Japan’s 10-year government bond yield surged to 1.85%, the highest level since 2008. This marks a major departure from Japan’s ultra-low interest rate policy that has been in place for decades. Experts are now warning that this shift could have far-reaching consequences for global liquidity as the world heads into 2026.
For years, Japan maintained near-zero rates while other countries tightened their monetary policies. This made the yen a preferred funding currency for carry trades, fueling liquidity in U.S. Treasuries, European bonds, and global risk assets. However, inflation in Japan has remained above the Bank of Japan’s 2% target for over three years.
Now, swap markets anticipate a potential rate hike at the Bank of Japan’s December 18-19 meeting. Prime Minister Sanae Takaichi’s recent meeting with Bank of Japan Governor Kazuo Ueda further signals support for higher rates. “The anchor is breaking,” said Shanaka Anslem Perera, an analyst, referring to Japan’s longstanding role in maintaining low global liquidity.
Japan’s rising bond yields are pushing Japanese institutions to rethink their investment strategies. With around $1.1 trillion invested in U.S. Treasuries, the change in Japan’s monetary policy could lead to reduced capital inflows into foreign markets. When domestic yields rise, investing abroad becomes less attractive, which can pull liquidity away from U.S. Treasuries, equities, and emerging markets.
Japan’s fiscal stimulus package, worth ¥21.3 trillion, is adding pressure to the bond market. Increased government spending leads to more bond issuance, further pushing up long-term yields. With the Bank of Japan scaling back its bond purchases, yields on 30-year bonds have surged to 3.40%, a modern-era high.
The rise in Japanese bond yields has implications for global liquidity. When the yen strengthens, borrowing costs rise, volatility increases, and investors often reduce exposure to riskier assets. This includes markets like cryptocurrencies, which, though not directly tied to Japan’s bond market, move with the liquidity cycle.
