JPMorgan said Japan's Government Pension Investment Fund, or GPIF, may be reconsidering its asset allocation after a sharp rise in Japanese government bond yields, which could provide further support for the yen. According to Sina Finance, strategist Ikue Saito said GPIF held an extraordinary committee meeting on August 21, the first meeting in August in seven years.
The fund concluded in March that there was no need to review its core portfolio. JPMorgan said revisiting the issue only five months later is unusual and suggests the committee may be reexamining its earlier stance.
The most likely trigger is the sharp rise in Japanese government bond yields since March, which has prompted GPIF to reassess the assumptions behind its portfolio. Any formal change to the core portfolio would require multiple steps and would likely take at least several months.
Even without changing the core portfolio, GPIF can adjust asset weights within its existing allocation range, which could increase demand for yen-denominated assets. A larger shift that raises the strategic weight of yen assets would bring sizable yen buying and could also force the market to cover short yen positions.
Monthly capital flow data due on September 8 will be the next key indicator. If foreign bond and equity flows deviate materially from expectations, it could indicate that GPIF's portfolio strategy has already changed.
