TOKYO — The Bank of Japan will signal further interest rate increases at its July 30 policy meeting, sources close to the central bank said. Core consumer prices rose 2.8 percent year-over-year in June, exceeding market expectations of 2.6 percent.
The reading marks the 18th consecutive month core CPI has held at or above the BoJ's 2 percent target. The central bank ended its negative interest rate policy in March, raising the policy rate to 0.1 percent — its first hike in 17 years.
The BoJ's policy board, led by Governor Kazuo Ueda, will discuss updated inflation projections. Analysts widely expect the bank to raise its fiscal year 2026 core CPI forecast from 1.9 percent to above 2.2 percent, providing the rationale for additional tightening.
Japanese Government Bond yields rose across the curve following the data. The 10-year JGB yield climbed five basis points to 1.12 percent, its highest level since August 2013. The two-year JGB yield increased three basis points to 0.28 percent.
The Japanese yen strengthened against the U.S. dollar, trading at 155.20 yen per dollar, up 0.6 percent on the day, as investors unwound carry trades that had profited from the wide interest rate differential between Japan and other major economies.
Bond market participants are reducing duration exposure as the yield curve steepens with BoJ normalization underway. Fund managers are adjusting portfolios that had benefited from suppressed JGB yields under the bank's yield curve control program.
Domestic corporate bond spreads over JGBs are tightening, reflecting improved economic sentiment and reduced credit risk. The average spread for investment-grade corporate bonds with five-year maturities compressed by two basis points this week.
Energy costs and imported inflation continue to drive price pressures. Global crude oil prices near $82 a barrel are lifting input costs for Japanese businesses, a dynamic compounded by yen weakness over the past year.
Some economists warn that aggressive tightening could dampen Japan's fragile economic recovery. Manufacturers including Toyota and Sony face higher borrowing costs and potential export headwinds from a stronger yen.
A 25-basis-point hike to 0.35 percent is priced in for the September meeting. Markets will watch Governor Ueda's post-decision press conference July 30 for guidance on the pace of future increases.
Major Japanese banks saw their shares rise on the news. Mitsubishi UFJ Financial Group gained 1.8 percent and Sumitomo Mitsui Financial Group rose 1.5 percent, as higher rates improve net interest income.
The moves reflect the BoJ's conviction that inflation is now demand-driven and durable, not merely cost-push — a judgment that has been building across 18 months of above-target readings.
