BOJ Holds Rates At 1.0%, Future Policy Tightening Likely

The BOJ voted with 8:1 majority to keep policy rate unchanged at 1.0%, in line with the expectations. Japan ended negative interest rates in March 2024 and since then, has increased interest rate by a cumulative 110 bps, by following a measured and cautious approach. The BoJ reiterated that it will continue to raise rates in response to the developments in the economic activity, prices as well as financial conditions.

Growth Outlook Remains Intact While Upside Inflation Risks Persist

The BoJ marginally upgraded its growth projections, expecting real GDP growth of 0.6% in 2026 and 0.8% in 2027, supported by resilient domestic demand, government measures and robust AI-related global demand.

On inflation, although temporary government energy subsidies lowered the FY26 CPI forecast, the Bank expects inflation to rise above 2% in the second half of FY26, with full FY26 forecast set at 2.5% and 2027 at 2.4%. Persistent yen weakness, higher energy prices, rising AI-related semiconductor prices and stronger wage growth could keep inflationary pressures elevated, increasing the likelihood of further policy tightening.

Interest Rate Differential Continue to Drive Yen Weakness

Persistent yen weakness remains a key challenge for policymakers in Japan. Although the US–Japan 10-year yield spread has narrowed by 26 bps since the start of the year, it remains elevated at 185 bps, continuing to favour capital flows into US assets and keeping the yen under pressure. The government's decision to intervene in the FX market ahead of the BoJ policy meeting highlights increasing concern over the inflationary impact of a weaker currency.

Market Reaction

Markets reacted positively to the BoJ's policy decision. The Nikkei 225 rallied 4.0%, while the yen appreciated after the government's FX intervention. Japanese government bond yields remained broadly stable.

Ionic Wealth View

The BoJ to remain on a policy tightening path, although its measured and cautious approach continue to put pressure on yen. While inflation is expected to edge higher in the second half of FY26, the full year estimate at 2.5%, does not appear to be that daunting when compared to other economies. As a result, persistent pressure on the yen appears to be a far stronger catalyst for further policy tightening than inflation alone. Additionally, if US decides to move towards a tighter policy, the US-Japan interest rate differential could widen further, potentially triggering accelerated rate hikes in Japan to curb currency weakness.
