The Bank of Japan's recent monetary policy decision has heightened expectations of an interest rate increase by the end of the second quarter. As a result, the yen has appreciated in value, 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 raise borrowing costs. The central bank has also revised its forecast for core inflation to 2.8% for the current fiscal year and lowered its economic growth projections to 0.5%. The primary driver behind the Bank of Japan's shift towards a more hawkish stance is the disruption of global energy prices due to war-related issues, which has led to increased inflationary pressures in energy-import-dependent economies like Japan.

Traders are now pricing in a 74% chance of a rate hike on June 16, aligning with the consensus among Bank of Japan watchers. The Japanese yen has risen, causing the dollar-yen pair to decline by nearly 0.5%, while the bitcoin-yen pair has fallen by 0.6%. The yen's strength is closely monitored due to its historical role as a funding currency, and sustained yen strength is 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, leading to the unwinding of these carry trades when the yen strengthens.

However, recent data on market flows suggests that yen-funded carry trades remain active, with Japan continuing to increase its holdings of U.S. Treasury notes.
