Japan Debt Fears: Crisis Brewing or Managed?
2 Feb
Summary
- Japan's debt exceeds 200% of GDP amid fiscal stimulus plans.
- JGB yields spiked significantly after a string of weak debt auctions.
- Over 90% of Japanese government bonds are held domestically.

Recent volatility in Japan's $7.3 trillion government bond market has raised concerns about a potential debt crisis. The nation's debt stands at over 200% of its GDP, and upcoming fiscal stimulus plans are expected to exacerbate this situation. Investor confidence has been shaken, evidenced by recent sharp increases in JGB yields following a series of weak debt auctions over the past year.
However, several factors may prevent Japan from succumbing to a debt crisis. A significant portion, over 90%, of JGBs are held domestically, limiting the risk of capital outflow. The Bank of Japan itself holds more than half of all outstanding JGBs, a key stabilizing force. Benchmark interest rates remain relatively low at 0.75%, and a broad base of domestic investors, including banks and pension funds, reliably purchase these bonds, creating a "mutually-assured-destruction" dynamic that discourages widespread selling.
Japan also possesses substantial foreign-exchange reserves that could theoretically be used to retire debt. Furthermore, the Ministry of Finance has a history of employing tactics like currency interventions and "rate checks" to manage yields. Nevertheless, Yardeni Research warns that these advantages are not permanent, emphasizing the need for structural reforms to address underlying economic issues and long-term growth to truly ease the debt burden.
