Source text: Bitcoin is experiencing a divergence in performance, showing strength against the U.S. dollar while lagging against the Japanese yen. This comes as Japan's producer price index for June surged to 7.1%, the fastest annual increase since March 2023, fueling expectations of further Bank of Japan rate hikes. A former central bank official suggested that rates could rise above 2%, contributing to the yen's strength. The Japanese yen and Bitcoin have developed a strong positive correlation, often moving together against the U.S. dollar. If this correlation persists, yen upswings could benefit Bitcoin overall, despite BTC/JPY pairs underperforming. Meanwhile, Japan's Government Pension Investment Fund, managing ¥277 trillion ($1.87 trillion) in assets, faces pressure to invest more in local assets, potentially causing volatility in global markets.
