The Bank of Japan raised its benchmark interest rate to 0.5% at its January 2026 policy meeting, the highest level since October 2008. The move marked the third rate increase since March 2024, when the BOJ ended its long-running negative interest rate policy. Governor Kazuo Ueda stated that the rate increase reflected confidence in Japan's sustained exit from deflation, with core inflation running at 2.3% year-on-year.
Why It Matters
Japan maintained negative interest rates from 2016 to 2024, making it the last major economy to abandon the unconventional policy. During this period, the BOJ effectively charged commercial banks for holding deposits, aiming to incentivise lending and stimulate growth. The gradual normalisation of rates signals that Japan's economy has finally achieved the sustained inflation that eluded it for more than two decades.
Japanese government bond yields have risen in response. The 10-year JGB yield reached 1.2% in January, up from 0.6% a year earlier. This has increased borrowing costs for the Japanese government, which carries a debt-to-GDP ratio of approximately 260%, the highest among developed nations.
Impact on the Yen and Carry Trades
The Japanese yen strengthened to approximately 148 per US dollar following the rate decision, recovering from its October 2024 low of 162. For years, Japan's near-zero interest rates made the yen a popular funding currency for "carry trades," where investors borrow cheaply in yen to invest in higher-yielding assets elsewhere. As Japanese rates rise, these trades become less profitable, which tends to support the yen's value.
The unwinding of yen carry trades in August 2024 caused significant volatility across global financial markets, with the Nikkei 225 falling 12% in a single day. The BOJ has signalled that future rate increases will be gradual to avoid a repeat of such disruption.
What It Means for Japanese Savers
For ordinary Japanese savers, higher interest rates mean that bank deposits will finally earn a meaningful return after years of near-zero rates. Major Japanese banks, including Mitsubishi UFJ and Sumitomo Mitsui, raised their deposit rates to 0.2% following the BOJ decision, the highest in over a decade. While still low by international standards, this represents a significant change for a country accustomed to earning virtually nothing on savings.
