Introduction: A Storm Brews in the Japanese Bond Market
On December 4, 2025, the Japanese government bond market experienced unprecedented movements. The 30-year yield surged to a record high of 3.445%, the 20-year bonds returned to levels of the late last century, and the 10-year yield, a policy benchmark, rose to 1.905%, the highest since 2007.
Key Takeaways
- Escalating Expectations of Interest Rate Hikes: The market strongly anticipates the Bank of Japan raising interest rates at its upcoming meeting.
- Impact of Yield Curve Control (YCC) Policy: How this policy has provided cheap global liquidity in Japanese Yen.
- Risks of Carry Trades: How rising interest rates could lead to position liquidation and a collapse in high-risk assets.
- Impact of the Federal Reserve Meeting: How Federal Reserve policies could complicate the situation.
Yield Curve Control: The Hidden Engine of Global Liquidity
Since 2016, the Bank of Japan has artificially fixed the 10-year government bond yield, allowing global investors to borrow Yen at near-zero cost and use it for high-yield investments. This policy has created a hidden global funding channel.
Early Market Signals
The Japanese Yen interest rate swap market showed early signs of policy change, with interest rates on various maturities rising, indicating widespread expectations of a policy shift.
Impact of Interest Rate Hikes on Bondholders
Japanese insurance companies and other large institutions hold substantial amounts of long-term assets, making them particularly sensitive to rising interest rates, which could lead to significant losses.
BOJ's Delicate Communication
Bank of Japan Governor Kazuo Ueda hinted that the bank may make a policy decision at its upcoming meeting, triggering a strong market reaction.
Risks of Carry Trades
The rising cost of Yen funding could lead to the liquidation of carry positions, causing the Yen to rise and high-risk asset prices to fall.
Impact of the Federal Reserve Meeting
The Federal Reserve meeting could influence the situation. If the Fed is hawkish, it could lead to a stronger dollar and a weaker Yen, even if the Bank of Japan raises interest rates.
Conclusion: Towards a New Era
The Japanese bond market turmoil may be just the beginning of a new era in global markets, as changes in Bank of Japan policy could have a significant impact on global liquidity flows and asset prices. Investors should reassess their exposure to Yen funding and prepare for a more volatile market environment.
