The Bank of Japan held its benchmark interest rate at 0.75% on Tuesday, but the decision masked deeper divisions within the central bank. Three of nine board members dissented in favor of an immediate rate increase, marking the largest policy split since Governor Kazuo Ueda took office. Markets are now pricing a 74% probability of a rate hike by June 16, a shift that has already strengthened the yen and pressured bitcoin lower across major trading pairs.
BoJ’s Hawkish Pivot Reflects Energy Pressures
The Bank of Japan’s recent tilt toward tightening stems from war-related disruptions in energy flows through the Strait of Hormuz, pushing global energy prices higher. Japan, as an energy-import-dependent economy, faces upward pressure on inflation as a result. The central bank revised its core inflation forecast to 2.8% for the fiscal year while cutting its economic growth projection to 0.5%, down from 1%. This dual squeeze on growth and inflation has emboldened board hawks to signal readiness for policy normalization sooner rather than later.
Markets Price Aggressive Tightening Timeline
The 6-3 vote split represents the largest dissent under Ueda’s tenure, signaling a fundamental shift in the BoJ’s internal consensus. Markets have responded by pricing a 74% probability of a rate hike by June 16. The USD/JPY pair fell 0.5% to 158.95 following the announcement, while bitcoin dropped 0.6% to 12.28 million yen on bitFlyer. These moves reflect the mechanical impact of yen strength on carry-trade-funded positions. However, the narrative around an imminent carry trade unwind remains contested among market observers.
Treasury Purchases Complicate Carry Trade Thesis
Japanese institutions have increased U.S. Treasury holdings by $14 billion in recent months, bringing Japan’s total stockpile to $1.24 trillion, the highest level since February 2022. This represents the 13th consecutive monthly purchase over the last 14 months, suggesting Japanese investors continue chasing higher yields overseas despite rate hike expectations. LondonCryptoClub’s analysis disputes claims of an imminent carry trade unwind, arguing that February’s Treasury data proves carry trades remain active. The August 2024 carry trade unwind, which sent bitcoin from $65,000 to $50,000 in a single week, demonstrated the leverage embedded in these positions.
Next Decision Point in Mid-June
The BoJ’s next monetary policy decision arrives on June 16, when the board will reassess inflation, growth, and geopolitical risks. The dissent on Tuesday signals that a rate hike is no longer a tail risk but a base-case scenario for a meaningful portion of the policy committee. Traders and crypto investors holding leveraged yen positions face material downside if the central bank follows through on the hawkish signal.
