New exchanges of strikes between U.S. and Iranian forces have undone a recent, tenuous ceasefire and redirected investor attention to shipping through the Strait of Hormuz. The renewed military activity and the U.S. reinstatement of crude sales sanctions on Iran have amplified concerns about the pace of supply recovery from the Middle East.
Oil reacted quickly - Brent crude futures climbed roughly 2% as markets priced in the possibility of prolonged supply disruption. The key waterway for Middle Eastern oil exports, the Strait of Hormuz, has remained a focal point since the conflict began at the end of February, and the latest hostilities have left traders anxious about how long disruptions might linger.
Global equity markets, by and large, absorbed the latest U.S. strikes on Iran without dramatic moves, but the energy complex showed immediate stress. Investors are cautiously hoping that the recent jump in Brent will be contained and that supply can return to normal in time.
Fixed income markets reflected the higher inflation risk signaled by rising oil. The U.S. 10-year Treasury yield increased by about 3 basis points to a one-month high at 4.565%, a move that typically corresponds to falling bond prices. That uptick feeds into broader inflation concerns and the pricing of future monetary policy.
All eyes are set on the Federal Reserve minutes from the June policy meeting, due later in the U.S. trading day. Market participants will examine those minutes for a clearer sense of policymakers' tone and appetite for further tightening. Current market pricing assumes the Fed will raise rates at least once by the end of 2026 to rein in inflation.
In equities, technology names will be scrutinized after a turbulent period. The recent momentum generated by the historic, blockbuster IPO of SpaceX has given way to questions about whether the AI-driven rally can sustain additional gains. Investor sentiment in the sector has been volatile.
South Korea captured headlines after chipmaker SK Hynix initiated a U.S. share offering on Monday that aims to raise 43 trillion won.

Market observers see the move as another test of investor appetite for technology and semiconductor exposure following recent swings.
The KOSPI index fell another 5%, prompting the Korea exchange to trigger a short trading halt. Such halts have become more frequent, underscoring the elevated volatility in what has been the world's top-performing equity market until recently.
