The End of Carry Trade

For more than three decades the yen carry trade stood as one of the most reliable and influential arbitrage strategies in global finance. Investors borrowed Japanese yen at near-zero or negative real interest rates, thanks to the Bank of Japan’s prolonged ultra-loose policy, then deployed that funding into higher-yielding assets across the world: U.S. Treasuries, global equities, emerging-market bonds, Australian dollars, and, in later years, even cryptocurrencies. The trade delivered returns from the interest-rate differential, often amplified by modest currency stability or asset appreciation. At its height in 2021–2022, the outstanding yen-funded positions were estimated between $1 trillion and $1.5 trillion, with broader structured flows potentially reaching $15–20 trillion. By February 2026, however, this once-dominant mechanism has effectively ceased to exist as a scalable, low-risk strategy. The combination of sustained BOJ rate hikes and large-scale repatriation of Japanese overseas capital has destroyed the economic foundation on which the carry trade rested.

The decisive blow came from the Bank of Japan’s policy normalisation. In December 2025 the BOJ raised its benchmark short-term rate by 25 basis points to 0.75 percent, the highest level since 1995. The decision was unanimous and reflected four consecutive years of core inflation above the 2 percent target, with the 2025 average at 2.4 percent. By February 9, 2026 the rate remained at 0.75 percent, but forward guidance and market pricing pointed to additional increases, with consensus forecasts clustering around 1.0 percent by mid-2026 and 1.25 percent by the end of 2027. At the same time, Japanese government bond yields rose sharply. The 10-year JGB yield reached 2.29 percent in late January 2026, up from roughly 1.0 percent a year earlier and the highest reading since 2007. Higher funding costs in yen directly eliminated the trade’s core profitability. When borrowing was effectively free or negative in real terms, the spread to U.S. Treasuries (yielding 4.2 percent) or other global assets was generous. Once Japanese short-term rates climbed to 0.75 percent and long-end yields approached 2.3 percent, the after-hedging carry narrowed to levels that no longer compensated for volatility, margin requirements, or currency risk.

Repatriation of Japanese capital accelerated the collapse. Japan holds between $5 trillion and $6 trillion in overseas assets, of which approximately $5.48 trillion is held in securities. Roughly half sits in bonds, predominantly government debt, and the other half in equities. Of that total, about $3 trillion is invested in the United States, making Japan the single largest foreign holder of U.S. Treasuries. As domestic yields rose, Japanese institutional investors, including life insurers, pension funds, and banks, began redirecting capital homeward. In 2025 Japanese investors recorded net sales of ¥374 billion in foreign bonds, a clear reversal of the multi-year inflow pattern that had previously tripled in scale annually. Higher JGB yields made holding yen-denominated debt more attractive than parking funds abroad at lower risk-adjusted returns. This shift strengthened the yen, which appreciated about 1 percent against the dollar in the first weeks of 2026 and traded at 156.10 (February 9). A rising funding currency inflicts immediate mark-to-market losses on carry positions because borrowers must repay loans in an appreciating yen. Market commentary in early 2026 also referenced preparations by Japanese authorities to sell up to $600 billion in U.S. equities and exchange-traded funds if needed to defend the currency, adding further downward pressure on global risk assets and reinforcing the unwind.

The numbers tell a clear story of contraction. By late 2024, following the initial BOJ tightening steps, roughly 50 to 60 percent of yen carry positions had already been liquidated. The December 2025 rate increase triggered the final phase. Remaining yen-funded trades were estimated at $261 billion to $500 billion, a fraction of earlier peaks. Speculative futures positioning reversed sharply, reflecting forced exits. Global equity momentum stocks, frequently financed through yen borrowing, experienced outsized selling pressure. The August 2024 volatility spike, which erased $6.4 trillion in global market value, served as an early warning of what a more complete unwind could produce.

We consider the yen carry trade’s era definitively over. The evidence is concrete and arithmetic rather than interpretive. Japanese short-term rates at 0.75 percent, with credible expectations of 1.0–1.25 percent within eighteen months, have turned real borrowing costs positive in forward terms and compressed yield spreads to U.S. Treasuries below sustainable levels after hedging and volatility adjustments. Repatriation flows, already visible in 2025 net foreign-bond sales and projected to involve several trillion dollars over the next five to ten years, have materially reduced the pool of cheap yen funding. The yen’s move to 156, still undervalued by historical metrics but appreciating steadily, guarantees foreign-exchange losses on any remaining leveraged positions. Japan’s domestic imperatives, a debt-to-GDP ratio between 230 and 377 percent and persistent import-driven inflation at 2.1 percent, make sustained normalisation unavoidable. Post-crisis regulations already curtailed naked FX leverage, leaving only a shadow of the pre-2008 trade. When funding is no longer structurally cheap and the currency of denomination is no longer structurally weak, the mathematical edge disappears. Portfolios still exposed to residual carry dynamics face elevated tail risk from forced deleveraging and liquidity evaporation. Those that adapt by rotating into yen-hedged or domestically oriented assets will be better positioned in an environment of tighter global liquidity and structurally higher volatility. The carry trade as we knew it is not merely subdued; it is finished.

The accelerating repatriation of Japanese capital is the clearest empirical confirmation that the liberal economic narrative of unstoppable globalisation has reached its terminal point. Japan, which from the 1980s onward acted as one of the principal engines of that globalisation, flooding the world with cheap capital, suppressing global yields, and enabling the expansion of dollar-denominated debt, has now reversed course. The country that once epitomised the “end of history” and the triumph of liberal democratic capitalism is, through deliberate policy choices, withdrawing from its role as global liquidity provider. This marks the definitive closure of Francis Fukuyama’s “Last Man” moment: the ideological and financial architecture that sustained unipolar financial dominance is being dismantled from within one of its former pillars. The world is visibly shifting toward a multipolar paradigm in which major economies increasingly prioritise domestic stability, capital retention, and sovereign control over financial flows. Most critically, when Japan begins to actively repatriate capital and assets on a large scale, potentially several trillion dollars over the coming decade, the consequences for the European Union could potentially be dramatic.

The death of the yen carry trade represents a profound symbol of transformation: Japan, one of the greatest pioneers and enablers of post-war globalisation through decades of ultra-loose monetary policy that exported cheap liquidity worldwide, is now decisively shifting course. By normalising interest rates, allowing JGB yields to rise, and effectively ending the era of near-zero or negative rates that fueled massive cross-border capital flows, Japan is reclaiming domestic priorities amid persistent inflation, demographic pressures, and fiscal realities. This marks a clear signpost toward de-globalisation in finance, where capital increasingly stays closer to home rather than freely circulating in search of yield differentials. It accelerates the emergence of a multipolar world economic order, characterised by divergent monetary policies, fragmented liquidity pools, greater regional self-reliance, and reduced dependence on any single nation’s “free” funding mechanisms. In this evolving landscape, the seamless, leverage-amplified integration of the past gives way to a more cautious, bordered, and multipolar framework, where major economies like Japan assert greater autonomy, contributing to a broader reordering of global economic power dynamics and risk distribution.
