Abstract
This study investigates the evolving interdependence between cryptocurrencies and U.S. equities within a macro-financial context. The study contributes methodologically by introducing the Rolling-Window Kernel Regularized Partial Correlation (RW-KRPC), which is specifically designed to capture nonlinear, time-varying, and conditional linkages. The study uses daily data from 3/11/2016 to 8/18/2025, to examine this association. Correlations between the S&P 500 and Bitcoin/Ethereum turned negative during the COVID-19 crisis and the FTX collapse - suggesting temporary safe-haven behavior - and strengthened during the early-2024 spot Bitcoin ETF approval period, indicating heightened co-movement. Ethereum exhibits stronger equity co-movements after 2024. The study formulates policy recommendations based on these findings.
