Bank of Japan Holds Rates at 1% While Signaling Inflation Risks Ahead

Policy Hold With a Hawkish Twist

The Bank of Japan maintained its short-term interest rate at 1% on July 31, a move widely anticipated by markets following June's hike to a three-decade high. But the decision came with sharper language on inflation risks than the central bank has used in recent quarters.

For the first time, the BOJ warned that underlying inflation could overshoot its 2% target as medium and long-term price expectations climb and companies grow bolder on pricing and wage decisions. The statement marked a notable shift from April's quarterly outlook, which simply noted inflation was approaching the target.

"We must pay due attention to keep such a risk from materializing and exert an adverse impact on the economy," the central bank said in its quarterly report.

Governor Kazuo Ueda reinforced the message at his press briefing. "Given that underlying inflation is approaching our 2% target, we must scrutinize upside price risks more than ever," he said. "We will debate our policy from our next meeting onward with this point in mind."

The decision was not unanimous. Board member Hajime Takata dissented for the second consecutive meeting, pushing for a 25-basis-point hike to 1.25% to address inflation risks from external demand shocks.

Currency Intervention Before the Meeting

The BOJ's announcement followed Tokyo's intervention in New York markets on July 30, when Japanese authorities sold dollars and bought yen in an attempt to arrest the currency's decline. The yen had weakened to near 160 per dollar, approaching levels last seen during spring's record intervention campaign.

US Treasury Secretary Scott Bessent signaled Washington's tacit approval, telling Fox Business Network that Japan may have stepped in to support a currency that appeared "very undervalued." Tokyo's top currency diplomat, Atsushi Mimura, declined to confirm the operation but hinted at coordination with the Federal Reserve, including so-called rate checks, and noted close communication with South Korea, which also intervened on July 30.

The move did little to provide lasting support. The yen hovered around 160.76 per dollar after the BOJ decision, despite the central bank's hawkish tone lifting the two-year Japanese government bond yield.

If confirmed, the intervention would mark Tokyo's first foray into currency markets since its record 73 billion dollar yen-buying spree between late April and early May, an effort that failed to reverse the currency's downtrend.

AI Demand and Currency Weakness Drive Price Pressures

In its quarterly outlook, the BOJ pointed to two new factors contributing to inflation: surging global demand for semiconductors and AI-related goods, and the yen's recent weakness. Both are likely to push up prices for durable goods, the central bank said.

The BOJ revised its core inflation forecast for the fiscal year ending March 2027 down to 2.5% from 2.8%, attributing the adjustment to stabilizing oil prices. But it raised its projection for fiscal 2027, and emphasized that price risks remain tilted to the upside even as economic outlook risks are balanced.

The central bank also noted that concerns over the economic impact of the Middle East conflict are receding, further underscoring its focus on managing inflation rather than downside growth risks.

"The perspective of stabilizing underlying inflation around 2% is becoming important" in guiding policy to avoid an overshoot that damages the economy, the BOJ said.

Rate Path Expectations

The BOJ raised rates to the 31-year high of 1% in June and has pledged to continue tightening if economic and price conditions warrant. Most analysts polled by Reuters expect another 25-basis-point increase by year-end, bringing the policy rate to 1.25%.

Marcel Thieliant, head of Asia-Pacific at Capital Economics in Singapore, called the outlook report hawkish. "We're sticking to our non-consensus view that the central bank will lift interest rates to 2% by the end of next year," he said, noting that Takata's dissent is remarkable given the June hike.

The slow pace of rate increases has drawn criticism for contributing to the yen's 40-year low, which has driven up import costs and squeezed households and retailers. Data released on July 31 showed annual core inflation in Tokyo accelerated to 1.7% in July, pointing to broadening price pressures.

The central bank now lists AI-driven demand, currency movements, and Middle East developments among the factors it will monitor in determining the timing and pace of further rate hikes, adding complexity to its policy calculus as it seeks to anchor inflation near target without choking off growth.
