With Bitcoin's correlation with the Nasdaq index rebounding to 0.78, traditional financial market movements now amplify crypto volatility. In the current macroeconomic context, this strong correlation allows investors to gauge crypto trends by monitoring Nasdaq dynamics, particularly shifts in risk appetite driven by interest rates, inflation data, and Fed policies. For example, rising U.S. Treasury yields may pressure both tech stocks and Bitcoin, while dovish monetary signals could lift both. However, crypto-specific factors (regulatory news, ETF approvals, network upgrades) must also be layered in, as sudden blockchain developments can decouple Bitcoin from equities despite high correlation. Traders should use Nasdaq trends as a macro filter while staying alert to crypto’s unique catalysts.
