Japan’s finance minister, Satsuki Katayama, made an unexpected announcement on July 10, urging the country’s pension funds—including the massive Government Pension Investment Fund (GPIF)—to increase investments in Japanese assets. The statement, delivered during a routine press conference, signaled a potential shift in policy and hinted at broader cabinet support for the move. The GPIF, which manages over $1.8 trillion, currently allocates 25% of its portfolio to domestic bonds, stocks, and other local assets. Officials suggest this ratio may rise as domestic returns improve.
Policy Shift and Market Reactions
Naoya Oshikubo, chief market economist at Mitsubishi UFJ Trust and Banking Co., who took part in Funds Europe’s roundtable on Japan earlier in 2026, responded: “On the 10th of July, finance minister Katayama stated: ‘I want to pursue measures to encourage pension funds, including the GPIF, to invest more in Japanese financial assets.’ She added: ‘I intend to promote this through a new package aimed at creating a virtuous cycle of growth and asset accumulation for the public.’” Oshikubo emphasized that the government’s revised draft of “Basic Policies on Economic and Fiscal Management and Reform” now explicitly references the Bank of Japan’s independence, a shift from the Takaichi administration’s previous opposition to BOJ rate hikes, which had contributed to rising long-term interest rates and yen weakness. This change, he argued, could pause the upward trend in yields and curb further yen depreciation, creating a “triple rise” in Japanese markets driven by improved investor sentiment, yield gains, and structural reforms.
Commenting further, Masahiko Loo, senior fixed income strategist at State Street Investment Management, highlighted the government’s strategic signaling at a time when market skepticism about the Ministry of Finance’s remaining capacity for FX intervention has grown. With over $1 trillion in foreign exchange reserves, intervention remains an option, but Loo stressed that encouraging domestic institutional capital to stay invested in Japan is a more durable and structural way to support the yen. He noted that as the BOJ approaches its terminal rate and domestic yields become more attractive, banks holding roughly ¥400 trillion in excess cash are likely to deploy liquidity back into Japanese government bonds, improving demand-supply trends. A gradual reduction in structural capital outflows, he said, could also provide increasing support for the yen.
Analysts say the shift is gradual but meaningful. While pension funds typically maintain strict allocation targets, Loo pointed to the flexibility within the GPIF’s current strategic framework, which allows for modest deviations around domestic bond exposure. This flexibility, combined with the government’s emphasis on long-term growth, creates an environment where increased domestic investment could become a self-reinforcing cycle, bolstering both public finances and private sector returns.
Economic and Political Motivations
Currently, the GPIF manages its basic portfolio so that domestic bonds, foreign bonds, domestic stocks, and foreign stocks each account for 25% of the total. Although the domestic investment ratio stands at around 50%, the government appears to be moving toward increasing this ratio in the future, as expected returns on domestic bonds have risen against the backdrop of recent interest rate hikes. In response to these remarks, long-term interest rates fell and the yen strengthened.

Against the backdrop of the draft of “Basic Policies on Economic and Fiscal Management and Reform”, the Takaichi administration’s opposition to the Bank of Japan’s interest rate hikes, coupled with growing concerns over expansionary fiscal policy, had caused long-term interest rates to rise and left the market facing a situation where the yen’s depreciation showed no signs of abating.
However, with the revision of “Basic Policies on Economic and Fiscal Management and Reform” – which will include a reference to the Bank of Japan’s independence – and Katayama’s mention of the GPIF actively increasing its investments in Japanese financial assets, we expect the trends of rising long-term interest rates and yen weakness to pause. In the near term, we anticipate a ‘triple rise’ in the Japanese market.
“While any strategic asset allocation shift is likely to be gradual rather than immediate, pension funds historically have had a small deviation range around their strategic domestic bond target, suggesting there remains a modest amount of flexibility to increase domestic bond exposure over time.”
“The announcement is also a smart policy signal from the administration at a time when markets have increasingly questioned how much firepower the Ministry of Finance has left from an FX intervention perspective. With over $1trn in FX reserves, intervention remains an option, but encouraging domestic institutional capital to stay invested at home is a more durable and structural way to support the yen over time.”
“We continue to hold a constructive medium to long-term view on both JGBs and the yen. As the BOJ approaches its terminal rate and yields become more attractive, domestic investors – including banks sitting on roughly ¥400trn of excess cash – are likely to deploy a greater portion of liquidity back into JGBs, helping improve the demand-supply backdrop. A gradual reduction in structural capital outflows could also provide increasing support for the yen.”
