The Impact of Bitcoin ETF Approval on Bitcoin's Hedging Properties Against Traditional Assets

2025-12-14

AI Summary

This study investigates the structural impact of the U.S. Bitcoin spot ETF approval (January 2024) on Bitcoin’s hedging properties relative to traditional assets—U.S. equities (S&P 500), gold, and the U.S. Dollar Index. Employing rolling correlation analysis, Chow tests, and the DCC-GARCH model to capture time-varying conditional correlations, we systematically identify and date-stamp a regime shift in cross-asset dependencies induced by the ETF event. Results reveal a statistically significant increase in Bitcoin–equity correlation, near-zero correlation with gold, and persistent negative correlation with the dollar. These findings indicate a functional transition of Bitcoin from “digital gold” toward a risk asset: its exposure to equity market risk has intensified, its safe-haven role vis-à-vis gold has markedly diminished, while its hedge efficacy against dollar appreciation remains intact. This work provides novel, empirically grounded evidence on Bitcoin’s evolving role in modern portfolio construction and asset allocation.

Abstract

The approval of the Bitcoin Spot ETF in January 2024 marked a transformative event in cryptocurrency markets, signaling increased institutional adoption and integration into traditional finance. This study examines Bitcoin's changing relationships with traditional assets, including equities, gold, and fiat currencies, following this milestone. Using rolling correlation analysis, Chow tests, and DCC-GARCH models, we found that Bitcoin's correlation with the S&P 500 increased significantly post-ETF approval, indicating stronger alignment with equities. Its relationship with gold stabilized near zero, while its correlation with the U.S. Dollar Index remained consistently negative, reflecting its continued independence from fiat currencies. These findings offer insights into Bitcoin's evolving role in portfolios, implications for market stability, and future research opportunities on cryptocurrency integration into traditional financial systems.
