Asian stock markets experienced a sharp decline on Friday as escalating tensions between the US and Iran, combined with new tariffs announced by US President Donald Trump, dampened investor sentiment. According to FX Street, these developments reduced appetite for riskier assets across the region.

Japan’s Nikkei N225 dropped nearly 3%, while South Korea’s KOSPI underperformed broader markets with a decline exceeding 4.5%, FX Street reported. The sell-off reflects growing concerns over geopolitical risks and trade uncertainties weighing on market confidence.

For Japanese investors, this downturn highlights the sensitivity of regional equities to global political events and US trade policies, underlining the importance of monitoring external factors in portfolio management.
