Asia Markets Crater as US-Iran Tensions Ignite; Nikkei Plunges 4%

Key Takeaways

  • Asia-Pacific markets plunged on Monday, with the Nikkei 225 and KOSPI dropping over 4% following reports of explosions in Tehran and a 48-hour ultimatum from President Trump.
  • Goldman Sachs (GS) raised its 2026 Brent crude forecast to $85/bbl, assuming Strait of Hormuz flows could drop to just 5% of normal for a six-week period.
  • Elliott Investment Management has taken a multibillion-dollar stake in chip-design software maker Synopsys (SNPS), pushing for operational and financial improvements amid AI-driven chip complexity.
  • The Japanese government is set to tap ¥800 billion in budget reserves to subsidize gasoline prices as energy costs surge due to Middle Eastern disruptions.
  • South Korea's Samsung Electronics (005930.KS) saw shares slide over 4% as regional tech sentiment soured despite provisional data showing a $12.13 billion trade surplus.

Asian equity markets collapsed on Monday morning as geopolitical tensions in the Middle East reached a breaking point. The Nikkei 225 (^N225) extended its selloff to 4%, breaking below the critical 52,000 level, while South Korea’s KOSPI plunged 4.7% and Australia’s ASX 200 dropped 1.6%.

The market rout follows reports of explosions across Tehran and an airstrike on a radio station in the Iranian port city of Bandar Abbas. Investors are reacting to a 48-hour ultimatum issued by President Trump, who warned that the U.S. would "obliterate" Iranian power plants if the Strait of Hormuz is not fully reopened to global shipping.

Goldman Sachs (GS) responded to the escalation by raising its 2026 Brent crude forecast to $85/bbl. Analysts at the bank warned that a prolonged disruption could see flows through the Strait of Hormuz—a vital artery for 20% of global oil—fall to just 5% of normal levels for up to six weeks.

In the corporate sector, Elliott Investment Management has reportedly built a multibillion-dollar stake in Synopsys (SNPS). The activist investor is pushing for better execution and profitability, arguing that the company’s shares have underperformed despite its essential role in the AI-driven semiconductor boom.

Japan’s top currency diplomat, Atsushi Mimura, stated that the government is "ready to act on all fronts" against extreme currency volatility. To mitigate the domestic impact of soaring energy costs, the Japanese government plans to tap approximately ¥800 billion in budget reserves to curb rising gasoline prices.

South Korean markets faced additional pressure as Samsung Electronics (005930.KS) shares fell more than 4%. The decline came despite provisional customs data for March 1-20 showing a $12.13 billion trade surplus, as a 19.7% surge in imports highlighted the growing cost of energy and raw materials.
