Santander: GPIF Can Dump $62 Billion in U.S. Treasuries Without Changing Policy
nashnova research
Santander analysts say Japan's Government Pension Investment Fund can sell up to $62 billion in U.S. Treasuries within its existing mandate — meaning the divestment risk to the Treasury market may arrive faster, and more quietly, than expected.
Where does the $62 billion figure come from?
GPIF manages roughly $2 trillion and targets 25% in foreign bonds, with a policy band of ±5 percentage points.
This means → fund managers can cut foreign-bond holdings from 25% to 20% with no formal approval — that gap is the $62 billion.
In plain terms = the rulebook already has enough slack; no rule change needed, the money can move.
Why does this matter right now?
Japan's 10-year government bond yield hit 3% last week, the highest since 1996, making domestic bonds far more attractive.
Santander's team notes that if the Bank of Japan succeeds in reversing yen weakness through consecutive rate hikes, GPIF's incentive to cut foreign bonds grows stronger.
This reflects a deeper shift: rising domestic rates are fundamentally repricing the case for Japanese institutions to hold overseas assets.
Has GPIF already started moving?
Last month GPIF's board held an unusual meeting, sparking widespread speculation about its foreign-bond strategy.
Japan's Health Minister Kazuki Uwabe said officials are still weighing whether a formal allocation review is needed — no decision has been made.
This means → the signal is out, but the decision is not — the market is in a "reading-the-tea-leaves" phase.
What does this mean for the Treasury market?
Japan is the largest foreign holder of U.S. Treasuries, with $1.1 trillion on the books.
Santander modeled two scenarios: GPIF cuts foreign bonds to 20%, or changes how it tracks the FTSE World Government Bond Index — neither requires a policy change.
In plain terms = the world's biggest foreign buyer holds a hand it can play without asking permission — and that alone is a risk factor for Treasuries.
