Bitcoin rebounded to $91,000 on April 10, 2025, following suspected intervention by Japanese authorities in the foreign exchange market. The yen's sharp appreciation against the U.S. dollar coincided with Bitcoin's recovery, suggesting a direct link between the two events. Analysts noted that the yen's sudden strength likely triggered a reversal of yen carry trades, where investors borrow yen at low interest rates to invest in higher-yielding assets like cryptocurrencies. The intervention's impact extended beyond Bitcoin, affecting altcoins and derivatives markets, and highlighting the interconnectedness of traditional finance and digital assets. The event underscores the influence of macroeconomic factors on cryptocurrency prices, as global monetary actions can swiftly alter market dynamics.
