Asian equities saw a marked pullback in technology names on Monday as comments from a U.S. Federal Reserve official rekindled bets on a September interest-rate increase and escalating U.S.-Iran skirmishes lifted oil prices, amplifying a risk-off tilt among investors.
South Korea’s KOSPI dropped 2.1%, the Nikkei 225 in Tokyo fell 1.7% and the broader TOPIX eased 0.7% as markets digested the twin shocks of a hawkish Fed signal and a renewed energy-price impulse.
The move followed remarks by Federal Reserve Chair Kevin Warsh that markets interpreted as a reminder the Fed faces more work if it is not confident underlying inflation is returning to the 2% target. That prompted a reassessment of the path for borrowing costs: market pricing now assigns about a 57% probability of a rate increase in September, up from roughly 35% before the Jackson Hole address. At the same time, the U.S. two-year Treasury yield climbed toward a one-month high near 4.33%.
Those developments carried particular relevance for Asian technology stocks. Many had rallied on the back of Nvidia’s recent results, which signaled continued strength in AI infrastructure demand, but investors remain alert to stretched valuations and the effect of rising financing costs. Higher short-term yields raise the discount factor applied to expected future earnings, a dynamic that tends to weigh on growth-oriented technology and semiconductor names.
U.S. futures tracked the more cautious tone: Nasdaq 100 futures were down about 0.6% and S&P 500 futures off roughly 0.4% in Asian trading hours.
South Korean technology companies experienced steep declines. SK Hynix fell 3.5% to 1.595 million won and Samsung Electronics dropped 2.5% to 250,500 won. Both stocks had previously surged on renewed confidence in AI-related memory demand following Nvidia’s results, making their sensitivity to shifts in rates and risk appetite more pronounced after the recent rebound.
On a monthly basis, SK Hynix has slipped roughly 7.2% so far this month and Samsung about 4.6%, despite the earlier Nvidia-driven recovery in August.
Japan’s domestic chip and tech names were mixed: Kioxia Holdings rose 1.1%, Sony gained 0.8% and Largan Precision climbed 3.3%, while TDK fell 2.3% and Murata Manufacturing declined 4.1%. Despite Monday’s drop, TDK remains up roughly 1% for the month. The regional pattern is uneven — LG Innotek has gained nearly 19% this month, and Foxconn is up almost 10% — underscoring divergent post-Nvidia reactions across suppliers and parts of the supply chain.
The backdrop of higher oil, attributed in market commentary to renewed U.S.-Iran clashes, added to the risk-off tone by tightening macro margins and raising near-term cost and inflation considerations for global markets.
Looking ahead, market attention is shifting toward upcoming U.S. labor-market and inflation releases. Those data points could determine whether the jump in September Fed-hike expectations that followed the Fed commentary endures or reverts, and they will be closely watched for implications on rates, funding conditions and the valuations of high-growth sectors.
Key points
- Fed comments raised September rate-hike odds to about 57% from roughly 35%, pushing short-term yields higher and pressuring growth stocks.
- South Korea’s KOSPI fell 2.1%; Japan’s Nikkei 225 dropped 1.7% and TOPIX slipped 0.7% amid the risk-off move.
- Chip names that had rallied on Nvidia’s strong outlook bore the brunt of selling, highlighting sensitivity to funding costs and valuation risk.
Risks and uncertainties
- Higher short-term interest rates could continue to increase the discount applied to future earnings, creating headwinds for technology and semiconductor stocks.
- Elevated oil prices tied to geopolitical tensions add cost and inflation upside that may exacerbate market risk aversion.
- Upcoming U.S. labor-market and inflation data present uncertainty; outcomes could either reinforce or reverse the recent rise in Fed-hike expectations.
