US-Iran Peace Deal Reopens Strait of Hormuz as Markets Weigh Geopolitical Shifts
The United States and Iran have reached an agreement to end their nearly four-month conflict, with both sides announcing the immediate termination of military operations and plans to reopen the Strait of Hormuz. Pakistan Prime Minister Shehbaz Sharif confirmed the breakthrough, while US President Donald Trump declared the deal complete and authorized the lifting of the US naval blockade. The development marks a significant de-escalation in the Middle East and is already influencing global financial markets.
The pact, which takes effect on Friday, includes provisions for toll-free passage through the strategically vital Strait of Hormuz and the eventual release of frozen Iranian assets. Iranian officials emphasized that final nuclear negotiations would proceed once commitments under a memorandum of understanding are met, including the complete end of the maritime blockade.
Key Takeaways:
- The US-Iran peace deal has been reached, with both sides agreeing to end military operations and reopen the Strait of Hormuz.
- The deal includes provisions for toll-free passage through the Strait and the eventual release of frozen Iranian assets.
- Oil prices have tumbled by over 3.5% following the announcement, with West Texas Intermediate crude oil prices trading near $79.40–$79.70 per barrel.
- The US Dollar has weakened broadly as geopolitical risk aversion eased, with major currency pairs reflecting this shift.
- Global markets have responded positively to the development, with analysts attributing the positive sentiment to the restored oil flows through the Strait of Hormuz.
Background to the US-Iran Agreement
Tensions escalated in late February 2026 following airstrikes involving US and Israeli forces. The conflict disrupted oil flows through the Strait of Hormuz, a critical chokepoint for global energy supplies. The new framework aims to restore stability, with both nations agreeing to halt operations across multiple fronts, including Lebanon.
US President Trump stated that the agreement would ensure the Strait remains “permanently toll free,” despite reported objections from Israeli Prime Minister Benjamin Netanyahu. Trump also indicated that failure to secure a final nuclear accord could lead to resumed military measures or alternative US involvement in the region.
European powers have responded positively. The United Kingdom, France, Germany, and Italy signalled readiness to lift sanctions on Iran contingent on progress regarding its nuclear programme, according to Reuters.
Oil Markets Tumble on Eased Supply Concerns
West Texas Intermediate (WTI) crude oil prices fell sharply following the announcement, trading near $79.40–$79.70 per barrel in early Asian sessions on 15 June 2026. This represents a decline of more than 3.5% on the day and marks a two-month low.
Analysts attribute the drop to expectations of restored oil flows through the Strait of Hormuz, which had been effectively closed since the outbreak of hostilities. The American Petroleum Institute (API) weekly crude inventory report, due later on Tuesday, will provide further insight into supply-demand dynamics.
The agreement introduces uncertainty, however. Iranian commitments hinge on US actions, and any delays could affect market sentiment. For participants monitoring commodity-linked currencies, developments in energy prices remain a key variable.
Currency Markets Respond to Reduced Risk Aversion
The US Dollar weakened broadly as geopolitical risk aversion eased. Major currency pairs reflected this shift during Monday’s Asian trading.
AUD/USD advanced toward 0.7075, supported by improved risk sentiment for commodity currencies. The Reserve Bank of Australia (RBA) is expected to hold its cash rate at 4.35% at its June meeting on Tuesday, with markets paring bets on further tightening.
EUR/USD climbed to around 1.1610. The euro benefited from the softer dollar, even as the European Central Bank (ECB) continues its tightening cycle. The ECB recently raised rates for the first time in three years and revised upward its inflation projections for 2026 and 2027.
GBP/USD rose to near 1.3450. The pound gained amid the improved market mood ahead of the Bank of England’s (BoE) policy decision on Thursday, where rates are widely expected to remain unchanged following recent UK economic data showing a slight contraction.
USD/CAD declined toward 1.3970, pressured by lower oil prices despite Canada’s position as a major crude exporter to the US.
NZD/USD held firm near 0.5850 despite soft New Zealand services sector data, which showed continued contraction.
USD/JPY remained relatively steady around 160.20. The Japanese yen showed limited movement as attention turns to the Bank of Japan’s (BoJ) expected rate hike to a 31-year high on Tuesday.
The People’s Bank of China set the USD/CNY central reference rate at 6.8088, compared to 6.8109 previously.
Gold Price Rebounds Modestly
Gold (XAU/USD) attracted buyers and reached a weekly high in Asian trading. The precious metal benefited from lingering uncertainties around the peace process, though it remains below its 100-day simple moving average. Markets have slightly reduced expectations for a US Federal Reserve rate hike in December following the announcement.
Geopolitical developments can influence safe-haven demand, while higher interest rate expectations generally weigh on non-yielding assets such as gold.
Broader Economic Context
The US-Iran agreement comes at a time when central banks globally are navigating inflation pressures partly linked to energy costs. The ECB’s upward revisions to inflation forecasts highlight persistent challenges, while other monetary authorities monitor both domestic data and international developments.

Outlook and Remaining Uncertainties
While the ceasefire and reopening of the Strait of Hormuz represent a positive step toward stability, several conditions remain. Iranian officials have stressed the need for immediate implementation of US commitments, including the release of approximately $12 billion in frozen assets.
Central bank decisions this week — from the RBA, BoJ, and later the Federal Reserve — will provide additional direction. The BoJ is anticipated to raise rates to 1.0%, with further increases projected later in the year.
The US-Iran peace deal has already produced measurable effects across oil, currency, and commodity markets. As implementation progresses and final nuclear talks advance, participants will continue to assess the implications for global economic stability and financial asset pricing.
