Professor Sang Hoon Kang and his team analyzed seven green cryptocurrencies alongside three major green financial benchmarks using data from November 2017 to July 2024. Their findings, published in the journal Financial Innovation, identify a U-shaped pattern of connectivity: while assets may offer diversification during stable periods, they become dangerously synchronized during market booms or downturns. This synchronization facilitates financial contagion, undermining the protective role traditionally attributed to green bonds and ESG investments.

Green Cryptocurrencies Often Amplify Market Volatility, Study Finds
Investors seeking refuge in green digital assets may be miscalculating their risks, as new research suggests these tokens often act as volatility transmitters rather than defensive hedges. A study from Pusan National University reveals that assets like Cardano and Stellar frequently destabilize sustainable portfolios during market turbulence.
The research utilized a quantile vector autoregression framework to map risk spillovers across different economic conditions. The data shows that traditional green assets—including clean energy indices and ESG funds—typically function as net receivers of volatility, absorbing shocks generated by digital counterparts. Cardano and Stellar were specifically identified as primary sources of this systemic instability. These insights suggest that the integration of green cryptocurrencies into investment portfolios requires more dynamic management, as the assumption that all sustainable assets provide a safe haven is increasingly unsupported by market behavior.
