Asia Market Wrap 15 October: Seoul’s Circuit Breaker Trips as the Kospi Dives 7.57 Percent and Only India Rises
Nine of ten Asian indices fell on Thursday as Wednesday’s hot US inflation print reached the region’s chipmakers: Seoul’s Kospi dived 7.57 percent through a circuit breaker to a six-month low in a seventh straight decline, Tokyo’s Nikkei 225 lost 4.90 percent in a sixth, and India’s Nifty 50 rose 1.66 percent as the day’s only gain. Brent crude traded 2.32 percent below Wednesday’s settlement at 103.60 dollars a barrel on the 10:04 GMT reading, as Washington weighed easing sanctions on Russia’s shadow-fleet tankers.
A circuit breaker in Seoul as the chip selloff turns disorderly
The Kospi closed 454.59 points lower at 5,554.22, its lowest close since 7 April and a seventh consecutive decline, the longest run since September 2024 on the wire’s account. The index fell as much as 9.29 percent during the session and tripped a circuit breaker for the first time since 29 July, halting trading for twenty minutes, the tenth activation this year and the sixteenth in the index’s history, as Reuters counted it. Samsung Electronics fell 9.5 percent and SK hynix 11.1 after the Philadelphia semiconductor index dropped 4.3 percent overnight in its sixth straight decline, and the Kospi volatility gauge jumped to its highest since late August. Foreigners sold a net 3.6 trillion won of shares, about 2.68 billion dollars, with 113 of 917 traded issues higher and 789 lower, and the won ended at 1,344.6 per dollar; financial authorities held an emergency meeting and pledged a proactive response on market stability, by the wire’s account. Interest rate traders moved the other way from the equity panic: CME FedWatch odds of a Federal Reserve increase this month eased to 25 percent from 37 at Wednesday’s close, per figures carried by Reuters, as Treasury yields fell back.
Tokyo extends its slide past 65,000 while TSMC’s record quarter goes unrewarded
The Nikkei 225 fell 3,318.34 points to 64,425.95, a sixth straight decline that Reuters called the AI repricing reaching Tokyo, and the broader Topix lost 2.38 percent to 3,999.34, below the 4,000 line in a second straight fall; Bank of Japan board member Junko Koeda said the central bank should not be overly cautious about raising rates, on the wire’s account. Taipei’s Taiex lost 3.41 percent even as TSMC reported a sixth consecutive record quarterly profit, net income up 69 percent to 763.1 billion Taiwan dollars on AI demand it called extremely robust; the company said it would be prudent in planning for 2027 as consumer segments strain under rising component prices, while raising its 2026 revenue growth forecast to about 44 percent, as Reuters carried the call. Shenzhen fell 2.43 percent in a fourth straight decline and Shanghai 1.59 in a second, after a senior IMF official urged Beijing toward bigger fiscal stimulus with the economy near deflation, and Hong Kong’s Hang Seng eased 1.03 percent. Sydney’s ASX 200 slipped 0.09 percent, nearly flat, after September employment fell by 39,300 jobs, a print the wire said pressured the Australian dollar 0.3 percent lower. In Mumbai, the Nifty 50 rose 1.66 percent to 22,997.35 on the exchange’s own figure, with 41 of its 50 members higher, as Reliance Industries closed 3.44 percent higher and Bharti Airtel 3.31 on the exchange’s own closes, after the Jio Platforms IPO price band valued the unit at up to 108 billion dollars; the NIFTY IT index added 1.82 percent, and September’s merchandise trade deficit widened to 30.21 billion dollars.
Gainers: Nifty 50 (India) 22,997.35, up 1.66 percent, the only gain.

Intraday quotes at 10:04 GMT, in fixed order; snapshots, not settlements. The gold, Brent and WTI changes are against Wednesday’s settlements of 4,107.90, 106.06 and 95.09 dollars, as published in our Commodities Wrap of 14 October 2026; the silver change is against the feed’s prior settlement. Crude fell as the US weighed easing sanctions on Russia’s shadow-fleet tankers, with attacks near the Strait of Hormuz limiting the decline, and gold rose on the safety bid, both on the wire’s account.
Why it matters: The repricing that began with Wednesday’s hot CPI crossed the Pacific and concentrated exactly where the AI trade lives: Seoul’s first circuit breaker since July, Samsung down 9.5 percent, Tokyo’s sixth straight fall, and a record TSMC quarter sold into a 3.41 percent Taipei decline. Yet rate traders eased October hike odds to 25 percent as yields fell, gold caught the safety bid at 1.73 percent, and the one market insulated from the chip complex, India, rose 1.66 on a telecom listing. Australia’s soft employment print reinforced the same rate-relief impulse. The board reads as a repricing of the AI trade’s cost of capital, not of the day’s earnings.
Outlook: US producer prices land this afternoon with the EIA storage report a day late on Monday’s federal holiday, and Wall Street futures point lower, as Reuters carried it. Our Middle East wrap follows after the regional closes, the Europe wrap after the 15:30 GMT closing auctions, and the commodities and US wraps after the New York close, each measured against Wednesday’s published boards.
