Asian financial markets experienced severe declines on Monday as escalating threats between Washington and Tehran intensified concerns about the ongoing Iran conflict, now entering its fourth week. Japan’s Nikkei 225 benchmark plummeted 3.4% during morning trading sessions, while South Korea’s Kospi index witnessed a dramatic 5% drop. The regional selloff came in response to heightened geopolitical risks that threaten to destabilize global energy supplies.
The market turbulence follows President Donald Trump’s stark ultimatum delivered via social media on Saturday, warning that the United States would “obliterate” Iranian power facilities unless Tehran reopened the strategically vital Strait of Hormuz within 48 hours. Iran’s parliamentary speaker Mohammad Bagher Ghalibaf responded with a counter-threat, vowing to target regional energy and desalination infrastructure if Iranian power plants faced attack.
This exchange represents a significant escalation in the conflict that began with US-Israeli strikes on Iran on February 28th. Since then, Iran has effectively blockaded the Strait of Hormuz, a critical maritime passageway that typically handles approximately 20% of global oil shipments and substantial liquefied natural gas exports. The closure has triggered dramatic increases in worldwide fuel prices and raised concerns about supply shortages.
International Energy Agency Executive Director Fatih Birol issued a grave assessment on Monday, comparing the current situation to the oil crises of the 1970s and the energy market disruption following Russia’s 2022 invasion of Ukraine. Speaking in Australia’s capital, Birol characterized the developing crisis as “two oil crises and one gas crash put all together,” suggesting the world could be facing its most severe energy emergency in decades.
The economic impact extended beyond Japan and South Korea, with Hong Kong’s Hang Seng index declining 2.5% and Taiwan’s Weighted Index dropping 2%. Meanwhile, global oil prices remained relatively stable with Brent crude trading at $112 per barrel and US-traded oil at $98.57, suggesting markets had already priced in considerable risk premiums from the prolonged conflict.
