Sumitomo Mitsui calls for clear BOJ rate path to calm bond volatility

The Bank of Japan faces mounting pressure to articulate a definitive roadmap for policy normalization during its June 15-16 meeting. As 10-year government bond yields climb to three-decade highs and the yen wavers near 160 per dollar, investors are demanding greater transparency to stabilize domestic financial markets.

Arihiro Nagata, global markets chief at Sumitomo Mitsui Financial Group, argues that a decisive rate hike this month must be paired with explicit forward guidance. Nagata contends that clear communication regarding future tightening will effectively anchor long-term interest rates and curb excessive market speculation. Financial markets have already priced in nearly two hikes for the year, and Nagata suggests the central bank need only confirm it remains aligned with these expectations to soothe investor anxiety.

Beyond immediate rate adjustments, the central bank is set to evaluate its bond-buying strategy. While the current taper plan remains in place through March 2025, the bank will establish a new trajectory for fiscal 2027. Sumitomo Mitsui has proposed maintaining monthly bond purchases at approximately 2.1 trillion yen starting next April. Nagata believes this level provides a necessary floor that prevents market stress while allowing for a gradual recovery in market functioning. Despite the complications posed by rising energy costs and regional geopolitical tensions, the firm is preparing its own portfolio strategy, eyeing long-term bond acquisitions should yields approach the 3% threshold.
