Japan JGB Yields Tumble After Finance Minister Urges Pension Funds to Buy Domestic

Japan's bond market experienced historic volatility this week. The 10-year JGB yield dropped 16 basis points on Friday to 2.71%, its largest single-day decline since April 2025, after having risen to 2.90% the previous day—a level not seen in 30 years. The 30-year JGB yield also fell sharply, declining 13 basis points to 3.87%, its steepest drop since January 21.

The moves followed comments from Japan's Finance Minister, who stated the government wants to encourage pension funds, including the $1.8 trillion Government Pension Investment Fund (GPIF), to increase investment in domestic assets. If implemented, this could shift allocations away from overseas securities and toward Japanese government bonds, easing pressure on the domestic debt market.

Such a shift would also likely support the yen by reducing capital outflows. Market participants expect continued high volatility in both Japan's bond and currency markets in the near term.
