Indices weighted toward technology stocks absorbed the heaviest pressure during a broad pullback across global equity markets, with exchanges across Asia posting the largest declines after United States inflation data came in ahead of expectations and dragged Wall Street into negative territory. Futures contracts tied to American equities pointed in different directions ahead of the opening bell.

During the opening phase of European trading, the FTSE 100 added 0.5%, reaching 10,781.63, buoyed by data showing the U.K. economy expanded at a pace that analysts had not anticipated in August. Gains of 0.3% lifted the CAC 40 to 7,899.56, while the DAX slipped by an equivalent margin to close at 25,236.07.

Trading in the Asia-Pacific region saw South Korea's Kospi gauge shed 7.6%, bringing it to a closing level of 5,554.22. Throughout the preceding month, the index lost more than 16% of its value and remained well below the 9,000 mark it had touched in June — a level tied to a wave of investor interest in artificial intelligence developments around the world. Shares in Samsung Electronics retreated 9.5%, while SK Hynix — the South Korean memory chip manufacturer — posted a steeper loss of 11.1%.

A 4.9% retreat pulled Japan's Nikkei 225 index down to a closing level of 64,425.95. Shares in SoftBank Group, a backer of OpenAI, fell by 9.3 percent. Shares in chip-equipment supplier Tokyo Electron retreated 7.8%, while memory-chip producer Kioxia Holdings shed 12.3% of its value.

Losses of 3.4% hit the Taiex in Taiwan, a market that had drawn momentum from the broader artificial intelligence rally. Shares of Taiwan Semiconductor Manufacturing Co. — the sector's dominant chipmaker, known as TSMC — slipped 2% in trading ahead of the company's upcoming earnings release.

TSMC's Thursday earnings report showed quarterly profit climbing to a record level and outpacing analyst forecasts, driven in part by what the company described as sustained demand from artificial intelligence customers. Lorraine Tan, who heads Asia equity research at Morningstar, pointed out that markets carrying a heavy technology weighting — Korea and Taiwan especially, with Japan to a lesser extent — are exposed to the risk that any moderation in AI spending growth could slow purchases of chips and related equipment, adding that a potential disconnect between investor expectations for the technology sector and actual outcomes remains the primary concern.

Trading in Hong Kong sent the Hang Seng index down by around one per cent, settling at a closing level of 24,062.72. Trading on the Shanghai Composite ended with a loss of 1.6 percent, bringing the benchmark to a closing level of 3,707.48. The S&P/ASX 200 index in Australia slipped by a tenth of a percentage point, settling at 8,719.70.

Declines on Wall Street the day before rippled through to weigh on share valuations across the market. Losses spread across Wall Street as AI-linked equities retreated, pulling the Nasdaq composite down 1.9%, while the S&P 500 gave back 1.1% and the Dow Jones Industrial Average edged lower by 0.1%. Shares of Nvidia, Broadcom, and Advanced Micro Devices — the latter commonly known as AMD — shed 3.2%, 3.1%, and 5.7% of their value, respectively.

September's consumer price index came in at 3.7% above year-earlier levels, a reading that topped analyst projections and marked an acceleration from the 3.4% pace recorded the month before. Rising bond yields and an unsettled fixed-income market have weighed on equity prices. Rates on longer-dated U.S. Treasury securities have climbed, with investors pointing to price-pressure concerns tied to an energy-market disruption stemming from the conflict involving Iran alongside an expanding federal debt load.

Pressure in the bond market looked to be letting up as Thursday's early trading got under way. Pulling back from an intraday peak above 5.32% reached on Wednesday, the 10-year U.S. Treasury yield settled at 5.09%. At some point earlier in the month, the rate had climbed to 5.35% — a level not recorded since 2002.

Crude prices retreated as unresolved conflict and lingering uncertainty over supply from the Middle East kept markets on edge. Brent crude, the contract used as a worldwide pricing reference for oil, was trading around $103.93 at the time of writing — a retreat of roughly 2% on the day — having stood nearer to $72 a barrel when armed conflict with Iran broke out in late February.

Trading brought the dollar down to 157.80 yen, a retreat from the 158.33 level it had held earlier. Against the prior session's close of $1.1157, the euro gained ground to fetch $1.1224.
