Safe-Haven dynamics and financialization: a multiscale wavelet and asymmetric risk analysis of Bitcoin and gold

This article examines how the market roles of Bitcoin and gold evolved over the 2020–2026 period of institutional maturity. Departing from static linear correlations, we combine a time–frequency framework – bivariate, partial, and multiple wavelet coherence – with multifractal detrended fluctuation analysis and asymmetric-risk metrics (the Omega and a Sharpe ratio). Partial and multiple estimators isolate the intrinsic equity linkage of each asset from the surrounding monetary environment, mapping the distinct channels through which systemic shocks are transmitted. The evidence is consistent with a pro-cyclical, high-beta profile for Bitcoin: its co-movement with equities persists once real interest rates and central bank liquidity are partialled out, and its anti-phase relationship with market fear implies participation in sell-offs. The decisive distinction from gold is directional rather than one of magnitude. Microstructurally the two assets are comparably efficient in normal conditions and comparably fragile in the tails; they differ in the composition of their macro-financial dependence – gold organized around the currency and rate complex, Bitcoin around equities and volatility. Their risk-adjusted profiles are mirror-images across horizons: gold a dependable short-horizon stabilizer, Bitcoin a diversifier whose return asymmetry translates into long-term growth only over extended holding periods.
