Intersection of Stability and Instability: Analysis of the Probability of a U.S. State Department Level 4 Travel Advisory for Taiwan

As of May 10, 2026, the U.S. Department of State maintains a 'Level 1: Exercise Normal Precautions' status for Taiwan. While this has remained unchanged since late 2025, prediction markets suggest that long-term security expectations are sharply diverging from official diplomatic indicators. Specifically, the probability of a Level 4 advisory—meaning 'Do Not Travel'—being issued by 2028 has risen to 36%, reflecting potential market concerns.

Taiwan's current travel advisory status continues at 'Level 1: Exercise Normal Precautions,' last updated on November 25, 2025. The U.S. Department of State requires only a normal level of caution for its citizens visiting Taiwan, an indicator that officially confirms the security and safety situation in Taiwan remains stable. According to the Kalshi prediction market, the probability of this advisory being upgraded to Level 4, the highest level, before July 1, 2026, is only 2.1%.

G7 member states express deep concern that the frequent and destabilizing military activities occurring around Taiwan recently are escalating tensions in the Taiwan Strait and threatening global security and prosperity.

Despite short-term stability, market participants are focusing on potential crises that could arise within the next two years. While the risk level remains very low through mid-2026, this result is based on the assumption that the current military and political balance is maintained. Since State Department travel advisories can be adjusted immediately based on rapid changes in local conditions, the low figure of 2.1% is not an absolute indicator guaranteeing long-term safety.

Steep Rise in the Risk Curve: Outlook from 2026 to 2028

1. Probability of Level 4 issuance before July 1, 2026: 2.1%
2. Probability of Level 4 issuance before January 1, 2027: 14.0%
3. Probability of Level 4 issuance before January 1, 2028: 36.0%

Data from prediction markets signals that security risks will increase non-linearly over time. The jump in risk probability from 14% in early 2027 to 36% in early 2028—more than doubling—shows that the market expects the regional security environment to reach a significant turning point within 24 months. This probabilistic outlook is interpreted as a key indicator reflecting long-term trends in geopolitical tensions surrounding the Taiwan Strait, moving beyond mere speculation.

Economic Resilience Amid Geopolitical Tensions

Despite long-term security concerns, Taiwan's real economy and tourism industry are showing robust trends as of May 2026. During the first quarter of 2026 (January–March), Taiwanese authorities approved 556 Foreign Direct Investment (FDI) projects, confirming the continued confidence of global capital. Additionally, Taiwan has set a goal of attracting 9.4 million overseas visitors for the year 2026 and is accelerating the diversification of its tourism market.

However, military movements in early 2026 serve as a reminder of the risks hidden behind this economic optimism. In late April 2026, the Chinese People's Liberation Army conducted two major military deployments in the South China Sea and Western Pacific in response to the Balikatan exercises. Specifically, the deployment of anti-ship missiles near Scarborough Shoal acted as a direct factor escalating regional military tensions and influenced the market's risk assessment.

Definition of Level 4 Advisory and Strategic Implications

The U.S. Department of State's Level 4 'Do Not Travel' advisory is the highest level of safety warning, issued only in cases of actual combat in the Taiwan Strait or extreme civil unrest. Taiwan is currently the United States' eighth-largest trading partner and a core hub of the global semiconductor supply chain. If a Level 4 advisory becomes a reality, it is expected to cause irreparable damage to the global electronics and technology industries, as well as the mandatory evacuation of non-essential personnel.

In conclusion, while Taiwan's security situation as of May 2026 officially remains within the stable category, the risk signals for 2027 and 2028 indicated by prediction markets cannot be overlooked. Investors and policymakers should closely monitor the scale of military exercises scheduled for the second half of 2026 and regular updates from the State Department. In particular, how the market's risk probability breaks through the 14% threshold as we approach January 2027 will be a key point to watch for the future security landscape.
