A hypothetical five-percentage-point shift by Japan's public pension funds from foreign bonds into Japanese government bonds would support JGBs and strengthen the yen, with smaller spillovers across US and European debt markets, according to BofA Securities. The analysis follows comments from Finance Minister Satsuki Katayama encouraging pension funds, including the Government Pension Investment Fund, to increase their exposure to Japanese financial assets, though no allocation change has been announced. Japan's four major public pension funds manage about ¥417 trillion, or $2.6 trillion, and a five-point shift would represent roughly ¥21 trillion, or $128 billion, of reallocation. That level of buying would exceed one month of gross JGB issuance and significantly surpass monthly net supply, with the strongest impact in the 10- to 20-year sector. Currency markets could see ¥21 trillion of yen buying spread over several months, an amount almost twice Japan's ¥11.7 trillion currency intervention in April and May, potentially moving USD/JPY by several yen, while the euro would face the greatest relative pressure among G10 currencies. The model implies potential sales of $67 billion in dollar assets and $42 billion in euro-denominated holdings, with US Treasury markets able to absorb about $65 billion of selling with limited disruption, though five- to 10-year asset-swap spreads may cheapen by one to two basis points. European government bonds could experience greater country-specific pressure, as potential French bond sales of about €10 billion would equal roughly 6% of the country's 2026 net supply, arriving amid existing budget and political concerns.
