Taiwan unleashes its NT$500 billion stabilization fund as the Taiex sinks 20% from its peak

Taiwan's government stepped into its stock market on Friday, Nov. 6, after an AI-driven rout pushed the Taiex into a bear market. According to Focus Taiwan, the Central News Agency's English service, the management committee of the National Financial Stabilization Fund authorized an intervention to "smooth volatility in the market." It is the fund's 10th since it was created in 2000. The fund holds NT$500 billion, about US$15.26 billion.

What the Taiex did

Per Focus Taiwan's market report, the Taiex closed at 39,701.64, down 1,873.08 points or 4.51%, the fourth-largest single-day point loss in its history. It swung between 37,837.05 and 40,435.83, opening about 3,700 points lower. Turnover was NT$1.25 trillion (US$37.70 billion). Foreign institutions net sold NT$91.19 billion on the main board.

Our own chart above, built from Yahoo Finance closing data, shows a 20.3% drop from the Oct. 6 closing high. The small gap from the 20.55% figure is because Focus Taiwan measures from the intraday peak.

The TSMC problem

Focus Taiwan says Taiwan Semiconductor Manufacturing accounts for more than 40% of the market's total capitalization. It hit the 10% daily limit down intraday, then recovered to close down 4.69% at NT$2,135. The report says that rebound trimmed the index's loss by about 920 points. That concentration is the reason one chip stock can decide whether the whole market has a bad day or a terrible one. Other big names also fell: Delta Electronics lost 6.64%, Nanya Technology 4.58%, Hon Hai 4.47%, and the financial sector 3.16%, with Cathay Financial down 5.36%.

What the government did

• Premier's order. AFP, in the Taipei Times, reports Premier Cho Jung-tai told the Financial Supervisory Commission (FSC) to "closely monitor developments in both international and domestic stock markets" and stay flexible in how it stabilizes the market. He said the economy's fundamentals are sound.
• Stabilization fund. The committee cited a "continued high degree of uncertainty" in the global political and economic landscape and said the local market is highly correlated with the Philadelphia Semiconductor Index. It authorized its executive secretary to deploy money as needed. Focus Taiwan does not say how much will be spent or when. The last intervention ran from April 9, 2025 to Jan. 12, 2026, after the US announced reciprocal tariffs; earlier ones were in 2000 (twice), 2004, 2008, 2011, 2015, 2020 and 2022.
• FSC steps. Focus Taiwan says the FSC encouraged listed companies to buy back shares, reduced the amount of stock available to borrow for short selling, and raised borrowing deposits.
• Short-selling cap (single source). PANews, citing Bloomberg, reports that from Nov. 9 same-day securities-lending sales will be capped at 3% of a stock's 30-day average daily volume. We could not read the FSC's own statement, which was not on its English site when we checked, so treat that figure as reported, not confirmed.

Why it happened

Focus Taiwan says analysts tied the sell-off to fears of possible US limits on AI data center development after Democrats won both chambers of Congress. That is the same trigger behind the US and Asia moves in our global wrap, and it follows the midterm results, Alphabet's worst day on record and Meta's bond filing. No law restricting data centers exists; the fear is about expectations.

What the numbers add

Two things stand out. First, a monthly record of NT$994.32 billion in foreign selling in October preceded the crash; the exits began before the political trigger, so the stock was already being sold when the news landed. Second, Taiwan's fund has been in the market before and the last operation lasted about nine months, so an authorization is not a promise that prices will stop falling. Interventions steady trading; they do not change what chip demand will be.

Who this hits

Taiwanese electronics suppliers that sell into US data center builds, and the US contractors, electricians and equipment dealers who sell to them, are exposed to the same shift. Owners with exposure to Taiwan-dollar contracts should watch the currency and payment terms. Short sellers face higher costs from Monday, if the cap is confirmed.
