Bitcoin traders are closely monitoring the Bank of Japan's upcoming interest rate decision, with expectations of a potential hike to 1%. As of June 9, leveraged funds held over 115,000 speculative short positions in the yen, marking a nine-year high. A rate increase could lead to the liquidation of these positions, causing yen appreciation and affecting yen-funded carry trades. Historically, such moves have triggered significant market volatility. Following a similar rate hike in July 2024, the yen surged, impacting Wall Street, the Nikkei index, and the cryptocurrency market, with Bitcoin dropping from $65,000 to $50,000 in a week. If Governor Kazuo Ueda signals further tightening, cryptocurrencies could face heightened volatility due to their sensitivity to liquidity changes.
