US Military Strike on Oil Tanker Sparks Asian Market Sell-Off and Oil Price Surge

Asian financial markets experienced significant volatility on Tuesday following a dramatic announcement by US President Donald Trump. The US administration declared it would reinstate sanctions on Iranian oil and goods shipments through the strategic Strait of Hormuz, imposing a 20% tariff on all cargo passing through the waterway. This move triggered sharp declines across major Asian stock exchanges, with the MSCI Asia-Pacific index excluding Japan dropping 1.7%. Taiwan and South Korea led the losses, plunging over 3% and 5% respectively at their lowest points, while Japan’s Nikkei 225 fell 0.8%. In contrast, China’s CSI 300 index showed relative resilience, declining only 0.4%, supported by stronger-than-expected June export and import data.

The geopolitical tensions also caused Brent crude oil futures to surge 1.7% to $84.72 per barrel, reaching an intraday high of $85.64, the highest since mid-June. The market turmoil was compounded by hawkish comments from Federal Reserve Governor Christopher Waller, who warned that the US central bank might need to raise interest rates soon if inflation remains above the 2% target. Investors are now awaiting US consumer price index data and the semiannual testimony of Fed Chair Kevin Warsh to Congress later in the day.

The Asian market upheaval followed a turbulent session on Wall Street, where the S&P 500 closed down 0.8% and the Nasdaq fell 1.6%, amid a sharp 9% jump in oil futures due to escalating US-Iran tensions disrupting the Strait of Hormuz trade route. Futures markets now price a 43.3% chance of a 25 basis point rate hike at the Fed’s July meeting, up from 34.2% last Friday. Meanwhile, the US 10-year Treasury yield rose slightly to 4.624%, and the US dollar index dipped 0.1% to 101.18, near monthly highs. Gold prices increased 0.3% to $4,012.37 per ounce amid the uncertainty.
