Japan's Debt Strategy and Global Markets at Risk from Rising JGB Yields

Japan's massive debt load of ¥1.3438 quadrillion is increasingly exposed to rising Japanese government bond (JGB) yields, which are putting pressure on its fiscal strategy and global markets.

The higher rates may support the yen but raise refinancing costs for banks, insurers, and finances. A stronger yen could also unwind carry trades, forcing investors to sell foreign bonds, equities, and crypto.

The Bank of Japan's vast holdings in government securities are reaching ¥518.2 trillion, with central government debt at ¥1.3438 quadrillion. Rising JGB yields may strengthen the yen but increase refinancing costs across one of the world's largest sovereign debt markets.

Japan's effort to support the yen while containing borrowing costs is exposing a policy balance with consequences beyond its domestic economy. The strain reflects three decades of cheap money following the collapse of the country's property and equity bubble, which reduced financing costs but expanded government debt to historic levels.
