The TWD (New Taiwan Dollar) options market is currently pricing in a 5-8% real-world probability of a Taiwan invasion over the next 12 months, based on elevated volatility premiums in USD/TWD Non-Deliverable Forwards (NDFs). The 1Y 25-delta risk reversal is trading approximately 1.5 vols above its 5-year median, indicating a significant bid for USD calls and TWD puts. This institutional pricing represents a "~3 vol point arb" compared to retail prediction markets like Polymarket, which currently price the same tail risk event at only 3-4%.
