Japan’s long-standing era of ultra-low interest rates is officially shifting as major commercial banks raise both deposit and loan rates following a key monetary policy adjustment by the Bank of Japan, according to the Nihon Keizai Shimbun. The central bank’s decision to push its benchmark interest rate to roughly 1.25% has triggered widespread financial adjustments across the country, creating distinct economic dividing lines between cash-rich older generations and younger borrowers.
Major Banks Raise Ordinary Deposit Rates to 0.5 Percent
Japan’s three largest financial institutions—Mitsubishi UFJ Bank, Sumitomo Mitsui Banking Corporation, and Mizuho Bank—announced that they are raising their ordinary deposit rates from 0.4% to 0.5%. According to reporting from the Nihon Keizai Shimbun, this adjustment takes effect on November 2, marking the highest ordinary deposit rate recorded in Japan since August 1992. For savers accustomed to negligible returns on cash deposits for over three decades, the shift introduces meaningful interest income for the first time in a generation.
Variable Mortgage Rates Increase Borrowing Costs for Younger Households
While savers stand to benefit, borrowers face immediate cost increases as commercial lenders adjust their prime rates upward. Mitsubishi UFJ Bank and Mizuho Bank confirmed they are raising their short-term prime rates—which serve as the benchmark for variable-rate mortgages—from 2.375% to 2.625%. According to projections cited by Mizuho Research & Technologies, the overall rate hikes will generate roughly 400 billion yen (approximately 3 trillion 500 billion won) in net interest gains for Japanese households annually, but the distribution of those gains is heavily skewed by age.
Generational Divide Grows Between Older Savers and Younger Borrowers
Financial impact analyses show that households aged 60 and older will capture the lion’s share of the increased interest income. Data from Mizuho indicates that households headed by individuals in their 60s and 70s will gain an average of about 2만엔 per year. Conversely, younger demographics face rising debt servicing expenses. Households under 29 are projected to see annual expenses climb by roughly 2만2000엔, while those in their 30s face average increases of about 2만3000엔 driven primarily by variable-rate housing loans.
According to MFS, the operator of the Japanese mortgage comparison service MoGECheck, a standard 50 million yen mortgage with a 35-year term at an initial 1.2% rate experiences a monthly repayment increase of about 6,000 yen for every 0.25 percentage point rise in interest rates. Beyond retail borrowers, corporate borrowers face tighter financial conditions. Research firm Tokyo Shoko Research estimates that the higher policy rate will reduce the average ordinary profit of small and medium-sized enterprises by 1.75% compared to the baseline set in December, adding operational pressure to businesses reliant on floating-rate commercial debt.
