BOJ Raises Policy Rate to 1% as Yen Stays Weak and Inflation Persists

The Bank of Japan lifted its key short-term policy rate by 25 basis points to 1% on June 16, 2026, taking borrowing costs to their highest level since September 1995. The move would typically support the currency, yet the yen continued to slide against the US dollar. Inside the decision, the BOJ’s policy board backed the increase by a 7-1 vote, with one member dissenting on concerns over downside risks to the economy. Governor Kazuo Ueda did not attend the meeting for medical reasons. The hike, from 0.75% to 1%, marks the BOJ’s first increase since December 2025. Policymakers pointed to stubborn inflation, led by elevated energy costs. Tensions in the Middle East have kept oil prices high, adding pressure to consumer prices. The yen's weakness highlights the pull of interest rate differentials. Even at 1%, Japan's policy rate remains well below those in the US and other major economies. The yield gap continues to favor carry trades, where investors borrow in yen at low rates and invest in higher-yielding assets abroad. Bitcoin rose immediately after the BOJ's announcement. That reaction contrasts with earlier episodes of BOJ tightening, which have often weighed on risk assets, including crypto. The rate increases in 2024 and December 2025 coincided with digital-asset selloffs as the unwinding of yen-funded carry trades rippled through global markets. Investors are now focused on whether the BOJ delivers more hikes later in 2026. If the central bank continues with 25-basis-point steps, reaching 1.25% or 1.5% by year-end, the economics of yen-funded positions could change materially. A brief carry-trade unwind in mid-2024 triggered sharp volatility across global markets, including crypto. Ueda's absence also adds a layer of uncertainty. His return and any public remarks could reshape expectations for the BOJ's next moves.
