The Bank of Japan's recent monetary policy decision has heightened expectations of a potential interest rate increase by the end of the second quarter. The yen has responded positively, while bitcoin continues to face challenges. The central bank maintained its benchmark interest rate at 0.75%, although the decision was not unanimous, with three board members advocating for an immediate rate hike. This 6-3 vote split is the largest since Kazuo Ueda assumed the role of governor, indicating a growing inclination 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 adjusted its economic growth projections downward to 0.5% from 1%. The primary factor driving the Bank of Japan's hawkish stance is the disruption in global energy prices due to war-related issues, which has contributed to inflationary pressures in energy-import-dependent economies like Japan.

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 appreciated, causing the dollar-yen pair to decline by nearly 0.5% to 158.95.

The bitcoin-yen pair listed on bitFlyer has also fallen by 0.6% to 12.28 million yen, consistent with the weakness in dollar-denominated prices. Trends in the Japanese yen are closely monitored due to its role as a funding currency. Prolonged yen strength is often associated with risk aversion, as it can trigger the unwinding of 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. Treasury notes.
