The 52-week rolling correlation between Bitcoin and the USD/JPY currency pair has dropped to -0.90, marking its most negative level since late 2022, according to TradingView data. This significant negative correlation indicates that Bitcoin and the yen are moving in tandem against the dollar, challenging the traditional yen carry trade logic. Typically, a weakening yen would coincide with a Bitcoin rally, but the current data suggests otherwise. The correlation challenges the assumption that yen depreciation should lead to Bitcoin gains. Instead, if the Bank of Japan intervenes to strengthen the yen, it could potentially support Bitcoin prices. Analysts caution that correlation does not imply causation, and broader dollar strength may be influencing both Bitcoin and the yen. With the market anticipating a 25-basis-point rate hike by the Federal Reserve, the dollar has strengthened, impacting various assets including the euro and gold.
