The Bank of Japan's recent monetary policy decision has heightened expectations of an impending interest rate increase by the end of the second quarter. The yen has responded positively, while bitcoin continues to struggle.

The central bank maintained its benchmark interest rate at 0.75%, as widely anticipated, but the decision was not unanimous, with three board members pushing for an immediate rate hike. This 6-3 vote split is the largest since Kazuo Ueda took office as governor, indicating a growing inclination among policymakers to increase 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 primary reason behind the Bank of Japan's hawkish stance is largely attributed to the disruption of energy flows through the Strait of Hormuz, which has driven up global energy prices and contributed to inflationary pressures in energy-import-dependent economies like Japan.

As a result, traders have priced in a 74% chance of a rate hike on June 16, aligning with the consensus among Bank of Japan watchers. The Japanese yen has surged, causing the dollar-yen pair to decline by nearly 0.5% to 158.95, a notable move for major currencies. 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 historical role as a funding currency.

Prolonged yen strength is often associated with risk aversion, as the Bank of Japan's extended period of ultra-low interest rates has encouraged traders to borrow in yen and invest in higher-yielding assets abroad. Consequently, yen strength can trigger the unwinding of these carry trades, which was widely cited as a factor in the decline of global risk assets in August 2024. However, the latest available data on market flows from February suggests that yen-funded carry trades remain active, with Japan increasing its holdings of U.S. Treasury notes.

According to the founders of LondonCryptoClub, 'Japan, the largest foreign holder, raised its stockpile by +$14 billion, to $1.24 trillion, the highest since February 2022. This marks Japan's 13th monthly purchase of the last 14 months, as Japanese institutions continue chasing higher yields overseas.' They also stated, 'As we have said, there is no “JPY carry unwind” trade.

Those who are talking about that don’t understand how Japanese investors operate and you should ignore them.'
