A conditional two-week ceasefire agreement between the United States and Iran, which includes the temporary reopening of the Strait of Hormuz, triggered a significant rally in Asian technology and semiconductor stocks on Wednesday.
The news propelled major Asian stock indices higher, with chipmakers—highly sensitive to global trade flows and energy costs—leading the market gains.
Taiwan Semiconductor Manufacturing Company (TSMC) rose 4.84%, while Semiconductor Manufacturing International Corporation (SMIC) surged more than 10%.
In Japan, semiconductor equipment manufacturer Tokyo Electron advanced 9.6%, Advantest climbed over 13%, Renesas Electronics, a key supplier to NVIDIA, jumped 12%, and Fujikura, an electrical equipment firm, gained 11.58%.
In South Korea, memory chip leader SK Hynix soared more than 15%, and Samsung Electronics increased over 9%. Samsung's share price also benefited from the company's forecast on Tuesday that first-quarter profit would surge eightfold, driven by booming artificial intelligence demand for high-bandwidth memory chips used in data centers and servers.
Although sustained strong demand from this year's AI boom has fueled soaring profits for major chipmakers, the Middle East conflict had raised serious concerns about their global supply chains, particularly regarding helium supplies.
In semiconductor manufacturing, helium is used for cooling due to its heat dissipation properties and is also an essential gas in the lithography process, a key technology for printing intricate circuits onto chips.
In recent weeks, attacks by Iran on industrial facilities in Qatar—a supplier of roughly 30% of the world's helium—along with the closure of the critical shipping route, the Strait of Hormuz, had severely tightened helium supplies.
Analysts warned that if the conflict persisted, chipmakers could eventually face production delays as helium inventories were depleted.
The ceasefire agreement announced by the U.S. on Tuesday evening, although temporary, has boosted market expectations that tensions may ease and shipping through the Strait of Hormuz could return to normal.
The agreement follows weeks of heightened tensions, during which U.S. President Donald Trump threatened to strike Iranian infrastructure unless Iran reopened the Strait of Hormuz—a passage responsible for about one-fifth of global oil shipments.
The news also caused a sharp drop in oil prices, which is expected to alleviate potential inflationary pressures across the entire semiconductor industry supply chain.
U.S. stock futures also rose during Asian trading hours, pointing to a higher opening on Wall Street.
