Iranian military strikes on energy infrastructure across nine countries triggered a global market selloff, with the S&P 500 dropping 2.5% and Korean stocks plunging 12% in the sharpest regional decline. A critical strike halted Qatar LNG production, sending European natural gas prices up 85% as traders priced in supply disruptions.
Korean markets suffered disproportionately due to the country's heavy reliance on energy imports and proximity to geopolitical tensions. The 12% single-day decline ranks among the steepest in recent history, with technology and manufacturing sectors leading losses. Japan and other Asian exporters also fell sharply on contagion fears.
The Qatar LNG halt raises immediate concerns for winter heating supplies across Europe and Asia, both heavily dependent on liquefied natural gas imports. European utilities scrambled to secure alternative sources as the continent faces its most acute energy crisis since Russia's 2022 supply cuts. Asian spot LNG prices jumped in parallel with European benchmarks.
The crisis complicates Federal Reserve policy as Chair Jerome Powell delivers semiannual testimony to Congress. Rising energy prices threaten to reignite inflation just as central banks globally had begun easing monetary policy. Treasury yields climbed as investors reassessed rate expectations across major economies.
Market observers discussed a potential Fed-Treasury "accord" that could coordinate monetary policy with debt management. Former Fed Vice Chair Richard Clarida suggested such a framework could help reduce the Fed's balance sheet through coordination with Treasury and housing agencies Fannie Mae and Freddie Mac. Critics warn it could function as yield-curve control, explicitly tying monetary operations to deficit spending.
Currency markets reflected the flight to safety, with the dollar strengthening against emerging market currencies from Turkey to South Africa. Gold prices rose modestly as investors worldwide sought safe-haven assets. The coordinated nature of the strikes exposed vulnerabilities in global energy infrastructure that markets had previously discounted.
