Japan’s pension fund took a 5.25 trillion yen hit as rising global yields and a stronger yen cut the value of its foreign bond holdings.

Key points
- GPIF recorded a 5.25 trillion yen ($33.3 billion) loss in the September quarter, its first quarterly loss in six quarters.
- Foreign bonds fell 6.52 percent, or 5.23 trillion yen, as U.S. Treasuries and Euro bonds sold off and the yen strengthened to 157.14 per dollar.
Japan’s Government Pension Investment Fund posted a 5.25 trillion yen loss for the three months to 30 September, reversing a 24.09 trillion yen profit in the prior quarter. The loss equalled 1.6 percent of assets and was driven almost entirely by foreign bonds, which fell 6.52 percent. Total assets declined to 314.39 trillion yen from 317.76 trillion yen three months earlier.
What happened
The fund’s foreign-bond book accounted for virtually the entire quarterly loss, dropping 5.23 trillion yen. Deep selling in U.S. Treasuries and Euro bonds drove most of the decline, according to the fund’s statement. A stronger yen, which moved to 157.14 per dollar from 162.53, further reduced the yen value of overseas holdings.
Domestic bonds also contributed to the loss, falling 1.80 percent as the 10-year Japanese government bond yield climbed to 3.07 percent from 2.68 percent. Foreign equities declined 1.86 percent, while domestic equities gained 3.71 percent, or 2.88 trillion yen, providing the only offset.
What is moving yields
Rising global bond yields weighed on the fund’s overseas holdings. The 10-year JGB yield climbed to 3.07 percent from 2.68 percent over the quarter, reflecting higher term premiums and reduced expectations for further Bank of Japan accommodation. The same yield rise that lifted domestic yields also pressured prices of foreign bonds held by GPIF.
The yen’s rise from 162.53 to 157.14 per dollar compounded the price decline in foreign bonds, cutting the yen value of dollar- and euro-denominated assets even before local-currency price moves.
Why it matters
GPIF manages 314.39 trillion yen and is one of the largest cross-border buyers of U.S. Treasuries and European government bonds. A quarterly loss of this size can alter its future hedging and duration decisions, potentially reducing demand for foreign bonds at upcoming auctions. The reversal also highlights how quickly a shift in global yields and currency trends can erase prior gains for large reserve managers.
For the fiscal year to date the fund still shows an 18.84 trillion yen gain, or 6.42 percent. However, the September quarter loss marks the first negative return since the March 2025 quarter and may prompt internal reviews of overseas allocation weights.
