As of 9:35 AM IST, Friday 30 October 2026. Asian market levels are intraday snapshots from the sources cited and will change before the close.
Asian stock markets fell sharply on Friday as disappointing results from US tech giants revived fears about the cost of the AI boom. South Korea's Kospi dropped more than 5%, enough to trigger a trading curb, and Japan's Nikkei lost nearly 3%. In Tokyo, the Bank of Japan kept rates on hold but took a notable step towards its next hike. A day earlier, the European Central Bank also held rates, and Christine Lagarde's departure date was announced.
Asia: chip stocks take the hit
| Index | Move | Level |

| Kospi (South Korea) | -5.64% | 5,602.59 |
| Nikkei 225 (Japan) | -2.81% | 62,843.53 |
| Shanghai Composite | -0.76% | 3,623.64 |

The Korea Exchange suspended program sell orders for five minutes from 10:04:55 a.m. local time after Kospi 200 futures fell more than 5%. It was the first sell-side "sidecar" in 11 trading sessions, The Herald Business reported. Foreign investors and institutions were net sellers, while individual investors were the only net buyers. Samsung Electronics fell about 5% and SK hynix about 8%.
In Japan, chip-equipment and AI-linked names were hit hard. Investing.com reported that Advantest fell about 7%, Lasertec about 13%, Kioxia nearly 9% and SoftBank Group more than 6%. Nasdaq 100 futures were down more than 2%.
What triggered the sell-off
Overnight, Amazon missed revenue and profit estimates, reported negative trailing free cash flow of $42.4 billion and said it would spend more in 2027. Intel gave a weak fourth-quarter outlook. Both stocks fell sharply after hours. That came on top of Alphabet's cash-flow worries earlier in the week. Wall Street closed lower on Thursday 29 October:
- S&P 500: -0.30% at 7,720.39
- Dow Jones: -0.25% at 52,342.56
- Nasdaq Composite: -1.38% at 26,184.72
- Russell 2000: +1.01%
US data released the same day showed third-quarter GDP growth of 3.4% annualised, and September PCE inflation of 3.6% year on year (3.1% core), according to PrimerIQ's market wrap. The 10-year Treasury yield ended near 4.99%.
Bank of Japan holds at 1.25%, but edges towards a hike
- Decision: the policy rate stays at 1.25%, the highest since 1995, on an 8-1 vote. Board member Hajime Takata dissented in favour of a rise to 1.5%.
- Key shift: the BOJ judged underlying inflation to be "generally consistent" with its 2% target, the first such assessment since 2013.
- Forecasts: core inflation for fiscal 2027 was raised to 2.6% from 2.4%, and the core-core measure to 2.7% from 2.6%.
- Data: Tokyo's October core CPI rose 2.6% year on year, in line with expectations.
- What's next: all 16 economists in a CNBC survey expect the BOJ to be setting up a hike in December or January. That is a forecast, not a commitment.
ECB holds at 2.5%; Lagarde to step down in February
On Thursday the ECB unanimously kept its deposit rate at 2.5%, following its hike in September. Euro-area inflation is running at 3.8%, the highest since September 2023, driven by energy inflation of 18.8%. "We are not seeing second round effects," Lagarde said, as reported by CNBC. Markets priced about a 67% chance of a December hike, according to LSEG data. Deutsche Bank's Mark Wall expects one more increase to 2.75% in December, and UBS's Dean Turner called the decision a "hawkish pause."
Separately, the ECB said Lagarde will step down as president on 7 February 2027. Her successor will be appointed by the European Council. No successor had been named as of this writing.
What to watch
- Whether the Kospi and Nikkei recover any ground before the close, and how US futures open.
- Further big-tech reactions as US trading resumes on Friday.
- BOJ Governor Kazuo Ueda's post-meeting press conference for hints on December.
