Global Stocks Surge on US-Iran Peace Deal Signals — May 25, 2026

Global equities climbed to record highs on May 25, 2026, as US-Iran peace deal momentum lifted the S&P 500 to 7,542 and sent Brent crude tumbling nearly 5% to two-week lows.

On Monday, May 25, 2026, global financial markets staged a broad-based rally after President Donald Trump announced on Truth Social that a peace framework between the United States and Iran had been "largely negotiated" and was awaiting finalization. The statement, following a call with leaders from Saudi Arabia, the UAE, Qatar, Pakistan, Turkey, Egypt, Jordan and Bahrain, ignited a decisive risk-on wave across equities, currencies and commodity markets, pushing the S&P 500 to 7,542 — a gain of 0.92% — while oil prices tumbled to two-week lows.

Markets Price In a "Peace Dividend"

The peace dividend trade swept through virtually every major asset class. S&P 500 futures climbed 0.9% during the holiday-thinned session with US markets closed for Memorial Day. The MSCI All Country World Index, the broadest gauge of global equities, rose 0.4% to a fresh all-time high. Europe's Stoxx 600 extended its winning run to a sixth consecutive session, reaching its highest intraday level since the outbreak of the US-Iran war earlier in 2026.

In prior weeks, the Dow Jones Industrial Average had already surged 600 points in a single session as the first Hormuz ceasefire signals emerged, with the S&P 500 posting its first close above 7,300 in that rally. The May 25 session extended those gains as Trump's post signaled the most concrete diplomatic progress yet, underpinning record equity levels across both developed and emerging markets.

The US dollar weakened against all of its Group-of-10 peers, reflecting the reduction in safe-haven demand as geopolitical risk premiums unwound rapidly. Spot gold briefly surged above $4,699 an ounce on earlier sessions tied to war fears before pulling back as peace prospects materialized.

Oil Craters as Hormuz Reopening Beckons

The most dramatic market reaction unfolded in crude oil markets. Brent crude futures fell $4.71, or 4.55%, to $98.83 a barrel — with both Brent and West Texas Intermediate touching their lowest levels since May 7. WTI dropped $4.57, or 4.73%, to $92.03 a barrel.

The Strait of Hormuz, which before the conflict carried one-fifth of global oil and liquefied natural gas shipments, has been partially blocked since US and Israeli strikes on Iran began on February 28, 2026. Weeks of disruption had pushed Brent crude from pre-conflict levels to above $110 a barrel, fuelling global energy price shocks, demand destruction, and supply dislocations across refining markets worldwide.

MST Marquee analyst Saul Kavonic noted that "notwithstanding all the caveats and risks that remain to the peace deal and Strait of Hormuz, there is now some light at the end of the tunnel, which will bring some near-term oil price relief." However, analysts across major banks emphasized that even a signed agreement would take months before normalized shipping flows and repaired oil infrastructure fully restore global crude supply chains.

The Diplomatic Backdrop: A 14-Point MoU Takes Shape

The market-moving optimism rests on a rapidly intensifying multi-party diplomatic effort brokered primarily through Pakistan, which emerged as the principal intermediary between Washington and Tehran following the collapse of Oman-led talks in late February. Pakistani army chief Field Marshal Asim Munir visited Tehran on May 23, generating what Pakistani military officials described as "encouraging progress toward a final understanding."

Iranian Foreign Ministry spokesman Esmail Baghaei confirmed on state television that the parties were finalizing a 14-point memorandum of understanding designed to serve as a temporary ceasefire framework. Under the proposed arrangement, Iran and the United States would spend 30 to 60 days after signing the MoU negotiating the most contentious issues — Iran's nuclear enrichment program, sanctions relief, release of frozen Iranian assets worth approximately $12 billion held in Qatar, and rules governing ship passage through the Strait of Hormuz.

Baghaei captured the precarious state of affairs in a phrase that circulated widely across Iranian media: "The agreement is both very far and very close."

US Secretary of State Marco Rubio, speaking in New Delhi, struck a similarly cautious tone, acknowledging "some progress" while warning that no breakthrough was guaranteed. "There may be news later today. I don't have news at this very moment, but there might be some news a little later today," Rubio told reporters Saturday. "There may not be. I hope there will be, but I'm not sure yet."

Hardliners, Public Skepticism Cloud the Path Forward

Despite the market euphoria, significant political and diplomatic headwinds remain. Within Iran, hardline factions have been openly hostile to the negotiations. Members of the Iranian parliament's National Security Committee accused Washington of undermining talks through what they characterized as "maximalist approaches." Iran's state news agency IRNA warned the process "could collapse at any moment."

An online poll by the conservative Iranian website Tabnak found that nearly 70% of more than 110,000 respondents predicted no agreement would be reached and that the war would resume — a signal of the deep domestic skepticism inside Iran toward any deal with the United States.

Trump himself kept the military option explicitly on the table, saying on Sunday it was a "solid 50/50" whether the sides would sign an agreement or the US would "blow them to kingdom come." The Financial Times, citing mediators briefed on the talks, reported Washington and Tehran were close to extending the current ceasefire by 60 days as a bridging measure while nuclear and Hormuz terms were negotiated separately.

Sector Winners and Global Market Ripples

The risk-on rotation produced sharp sector-level divergences. Airlines and travel stocks led rallies in Europe and Asia, with Ryanair jumping nearly 11% on earlier Hormuz reopening signals, while British Airways parent IAG, easyJet, Lufthansa, and French hotel group Accor all surged over 6%. The S&P 500's energy sector index fell over 3% as oil majors repriced lower crude forward curves.

Semiconductor and technology stocks extended gains independent of the Iran narrative, continuing a separate AI-driven momentum rally that had already pushed the Nasdaq Composite to 26,343. The Russell 2000 outperformed large caps on the day, rising 0.91% to 2,869, as small-cap equities benefited disproportionately from lower energy costs and improved consumer sentiment.

In bond markets, UK gilt yields — which had spiked to 28-year highs during peak conflict fears — pulled back meaningfully, with the 30-year yield easing to 5.6% and the 10-year gilt falling 11 basis points to 4.9%, reflecting a broad normalization of geopolitical risk premiums.

What Comes Next

The framework as currently constituted would be an interim agreement — a temporary ceasefire extension with structured negotiations over the most consequential issues. Key unresolved disputes include Iran's demand for access to $12 billion in blocked Qatar-held funds as a precondition for signing, Hormuz transit rules that Tehran insists must reflect new Iranian-set protocols, and Washington's insistence on placing Iran's highly enriched uranium stockpile at the center of any broader nuclear deal.

Market participants are watching for formal announcements from either Washington or Tehran that the MoU has been signed, which would represent the most significant de-escalation in the Middle East in years and could unlock a sustained rally in global risk assets while delivering a potentially sharp decline in global energy prices.

For now, the world's financial markets have delivered their verdict: any credible path toward peace is worth pricing in aggressively — even before the ink is dry.
