The Japanese bond market is experiencing its most severe sell-off since the oil crisis, with the benchmark 10-year government bond yield at one point reaching its highest level in nearly thirty years, approaching the key 3% mark, then edging back slightly but remaining under pressure.
Investors are continuously pricing in stubborn inflation and the energy risks triggered by the Middle East situation, while the Bank of Japan has warned of the possibility of inflation overshooting. This could force interest rates to climb to 2% faster than previously expected, far above earlier peak forecasts, leading to a sharp repricing in the bond market.
The surge in yields directly tests Prime Minister Sanae Takaichi’s economic strategy, whose core logic is that growth returns can cover long-term borrowing costs. However, if interest rates remain above 3%, and real growth is only around 1%, debt financing costs will significantly exceed the currently allocated 31 trillion yen, which could constrain landmark growth investment plans.
In the face of market turbulence, the Ministry of Finance can temporarily cut bond issuance or adjust the issuance pace, and the central bank also retains emergency bond-buying tools. However, institutions believe the current surge is driven by fundamentals and the central bank may refrain from intervening for now, making these measures only short-term buffers.
Analysts point out that if the government continues to rely on subsidies and tax cuts to stimulate demand, combined with external price pressures, inflation expectations will be difficult to stabilize. The market thus doubts policymakers’ determination to curb inflation, the risk of yields rising further remains, and future focus will be on the direction of fiscal spending and further hints from the central bank on the interest rate path.
