三大维度看，美债抛售风险有多大？

Macro Analysis - The risk of foreign countries selling U.S. Treasuries is a concern, especially in light of recent tariff announcements by Trump, but the actual impact may be limited due to the scale of the U.S. Treasury market[1] - The total outstanding U.S. Treasuries and daily trading volume are significantly larger than the holdings of any single foreign country, indicating that no single nation can manipulate the market[1] - Historical data shows that foreign selling has less impact on Treasury yields compared to fundamental variables[1] Treasury Structure - As of March 2025, the maturity structure of U.S. Treasuries is as follows: short-term (1 year or less) at 21.5%, medium-term (1-10 years) at 51.8%, and long-term (over 10 years) at 17.2%[2] - Foreign investors hold 33.0% of U.S. Treasuries, with the largest holders being Japan (12.5%), the UK (8.6%), and China (8.5%) as of March 2025[2] Maturity and Repayment Pressure - The total maturity of U.S. Treasuries reached $12 trillion from January to May 2025, compared to $11.5 trillion in the same period last year, indicating a rolling peak in maturity pressure[3] - The U.S. government is currently at its statutory debt ceiling, limiting new issuances until Congress acts, which could increase future maturity pressure if the ceiling is raised[3] Trading Volume and Foreign Selling - The average daily trading volume of U.S. Treasuries reached $1.36 trillion as of April 2025, exceeding the holdings of any single foreign country, such as Japan, which holds approximately $1.13 trillion[6] - Historical trends show that reductions in foreign holdings, such as China's decrease from $1.3 trillion in 2015 to under $800 billion by March 2025, have not led to significant deviations in Treasury yields from fundamental trends[7] Conclusion on Foreign Selling Impact - If tariffs lead to foreign countries reducing their Treasury holdings, it is unlikely to cause sustained increases in Treasury yields due to several factors, including the vast size of the Treasury market and limited alternative reserve assets[8] - A coordinated and aggressive sell-off by multiple countries could pose a significant risk to the Treasury market and global financial stability, but this scenario is considered less likely[8]
