Asian stock markets recorded sharp gains on Wednesday following news of a tentative two-week ceasefire agreement between the United States and Iran, while a blockbuster earnings forecast from Samsung Electronics further energized investor sentiment across the region.
S&P 500 futures climbed more than 2% after U.S. President Donald Trump announced a two-week delay on planned military strikes against Iran, crediting Pakistani diplomatic efforts for the breakthrough. Iran, in turn, signaled willingness to halt hostilities and expressed openness to reopening the Strait of Hormuz — a critical global oil shipping lane — pending a broader ceasefire with the U.S. and Israel. Pakistani officials confirmed both nations had reached a ceasefire agreement, with Islamabad offering to host formal peace talks later in the week.
South Korea and Japan emerged as the top regional performers, with the KOSPI and Nikkei 225 each climbing over 5%. The rally was fueled in part by strong momentum in the technology and semiconductor sectors after Samsung Electronics projected an eightfold jump in first-quarter profits, driven by explosive demand for artificial intelligence-related chips. Samsung shares surged more than 6%, while fellow chipmaker SK Hynix soared nearly 11%. Both markets also benefited from bargain buying after significant underperformance in March — the KOSPI alone shed nearly 20% that month.
Gains extended across the broader region. China's CSI 300 and Shanghai Composite rose 2.3% and 1.4%, respectively, while Hong Kong's Hang Seng advanced close to 3%. Australia's ASX 200 gained 2.5%, Singapore's Straits Times index edged up 0.9%, and Indian Nifty 50 futures jumped over 3% ahead of a key Reserve Bank of India policy meeting.
Adding to the bullish mood, Brent crude oil tumbled over 13% to around $94.97 per barrel, easing inflation concerns and reinforcing optimism across global financial markets.
