U.S. Strikes on Iran Stall Stocks as Rising Oil Prices Fuel Global Inflation Fears

Stocks lost momentum as conflicting signals from Washington and Tehran unsettled investors, with renewed U.S. strikes on Iran, rising oil prices and fresh uncertainty over the Strait of Hormuz all weighing on sentiment. Traders had been parsing reports that suggested both a possible path toward de-escalation and a harder U.S. line, leaving Wall Street without a clear direction by the close, according to Bloomberg’s market coverage.

The tug-of-war in markets reflected the latest swing in the U.S.-Iran confrontation. Bloomberg reported that the White House dismissed an Iranian media account of progress in peace talks as a “complete fabrication,” while other Bloomberg audio updates said President Donald Trump disputed Iran’s control over Hormuz and said Iran would not get sanctions relief. At the same time, Bloomberg market reports said fresh attacks in the Gulf and U.S. strikes on Iran revived concern that the conflict could disrupt energy flows through one of the world’s most important shipping lanes.

That uncertainty hit asset prices broadly. Stocks and bonds fell while oil climbed, according to Bloomberg’s market wrap, and gold slipped to a two-month low as a stronger dollar and renewed conflict damped expectations for a quick peace deal. Treasury prices also weakened as investors began to price in the possibility that higher crude costs could feed through to inflation, Bloomberg reported.

The energy shock is already showing up beyond Wall Street. Britain’s regulator said household energy bills will rise, with a typical user set to pay £221 more a year, as the broader impact of the Iran war pushes up costs, BBC News reported. Bloomberg also said British food and drink manufacturers are preparing to raise prices, while South Africa’s central bank is reportedly considering its first rate hike since 2023 because of inflationary pressure from higher oil.

For investors, the biggest question is whether the confrontation disrupts the Strait of Hormuz, through which a large share of global crude and fuel shipments pass. Bloomberg said traders remain focused on whether diplomacy can reopen a path to calmer relations or whether the fighting will deepen and keep oil elevated, a prospect that would complicate the outlook for inflation, interest rates and corporate profits.

The market reaction was uneven but pointed in the same direction: risk assets struggled, commodity prices surged and safe-haven flows shifted as the news cycle around Iran changed by the hour. Bloomberg’s coverage suggested that until there is clearer evidence of either a ceasefire or a broader escalation, investors are likely to keep reacting to every new statement from Washington and Tehran.
