Brent +2.6% to $112. Then Trump postpones the Iran strike. Now what.

Monday was the cleanest two-leg session of the war. Crude raced higher into the close on a weekend UAE-nuclear drone strike and Trump’s “TIME IS OF THE ESSENCE” framing. Then, four hours after the close, the same president posted that he was holding off on a Tuesday strike at the personal request of Qatar, Saudi Arabia, and the UAE because “serious negotiations are now taking place.” The reversal was immediate: by Tuesday-morning Asian trade Brent was back below $110, WTI July (the new front month) was off 2 percent to $102. The trade is no longer about whether the supply shock continues — it is about how Tehran responds to the carrot of an oil-sanctions waiver Iran says Washington has accepted in the latest draft.

Monday Settle · Brent +2.6% to $112.10 · Then Trump Postpones Tuesday Strike · Mon, May 18, 2026

Start with the settlement-day move. Brent crude July futures rose $2.84 (+2.6 percent) to settle at $112.10 a barrel — the highest closing level since May 5. WTI June futures gained $3.24 (+3.1 percent) to settle at $108.66 — the highest since April 30. June RBOB gasoline pushed to a near-four-year high. The catalysts stacked: a weekend drone strike sparked a fire near the UAE’s only nuclear plant in what authorities called an “unprovoked terrorist attack” (no injuries, no radiation release); Trump posted Monday morning that “for Iran, the clock is ticking, and they better get moving FAST, or there won’t be anything left of them. TIME IS OF THE ESSENCE!”; Axios reported Trump had been weighing renewed military action after Iran’s latest proposal “fell short of expectations.” The Strait of Hormuz remains effectively closed; tanker traffic continues to run at roughly 20-30 vessels per 24 hours against a pre-war norm of approximately 140 per day.

The reversal arrived after the close. Trump posted on Truth Social that he was postponing the planned Tuesday strike on Iran after the leaders of Qatar, Saudi Arabia, and the United Arab Emirates personally requested he “hold off” because “serious negotiations are now taking place.” The post instructed the Pentagon to remain prepared for “a full, large scale assault of Iran, on a moment’s notice, in the event that an acceptable Deal is not reached.” Brent dipped back below $110 in extended trade; by early Tuesday Asian hours Brent July had fallen $3.01 (-2.7 percent) to $109.09 a barrel, WTI June had fallen $1.38 (-1.3 percent) to $107.28, and the more-active WTI July contract had fallen $2.06 (-2 percent) to $102.32. June WTI expires at Tuesday’s close. Iran’s revised proposal — relayed via Pakistani mediators — reportedly includes a long-term nuclear freeze (not full dismantling), transfer of enriched uranium to Russia rather than the US, dropped demands for direct US financial compensation in exchange for international guarantees, and a gradual peace arrangement. Iran’s Tasnim news agency separately reported the latest US text accepts a temporary waiver on Iran oil sanctions during the talks period — an explicit supply carrot that has not been publicly confirmed by US officials.

The macro context is hardening even as crude reverses. The International Energy Agency warned Monday that global oil inventories are declining rapidly. At the G7 finance-ministers meeting in Paris, Eurogroup President Kyriakos Pierrakakis said opening the Strait of Hormuz and bringing the conflict to a lasting end are “of the utmost importance” in mitigating the impact on the global economy. The US 10-year Treasury yield touched 4.63 percent intraday Monday on energy-inflation pricing. The 30-year hovered near 5.13 percent, a level last seen in 2007. Chevron led S&P 500 winners at +2.57 percent — the cleanest equity-tape confirmation that the war-premium repricing has institutional support. ING analysts and Reuters mediation contacts both note the Pakistan-mediated parties “don’t have much time to narrow their differences.” The trade now hinges on a single binary outcome inside roughly 7-14 days: either Iran accepts a framework that includes a Hormuz-reopening commitment and a sanctions waiver lights up new supply, or the Pakistan track collapses and Trump executes on the “moment’s notice” clause. Position for both.

Four other Monday signals all pointing at the same binary.

Drone strike sparks fire near UAE’s only nuclear plant. A weekend drone strike sparked a fire near the Barakah nuclear power plant on the UAE’s Persian Gulf coast — the country’s only nuclear facility — in what UAE authorities called an “unprovoked terrorist attack,” per the Associated Press. There were no reported injuries and no radiological release. The attack was the catalyst that priced into Monday’s opening tape: Brent gapped higher at the Asian-session open, the rally extended through US trading hours on Trump’s morning “TIME IS OF THE ESSENCE!” post, and settled +2.6 percent on the day at $112.10. Other Persian Gulf energy infrastructure also came under attack over the weekend. The strike forced the diplomatic clock forward by 48-72 hours; the Trump postponement that followed reset it.

Iran’s revised terms via Pakistan: nuclear freeze, uranium to Russia, sanctions-waiver carrot. Pakistani mediators delivered Iran’s revised proposal to Washington Monday. Per reporting from CBS News, Reuters, and Iran’s semi-official Tasnim agency, Tehran’s new terms include a long-term nuclear freeze (not full dismantling), transfer of enriched uranium to Russia rather than the US, dropped demands for direct US financial compensation in exchange for international guarantees, and a gradual peace arrangement with the US and Israel. Tasnim separately reported the latest US text accepts a temporary waiver on Iran oil sanctions during the talks period — not publicly confirmed by US officials. A Pakistani source warned Reuters the parties “don’t have much time to narrow their differences.” If the waiver framework lights up, the back end of the Brent curve fades fast.

IEA: global inventories declining rapidly. Eurogroup at G7: Hormuz reopening ‘of utmost importance.’ The International Energy Agency warned Monday that global oil inventories are declining rapidly on sustained Hormuz disruption and resilient Q2 demand. At the G7 finance-ministers meeting in Paris the same day, Eurogroup President Kyriakos Pierrakakis — the Greek finance minister and current Eurogroup chair — said in a formal statement that “opening the Strait of Hormuz and bringing the conflict to a lasting end are of the utmost importance” for the global economy. The framing matters: the IEA flag plus the Eurogroup G7 statement is the cleanest institutional alarm of the war so far and the strongest pressure on Washington to accept a framework that re-opens supply.

WTI June expires Tuesday. July is the new front month — at $102. The mechanical roll matters here. June WTI (CLM26) settled Monday at $108.66 and expires at Tuesday’s close. The more-active July contract (CLN26) was already trading roughly $6 lower than June at the Monday settle — and fell $2.06 (-2 percent) to $102.32 in early Tuesday Asian trade on the Trump postponement. That is the curve speaking: the market sees the maximum-disruption window as already in the rear-view, with structural backwardation pricing the assumption that any Iran framework (or even a credible postponement) re-opens Hormuz on a 30-60 day timeline. Hedgers operating on the front month: do not roll passively. The shape of the curve from here is the trade.
