In a pivotal monetary policy meeting on Tuesday, the Bank of Japan (BoJ) signaled a potential shift in its approach to interest rates, heightening expectations among market participants for a possible rate hike by the end of the second quarter. The yen experienced a notable appreciation amid these developments, while bitcoin faced continued downward pressure.
The BoJ maintained its benchmark interest rate at 0.75%, a decision anticipated by many analysts. However, the decision was not without contention; three members of the board advocated for an immediate rate increase, resulting in a 6–3 vote split. This division marks the most significant dissent since Kazuo Ueda assumed the governorship, reflecting a growing inclination among policymakers to adopt a more hawkish stance on interest rates.
In tandem with this decision, the central bank revised its inflation forecast upwards to 2.8% for the current fiscal year. Conversely, economic growth projections were lowered from 1% to 0.5%, indicating a more cautious outlook. The BoJ’s shift appears largely influenced by recent disruptions in energy flows through the Strait of Hormuz, which have driven up global energy prices and exerted inflationary pressures on energy-import-dependent economies like Japan.
Post-announcement, traders quickly adjusted their expectations, assigning a 74% probability to a rate hike on June 16. This aligns with broader sentiments among financial analysts who had predicted a June increase ahead of the BoJ’s latest meeting.
The resulting market reaction saw the Japanese yen strengthen, pushing the dollar-yen (USD/JPY) exchange rate down nearly 0.5% to 158.95. Historically, such rate increases or speculation of them tend to boost the currency in question, in this case, the yen. Conversely, the bitcoin-yen exchange rate (BTC/JPY) dropped by 0.6%, falling to 12.28 million yen, in line with bitcoin’s ongoing struggles in dollar-priced markets.
The dynamics surrounding the yen are particularly noteworthy, given its long-standing role as a funding currency. A robust yen often indicates risk aversion among investors. The BoJ’s extended period of ultra-low interest rates, especially during the post-COVID era, had encouraged investors to borrow in yen to channel funds into higher-yielding assets overseas. When the yen strengthens, it can trigger the unwinding of these carry trades, which was particularly evident in late August 2024, when bitcoin plummeted from $65,000 to $50,000 in just a week.
Despite rising expectations for a June rate hike, recent data suggests that the unwinding of yen-funded carry trades may not be imminent. The latest market flow information indicates that Japan has been increasing its holdings of U.S. Treasury notes, further supporting the notion that these carry trades remain active. Japan, currently the largest foreign holder of U.S. debt, bolstered its stake by $14 billion, reaching $1.24 trillion—the highest level since February 2022. This marks Japan’s 13th month of purchases in the last 14 months as domestic institutions seek higher yields abroad.
Commentators from the newsletter service LondonCryptoClub caution against the narrative of a substantial “JPY carry unwind” trade, arguing that it misrepresents the behaviors and strategies of Japanese investors. They assert that those suggesting a significant unwind do not fully grasp the operational modalities of these investors and advise disregarding such claims.
