[Analysis] Possibility of Level 4 Travel Advisory for Taiwan: The 2027 Turning Point Seen by Prediction Markets

As of Friday, May 15, 2026, Taiwan is classified by the U.S. Department of State as 'Level 1: Exercise Normal Precautions.' This is the lowest risk level, reflecting current diplomatic stability. However, recent prediction markets have begun to show a clear divergence between the current stable official rating and long-term risk assessments. While the short-term probability of a 'Level 4: Do Not Travel' advisory remains low, risk probabilities are trending sharply upward starting from the 18-month mark.

While Taiwan's current security situation is very stable, the surge in market risk probabilities starting in 2027 and 2028 is a key indicator that policymakers and investors should pay attention to.

The U.S. Department of State maintains Taiwan's travel advisory at Level 1, last updated on November 25, 2025. This rating is given to the safest group of countries internationally, signifying low crime rates and stable security within Taiwan. The Canadian government's travel advisory report also notes that violent crime is rare in Taiwan, recommending caution only for petty crimes such as pickpocketing.

Market Sentiment: Expanding Risk Horizons

1. Probability of Level 4 issuance before July 1, 2026: 3.6%
2. Probability of Level 4 issuance before January 1, 2027: 15.0%
3. Probability of Level 4 issuance before January 1, 2028: 36.0%

According to prediction market data from Kalshi, the short-term outlook through mid-2026 is very stable. However, the probability rises to 15% by early 2027 and reaches 36% by early 2028. This suggests that market participants see about a one-third chance that tensions in the Taiwan Strait will escalate significantly within the next two years, leading the U.S. government to issue its highest-level travel advisory.

Criteria for Level 4 'Do Not Travel' and 2026 Cases

A Level 4 travel advisory is the highest level of warning, prohibiting U.S. citizens from traveling to the country and advising immediate evacuation. Representative cases include Chad, issued on April 30, 2026, due to landmines and kidnapping risks, and Iraq, issued on March 2, 2026, due to terrorism and armed conflict risks. Compared to Taiwan's current low crime rate, a Level 4 upgrade would be a measure that could only occur due to geopolitical conflict or military threats, rather than simple public safety issues.

Diplomatic movements between the U.S. and Taiwan have been active since early 2026. In February 2026, a U.S.-Taiwan mutual trade agreement was signed, and the U.S. House of Representatives passed the 'PROTECT Taiwan Act.' Furthermore, as of May 2026, high-level exchanges continue, including visits by U.S. Senators to Taiwan and cyber resilience workshops by the American Institute in Taiwan (AIT). However, some analyses suggest that these close moves could actually act as factors heightening long-term tensions.

Internal political friction is also cited as a risk factor. According to a May 1, 2026, report from the American Enterprise Institute (AEI), Taiwan's opposition parties, the Kuomintang (KMT) and the Taiwan People's Party (TPP), are strongly opposing the government's $40 billion defense budget proposal. Additionally, Taiwan public opinion polls have confirmed skepticism among the Taiwanese public regarding whether the U.S. would deploy military forces without conditions, raising concerns about internal cohesion.

If the travel advisory is upgraded to Level 4, the implementation of the recently signed trade agreement and the operations of the AIT would be severely impacted. Considering that Taiwan's crime risk is extremely low, as stated in Canada's travel advisory, a change in the advisory level would be an indicator purely reflecting security and military tension. This is likely to cause massive uncertainty across the economy, including the semiconductor industry in Taiwan.

In conclusion, while Taiwan is classified as a safe area to travel as of May 15, 2026, the surge in probabilities in prediction markets toward 2027 and 2028 is unusual. Observers should closely monitor the actual implementation of the PROTECT Taiwan Act and military deployments in the region. The market's warning that the current Level 1 rating could change rapidly at any time depending on geopolitical inflection points should not be overlooked.
