Reported 6 Nov 2026 · Capital A one-minute read

Taiwan authorised a $15 billion market fund and Korea suspended a margin rule.

On November 6 Taiwan authorised its NT$500 billion stabilisation fund and cut short selling; Korea exempted brokers from a 140% collateral rule for 3 months. Caveat: no fund money has been spent yet.

Until now

Asian governments would let the AI selloff run and watch from the sidelines.

Now

They will spend public money and change market rules to stop it.

Why it matters

A stabilisation fund and a short-selling clamp are the tools governments reach for in a crisis, not a correction. Taiwan has used this fund 9 times before. The AI trade is now large enough in Taipei and Seoul that a fall in it becomes a matter for the finance ministry.

Established

Taiwan's fund committee authorised activation of NT$500 billion, about $15.26 billion.
Taiwan cut intraday short-sale lending to 3% of volume, from 30%.
Korea waived the 140% margin collateral rule for 3 months from Monday.

Not established

That any fund money has been spent. Activation is expected next week.
That the measures worked. Both markets still closed sharply lower.
That AI policy caused the fall. Officials named it; nobody proved it.

The record

Reported, not verified. Taiwan's finance ministry page carried nothing dated November 6, its Financial Supervisory Commission site returned only annual reports, Korea's Financial Services Commission listed one unrelated November 6 release, and 2 Taipei Times pages refused us. Verification event: either regulator's own November 6 release becoming readable.

Both interventions are dated Friday November 6, 2026. Taiwan's Ministry of Finance said the National Stabilization Fund's steering committee authorised activation of the fund, which holds NT$500 billion, about $15.26 billion. Activation is expected next week, and would be the 10th in its history. Premier Cho Jung-tai said he had asked regulators to watch the market and respond flexibly. Taiwan's Financial Supervisory Commission separately imposed short-selling limits effective Monday November 9: intraday securities lending for short sales falls to 3% of a stock's average daily volume over the previous 30 sessions, from 30%, and the deposit to borrow shares rises from 90% to 130% of the stock's value. It also encouraged listed companies to buy back shares. The TAIEX closed at 39,701.64, down 1,873.08 points, its 4th largest single-day point loss, after a record 3,737.67 point intraday fall. It lost 5,510 points, or 12.19%, for the week, and is 20.55% below its October 6 high of 49,968.92. Foreign investors sold a net NT$524.4 billion this month through November 6, after a record NT$994.316 billion last month. In Seoul, Finance Minister Lee Hyoung-il led an emergency meeting with Financial Services Commission chairman Lee Eog-weon, Financial Supervisory Service governor Lee Chan-jin and Bank of Korea senior deputy governor Kwon Min-soo. They agreed to waive the rule requiring securities firms to hold collateral of at least 140% of money lent to investors buying shares, for 3 months from November 9, to stop forced sales. Lee said "Our economy has never been on firmer ground", that officials would stop Korean stocks "overreacting relative to the country's economic fundamentals", and cited concerns that "AI industry regulations could tighten after the midterm elections". The Kospi closed at 5,059.69, down 324.11 points or 6.02%, after falling 8.55% at the open and triggering a circuit breaker, with an intraday high of 5,269.10. Samsung Electronics closed down 6.35% at 188,700 won, SK hynix down 10.44% at 1,132,000 won. Foreigners sold a net 2.769 trillion won, about $1.9 billion; institutions bought 1.7041 trillion won and retail investors 600.9 billion won. Not established: whether either regulator published its own release, and the size of any fund purchase.

How it got here

Nov 3
Voters in 10 United States states decide 41 data centre measures, 28 of which would limit data centres. Edition 072 carded them.
Nov 5
New York falls hard: the Nasdaq Composite closes down 5.52% at 24,315.00 and into correction, with the VIX up 69.66%. The Kospi closes down 5.28% and Taipei down 3.2%.
Nov 6 AM
The Kospi falls 8.52% at 9:03 a.m. Korean time and the Korea Exchange halts its main market for 20 minutes. Taipei falls a record 3,737.67 points intraday and TSMC opens locked limit-down. Edition 076 carded both, with the sessions still open.
Nov 6 PM
Taiwan's finance ministry authorises the NT$500 billion fund and its regulator cuts short-sale lending to 3% from 30%. Korea waives the 140% margin collateral rule for 3 months. Taipei closes down 1,873.08 points, the Kospi down 6.02%.
Nov 9
Both measures take effect. Taiwan's short-selling limits and Korea's margin waiver begin, and Taiwan expects the fund to be activated during that week.

Who has to react

Taiwan's and Korea's finance ministries, which now own the floor; TSMC, Samsung Electronics and SK hynix; the foreign investors who sold NT$524.4 billion and 2.769 trillion won; Taipei's short sellers, whose borrowing falls 90% on Monday; Japan, whose Nikkei entered a bear market this week; and the incoming United States Congress, named by both governments as the cause.

What to watch

Would strengthen itTaiwan's stabilisation fund reports actual share purchases, or either government adds a further emergency measure such as a short-selling ban, by February 28, 2027.
Would weaken itBoth measures lapse without extension and with no fund purchases, and the Kospi and TAIEX regain their November 4, 2026 levels, by June 30, 2027.
Would strengthen itTaiwan's finance ministry confirms the fund was authorised and then closed without buying shares, by March 31, 2027.

Why it weighs this much

Signal strength

CostMedium

CommitmentHigh

ReversibilityModerate

PersistenceMonths

Cost is medium: no fund money has been spent, but a 3 month margin waiver and a 90% cut in short-sale borrowing impose real costs on brokers and on market liquidity, and authorising the fund spends political capital. Commitment is high: a finance ministry statement, a regulator's rule change effective on a named date, and a cabinet-level emergency meeting in each capital cannot be walked back quietly. Reversibility is moderate, because both measures carry end dates and a fund can be authorised without ever buying. Persistence is months: Korea's waiver runs 3 months, and Taiwan's limits can be lifted once volatility falls.

The words

National Stabilization Fund: A Taiwanese government pot of NT$500 billion that buys shares to support the market. Using it is a political decision, not a market one.
Margin collateral ratio: The cushion a broker must hold against money it lends investors to buy shares. Fall below it and the broker sells, which pushes prices lower.
Securities lending for short sales: Borrowing shares in order to sell them, betting the price falls. Limiting the borrowing limits the betting.
