TAIEX tumbles 3.59% as NT dollar falls
The TAIEX fell 3.59% (1,612.6 points) to 43,307.54, its seventh-largest single-day point loss, due to a global tech sell-off and foreign fund withdrawals. The NT dollar hit an 18-month low against the USD. TSMC's ADRs dropped 15.68% over the past month, contributing to the pressure. Foreign investors sold NT$107.31 billion, while the NT dollar fell NT$0.168 to NT$32.760. Analysts expect further depreciation pressure on the NT dollar.
How this was made

The 30-second read
Why it matters
The key tradable linkage is the continued foreign outflow narrative plus NT dollar depreciation pressure, which can sustain risk-off pressure on Taiwan’s tech complex and ADR-linked names.
Market read
Traders get a near-term risk signal for Taiwan tech exposure through FX weakness and continued foreign selling, with TSMC ADRs cited as a direct read-through.
What to watch
FX moves may be amplified by positioning and hedging flows; if foreign selling slows, the NT dollar could stabilize even without a near-term tech rebound.
Background
Taiwanese stocks fell 3.59% and the NT dollar hit a more than 18-month low as global technology sell-off and accelerating foreign withdrawals weighed on local markets.
Ticker impact
The article links Taiwan’s TAIEX weakness to TSMC ADR losses, citing TSMC’s ADRs down 15.68% as pressure spreads to Taiwan’s tech-heavy index.
Likely further pressure as markets price continued foreign outflows and NT dollar depreciation risk.
The piece directly attributes index pressure to TSMC ADR declines and frames ongoing FX and foreign-capital outflows as not yet stabilizing.
Market effects
Reinforces a risk-off rotation away from AI-linked semiconductors amid concerns about AI capex returns and free-cash-flow squeeze.
Highlights Taiwan’s equity and FX sensitivity to US tech moves and foreign fund withdrawals, with NT dollar weakness feeding equity stress.
Signals spillover from US chip rout and US political uncertainty into Asia tech and FX, supporting a broader de-risking bias.
Counterpoint
