Taiwan is debating whether to stop shutting down its stock market every time a typhoon forces a day off work, a move that would be neutral to slightly positive for investors and businesses who currently lose trading days to storms.

• Taiwan's market closes whenever Taipei City declares a typhoon day off, a rule now facing calls for reform.
• A Taipei mayoral candidate wants the closure rule separated from the work-holiday decision, arguing the system should be clearer and more transparent.
• Regulators say the idea is still just being studied, not decided, and they're looking at how Hong Kong, Japan, and South Korea handle it.
• Hong Kong already switched to never closing for bad weather since 2024, after losing many trading days to storms.
• Keeping the old system has a real cost: past estimates put each typhoon day off at tens of billions of Taiwan dollars in lost economic activity, from stalled stock trading to missed business deadlines.

Outlook: No change is imminent — Taiwan's financial regulator is still gathering opinions and comparing other markets, while a strong typhoon this week keeps the debate alive without forcing an immediate decision.
