Cryptocurrency and Digital Asset Markets: Volatility Dynamics, Regulatory Shocks, and Institutional Adoption: An Empirical Analysis

Abstract

This study offers a much-needed empirical examination of cryptocurrency and digital asset markets across three related dimensions: return volatility and cross-asset contagion; the market impact of regulatory announcements; and the structural impact of institutional investor participation. We use a suite of econometric tools – such as DCC-GARCH modeling, event-study analysis, and quantile regression – on a novel dataset of minute-by-minute price and order-flow data for 38 major digital assets from January 2024 to March 2026 to report on a few important findings. First, the volatility of returns to cryptocurrencies decreased markedly from 2021 to 2022, but, on average, they remain 4.1 times as volatile as traditional financial assets, and tail-risk events are clustered around regulatory disclosure events. Second, abnormal returns from regulatory announcements are statistically significant, with a mean of −8.3% in the 48-hour window after the announcement (t = −6.14, p < 0.001), and are observed across 73% of the sampled digital assets across all jurisdictions, regardless of jurisdiction type. Third, as institutional participation increased (as reflected in exchange-traded product (ETP) inflows and the distribution sizes of on-chain wallets), the short-run volatility of asset prices declined by around 22%. In contrast, the cross-asset correlation increased simultaneously, raising new systemic risk considerations. Our work has implications for portfolio risk management, prudential regulation of intermediaries in the crypto sector, and the design of macro-prudential frameworks that are sufficient for a partially institutionalized crypto sector
