Tokyo, December 1, 2025 – Japan’s two-year government bond yield surged to 1.00% on Monday, marking its highest level since November 2008 and underscoring a historic shift in the world’s third-largest economy. The sharp move came after Bank of Japan Governor Kazuo Ueda delivered his clearest signal yet that the central bank is prepared to raise interest rates at its December 18-19 policy meeting.
The yield jump – the largest single-day increase in over a decade – reflects growing market conviction that Japan is finally exiting three decades of near-zero or negative interest rates. For years, these ultra-accommodative policies made the yen the funding currency of choice for the global carry trade, allowing investors to borrow cheaply in Japan and chase higher returns abroad in everything from U.S. Treasuries to emerging-market equities and cryptocurrencies.
That era now appears to be drawing to a close.
Speaking at a financial conference in Nagoya on Sunday, Governor Ueda reiterated that “upward pressure on prices and wages is broadening” and that the BOJ would “adjust the degree of monetary accommodation” if economic and price developments align with the bank’s forecast. Markets interpreted the remarks as a virtual pre-commitment to a 25 basis-point hike later this month, which would lift the policy rate from the current 0.25% to 0.50%.
The ripple effects were immediate. The Japanese yen strengthened more than 2% against the U.S. dollar in early Asian trading, touching a six-week high near 146.80. Japanese equity futures fell sharply, with the Nikkei 225 poised to open roughly 2.5% lower. Overseas, risk assets flashed red: U.S. equity futures dropped 1.8%, the Nasdaq 100 futures shed 2.2%, and Bitcoin tumbled below $94,000 as leveraged traders rushed to unwind yen-funded positions.
Analysts warn that the unwinding of the yen carry trade could trigger broader deleveraging across global markets.
“For the past fifteen years, cheap yen borrowing has been a perpetual bid under risk assets,” said Takahide Kiuchi, former BOJ board member and now executive economist at Nomura Research Institute. “A sustained rise in Japanese short-term rates forces investors to either hedge their currency exposure – which is expensive – or reduce leverage entirely. We are likely only in the early stages of that process.”
The shift carries particular significance for highly leveraged sectors. Real-estate investment trusts (REITs), technology growth stocks, and private-credit funds that relied on low-cost yen financing now face higher funding costs and potential forced sales. Emerging-market currencies that benefited from yen weakness – notably the Australian dollar, Mexican peso, and Turkish lira – all weakened sharply in overnight trading.
Within Japan itself, the prospect of higher rates is bittersweet. Households and companies have grown accustomed to borrowing costs near zero; the average new mortgage rate remains below 1.5%. A rapid normalization risks squeezing corporate profit margins and consumer spending. Yet many economists argue that escaping the low-growth, low-inflation trap requires precisely this normalization.
Prime Minister Shigeru Ishiba welcomed the development cautiously, telling reporters on Monday that “a moderate rise in interest rates reflects the strength of Japan’s economic recovery.” Wage negotiations for 2026 are expected to deliver another round of solid pay increases, potentially giving the BOJ confidence that mild tightening will not derail growth.
Global central bankers are watching closely. Federal Reserve officials have repeatedly cited the yen carry trade as a source of “external financial vulnerability” for the United States. A disorderly unwind could push U.S. borrowing costs higher and complicate the Fed’s own path toward rate cuts in 2026.
For now, market participants are pricing in roughly 70 basis points of tightening by the Bank of Japan over the next twelve months – a pace that would bring the policy rate above 1% by the end of 2026. That would still leave Japanese rates among the lowest in the developed world, but it would decisively end the era of free money that has defined global finance since the late 1990s.
Three decades after Japan first slashed rates to zero in its battle against deflation, the world’s most famous carry trade may finally be coming home to roost.
