Bank of Japan Increases Interest Rates
18th September 2026
Today, the Bank of Japan (BOJ) raised its benchmark interest rate by 25 basis points to 1.25%, pushing borrowing costs to a new 31-year high and marking the highest interest rate level since 1995. The BOJ’s Monetary Policy Committee (MPC) decision to raise interest was passed by seven votes to two, marking the central bank’s sixth hike under the governorship of Kazuo Ueda. In a widely expected decision, the BOJ’s Policy Board voted by seven votes to two to increase interest rates, with analysts suggesting that increase comes amidst severe global and domestic economic pressure.
The move by the BOJ comes as many major central banks (apart from the Bank of England) are raising interest rates as inflation is being pushed up due to the energy crisis, which is a result of the United States/Iran conflict in the Middle East. The increase in the policy rate comes just three months after the BOJ voted to hike rates – the shortest interval between increases since 1990. It arrives at a time when US Treasury Secretary Scott Bessent has been actively pressing Japan to raise interest rates.*.
*Scott Bessent/BOJ’s interest rates – The US Treasury Secretary has been aggressively pushing the BOJ to raise interest rates to protect the US Treasury market, strengthen the Japanese Yen, and curb regional currency weakness. Indeed, with Bessent’s repeated calls starting earlier this month to Governor Ueda to hike interest rates, money markets had almost fully priced in the chance of a rate increase at the September policy meeting.
After the policy meeting, Governor Ueda noted that underlying inflation is approaching 2.00%, the banks focus had shifted from pushing prices up to target to guarding against inflation overshoot. He was quoted as saying, “if risks of underlying inflation overshooting 2.00% materialise, that could have a negative impact on Japan’s economy”, and in his strongest remark to date on the central bank’s resolve to combat price pressure through continued rate hikes It’s important to stabilise underlying inflation at 2.00%. Our policy phase has changed”.
The Governor went on to stress that back-to-back rate hikes of 50 basis points would not be ruled out, but stressed that the BOJ did not want to be forced into large moves that might unsettle financial markets, so the bank would move pre-emptively. Experts suggest that the Governor is keeping his options open to include further increases in interest rates, whilst keeping a close eye on the state of inflation in order for it to be stabilised. BOJ officials noted that economic and price developments are moving in line with its baseline forecast, however, there is a risk of underlying inflation moving away from its 2.00% target.
As for the future, some analysts expect the central bank to lift interest rates to 1.50% by the close of business 31st March 2027 and to 1.74% by the close of Q2 2027. Experts advise that Japan is heavily dependent on energy imports purchasing circa 85% – to 90% of its total energy needs, and if the Middle East conflict carries on into 2027, the interest rates for 2027 predicted above may well turn out to be on the conservative side.
