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. This development has led to a surge in the yen, while bitcoin continues to face downward pressure. The central bank maintained its benchmark interest rate at 0.75%, but the decision was not unanimous, with three board members voting in favor of an immediate rate hike. This 6-3 vote split marks the largest division since Kazuo Ueda took office as governor, indicating a growing inclination among policymakers to increase borrowing costs.

The Bank of Japan also revised its forecast for core inflation upwards to 2.8% for the current fiscal year, while lowering its economic growth projections to 0.5% from 1%. The primary driver behind the Bank of Japan's shift towards a more hawkish stance is largely attributed to the disruptions in global energy prices caused by the conflict-related blockages in the Strait of Hormuz, which have exacerbated inflationary pressures in energy-import-dependent economies like Japan. In response to the decision, traders have priced in a 74% chance of a rate hike on June 16, aligning with the consensus among Bank of Japan observers. The Japanese yen has experienced a notable increase, pushing the dollar-yen pair down by nearly 0.5% to 158.95.

The bitcoin-yen pair has also fallen by 0.6% to 12.28 million yen, consistent with the decline in dollar-denominated prices. Trends in the Japanese yen are closely monitored due to its historical role as a funding currency, with sustained yen 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.

As a result, yen strength is often seen as triggering the unwinding of these carry trades. However, the latest available data on market flows from February suggests that yen-funded carry trades remain active, with Japan continuing to increase its holdings of U.S.
