The Bank of Japan (BoJ) has just reached a historic milestone by raising its benchmark interest rate to 1.25%, marking its highest level since 1995. This decision, approved by a seven-to-two majority, is part of an unprecedented monetary tightening cycle—the second in just three months. The Japanese central bank is primarily seeking to counter persistent inflation threatening its 2% target, exacerbated by the rising cost of energy imports. This strategic move also comes amid diplomatic pressure from Washington, which is calling for a stabilization of the yen to support the stability of global financial markets.
Against all odds, this rate hike did not penalize digital assets. On the contrary, Bitcoin (BTC) showed bullish momentum, reaching the $77,500 mark shortly after the official announcement. Conversely, the yen's reaction was paradoxical: despite the increase in borrowing costs, the Japanese currency weakened against the dollar. This phenomenon suggests that markets had largely priced in the decision and that the strength of the greenback, backed by the US Federal Reserve's recent policy stance, continues to dictate the overall trend in the foreign exchange market.
The primary point of concern for investors remains the carry trade mechanism—a strategy that involves borrowing in yen to invest in higher-yielding assets abroad. Fears of a massive unwinding of positions, similar to the stock market shock seen last August, still loom over equity and crypto markets. However, the substantial yield spread between Japanese and US rates—which currently sit between 3.75% and 4%—maintains a degree of profitability for yen borrowers, limiting the risk of widespread panic for now.
In the short term, the correlation between the monetary policies of Tokyo and Washington will be decisive. If financial analysts expect further adjustments from the Fed as early as October, pressure could build on Bank of Japan Governor Kazuo Ueda to continue this monetary normalization cycle. For Bitcoin holders, the critical scenario remains a sharp and sudden appreciation of the Japanese currency. As long as the USD/JPY pair holds above the 156 threshold, the carry trade appears to enjoy a reprieve, thereby preserving a degree of stability for risk assets.
