Why Bitcoin Structurally Decoupled from the S&P 500 in H2 2025
Market phase: Bitcoin is in a weak-to-neutral consolidation phase after a broader decline. Bearish bias remains conditional, but systemic stress is limited. In H2 2025, Bitcoin’s correlation with the S&P 500 fell sharply. This was not a temporary divergence, but a result of structural changes in market behavior. First, capital flows changed in nature. Spot Bitcoin ETFs shifted demand from short-term risk-on trading to allocation-driven inflows. These flows are largely independent of equity momentum, weakening the traditional correlation channel. Second, leverage risk was reduced. Derivatives markets moved toward stablecoin-based margin, while BTC-margined high leverage declined. This limited liquidation cascades, preventing equity volatility from spilling into Bitcoin. Third, macro liquidity bypassed crypto. Capital rotated into commodities and precious metals, leaving Bitcoin relatively sidelined. As a result, Bitcoin became less reactive to equity-driven risk sentiment. Fourth, market participants changed. Short-term, trend-following traders—those most likely to trade Bitcoin as an equity proxy—continued to exit. The remaining base consisted mainly of long-term holders and ETF-related custody. Fifth, price discovery became internal. Equity prices reflect earnings and rate expectations, while Bitcoin increasingly responds to supply constraints and holding behavior. The Stablecoin Supply Ratio (SSR) supports this view. Despite weak prices, SSR declined, indicating rising stablecoin purchasing power. Capital remained inside the crypto system rather than exiting to equities. Base scenario: continued consolidation driven by muted demand, not forced selling. Invalidation: renewed leverage buildup or broad stablecoin deployment. Conclusion: Bitcoin’s decoupling was structural—the mechanisms that once linked it to equities were largely removed. （Analysis Report No.160） The XWIN Group operates the DeFi platform “xwin.finance”.
