Global Markets Tumble as U.S. Strikes Iranian Rockets and Fed Hike Looms

TOKYO — Asian stock markets and U.S. futures retreated sharply on Monday as investors reacted to a dual shock: a surprise U.S. military strike on Iranian rocket launchers and heightened expectations of an interest rate hike by the Federal Reserve.

The volatility began in the early hours after U.S. forces launched precision strikes against mobile rocket launcher sites near the Strait of Hormuz, a critical chokepoint for global energy shipments. The operation, conducted without prior public warning, triggered immediate fears of regional escalation and potential disruptions to oil flows. In response, crude oil prices surged more than 4 percent, pushing Brent futures above $105 per barrel as traders priced in supply risks.

Simultaneously, financial markets braced for tighter monetary policy. The Federal Reserve is widely expected to announce an interest rate increase later this week, a move intended to curb persistent inflation but one that threatens to dampen economic growth and weigh on equity valuations. The combination of geopolitical instability and anticipated higher borrowing costs created a perfect storm for global risk assets.

In Asia, major indices closed in the red. Japan's Nikkei 225 fell 1.8 percent, while South Korea's Kospi dropped 2.1 percent. China's Shanghai Composite also declined, reflecting broader investor anxiety. In the United States, futures for the S&P 500 and Nasdaq Composite pointed to a lower open, with energy and defense sectors showing mixed performance as oil prices climbed.

The U.S. military confirmed the strikes were a defensive measure against imminent threats but provided no details on casualties or the extent of damage to Iranian capabilities. Tehran has not yet issued an official statement regarding the attack, though state media outlets have condemned the action as an act of aggression. The lack of immediate response from Iranian leadership left markets uncertain about the potential for retaliatory measures.

Economists noted that the timing of the military action coinciding with the Federal Reserve's policy decision created a complex environment for central banks and investors alike. "The market is struggling to digest two major negative catalysts at once," said one senior strategist in New York, who spoke on condition of anonymity. "Geopolitical risk premiums are spiking just as the cost of capital rises."

As trading continued into the afternoon session, uncertainty remained high regarding the next steps in the Middle East conflict and the magnitude of the Federal Reserve's rate adjustment. Analysts are closely monitoring whether Iran will respond with further military action or cyberattacks, which could drive oil prices even higher and deepen the global economic slowdown. The situation remains fluid as diplomats attempt to de-escalate tensions while markets await clarity on both the geopolitical and monetary fronts.
