The Bank of Japan (BoJ) recently hinted that it may slow down its pace of quantitative tightening (QT), a process of reducing the amount of government bonds it holds.
This signal came from a summary of discussions where a market expert suggested that aggressively shrinking the BoJ's balance sheet isn't urgent right now. The main reason for this cautious approach is a delicate balancing act. On one hand, Tokyo's core inflation has been below the BoJ's 2% target for four consecutive months, which reduces the pressure to tighten policy quickly. On the other hand, a different measure called "trend inflation," which filters out temporary factors, remains high at 2.8%, suggesting that underlying price pressures haven't disappeared. This tension explains why the BoJ might want to be patient with QT.
However, the more immediate concern is the stability of the Japanese government bond (JGB) market. Recently, the yields on super-long-term bonds (like 40-year bonds) have been extremely volatile, swinging sharply on news about supply and demand. Rushing to sell more bonds through aggressive QT could pour fuel on this fire, creating instability. By signaling a slower pace, the BoJ is prioritizing a calm and functioning market over a rapid reduction of its assets.
Supporting this stance is Japan's recent success in securing strong wage growth. For the third year in a row, major companies have agreed to wage hikes of over 5% in the annual Shuntō negotiations. This sustained wage growth gives the BoJ confidence that inflation can remain near its target without resorting to disruptive, fast-paced QT. It effectively allows the central bank to separate its two main tools: using QT adjustments to ensure market stability, while keeping interest rate hikes as an option to manage inflation if it re-accelerates.
This cautious approach is not new. The BoJ had already planned a gradual slowdown of its bond purchases for 2026, based on similar market fragility concerns observed in 2025. Today's message simply reinforces that long-standing strategy: normalize policy, but do it carefully and predictably, without shocking the financial system.
- Quantitative Tightening (QT): The process where a central bank reduces the size of its balance sheet by selling the government bonds it holds or letting them mature without reinvesting the proceeds. It's the opposite of quantitative easing (QE).
- JGB (Japanese Government Bond): Debt securities issued by the Japanese government to finance its spending.
- Shuntō: An annual event in Japan where labor unions negotiate with companies for wage increases for the upcoming fiscal year. Its outcome is a key indicator of wage trends.
