The U.S.–Iran peace agreement that reopens the Strait of Hormuz and ends the U.S. naval blockade of Iranian ports has simultaneously eased global economic fears and ignited a fierce political battle in Washington.

On June 13, Donald Trump signalled a breakthrough, saying the U.S. and Iran would sign a deal on Sunday "to reopen" the key waterway.¹ Soon after, reports framed the outcome as a "truce of convenience" in which the Islamic Republic survived with its leverage enhanced, despite earlier U.S. promises of "unconditional surrender."²

By June 15, details emerged that Iran and the U.S. had agreed a deal "to open Strait of Hormuz and extend ceasefire," including the end of the U.S. naval blockade of Iranian ports.³ Oil prices fell on the news, even as analysts warned that the Hormuz backlog could last weeks and flows would remain vulnerable to renewed disruption.⁴

Markets quickly shifted from crisis to relief. One analysis noted that the oil market had effectively "shrugged off the Iran crisis," with fears of $200 crude replaced by concerns about looming gluts.⁵ Global equities jumped, as "stocks surge as US-Iran deal ignites global rally," helped by buoyant investor sentiment.⁶ Asian tech shares led the way: "Asian Tech Stocks Surged After the Iran-US Deal, and AI Chipmakers Gained the Most," pushing Japan’s Nikkei to record highs.⁷

Strategically, commentators warned this was "a fragile Iran peace" following "a war without victors," arguing the agreement underscored the failure of a purely military option.⁸ Domestically, coverage stressed that the "Iran deal leaves Trump fighting a war at home," as Republicans split and Americans faced higher prices without a clear sense of victory.⁹

The most explosive argument centered on economic sweeteners. Reports said the "Trump administration considers $300bn fund for Iran if deal is upheld," tying incentives to Tehran’s performance on reopening Hormuz and nuclear talks.¹⁰ As criticism mounted, opponents branded the outcome "humiliation," claiming "Donald Trump Battles Claims His Iran Deal Is Worse Than Obama’s" and questioning whether wartime sacrifices justified the concessions.¹¹

On June 18, the Financial Times reported that the "US and Iran sign deal as Donald Trump vows to release frozen funds and ease sanctions," with the president saying Iranians would receive incentives when they "behave" and acknowledging Tehran would retain its ballistic missiles.¹² Amid bipartisan backlash, Trump publicly pushed back, insisting "Donald Trump says US will not invest in $300bn fund for Iran," directly contradicting earlier suggestions of such a mechanism.¹³

The Iran deal is now shaping debates on U.S. policy well beyond the Gulf. As analysts turn to other regional plans — such as commentary that "The world may not like Trump’s Gaza plan" even if some long-time critics grudgingly accept it as the least bad option¹⁴ — the Hormuz agreement stands as both a relief to markets and a flashpoint over the cost and character of American power.
