US and Iran Exchange Strikes: Oil Jumps and Stocks Slide
The tl;dr
A fragile ceasefire between the US and Iran has broken down, and markets have swung risk-off. Washington launched retaliatory strikes on Iranian military sites after Iran attacked three commercial vessels in the Strait of Hormuz, and it revoked a waiver that had let Iran sell oil; Iran's Revolutionary Guards said they hit US military facilities in the region in response. Crude jumped more than 2%, US stock futures fell around 1%, Europe slipped and Asian markets sold off, with South Korea's Kospi tumbling into a bear market. The moves read as a supply and inflation shock centered on the world's most important oil chokepoint.

By the numbers
A fragile ceasefire between the US and Iran has come apart, and markets have swung sharply risk-off. Washington launched a fresh round of strikes on Iranian military sites after Iran attacked three commercial vessels transiting the Strait of Hormuz, and it revoked a temporary waiver that had allowed Iran to sell oil onto world markets. Iran’s Revolutionary Guards said they retaliated by hitting US military facilities in the region. It is an abrupt return to open confrontation after a stretch of tense de-escalation talks, and investors reacted by selling stocks, buying the dollar and bidding up crude.
The clearest move was in oil. Brent crude rose about 2.2% to near $75.80 a barrel and US West Texas Intermediate climbed about 2.1% to near $71.90, as traders priced in the risk to the Strait of Hormuz, the narrow waterway that carries a large share of the world’s seaborne oil. Equities went the other way: US stock futures pointed sharply lower, with Dow futures down about 1.1%, the S&P 500 around 0.9% and the Nasdaq roughly 1.3%, while Europe’s Stoxx 600 slipped about 0.8%. Asian markets bore the brunt overnight, with Japan’s Nikkei down about 2.1% and South Korea’s Kospi tumbling around 5.4% into a bear market, a slide deepened by a separate selloff in the semiconductor shares that now dominate that index. Away from stocks, government bond yields pushed to one-month highs, gold slipped and the dollar firmed, an unusual mix that points to an inflation and supply shock rather than a classic flight to safety.
That is what makes this episode more than a passing headline. The Strait of Hormuz is the single most important chokepoint in the global oil trade, so any threat to shipping there adds a risk premium to crude and, through higher fuel and freight costs, feeds straight into inflation. As one analyst, Andreas Krieg of King’s College London, put it, Tehran is “sending a clear signal that no alternative will be accepted” on its terms for the waterway. For central banks that had been edging toward rate cuts, a renewed oil spike is an unwelcome complication. The moves so far are orderly rather than a panic, but with the ceasefire in tatters and tankers under attack, the market is keeping a risk premium in oil and a lid on appetite for stocks until the picture clears.
The Strait of Hormuz is the single most important artery in the global oil trade, so any threat to shipping there puts a risk premium straight into crude and, through fuel and freight costs, into inflation. That is why the reaction was not a simple growth scare: stocks fell while oil rose and government bond yields pushed to one-month highs, with gold slipping and the dollar firming as the haven of choice. Markets are treating this as a supply and price shock rather than a pure risk-off flight, which is a more awkward mix for central banks that had been leaning toward rate cuts. The moves are contained for now, not a panic, but with a ceasefire in tatters and tankers under attack, the risk of a bigger disruption keeps a floor under oil and a lid on risk appetite.
