Taiwan posts its strongest third quarter in 48 years amid an AI sell-off
Taiwan's statistics agency DGBAS estimated third-quarter growth at 14.36% year on year, against 12% expected in a Reuters poll. The same day the Taiex fell 2.49% on worries over AI spending, closing at 45,211.83.
Growth is the highest for any third quarter in 48 years and 2.94 points above the August forecast. It marks a fourth consecutive double-digit quarter, after 12.93% in the second quarter and 14.22% over the first nine months. Real investment and inventory change rose 26.36%, capital goods imports 58.5% and semiconductor equipment imports 35.66%. Private consumption grew 5.37%; DGBAS official Chiang Hsin-yi cited a recovering car market and the wealth effect of a record stock market. The agency noted that it last saw a similar run in 1986–87, over six consecutive quarters.
The market looked the other way that day. The Taiex lost 1,156.50 points; TSMC, which accounts for more than 40% of market capitalisation, fell 1.86% and made up about 360 points of the loss. Foreign institutions were net sellers of NT$112.47 billion on 30 October and NT$994.3 billion over October. Overnight, TSMC's US-listed depositary receipts fell 5.95% and the Philadelphia semiconductor index 7.20%.
The concern centres on whether cloud companies can generate enough return from AI infrastructure; weak Alphabet sales and rising Amazon spending were the trigger. Taiwan's constraint is not its growth rate but its dependence on a single source of demand. Exports, investment and wealth-driven consumption all lean on the same chain. Double-digit growth in non-electronics exports only partly eases this concentration, and the sources reviewed do not give its share.
Talay assessment
Bottom line
The growth data looks backwards and the stock market forwards: 14.36% reflects the order book, while the 7.20% semiconductor drop prices doubt about the return on spending. One sell-off does not amount to a break in demand. The real constraint is concentration, with exports, investment and consumption tied to the same cycle.
Likely effects
- Semiconductor demandUncertainWeeks
While the large cloud companies keep their spending commitments, order visibility holds; concern shows up first in valuations and only later in orders.
- Taiwanese consumptionNegative1–6 months
If the wealth effect from a record stock market reverses, part of the 5.37% rise in consumption erodes.
- Turkish investors and exportersUncertainWeeks
Global semiconductor volatility feeds into emerging-market fund flows via risk appetite; Türkiye is affected indirectly through this channel.
