Recent disclosures regarding closed-door meetings reveal direct communications between top Japanese officials and the central bank over government bond market stability. During an internal consultation in May, Prime Minister Sanae Takaichi explicitly urged BOJ Governor Kazuo Ueda to keep the option open for expanding sovereign bond purchases should markets experience sharp volatility or face upward pressure on long-term yields, aiming to quell investor anxiety.

Governor Ueda responded cautiously to the request. He noted that the central bank must carefully gauge actual market reactions before making any intervention decisions, while stressing that it stands ready to act decisively if macroeconomic conditions warrant it. Following the meeting, Ueda only confirmed the establishment of a routine communication channel with the prime minister regarding monetary policy direction, declining to elaborate on specific operational steps. The Japanese government has also remained silent, offering no official comment on the matter.

This high-level interaction occurs at a critical juncture in Japan’s monetary policy normalization. Since July 2024, the BOJ has been systematically scaling back its government bond purchases, aiming to phase out its ultra-loose monetary framework while attempting to revive sluggish liquidity in the secondary bond market. Years of massive central bank accumulation had previously dominated the market, significantly dampening trading activity. To mitigate potential market disruptions, the BOJ announced a strategy adjustment in June, deciding to halt further reductions in its purchase pace starting next April and capping monthly acquisitions at approximately 2 trillion yen.

Market analysts widely interpret this temporary pause in the bond-buying trajectory as a de facto concession to fiscal concerns. The ruling coalition fears that continued balance sheet tightening could exacerbate risks of an upward shift in Japan’s already fragile government bond yield curve. Notably, in a research report released Tuesday, the BOJ offered additional reassurance, stating that its gradual reduction in purchase volumes has exerted only a relatively mild upward pressure on long-term yields. Collectively, these moves indicate that as the central bank pushes toward a normalized financial system, it is striving to strike a new balance between policy independence and market stability.
