Why is the U.S. dollar strengthening against the yen and other major currencies amid Gulf tensions?

The U.S. dollar is holding firm—reaching 162.41 yen, near its strongest level since July 1—due to renewed Gulf tensions that revived safe-haven demand and surged oil prices, which in turn increased market bets on a Federal Reserve interest rate hike; as Kyle Rodda of Capital.com noted, the Middle East flare-up added a 'war risk premium' to asset prices, and the jump in oil prices heightened inflation concerns, prompting markets to price in higher and earlier Fed rates, with the implied probability of a 2024 hike rising to about 87% according to CME FedWatch.

What role did U.S. military action and political statements play in driving oil prices and financial market reactions?

U.S. military strikes on Iran—launched hours after former President Donald Trump declared an interim agreement to end the war 'over'—sent oil prices sharply higher, pushing Brent crude futures to $79.28 a barrel, the highest in over two weeks; this triggered a 'wake-up call' for investors regarding energy-driven inflation pressures, sending U.S. 10-year and 30-year Treasury yields to seven-week highs as markets repriced the risk of imminent Fed rate hikes, further reinforcing dollar strength and yen weakness.
