US futures and Asian shares open lower, oil prices soar as US and Israeli attack Iran

Financial markets worldwide experienced significant turbulence early Monday following military actions by the United States and Israel against Iranian targets. The geopolitical escalation triggered immediate reactions across global asset classes, with risk-off sentiment dominating trading patterns.

Asian equity markets opened substantially lower, with Japan’s Nikkei 225 index plummeting 2.4% to 57,430.18 and Australia’s S&P/ASX 200 declining 0.4% to 9,159.60. U.S. stock futures pointed to sharp opening losses, with S&P 500 futures down 1.1%, Dow Jones Industrial Average futures falling 1.2%, and Nasdaq composite futures slipping 1.1%.

The energy sector witnessed dramatic movements as Brent crude oil surged 7.5% to $78.33 per barrel while U.S. benchmark crude skyrocketed 6.8% to $71.58. The price surge reflects mounting concerns about potential disruptions to Middle Eastern energy exports, particularly through the critical Strait of Hormuz waterway where recent attacks have already constrained shipping activities.

Safe-haven assets experienced substantial inflows, with gold climbing 2.3% to $5,380.60 and silver advancing 2.1% as investors sought protection from market volatility. Treasury yields declined as capital moved toward government debt instruments.

Market analysts emphasized the strategic significance of the affected region, with Stephen Innes of SPI Asset Management noting, ‘Roughly one-fifth of global oil and LNG flows squeeze through the Strait of Hormuz. This is not an obscure canal. It is the aorta of the global energy system.’

The inflationary implications of sustained energy price increases present additional complications for monetary policy. Friday’s wholesale inflation data showing a 2.9% year-over-year increase—substantially exceeding economists’ 1.6% expectation—had already created uncertainty about the Federal Reserve’s timing for interest rate reductions. Higher energy prices could further delay anticipated rate cuts, maintaining pressure on both equity valuations and economic growth prospects.

Iran’s daily export volume of approximately 1.6 million barrels, primarily destined for China, represents another potential supply disruption factor that could sustain elevated energy prices if military actions persist.
