The Bank of Japan's policy decisions carry far more weight than most traders recognize. Consider the ripple effects: global bond yields shift, currency valuations swing, and liquidity flows get redirected across markets worldwide. When the BOJ's stance turns ambiguous or hawkish, risk assets feel the pressure first—and crypto is no exception. The uncertainty in Japan's monetary direction tends to spook investors into defensive positions, which means altcoins and Bitcoin often pull back alongside broader risk-off sentiment in equities.
