• Potential Market Impact from GPIF Flow: Even within the existing Junya(81-3) 6736-1270Tanase

framework, a reallocation to the upper band of both domestic bonds and junya.tanase@jpmorgan.com

Japanese equities (both to 31%) could generate ~JPY 33.8tn of yen buying/ JPMorgan Securities Japan Co., Ltd.

foreign-currency selling—implying potential USD/JPY downside of ~15

yen, though flows are expected to be more gradual and dispersed compared to

a concentrated intervention episode.

• Timeline for Portfolio Change: Near-term allocation shifts could occur

within the existing portfolio band at any time, while a formal basic portfolio

revision is more likely at end-FY March 2027—though any mid-cycle change

would be entirely unprecedented, rendering the timeline and process highly

uncertain; key flow data to watch include the GPIF quarterly report (Aug 7th,

Nov 6th) and monthly flow release (Aug 10th), where outsized outflows vs.

estimated flow could signal a structural portfolio shift.

• Potential Follow-through from Other Japanese Investors: Meaningful

repatriation follow-through from other real money investors—particularly

lifers, who hold ~JPY 100tn in foreign securities at ~40% hedge ratio—appears

unlikely in the near term, as rising yields, elevated FX hedging costs, and a

prevailing JPY weakness view continue to incentivise maintaining foreign

asset exposure, with any sentiment improvement from GPIF-driven JGB

stability seen as insufficient to trigger immediate action.
