Most Gulf markets advanced on May 25, 2026, driven by investor optimism over a potential US-Iran peace agreement that could stabilize regional security and energy flows, even as analysis suggests Gulf states may be positioning themselves to shape the diplomatic outcome through financial leverage.
Market Response to Diplomatic Shift
Gulf financial markets responded positively to signals that the United States and Iran may be moving away from military confrontation toward negotiated settlement. The market gains reflected investor confidence that a peace deal would reduce regional instability and protect critical energy infrastructure, particularly shipping lanes through the Strait of Hormuz that handle a substantial portion of global oil exports.
According to a Haaretz analysis published May 25, 2026, by Zvi Bar'el, Gulf states appear prepared to provide Iran with economic support that could influence the trajectory of negotiations involving President Donald Trump. The analysis, which appeared in Haaretz's Analysis section under the headline "Gulf States Prepared to Give Iran a Safety Net That May Save Trump From Himself," examined the strategic calculations of regional powers as diplomatic momentum builds.
Strategic Timing and Regional Pressure
The calendar appears to be influencing the pace of diplomacy. President Trump has shown little interest in launching a new offensive before the end of the Hajj pilgrimage and Eid al-Adha, which begins Wednesday and is expected to draw more than 1.5 million pilgrims to Saudi Arabia. Riyadh had already pressed Washington not to resume fighting while pilgrims remained inside the kingdom, fearing that a regional war could leave many stranded.
No one appears to be placing bets anymore on the scenario that, until just a few days ago, looked highly likely: a return to war between the United States and Iran. The shift in expectations has created new opportunities for market stability and economic planning across the Gulf region.
Tehran's Assessment of Negotiations
In Tehran, the prevailing view is that the U.S. president is willing to pay a high price for the appearance of victory. But Trump may enter the next phase of nuclear negotiations without guarantees, leverage or credible deterrence, according to the Haaretz analysis. This assessment by Iranian officials suggests they believe the diplomatic environment favors their negotiating position, potentially complicating efforts to secure verifiable commitments on nuclear development.
The Haaretz article included tags for Saudi Arabia, Iran - U.S., Iran nuclear, United Arab Emirates, Donald Trump and Strait of Hormuz, reflecting the interconnected nature of regional security, energy markets, and great power diplomacy.
Why This Matters:
The Gulf markets' positive response underscores how regional stability directly affects investor confidence and energy security. However, the suggestion that Gulf states may provide Iran with economic support raises questions about leverage in nuclear negotiations. If Tehran enters talks believing it has financial backing from regional powers, the United States may find it harder to secure meaningful concessions on nuclear development and regional activities. The timing around the Hajj pilgrimage demonstrates how religious and cultural factors constrain military options, potentially weakening deterrence. Market optimism is warranted if peace reduces conflict risk, but premature celebration could ignore whether any agreement includes verification mechanisms and enforcement provisions that protect long-term American interests and regional security architecture.
