TL;DR

President Trump announced at approximately 3:43 p.m. ET on Monday that he is calling off a planned US military strike on Iran that had been scheduled for Tuesday. The decision came after the leaders of Qatar, Saudi Arabia, and the United Arab Emirates asked him to pause and allow for deal negotiations. Oil prices closed sharply higher before the post landed, and remain elevated in extended trading. US stocks ended lower on the day, while the dollar and treasury yields stayed under pressure from ongoing Hormuz supply concerns.

What Happened: Trump Iran Attack Called Off

In a Truth Social post published at roughly 3:43 p.m. ET, Trump announced he had informed Defense Secretary Pete Hegseth and Joint Chiefs Chairman General Daniel Caine that "we will NOT be doing the scheduled attack of Iran tomorrow." The president said the Qatar Emir Tamim bin Hamad Al Thani, Saudi Crown Prince Mohammed bin Salman, and UAE President Mohammed bin Zayed Al Nahyan had requested the postponement, citing ongoing negotiations they believe could produce an acceptable deal.

There had been no prior public confirmation that a Tuesday strike was on the calendar. Earlier Monday, Trump told the New York Post that Iran "knows what's going to be happening soon," and a report from Axios revealed that the US had rejected Iran's latest diplomatic proposal as insufficient. Iranian Foreign Ministry officials said talks were proceeding through Pakistan, though they denied that any direct negotiations with Washington were taking place.

The decision to pause is explicitly conditional. Trump said the military should remain ready "to go forward with a full, large scale assault of Iran, on a moment's notice, in the event that an acceptable Deal is not reached." His post closed with a demand for no Iranian nuclear weapons as a non-negotiable condition of any agreement.

Why Markets Moved

Oil markets were already highly reactive before the Truth Social post. The rejection of Iran's proposal had driven Brent crude above $110 earlier in the session. By the close, Brent futures settled up approximately 2% at $112.10 per barrel, and West Texas Intermediate (WTI -- the US benchmark) settled about 3% higher at $108.66. In extended trading, Brent dipped back below $110 after the postponement news, but did not give back the day's full gains.

The reluctance to sell reflects the underlying supply picture. The Strait of Hormuz -- the narrow waterway between Iran and Oman through which roughly 20% of the world's crude oil and liquefied natural gas (LNG) flowed before the war -- remains mostly closed due to dueling blockades. Oil inventories globally have been drawn down to record-low levels, leaving markets with limited buffer against any further supply disruption. US natural gas futures also rose above $3 per million BTUs on Monday for the first time since March, adding to the energy-price pressure.

US equities stayed in the red throughout the session. The S&P 500 closed down roughly 0.3%, the Dow Jones Industrial Average fell about 0.3%, and the Nasdaq Composite edged lower by 0.1%. Bitcoin had sold off sharply earlier in the day on the same Iran war escalation fears, falling to near $76,500, though price action after the postponement announcement was still settling at press time.

Implications for Traders

Oil and Energy Futures

The postponement reduces imminent strike risk but does not remove the war premium from crude pricing. The Hormuz closure and record-low inventories mean any breakdown in talks could send Brent sharply higher. Traders with long energy exposure may look to hold through the negotiation window, while those with short positions face an asymmetric risk profile given how quickly the situation can shift. Natural gas above $3 signals that the LNG supply disruption through Hormuz is also being repriced.

US Stocks and Index Futures

Equities remain caught between relief at a one-day reprieve and anxiety about whether a deal actually materializes. Energy stocks and defense names have been primary beneficiaries of the war environment; a genuine ceasefire extension would weigh on those sectors while potentially lifting consumer-facing names and transports that have been depressed by high fuel costs. S&P 500 futures will likely be sensitive to any overnight diplomatic headlines from the region.

Crypto Markets

Bitcoin's intraday drop to near $76,500 reflected the same risk-off wave that pressured equities. Crypto tends to recover quickly on de-escalation signals, so the postponement announcement may provide short-term support. However, with no deal yet confirmed and Trump's military-ready standby order still in effect, a sustained recovery will likely require more concrete diplomatic progress.

Potential positives vs negatives

Positives from the postponement

  • Removes the immediate binary risk of a full military escalation resuming Tuesday, reducing the probability of a fast price spike in crude and a sharp equity sell-off in the near term.
  • Gulf state engagement from Saudi Arabia, UAE, and Qatar signals that regional heavyweights believe a workable deal is achievable, which carries diplomatic credibility beyond Trump's own statements.
  • A successful deal framework, if reached, could eventually reopen Hormuz and ease the global supply crunch that is driving energy inflation across multiple economies.

Negatives and ongoing risks

  • The ceasefire has already been called "life support" by Trump himself, and Iran has publicly denied the scope of any ongoing talks, creating a credibility gap that could unravel quickly.
  • Trump's standby order for an assault "on a moment's notice" means market volatility can restart without warning if negotiations collapse.
  • Oil inventories are already at record lows. Even a brief resumption of hostilities or a new Hormuz incident could push Brent well above current levels.
  • Long stretches of diplomatic back-and-forth typically hurt planning for oil-dependent industries and keep equity risk premiums elevated.

What Could Happen from Here

Base case (moderate probability)

Negotiations between the US, Iran, and Gulf intermediaries continue over the next few days. No deal is finalized quickly, but the absence of immediate military action gives talks time to produce a framework. Oil stays in the $105 to $115 range on the Hormuz uncertainty premium. US stocks remain rangebound, with any dip in Iranian escalation risk briefly lifting the index. A ceasefire extension is eventually formalized but the Hormuz reopening timeline stays unclear. This scenario is confirmed by: sustained diplomatic statements from Qatar and UAE that talks are progressing; Iranian confirmation of bilateral contact with US representatives. It is invalidated by: a new Iranian military action against US or Gulf assets, or Trump announcing a return to strike planning on Truth Social.

Upside case

Iran accepts a deal outline within 72 hours that includes Hormuz reopening and a verifiable pause on its nuclear program. Brent falls sharply toward the $85 to $95 range as a supply-recovery trade. US equities rally, led by transports and consumer discretionary names. Bitcoin and risk assets recover as the macro overhang from the war lifts. Confirmed by: a joint statement from Qatar or UAE that a framework agreement has been reached; US Treasury removing Iran port blockade in a phased approach.

Downside case

Iran's domestic political situation blocks any deal, or a new incident in the strait reignites hostilities before negotiations conclude. Trump resumes strike planning, oil moves above $120, US equity futures sell off 1-2% overnight, and risk assets reprice sharply lower. Confirmed by: an Axios or Reuters report that the US has returned to active targeting planning; a new ship seizure or drone attack in the Hormuz corridor. Invalidated by: continued quiet in the strait for 48 or more hours and ongoing diplomatic engagement.

What to Watch Next (Next 24 Hours)

  • Hormuz corridor incidents: Any new tanker seizure, drone attack, or blockade action will be the fastest trigger for an oil spike and US equity risk-off move.
  • Iranian foreign ministry statements: Watch for whether Tehran formally acknowledges the US has called off Tuesday's action and what condition it attaches to any response.
  • Gulf intermediary signals: Statements from Qatar's Emir or Saudi Crown Prince MBS on the state of negotiations will be a leading indicator of whether talks are substantive.
  • WTI and Brent overnight session: If crude sustains above $110 in Asian hours, the market is still not pricing in a deal. A move below $105 would signal meaningful confidence in a near-term framework.
  • US S&P 500 futures: After-hours price action will reflect how traders are interpreting the net risk of the postponement versus the absence of a confirmed deal.
  • Fed Chair transition: Kevin Warsh is scheduled to take over as Federal Reserve Chair on Friday. Markets are also watching how a new chair will frame monetary policy against a commodity-price shock backdrop.

FAQ

Why did Trump call off the Iran attack?
Trump said the leaders of Qatar, Saudi Arabia, and the UAE asked him to hold off, citing ongoing negotiations they believe will produce an acceptable deal. He emphasized the military remains ready to strike on short notice if talks fail.

What does this mean for oil prices?
In the near term, it reduces the probability of an immediate escalation, which caused Brent to pull back slightly from its $112 close in extended trading. However, oil remains elevated because the Hormuz Strait is still largely closed and global inventories are at record lows. A genuine deal would need to reopen the strait to bring prices down substantially.
