Dynamic risk and hedging strategies in post-COVID digital asset sectors

Abstract

Time-varying parameter vector autoregressive models analyze post-pandemic risk spillover dynamics within equally-weighted digital asset sectors, focusing on the year following the COVID-19 pandemic declaration. This analysis highlights an initial surge in pandemic-induced spillovers, followed by a gradual decline, underscoring market resilience. Stablecoins are identified as primary net receivers of volatility, while Smart-contract, Binance-chain, and DeFi sectors emerge as main net transmitters. Frequency-based analysis reveals these sectors predominantly drive short-term spillover dynamics. Long/short portfolio assessments pinpoint Smart-contract tokens as the most effective post-pandemic hedgers, with NFT, Metaverse, and DeFi showing substantial increases in hedging effectiveness. This identification of efficient hedgers proves consistent across various specifications, including value-weighted indices, individual assets, alternative post-outbreak periods, extended post-pandemic periods, and different lag lengths.
