Quantile connectedness among digital assets, traditional assets, and renewable energy prices during extreme economic crisis

This study delves into an exploration of quantile connectedness across the domains of digital and traditional financial assets with the renewable energy prices index. The daily frequency dataset, spanning from January 02, 2018, to December 04, 2023, encapsulates diverse economic crises. Our inquiry elucidates distinctive patterns by employing empirical analyses utilizing quantile connectedness and Time-Varying Parameter Vector Autoregressive (TVP-VAR) methodologies. In this context, DeFi assets (Chain-link) emerge as the primary recipient of information shocks, while Bitcoin distinguishes itself as the preeminent transmitter of such shocks within the network. Notably, digital assets manifest heightened volatility in contrast to traditional and energy indices. Furthermore, our findings underscore that the gaming industry, specifically focusing on Non-Fungible Tokens (NFT), presents itself as the most fitting asset for portfolio inclusion. This assertion gains credence from its comparatively lower degree of connectedness with other underlying assets. These findings have significant implications for investors and portfolio managers, furnishing valuable insights into the dynamics of asset interdependencies. Consequently, this aids in cultivating a more discerning approach to investment decision-making. • Bitcoin is a significant transmitter of shocks, whereas DeFi assets like Chain-link predominantly receive them, highlighting their central roles in financial networks. • Digital assets exhibit higher volatility than traditional and energy assets. The gaming industry, notably through Non-Fungible Tokens (NFTs), offers potential for portfolio diversification due to their minimal connectedness with other asset classes. • The study provides critical insights into the interconnectedness of various assets, crucial for investors and portfolio managers to refine investment strategies and enhance decision-making.
