A major escalation in the Middle East occurred when the U.S. and Israel launched a surprise military strike on Iran, resulting in the death of Iran's supreme leader, Ayatollah Ali Khamenei. The conflict, now in its seventh day, has led to ongoing fighting and significant turmoil across the region, with continued Israeli airstrikes on Tehran and Iranian missile and drone attacks, including a strike on a Bahraini oil refinery. The U.S. has also suspended operations at its embassy in Kuwait, and Qatar has halted liquefied natural gas production due to attacks on its facilities and the effective closure of the Strait of Hormuz [2][3][5][6].
The Strait of Hormuz, a critical passage for about 20% of the world's daily oil supply, has seen almost no tanker traffic since the start of the conflict, causing global supply concerns and surging oil prices. U.S. crude oil prices rose by more than 20% since Sunday, briefly exceeding $82 per barrel, while Brent crude reached as high as $85.41 before easing to around $85 per barrel. WTI crude is up over 17.5% for the week, trading near $80 per barrel. The spike in oil prices has driven up retail gas prices in the U.S. by more than 30 cents to $3.25 per gallon and pushed Treasury yields higher, with the 10-year yield above 4.1% and the 30-year at 4.75%. The average 30-year mortgage rate hit 6.13% [3][4][5][6][7].
Global equity markets have experienced heightened volatility. Asian markets were mixed: South Korea’s Kospi saw a 12% loss on Wednesday followed by a 10% rebound, Tokyo’s Nikkei 225 closed higher, and Hong Kong’s Hang Seng jumped 1.6%. In contrast, Australia’s S&P/ASX 200 and India’s Sensex declined. European stocks opened higher on Friday as oil prices eased, but the pan-European Stoxx 600 is on track for a 4.6% weekly loss, its worst since April 2025. In the U.S., the S&P 500 fell 0.6%, the Dow lost 1.6%, and the Nasdaq dropped 0.3% on Thursday. Energy stocks outperformed, while airlines suffered significant losses due to higher fuel costs and stranded passengers [3][6][7].
In response to the crisis, the U.S. administration is considering several policy tools to temper oil and gasoline price spikes, including releasing crude from strategic reserves, waiving fuel-blending requirements, and potentially intervening in oil futures markets. The U.S. has also announced insurance guarantees and naval escorts for tankers in the Strait of Hormuz. Additionally, a 30-day waiver was granted to Indian refiners to purchase Russian oil, reflecting efforts to stabilize supply and cap prices. However, analysts note these measures may not be a 'game-changer' and uncertainty remains high [4][5][7].
Forward-looking statements from U.S. officials indicate the conflict is far from over. Defense Secretary Pete Hegseth stated, 'we have only just begun to fight,' warning of further escalation and increased U.S. and Israeli military capabilities in the region. Market participants remain cautious, watching for further disruptions to energy flows and the potential for additional volatility in equities, currencies, and commodities [7].
CONCLUSION
The U.S.-Israel strike on Iran has triggered a surge in oil prices, significant volatility in global equity markets, and disruptions to energy supply chains. While policy responses have temporarily eased oil prices, the ongoing conflict and uncertainty over the Strait of Hormuz continue to weigh heavily on market sentiment. Investors remain on edge as the situation develops, with the potential for further market-moving events in the days ahead.
