US stocks charged higher Monday, with the S&P 500 wiping out its 2026 losses, after President Donald Trump announced a complete naval blockade of the Strait of Hormuz following the collapse of ceasefire talks with Iran.
"This is a game of chicken. It’s who caves first," Nikki Haley, Trump’s former ambassador to the United Nations, said on CNN’s “State of the Union” on Sunday. "The Iranian regime is hoping that Trump will cave. Today, he showed he’s not."
The surprising market reversal saw the S&P 500 gain despite the blockade's dire implications for global energy markets. The energy sector was the session's standout performer, surging more than 4% as Brent crude futures jumped toward $100 a barrel. In contrast, sectors sensitive to consumer spending and higher costs, like consumer discretionary and technology, lagged the broader market.
While markets appeared to interpret the move as a high-stakes negotiating tactic to force Iran back to the table, the blockade introduces significant risk to global energy supplies. A prolonged closure of the strait, which handles over a fifth of the world's seaborne oil, could trigger an inflationary shock to a global economy already on fragile footing.
The blockade was announced via a post on Truth Social after high-level talks in Pakistan between US and Iranian officials ended without a deal. Vice President JD Vance, who led the US delegation, said the talks failed because Iran would not provide an "affirmative commitment that they will not seek a nuclear weapon."
The negotiations were aimed at reopening the critical waterway after Iran began charging ships a $1-per-barrel toll for safe passage, citing unlocated mines in the strait. The US and its allies have refused to pay the toll, which Trump decried as "WORLD EXTORTION."
The market's positive reaction suggests investors may be betting the blockade is a temporary measure that will resolve the standoff more quickly than protracted negotiations. However, the move also dramatically raises the odds of a direct military confrontation. In a statement, Iran’s Revolutionary Guard said the strait remained under its “full control” and that military vessels would receive a “forceful response.”
