The Bank of Japan is set to discuss a 25 basis point increase in its benchmark interest rate at a policy meeting scheduled for June 15-16, 2026, potentially raising the rate from 0.75% to 1.0% [1, 2, 3, 4]. This would be the first rate hike since December 2025 and would bring policy levels to levels not seen since 1995 [1, 3, 4].

Governor Kazuo Ueda signaled in recent speeches that rising inflation risks and current low real interest rates make rate hikes necessary. "Even though future situations remain uncertain, as long as inflation risks rise, it is necessary to seriously discuss whether to raise rates," he said [3]. Despite geopolitical uncertainties, including tensions in the Middle East, BOJ officials view inflation risks as persisting and see room for further tightening later in 2026 [1, 2, 4].

Market swap data reflects a strong expectation for a June hike, with probabilities ranging from about 77% to 90%. Higher chances exist for further rate rises in July and beyond [1, 5, 2, 4]. Japanese 10-year government bond yields hit 2.8% in May 2026, a near 30-year peak, amid expectations of policy normalization [3].

Some caution remains among experts. Former BOJ policy board member Sayuri Shirai expects the central bank may hold rates steady in June, citing inflation pressures that have not clearly intensified. "The Bank of Japan may keep rates unchanged this month, a sharp contrast to market expectations," she said [5].

Meanwhile, Mitsubishi UFJ Asset Management’s Executive Chief Fund Manager Masayuki Koguchi warned that a 25 basis point increase may be insufficient. He said, "To stop yen weakness, 25 basis points is not enough. If inflation starts to accelerate, there’s a chance that the BOJ could hike by 50 or 75 basis points at one meeting." They also raised the possibility of out-of-cycle hikes or faster moves than currently expected [6, 7].

Market participants anticipate the BOJ might slow the pace of bond purchases alongside rate increases to help reduce volatility, though official guidance remains cautious [1, 4].

The policy meeting on June 15-16 will confirm whether the Bank of Japan begins to lift rates this summer amid persistent inflation and financial market pressures [1, 2, 3, 4].
