Rakuten Bank to Refrain From JGB Buying as More Rate Hikes Seen

Rakuten Bank Ltd. will likely halt active Japanese government bond purchases, signaling a cautious stance driven by expectations of further Bank of Japan rate hikes and an uncertain policy outlook. This decision comes despite the bank's significant deposit growth, which nearly tripled to ¥11.7 trillion ($79 billion) by June, highlighting how the evolving monetary policy landscape is influencing investment strategies among financial institutions.

Analysis

Rakuten Bank Ltd. is signaling a significant shift in its investment strategy by refraining from active purchases of Japanese government bonds (JGBs), a decision directly linked to the anticipation of further interest rate increases by the central bank. This cautious stance is particularly noteworthy given the bank's rapid balance sheet expansion, with total deposits nearly tripling over five years to reach ¥11.7 trillion ($79 billion) by the end of June. The move highlights a critical tension: while strong customer acquisition is swelling the bank's cash reserves, the uncertain monetary policy outlook is creating a disincentive to deploy this capital into traditional fixed-income assets. This hesitation from a fast-growing lender serves as a tangible indicator of broader investor sentiment, underscoring the risk of capital losses on existing bond holdings should the Bank of Japan proceed with additional rate hikes.

Key Decisions for Investors

• Investors in Japanese fixed income should view Rakuten Bank's posture as a cautionary signal regarding duration risk, as the expectation of further rate hikes could lead to capital losses on long-term JGBs.
• Monitor the investment behavior of other Japanese financial institutions, as a widespread halt in JGB purchasing could materially affect bond market dynamics and signal systemic risk aversion within the banking sector.
• For those evaluating Rakuten Bank, the strong deposit growth to ¥11.7 trillion is a fundamental positive, but this must be weighed against the near-term challenge of profitably deploying this liquidity in a rising-rate environment, making future net interest margin a critical metric to watch.
