that no already-decided 15% Section 122 directive is waiting to be released, that the litigation and 150-day sunset really do deter modifying this exact measure, and that any tariff escalation is more likely to use other authorities than Section 122. If those assumptions fail, the resolution date likely jumps into early or mid-July. If they hold, the question almost certainly resolves after the cutoff. My bottom line is roughly an 86% chance of no qualifying action by 2026-08-12T12:00:00Z, with about 14% total on a qualifying in-window increase, overwhelmingly before 2026-07-24.

Statutory limits cap a unilateral Section 122 surcharge at 15% and timebox it to 150 days unless Congress acts.
The February proclamation fixed a 10% baseline and remains effective through 12:01 a.m. EDT on July 24, 2026 unless formally modified.
Early public signaling increased political appetite for the 15% ceiling.
Legal rulings and operational guidance have anchored collection and favored the published 10% in practice.
USTR’s Section 301 timetable (comments due July 6, hearings July 7) presents coordination points where a rapid Section 122 hike could be attached.
The immediate pre‑expiration window, roughly July 20–24, is the most plausible last‑minute inflection before the proclamation lapses.
Key uncertainties are White House willingness to court additional litigation, Congressional choices about extension or restraint, and whether Section 301 measures render a Section 122 increase unnecessary.
Outcome sensitivity concentrates on undisclosed internal decisions, the speed and direction of litigation, and any near‑term political signal that compresses or dissipates the July window.
On what date will the POTUS first sign, issue, or officially publish an executive action increasing the baseline global tariff rate imposed under Section 122 of the Trade Act of 1974 above 10%?
Key figures
Historical context
The primary historical precedent for Section 122 is the 1971 “Nixon Shock,” where a 10% import surcharge was imposed to address gold outflows and trade deficits. This event led to the formal codification of Section 122 in the Trade Act of 1974, which established the 150-day time limit and 15% rate cap. In the current 2025-2026 cycle, the administration initially attempted to use the International Emergency Economic Powers Act (IEEPA) for universal tariffs, but this was struck down by the Supreme Court in February 2026 (Learning Resources, Inc. v. Trump). The subsequent invocation of Section 122 on 20th February 2026 was a rapid “bridge” move to maintain tariff levels while navigating the new legal constraints imposed by the judiciary.

Detailed reasoning
My analysis of the potential for a baseline global tariff increase under Section 122 of the Trade Act of 1974 is centered on the fast-approaching statutory deadline of 24th July 2026. The current 10% surcharge was implemented via Proclamation 11012 on 20th February 2026 and became effective on 24th February 2026. Under the law, these actions are limited to a 150-day duration unless extended by Congress. As of late June 2026, no such extension has occurred, and official rhetoric from the Treasury and USTR suggests that the administration intends to let these duties “roll off” or expire.
The reasoning for the predicted date of 19th July 2026—just five days before the scheduled expiration—is based on the “eleventh-hour” pattern often seen in executive trade actions. If the administration intends to use the statutory maximum of 15% permitted under Section 122, it would likely do so in the final week of the current term to maximize negotiating leverage or to provide a “bridge” if alternative Section 301 investigations face procedural delays. I have weighted recent statements from Treasury Secretary Scott Bessent and USTR Jamieson Greer heavily; they indicate a strategic pivot toward Section 301 (focused on forced labor and overcapacity) and Section 232 (national security) as more durable, long-term legal foundations for tariffs.
Furthermore, legal headwinds play a significant role. The U.S. Court of International Trade (CIT) ruled the current 10% tariffs unlawful on 7th May 2026. While the U.S. Court of Appeals for the Federal Circuit issued a stay on 11th June 2026 allowing continued collection, the administration may be hesitant to escalate the rate to 15% while the underlying legal justification—specifically the existence of a “fundamental international payments problem”—is being actively litigated.
Ultimately, the forecast reflects a low total probability (approximately 13-15%) that the event occurs at all. If it does happen, it is almost certain to occur within the remaining days of the current Section 122 window. After 24th July 2026, the probability of a Section 122 increase drops precipitously as the authority lapses and the policy focus shifts entirely to other trade statutes. Therefore, my median prediction reflects the most likely point within that small, high-risk window.
