Major Japanese banks are urging the central bank to clarify its policy direction after a June rate hike to mitigate sharp fluctuations in the bond market.

The Japanese financial market is currently under increasing pressure, with the yield on 10-year government bonds climbing to a 30-year high, and the yen's exchange rate falling back towards the key 160 level despite large-scale intervention in the foreign exchange market. Against this backdrop, executives at Sumitomo Mitsui Financial Group, Japan's second-largest financial institution, have suggested that the Bank of Japan, after implementing its June interest rate hike, disclose a complete and clear roadmap for normalizing monetary policy, while also optimizing its subsequent tapering plan for government bond purchases to stabilize policy expectations and mitigate sharp fluctuations in the bond market.
The Middle East conflict has driven up international energy prices, further disrupting the Bank of Japan's pace of interest rate hikes. The interest rate decision and new bond-buying rules at the June policy meeting have become the core variables influencing the short-term direction of the yen and Japanese government bonds.
Arihiro Nagata, head of global markets at Sumitomo Mitsui Financial Group, said that with both the Japanese bond and currency markets currently experiencing volatility, the Bank of Japan urgently needs to provide clear policy guidance to stabilize market expectations.
Driven by multiple factors, the yield on Japanese 10-year government bonds hit a 30-year high. Despite repeated interventions by the Japanese Ministry of Finance in the exchange rate market, the yen’s depreciation trend has not been completely reversed, and it is once again approaching the key psychological level of 160 yen to the dollar.
In a related interview, Nagata Yuhiro stated that it is highly likely that the Bank of Japan will raise interest rates in June. The most important topic of the policy meeting to be held on June 15-16 will be to refine the path for the normalization of subsequent monetary policy.
He added that the more detailed the tightening roadmap disclosed by the central bank, the more room there will be for long-term government bond yields to continue rising. In his view, the central bank does not need to release excessive tightening signals; as long as its stated policy direction is basically consistent with current market pricing, it will suffice. Currently, the market has already priced in nearly two interest rate hikes this year, and some trades even anticipate that the central bank will implement more tightening operations this year.
The Bank of Japan chose to keep interest rates unchanged at its April policy meeting, but due to the continued rise in domestic inflation, it has already signaled that it will start raising interest rates in the short term.
The energy price surge caused by geopolitical conflicts in the Middle East has become a major obstacle to central bank policy-making. High crude oil prices have, on the one hand, increased Japan's imported inflation, forcing the central bank to tighten monetary policy, and on the other hand, increased energy import costs, dragging down the country's real economy and lengthening the cycle for the central bank to judge the timing and magnitude of interest rate hikes.
In addition to the interest rate decision, the June policy meeting will review the existing bond purchase reduction plan, which will continue until March of next year, and finalize the new bond purchase plan for fiscal year 2027. Industry experts generally predict that the current bond reduction framework will remain unchanged, and market attention is focused on whether the central bank will continue its existing pace of monthly bond purchase reductions in fiscal year 2027.
Yuhiro Nagata stated that Sumitomo Mitsui Financial Group has submitted optimization proposals to the Bank of Japan, advocating for a halt to further reductions in bond purchases starting next April, fixing the central bank's monthly government bond purchase quota at 2.1 trillion yen, equivalent to US$13.15 billion. This purchase volume would both prevent liquidity shortages in the bond market due to continued reductions in purchases and gradually restore the market-based pricing function of Japanese government bonds.
Regarding the institution's own investment strategy, he added that if the yield on long-term Japanese government bonds rises to around 3%, the group will opportunistically allocate medium- and long-term government bond assets. All investment operations will be carefully assessed in conjunction with the overall market supply and demand environment.
In summary, the weakness of both bonds and the currency is forcing the Bank of Japan to accelerate policy transparency. The subsequent interest rate hike in June, coupled with adjustments to the bond-buying program, will reshape the landscape of Japan's financial market in stages.
In the context of persistently high energy costs, a clear and normalized approach is the most effective tool for the Bank of Japan to resolve bond market turmoil and stabilize the yen exchange rate.
