Japanese financial institutions have begun raising interest rates on term and savings deposits in response to shifts in Bank of Japan monetary policy.

Initially, specific institutions such as Kitau Bank and Nomura Securities announced rate increases for various deposit products to align with market trends. Nomura Trust Bank, for instance, raised ordinary savings rates to 0.40% and offered term-deposit rates reaching up to 1.00% for three-year periods. As the Bank of Japan raised its policy interest rate to 1.0%, with further increases anticipated, the trend expanded to regional banks. In the Hokuriku region, banks across Toyama, Ishikawa, and Fukui prefectures have standardized ordinary deposit rates and engaged in competition through special high-interest campaigns to secure deposits and fund capital investments.

However, the transition to a higher-interest environment has created significant financial pressure for Japanese shinkin banks (credit unions). For the fiscal year ending March 2026, 17 shinkin banks nationwide reported net losses. While core business profits from lending and fees remained steady, these institutions were hit by unrealized losses on government and local government bonds, estimated to have reached 3 trillion yen. Tajima Shinkin Bank, among others, reported significant losses due to the rapid rise in long-term interest rates.

Market volatility has intensified as the 10-year government bond yield reached a nearly 30-year high of 3% on September 1, 2026. This surge is attributed to expectations of interest rate hikes by both the Bank of Japan and the U.S. Federal Reserve, alongside global inflationary pressures from rising oil prices. Additionally, concerns regarding the fiscal sustainability of Prime Minister Sanae Takaichi’s administration and her expansive spending plans have fueled market movement. In response, Prime Minister Takaichi emphasized the government's commitment to balancing economic strength with fiscal responsibility.
