Middle East Tensions Push Dollar Higher, Oil Jumps on Hormuz Disruption

The U.S. dollar strengthened against most major global currencies on Monday as renewed military confrontation between the United States and Iran triggered a wave of risk aversion across international financial markets. Investors flocked to the dollar, traditionally regarded as a safe-haven asset during periods of geopolitical uncertainty, after Iran intensified attacks on U.S. military positions in the Gulf and reiterated its closure of the strategic Strait of Hormuz.

The latest escalation follows a weekend of missile and drone exchanges between the two countries, with Iran claiming responsibility for attacks on American military facilities in several Gulf states. Tehran also maintained that shipping through the Strait of Hormuz would remain restricted, further heightening concerns over the security of one of the world’s most important energy transit routes. Around one-fifth of global oil supplies normally pass through the narrow waterway, making any disruption a major concern for global trade and energy markets.

The heightened tensions immediately affected financial markets. The U.S. Dollar Index, which measures the greenback against a basket of major currencies, climbed as investors shifted away from riskier assets. The Japanese yen, euro, British pound, Australian dollar and New Zealand dollar all weakened against the dollar as traders sought the relative safety of U.S. assets.

At the same time, oil prices surged after fears that prolonged disruption in the Strait of Hormuz could significantly reduce global crude supplies. Brent crude rose by more than 4% to trade above $79 per barrel, while U.S. West Texas Intermediate (WTI) crude also posted strong gains. Analysts warned that if the disruption continues, higher energy prices could fuel inflation worldwide and complicate efforts by central banks to bring consumer prices under control.

The stronger dollar was also supported by changing expectations for U.S. monetary policy. Rising oil prices have renewed concerns that inflation could accelerate again, prompting investors to reassess the likelihood of further interest rate increases by the U.S. Federal Reserve. Market pricing now reflects increased expectations that policymakers may keep interest rates higher for longer if inflationary pressures persist.

Global equity markets reacted negatively to the deteriorating security situation. Asian stock markets recorded broad losses, while futures for European and U.S. markets also pointed lower as investors weighed the economic implications of a prolonged Middle East conflict. Bond yields rose alongside the stronger dollar, reflecting expectations of tighter monetary conditions and increased demand for safer investments.

Financial analysts say the coming days will be critical for markets. Investors will closely monitor further developments in the Middle East, upcoming U.S. inflation data and comments from Federal Reserve officials for clues about the future direction of interest rates. Any additional disruption to oil shipments through the Strait of Hormuz could intensify market volatility and place further upward pressure on energy prices, inflation and global borrowing costs.
