The Bank of Japan's recent monetary policy decision has heightened expectations of a potential interest rate hike by the end of the second quarter, with the yen experiencing a boost and bitcoin facing downward pressure. Although the central bank maintained its benchmark interest rate at 0.75%, the decision was not unanimous, with three board members advocating for an immediate rate increase. This 6-3 vote split marks the largest division since Kazuo Ueda took office as governor, indicating a growing push among policymakers to raise borrowing costs. The central bank also revised its forecast for core inflation to 2.8% for the current fiscal year and lowered its economic growth projections to 0.5%.

Markets have quickly responded, pricing in a 74% chance of a rate hike in June, aligning with the consensus among Bank of Japan observers. The Japanese yen saw a significant increase, pushing the dollar-yen pair down nearly 0.5%, while the bitcoin-yen pair fell by 0.6%. Trends in the yen are closely monitored due to its role as a funding currency, and sustained yen strength is often associated with risk aversion, potentially triggering the unwinding of carry trades.

However, recent data suggests that yen-funded carry trades remain active, with Japan increasing its holdings of U.S. Treasury notes, indicating a continued pursuit of higher yields overseas.
