Asian stock markets gained momentum Tuesday as oil prices retreated following US military strikes in the Middle East. Japan's Nikkei climbed 1.1% and South Korea's KOSPI jumped 2.6% in early trading, reflecting relief among energy-importing nations. The gains came after Brent crude fell 2.8% Monday to $100.21 a barrel, easing concerns about energy costs.

President Trump claimed 'numerous' nations pledged support for protecting vessels, though the UK and Germany declined to join any wider conflict. The geopolitical tensions had initially driven oil prices higher, with Brent crude rising 1.8% to $101.96 a barrel during early Tuesday trading. S&P 500 futures dipped 0.2% after the index closed 1% higher Monday.

The market reaction underscores how energy prices directly impact Asian economies that rely heavily on oil imports. The volatility in crude markets highlights the region's vulnerability to Middle East conflicts, with investors closely watching whether the situation stabilizes or escalates further.
