Conclusion SummaryJapan's outstanding government debt as a percentage of GDP is exceptionally high internationally, but this is thought to be due to Japan's unique methods, such as the 60-year redemption rule.Since 2013, Bank of Japan has rapidly increased the amount of its outright purchases of government bonds.In addition, since 2016, negative interest rates have been introduced, and a portion of current account deposits have been subject to negative interest rates, but this was lifted in March 2024.The rate of infl ation in Japan had been on a long-term downward trend until 2019, so monetary easing continued for a long time.As a result, Bank of Japan's share of government bond holdings reached nearly 50%.Furthermore, Bank of Japan's share of 10-year government bonds reached around 80%.As a result, general trading in the government bond secondary market has shrunk.Bank of Japan raised its policy interest rate to 0.25% in July 2024, but in the future, in addition to the burden of interest payments on the government's fi nances, Bank of Japan's own fi nancial burden will be an issue.
