Did Japanese capital outflows help spread low bond yields worldwide?
Core argument: Japan became the world's largest creditor nation by 2019, with net foreign assets exceeding $3tn, after decades of low domestic interest rates pushed Japanese investors to seek higher returns abroad.
Japan's international investment position has evolved significantly over time, with its rock-bottom bond yields influencing global financial markets. In the 1990s, Japan's economic stagnation led to a prolonged period of low interest rates, which in turn caused Japanese investors to seek higher returns abroad, increasing their foreign asset holdings. By 2019, Japan had become the world's largest creditor nation, with net foreign assets exceeding $3tn. This shift in investment strategy contributed to the global spread of low bond yields as Japanese capital flowed into foreign markets, driving down yields in Europe and the US. The Bank of Japan's aggressive monetary policy, including negative interest rates and quantitative easing, further reinforced this trend, prompting other central banks to adopt similar measures. Consequently, Japan's international investment position has not only reshaped its own economy but also exerted a profound influence on global financial dynamics.
