On his 80th birthday, Donald Trump secured an agreement to reopen the Strait of Hormuz, a critical maritime chokepoint through which nearly 20% of the world’s oil and gas supplies pass. The deal, announced in mid-June 2026, has the potential to ease inflationary pressures that have burdened global economies in recent years, especially as energy prices surged following the waterway’s closure amid regional conflict.

Since early March, when hostilities led to the strait’s shutdown, global oil prices have increased by approximately 40%, with Asian markets, heavily dependent on Gulf exports, experiencing gas price rises nearing 80%. European gas prices have climbed by nearly half that amount. The energy supply disruption has contributed to an estimated 0.3 to 0.4 percentage point rise in global inflation in 2026, with projections warning the figure could jump another 1 to 1.5 points in 2027 if the closure persisted. Most central banks aim for inflation levels around 2% annually.

The reopening deal arrives amid concerns that summer demand for oil and jet fuel would outstrip dangerously low stockpiles in wealthy nations, risking a more severe energy crisis. Without a resolution, economies with slower growth trajectories, such as the United Kingdom and the eurozone, faced increased odds of recession by year-end.

Trump’s repeated announcements on his Truth Social platform, emphasizing that an agreement was “imminent” on multiple occasions, contributed to significant volatility in oil markets. Anticipation of the reopening pushed prices down toward $80 per barrel—the lowest since March—while European stock markets reached record highs. According to forecasts from Goldman Sachs, a sustained agreement could lower oil prices to about $70 per barrel by late 2026 and return to pre-conflict levels near $60 in 2027.

Operational recovery will take time, with around 600 vessels stranded in the Gulf and numerous empty ships positioned to resume transport. Analysts from Capital Economics estimate that about 80% of pre-war energy supply could be restored by the end of September, though the International Energy Agency cautions that full normalization may extend up to eight months. Gas production recovery will be slower, with Qatar indicating that repairs and capacity restoration at the Ras Laffan gas hub, jointly held with Iran, could require three to five years.

Challenges remain beyond navigational safety, including repositioning tankers, ramping up production and refining, and addressing insurance uncertainties for ships transiting the strait. Details of the 60-day ceasefire extension, nuclear disarmament commitments from Iran, and strait management are expected to be limited ahead of a formal signing ceremony in Geneva.

The Hormuz agreement coincides with this week’s G7 summit in Évian, France, where Trump will meet world leaders. The deal has taken precedence over crucial discussions on issues such as China’s trade surplus and U.S. export controls on artificial intelligence technologies, which have raised concerns about future market optimism and technology adoption rates.

Central banks worldwide have welcomed the development, as inflationary pressures linked to energy and food prices remain elevated. Currently, 46 of the world’s 68 central banks report inflation rates exceeding their targets. The European Central Bank recently ended a three-year pause on interest rate hikes due to inflation forces intensified by the conflict.

In the coming days, six major central banks, including the Bank of England and the U.S. Federal Reserve, along with nine emerging-market central banks, will announce monetary policy decisions. Market participants have largely adopted a cautious stance amid prior inflation fluctuations. The Bank of Japan is anticipated to raise rates despite the ceasefire.

For policymakers such as Bank of England Governor Andrew Bailey and U.S. Federal Reserve appointee Kevin Warsh, the agreement offers welcome respite. The Bank of England, wary of tightening monetary policy amid a fragile jobs market and weak economy, had faced internal debate over raising rates in July. Following the deal, market expectations for a rate increase have diminished to below 25%. Upcoming inflation data, expected to exceed 3%, may represent the peak rather than a sustained rise.

Warsh, making his first policy decision, was appointed in part to support economic growth by potentially lowering rates. The reopening of the Strait of Hormuz is likely to postpone urgent policy adjustments for now, easing immediate inflation concerns tied to energy costs.
