Bank of Japan raises rates to highest since 1995 after former executive warned of falling behind on inflation

A week after former Bank of Japan executive director Hideo Hayakawa publicly urged the central bank to pick up the pace on rate hikes, the BOJ did exactly that. On June 16, the central bank raised its short-term policy rate by 25 basis points to 1%, marking the highest level since 1995.

The move was the first rate adjustment since December 2025, and it came with hawkish language suggesting more tightening could follow.

Hayakawa’s warning and the BOJ’s response

Hayakawa made his case on June 9, arguing that the BOJ risked falling behind the curve on inflation if it didn’t accelerate its normalization timeline. He suggested a June rate hike was likely, with a potential follow-up increase by October.

Seven days later, the central bank delivered. The 25 basis point increase brought the benchmark rate to 1%, up from 0.75% where it had sat since December 2025.

Back in April 2026, Hayakawa urged earlier rate hikes and projected multiple increases heading toward a terminal rate of around 1.5%. The BOJ’s actual policy trajectory has been tracking uncomfortably close to his recommendations.

The central bank’s hawkish signaling pointed to energy costs as a key concern, with geopolitical tensions in the Middle East driving persistent inflationary pressures.

This latest move extends a normalization journey that began in March 2024, when the BOJ first raised rates to a range of 0% to 0.1% after years of ultra-loose monetary policy.

Why Bitcoin barely flinched

Bitcoin showed modest gains following the June 16 announcement, displaying a resilience that caught some market observers off guard, a notable departure from the chaos that accompanied the yen-carry-trade unwind in August 2024.

The muted reaction likely reflects two things. First, markets had already priced in the hike after Hayakawa’s very public comments and broad consensus among analysts. Second, the crypto market’s relationship with central bank policy has matured, with traders having had multiple cycles to calibrate their expectations around BOJ moves.

What this means for investors

With Hayakawa projecting a terminal rate around 1.5%, there’s potentially another 50 basis points of tightening on the table. Whether that arrives by October, as he suggested, or stretches into 2027 will depend largely on inflation readings and energy market dynamics.

The yen-carry trade remains a significant force in global financial markets. For years, investors borrowed cheaply in yen to fund positions in higher-yielding assets, including crypto. Every BOJ rate hike makes that trade slightly less attractive, which theoretically reduces one source of liquidity flowing into risk assets.

The key divergence to watch is between the BOJ and other major central banks. If the Federal Reserve is cutting or holding while the BOJ is hiking, the interest rate differential narrows. That’s the mechanic that triggered the violent unwind previously, and it could resurface if the BOJ moves more aggressively than markets currently expect.
