What is the correlation between crypto and the Nasdaq?

The correlation between Bitcoin (and broader crypto markets) and the Nasdaq Composite has been one of the most debated topics in macro investing since 2020. During Bitcoin's early years (2009-2019), correlation with equity indexes was near zero, supporting the narrative of crypto as an uncorrelated "digital gold" that could diversify traditional portfolios. Starting in 2020, the correlation rose substantially, with rolling 90-day correlations frequently exceeding 0.6 and occasionally approaching 0.8 during risk-off episodes.

The rising correlation has a logical explanation. As institutional investors, hedge funds, and algorithmic traders entered crypto markets, they brought the same risk management frameworks and positioning behaviors they use in equity markets. When macro sentiment deteriorates (rising rates, recession fears, geopolitical shocks), these participants reduce exposure to "risk assets" broadly, selling both Nasdaq stocks and crypto simultaneously. When sentiment improves (Fed pivots, strong economic data), they add risk across the board. Bitcoin, as a high-beta risk asset with no cash flows, tends to amplify these moves.

The correlation is not constant and does have periods of divergence. Bitcoin has occasionally decoupled from equities during crypto-specific events: exchange failures (FTX collapse), regulatory crackdowns, halving-driven narratives, and ETF approval catalysts. Similarly, the correlation weakens during periods of steady, low-volatility equity markets where crypto-specific drivers dominate day-to-day price action. But during macro-driven episodes, the positive correlation reasserts itself, undermining the diversification thesis.

For portfolio construction, the rising Nasdaq correlation means that adding Bitcoin to a stock-heavy portfolio provides less diversification than the early narrative suggested. During the 2022 bear market, both the Nasdaq (down 33%) and Bitcoin (down 65%) suffered simultaneously, offering no hedge when it was needed most. Investors seeking uncorrelated returns from crypto must recognize that the correlation is regime-dependent: it is lowest during calm, crypto-specific bull markets and highest during macro stress, which is precisely when diversification is most valuable. This asymmetric correlation profile is a critical consideration for anyone allocating to crypto as part of a broader investment strategy.
