Asia Markets Plunge as Iran Conflict Escalates; Kospi Crashes 10%, Oil Soars
BANGKOK — Financial markets across Asia-Pacific tumbled on Wednesday, mirroring a global sell-off that began on Wall Street, as escalating military tensions with Iran sent shockwaves through investor sentiment and propelled energy prices higher.
The deepening conflict has triggered a flight from risk assets worldwide, with analysts pointing to soaring oil prices and their potential to re-ignite inflation as the primary drivers of the panic. The surge in energy costs threatens to stifle global economic growth and squeeze corporate earnings.
South Korea's Kospi index bore the brunt of the sell-off, nosediving as much as 10% and triggering a temporary trading halt. The dramatic fall overshadowed recent optimism surrounding the AI-driven rally in local tech giants like Samsung Electronics and SK Hynix, highlighting how geopolitical risks can swiftly eclipse sector-specific narratives.
By midday, the Kospi was down 9.6% at 5,235.72.
Japan's Nikkei 225 slumped 3.9% to 54,090.11. Like South Korea and Taiwan, Japan is heavily reliant on oil and natural gas imports from the Middle East, leaving its economy acutely vulnerable to supply disruptions in the Persian Gulf.
Other major regional benchmarks followed suit: Hong Kong's Hang Seng fell 2.8% to 25,037.92, while the Shanghai Composite dropped 1.3% to 4,069.09. Australia's S&P/ASX 200 declined 2% to 8,896.50. Taiwan's Taiex lost 3.4%, and shares in Jakarta sank 3.7%.
The rout followed a turbulent session on Wall Street, where the S&P 500 closed 0.9% lower after an intraday plunge of 2.5%. The Dow Jones Industrial Average finished down 0.8%, and the Nasdaq composite fell 1%.
Market strategists warn that a sustained oil price shock could complicate the Federal Reserve's path. While the Fed signaled potential rate cuts for 2026 after several reductions last year, a resurgence of inflation driven by conflict may force it to maintain a tighter monetary policy for longer, jeopardizing hopes for economic stimulus.
In commodities trading, U.S. benchmark West Texas Intermediate crude climbed 1.2% to $75.46 per barrel. The international standard, Brent crude, gained 1.5% to $82.61 per barrel.
The dollar held steady at 157.55 Japanese yen, while the euro edged down to $1.1599 from $1.1600.
David Chen, Portfolio Manager in Hong Kong: "This is a classic risk-off event. The market is repricing for prolonged instability and higher input costs across the board. Until there's clarity on a diplomatic off-ramp, volatility will remain the dominant theme."
Akiko Tanaka, Economist at a Tokyo Research Firm: "The immediate concern is energy security for import-dependent nations. The secondary, and perhaps more damaging, effect is the inflationary pass-through. Central banks' hands are effectively tied now."
Marcus Thorne, Independent Trader (posted on social media): "Absolute carnage. Where were the 'hedges'? Everyone was chasing AI hype while the real threat was brewing in the Strait of Hormuz. This exposes the complete fragility of the current market narrative."
Priya Sharma, Retail Investor from Mumbai: "It's frightening to see a decade's worth of gains wiped out in days. It feels like we're just passive spectators to these geopolitical storms that decide our financial future."
