The Bank of Japan's recent monetary policy decision has heightened expectations of a potential borrowing cost increase by the end of Q2, with the yen experiencing a surge while bitcoin faces downward pressure. Despite maintaining its benchmark interest rate at 0.75%, the decision was not unanimous, with three board members advocating for an immediate rate hike.

This 6-3 vote split marks the largest since Governor Kazuo Ueda's tenure, signaling a growing inclination among policymakers to raise borrowing costs. The central bank also revised its core inflation forecast to 2.8% for the fiscal year and lowered economic growth projections to 0.5%. Traders have priced in a 74% chance of a rate hike by June 16, aligning with the consensus among Bank of Japan observers. The Japanese yen has risen, causing the dollar-yen pair to drop nearly 0.5%, while the bitcoin-yen pair has fallen by 0.6%.

Trends in the yen are closely watched due to its role as a funding currency, with sustained strength often associated with risk aversion. This is because the Bank of Japan's prolonged period of ultra-low interest rates has encouraged traders to borrow in yen and invest in higher-yielding assets abroad, potentially triggering the unwinding of carry trades. However, recent data on market flows suggests that yen-funded carry trades remain active, with Japan increasing its holdings of U.S.
