The Bank of Japan's decision on its monetary policy has heightened expectations of a potential increase in borrowing costs by the end of the second quarter. This development has positively impacted the yen, while bitcoin continues to face pressure.

The central bank maintained its benchmark interest rate at 0.75%, as expected, but the decision was not unanimous, with three members voting in favor of a rate hike. This 6-3 vote split is the largest since Kazuo Ueda took office as governor, indicating a growing inclination among policymakers to raise borrowing costs.

The 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% from 1%. The reasoning behind the Bank of Japan's hawkish stance is largely attributed to the disruptions in global energy prices caused by the war, which have led to increased inflationary pressures in energy-import-dependent economies like Japan. As a result, 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%.

Trends in the Japanese yen are closely monitored due to its 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. As a result, yen strength can trigger the unwinding of these carry trades, which may lead to global risk aversion. However, recent data on market flows suggests that yen-funded carry trades remain active, with Japan continuing to increase its holdings of U.S.
