Tokyo Ditches Paris, and It's Our Savings That Take the Hit
8/10TL;DR
Japan’s retreat from French government bonds highlights a broader shift in global capital flows as rising Japanese yields, currency hedging costs and concerns over France’s fiscal position push investors toward Japanese and German debt.
KEY POINTS
Japan’s century-long reversal
In 1904-1905, Japan depended on foreign financing from London and New York to fund the war against Russia. A century later, it became one of the world’s major surplus nations, recycling export earnings into global bond markets. From 1991 to 2024, Japan was the world’s top net external creditor for 34 consecutive years, before Germany moved ahead after years of large surpluses.
How Japan became a global lender
Japan’s rise as a creditor was built on persistent trade surpluses and the ability to reinvest them abroad. After the collapse of its asset bubble in the early 1990s, Tokyo pushed rates toward zero, creating decades of ultra-cheap liquidity. That policy fed the yen carry trade, allowing large investors to borrow cheaply in Japan and buy higher-yielding assets elsewhere, especially US Treasuries and European sovereign bonds.
Why Japanese money bought French debt
For years, French OATs offered a higher return than Japanese government bonds while remaining liquid and investment grade. In a world of near-zero domestic yields, Japanese institutions could earn materially more by holding debt issued by countries running larger deficits. France was one of the beneficiaries because its bond market is deep enough to absorb large foreign inflows.
Sumitomo’s sale sent a warning
A portfolio manager at Sumitomo Mitsui said the firm had sold its entire position in French bonds and switched into German and Japanese debt. The move was small relative to giant global investors such as BlackRock, Vanguard or sovereign wealth funds, but it carried symbolic weight. It showed that when Japanese investors cut euro exposure, France can be viewed as one of the least attractive core holdings to keep.
Higher Japanese yields are changing the calculus
Japan’s bond market is no longer offering only negligible returns. The 10-year Japanese yield has climbed to levels not seen since the mid-1990s, while longer maturities have moved higher still. With domestic yields around 4.5% on some long bonds and no currency risk for Japanese investors, the extra spread offered by French or Italian debt looks less compelling, especially once hedging costs are included.
Germany gains as a defensive alternative
German Bunds have become a natural substitute for investors who still want euro exposure but with a stronger credit profile. Germany also remains a major trade partner for Japan. Even if Bund yields are lower than French yields, their perceived safety and liquidity make them more attractive in a period of portfolio repatriation and tighter scrutiny of sovereign risk.
France remains exposed to Japanese positioning
Roughly 6.6% of the foreign bonds held by Japanese investors are French. That is a significant share and reflects the size of France’s bond market. If more Japanese institutions reduce their euro holdings, France is vulnerable not because it is on the verge of default, but because in relative terms its debt can look less desirable than German debt and less convenient than newly higher-yielding Japanese paper.
A rapid jump in borrowing costs
France recently raised €6.3 billion in 10-year debt at about 4.93%, a level comparable to the early 2000s. The speed of the move worries markets: it took about 18 years for rates to fall from around 5.5% to near zero, but only about four and a half years for much of that easing to be reversed. Faster rises in yields mean a quicker deterioration in debt-servicing conditions.
A broader market signal, not just a French story
The shift is occurring alongside strains in global credit markets and a repricing of risk in equities and corporate debt. Higher yields are reducing liquidity and forcing investors to reassess crowded positions tied to growth themes such as artificial intelligence. In that setting, weaker sovereign borrowers are more likely to be sold first when foreign investors choose what to cut.
CONCLUSION
Japanese investors are not abandoning France alone, but their reallocation underscores how quickly a long period of easy financing can end. For France, the message is that relative trust in its debt is weakening just as global capital is finding safer or simpler alternatives.
