Trump Postpones Iran Strike After Gulf Pressure, Oil Retreats From $112

President Donald Trump postponed a military strike on Iran originally scheduled for Tuesday, 19 May, after requests from Gulf allies, marking the sharpest tactical retreat in a three-month conflict that has roiled energy markets and tested U.S. deterrence credibility.

The decision came late Monday following interventions by leaders from Qatar, Saudi Arabia, and the UAE, according to PBS News. Trump described the planned operation as “a very major attack” but said he would defer it “for a little while, hopefully, maybe forever” to allow negotiations. Oil futures immediately retreated, with Brent falling from $112.10 to below $110 in extended trading and WTI June contracts shedding more than $2 to close at $107.25, per CNBC.

The postponement represents the latest reversal in a conflict pattern defined by threatened escalation followed by tactical withdrawal. Trump has now set and abandoned multiple military deadlines since the war began 28 February with U.S.-Israeli airstrikes. The strategy echoes his June 2019 cancellation of retaliatory strikes on Iran and the January 2020 Soleimani assassination — moments when sudden shifts in White House calculus left allies and adversaries recalibrating.

Gulf States Drive Diplomacy

Trump said the Gulf leaders requested a two-to-three-day delay to pursue negotiations centred on reopening the Strait of Hormuz and Iran’s nuclear programme, according to MS NOW. The strait, through which 20% of global oil flows, has been partially closed since March when Iran imposed shipping restrictions following initial U.S. strikes. Turkey’s foreign minister confirmed that much of Iran’s enriched uranium remains buried under collapsed tunnels following attacks in June, complicating verification of any nuclear deal.

For Saudi Arabia and the UAE, the calculus is existential. Both nations depend on Hormuz for crude exports and fear that prolonged conflict destabilises shipping lanes, threatens regional oil infrastructure, and invites Iranian retaliation against Gulf facilities. Qatar, which shares the world’s largest natural gas field with Iran, has particular incentive to broker de-escalation.

Trump maintained that he has instructed U.S. military forces “to be prepared 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.” The language preserves optionality but signals deteriorating leverage: the president is now responding to allied timelines rather than setting them.

War Powers Standoff Intensifies

The postponement arrives as constitutional tensions over war authority reach a breaking point. Defense Secretary Pete Hegseth testified 12 May that Trump retains unilateral authority to resume strikes under Article 2 of the Constitution, dismissing the need for congressional approval even after the 60-day War Powers Resolution deadline expired 1 May, according to CNBC.

Democratic lawmakers, joined by Republican senators Lisa Murkowski, Susan Collins, and Rand Paul, advanced a war powers resolution 18 May demanding formal authorisation for continued hostilities, per The Hill. The bipartisan coalition argues Trump’s declaration that hostilities “terminated” on 1 May was a procedural manoeuvre to evade oversight, not a reflection of military reality.

The standoff matters beyond constitutional procedure. If Trump resumes strikes without authorisation, he risks fracturing Republican support in Congress and undermining the legal basis for sustained military operations. If he seeks approval, he faces demands for constraints on scope, duration, and objectives that could limit operational flexibility.

Defense Stocks Underperform Despite War

Contrary to expectations, defense contractors have underperformed broader equity markets since hostilities began. The iShares U.S. Aerospace & Defense ETF declined 12% from 1 March through late April, while the S&P 500 gained 3.5% over the same period, according to CNBC analysis from 28 April.

The divergence reflects investor scepticism about sustained procurement increases. Iran does not require the high-end weapons systems that drive contractor margins — precision-guided munitions, advanced fighters, missile defence batteries. The conflict has instead consumed existing stockpiles without triggering major new orders. Analysts also note that repeated cease-fires and postponements create uncertainty about programme longevity, making multiyear defence outlays harder to justify.

What to Watch

The next 72 hours will clarify whether Gulf mediation produces substantive progress or merely extends stalemate. Key indicators include whether Iran agrees to verifiable Hormuz reopening, the scope of nuclear inspections it will accept, and whether Trump ties any deal to sanctions relief or keeps economic pressure intact.

On Capitol Hill, watch for the timing and language of any formal war powers vote. Moderate Republicans face pressure to either force Trump into seeking authorisation or accept that precedent allows presidents to wage undeclared wars indefinitely. Israel’s response also matters — Netanyahu has publicly questioned whether Trump will accept outcomes that leave Iranian nuclear infrastructure recoverable.

Oil Markets will remain volatile. Brent surged 55% from $72 per barrel on 27 February to nearly $120 at peak, with March alone posting one of the largest monthly gains on record at 51%. Any renewed strike threat could push prices back above $110 within hours, but a credible diplomatic breakthrough could accelerate declines toward $100.

Trump’s comment that “this is a little bit different now” suggests he sees political or strategic value in a negotiated outcome. Whether that reflects genuine optimism, domestic political pressure ahead of the 2026 midterms, or simply another tactical delay before resumption will become clear when the current postponement window closes.
