Equity Futures Surge 1.8% as Trump Halts Iran Strikes for Two Weeks
Two-week ceasefire suspends five-plus-week conflict, triggering largest oil price collapse since 1991 Gulf War and compressing geopolitical risk premium across macro assets.
US equity index futures rallied up to 1.8% late April 7 after President Trump announced a two-week suspension of military operations against Iran, conditional on Tehran reopening the Strait of Hormuz. The abrupt reversal — delivered 90 minutes before Trump’s final 8 p.m. ET deadline to strike Iranian civilian infrastructure — triggered the sharpest one-day oil price collapse since the 1991 Gulf War and unwound weeks of geopolitical risk premium embedded in equities, rates, and energy markets.
S&P 500 futures gained 1.6%, Nasdaq 100 futures climbed 1.8%, and Dow futures jumped 725 points in overnight trading following the announcement, per NBC News. Brent crude plunged 13% to approximately $95 per barrel while WTI dropped 14% to $96, according to Axios, marking the largest single-day decline in oil prices since the Gulf War. US crude had traded near $103 per barrel just hours before Trump’s Truth Social post announcing the ceasefire.
The rally reverses sharp losses driven by escalation fears since the conflict began February 28. Iran’s March 2 closure of the Strait of Hormuz — which handles roughly 20% of global oil supply — had driven Brent from $75 at the start of 2026 to peaks near $120 as physical market premiums surged $30-40 per barrel above futures. Equities absorbed the dual headwind of supply-shock inflation risk and demand destruction fears, with Energy-intensive sectors facing margin compression and recession probability estimates climbing.
Ceasefire Framework and Diplomatic Timeline
Trump’s announcement came after Pakistan brokered intensive mediation between Washington and Tehran. “This will be a double sided CEASEFIRE,” Trump wrote on Truth Social, citing completion of “all Military objectives” and progress toward “a definitive Agreement concerning Longterm PEACE with Iran.” Iran’s Foreign Minister Seyed Abbas Araghchi confirmed that Iranian forces would “cease their defensive operations” if US attacks halted, according to NBC News.
Delegations are scheduled to meet in Islamabad on April 10 for formal talks. Pakistan Prime Minister Shehbaz Sharif praised both parties for displaying “remarkable wisdom” in pursuing stability, according to NewsNationNow. Iran transmitted a 10-point proposal to Trump on April 7 that includes demands for sanctions relief, nuclear enrichment rights, US military withdrawal from the region, and reparations, according to NPR.
Oil Market Dynamics and Reopening Risk
The ceasefire announcement compressed war-premium pricing that had dominated energy markets for five weeks. Brent futures had already retreated to $109 per barrel by April 6 morning on diplomatic optimism before the formal ceasefire triggered the additional decline. The magnitude of the drop reflects not just headline de-escalation but trader expectations that physical shipments through Hormuz will resume within days.
“Ship operators’ confidence that they won’t be attacked is the one and only litmus test to assess whether energy flows are likely to resume.”

Yet physical market normalisation hinges on factors beyond diplomatic declarations. Tanker operators require insurance coverage restoration, navy escort coordination, and demonstrable Iranian commitment to safe passage. Any incident during the two-week window — accidental or deliberate — would immediately reprice tail risk and could trigger sharper volatility than the initial closure. Markets are effectively front-running a fragile outcome with binary payoff structure.
Energy majors that benefited from sustained triple-digit crude now face margin compression as refined product spreads narrow. Conversely, airlines and transport-heavy logistics firms gained in overnight futures trading on expectations of lower jet fuel and diesel costs, per FinancialContent analysis. The S&P 500 had already posted a 3.4% weekly gain through April 6 as diplomatic progress lifted the “war discount” priced into equities.
Tail Risk Repricing and Macro Implications
The ceasefire removes the most acute geopolitical tail risk facing global markets — a sustained Hormuz closure coupled with broader Middle East conflagration. That scenario would have forced central banks to choose between tolerating energy-driven inflation or tightening into supply-shock recession. The Federal Reserve had publicly signaled concern about stagflation risks if crude remained above $110 for an extended period.
Markets entered 2026 pricing stable oil near $75 per barrel and steady Fed policy. The 60% surge to $120 during the conflict compressed equity multiples, widened credit spreads, and triggered inflation hedge flows into commodities and gold. A sustained return to sub-$100 oil would reverse these dynamics, supporting both earnings estimates and Fed dovish optionality.
However, the two-week timeline creates event risk concentration. If talks collapse or Iran fails to reopen the Strait as promised, markets face whiplash worse than the initial shock. Traders have now priced in permanent de-escalation; any reversal would trigger forced liquidation of recently established long positions in cyclicals and energy-sensitive sectors. Defense contractors, which rallied throughout the conflict on expectations of sustained elevated spending, face rotation pressure if peace holds.
Trump’s framing of the ceasefire as vindicating US military objectives — “we have already met and exceeded all Military objectives” — suggests domestic political pressure to lock in gains rather than risk prolonged entanglement. White House Press Secretary Karoline Leavitt characterised the outcome as “a victory for the United States,” according to CBS News. But Iran’s 10-point proposal demands concessions — particularly on sanctions and nuclear enrichment — that would face significant Congressional opposition if formalised.
What to Watch
Physical oil flows through Hormuz in the next 48-72 hours will determine whether the market rally sustains or reverses. Tanker tracking data, Lloyd’s insurance guidance, and US Navy escort announcements provide real-time signals on reopening credibility. If no vessels transit by April 10, expect premium compression to partially unwind.
- Tanker AIS tracking through Hormuz — first commercial transit timing and vessel count
- WTI-Brent spread normalisation — physical premium collapse signals supply restoration confidence
- Islamabad talks progress on April 10 — Iranian nuclear/sanctions demands vs US withdrawal timeline
- Defense sector rotation — sustained underperformance confirms market pricing permanent de-escalation
- Fed commentary shift — any indication dovish tilt returns if oil holds sub-$100
Equity investors should monitor sectoral rotation velocity. Airlines, consumer discretionary, and rate-sensitive growth stocks benefit most from sustained de-escalation and lower energy input costs. Energy producers and defense contractors face dual headwinds of lower commodity pricing and reduced conflict premium. The next two weeks function as a live stress test of whether diplomatic frameworks can contain geopolitical tail risk — or merely postpone it.
