Asian technology stocks fell sharply on Monday as mounting doubts over artificial intelligence valuations, rising bond yields, and surging energy costs converged ahead of high-stakes central bank meetings, according to a market report. South Korea's KOSPI dropped 3.1% and Japan's Nikkei 225 slipped 1.1% in response to the broader selloff.
This downturn shows growing investor anxiety regarding the sustainability of multi-year AI capital expenditures, shifting away from the previous quarters of uninterrupted sector gains.
"Dario is right," said Elon Musk, Chief Executive of xAI, in a statement supporting calls to moderate the pace of advanced model development.
Semiconductor Losses and Industry Pushback
South Korean memory-chip giants absorbed the heaviest losses due to their direct exposure to high-bandwidth memory used in AI processors. SK Hynix fell 4.3% while Samsung Electronics dropped 2.5% during Monday's session.
The pressure on hardware suppliers follows public statements from Anthropic CEO Dario Amodei, who urged a deceleration in building increasingly powerful AI models on safety grounds. OpenAI Chief Executive Sam Altman backed the proposal, while U.S. President Donald Trump downplayed the warnings as firms continue to compete aggressively against Chinese rivals.
Macro Pressures From Energy and Yields
Adding to the technology sector's losses, global energy markets experienced disruption as oil prices surged past $100 per barrel following renewed attacks on Saudi energy infrastructure and Gulf shipping lanes. Higher crude prices have reignited inflation fears just as the U.S. Federal Reserve and the Bank of Japan prepare to announce their respective monetary policy decisions.
Rising benchmark bond yields alongside expensive energy costs have tightened financial conditions globally. Analysts note that capital-intensive sectors like technology are particularly sensitive to higher discount rates applied to future earnings.
What Is at Stake for Global Markets
The simultaneous pressure on AI infrastructure valuations and energy supplies places central bankers in a difficult position as they weigh economic growth against sticky price pressures. With major Asian manufacturers leading the hardware supply chain for global tech firms, regional equity movements serve as an early indicator of shifting sentiment across international risk assets.
