Oil Surges 10% as Trump Blockades Iran and Claims Hormuz Control
Trump's Iran blockade and a 20% Hormuz shipping toll rattled markets, spiking oil nearly 10% while stocks and bonds sold off sharply.
A dramatic escalation in U.S.-Iran tensions sent crude oil prices surging nearly 10% on Wednesday after President Trump announced a full naval blockade of Iran and declared American control over the Strait of Hormuz — the critical chokepoint through which roughly a fifth of the world's oil supply flows.

Waller warned that another hot core inflation reading this week could force the FOMC to consider raising rates, a comment that pushed market-implied odds of a July 29 hike to roughly 40%. Two-year Treasury yields climbed 5.7 basis points to 4.26%, their highest level since February 2025 — before the Fed's three consecutive rate cuts. The dollar strengthened broadly, with the Australian dollar the session's biggest loser in G10 FX.
The convergence of an energy supply shock and a hawkish Fed repricing is a particularly uncomfortable combination for risk assets.
