A new study from Pusan National University challenges the long-held belief that green cryptocurrencies offer a safe hedge in turbulent markets. The research, led by Professor Sang Hoon Kang, analyzed daily market data from November 2017 to July 2024 to understand risk transmission across sustainable financial markets.
Cardano has been navigating major protocol upgrades, including the Cardano Van Rossum Hard Fork: Lower Fees, On-Chain Governance Control, which could further influence its market dynamics.

Key Findings: Cardano and Stellar as Volatility Transmitters
Using a quantile vector autoregression framework, the researchers examined how risk flows between seven green cryptocurrencies (including Cardano, Stellar, and others) and three major green financial benchmarks—green bonds, clean energy stocks, and ESG portfolios. The findings reveal a stark divergence: while green bonds and ESG assets tend to absorb market shocks, certain green cryptocurrencies like Cardano and Stellar act as consistent transmitters of volatility, especially during bearish and normal market conditions.
The study’s publication in the journal Financial Innovation on June 9, 2026, notes that this asymmetry challenges the assumption that all sustainable assets provide stable diversification. According to Prof. Kang, “As green cryptocurrencies are getting more integrated into sustainable investment portfolios, we wanted to understand their hedging capability and how it differs from traditional green finance options.” The data demonstrates that during times of economic distress, these digital assets can amplify risk rather than dampen it.
Implications for Sustainable Portfolios and What to Watch
For portfolio managers blending ESG and crypto, the study serves as a critical warning. Dynamic hedging models that treat all green assets as homogeneous may be faulty. Investors may need to differentiate between green bonds—which offer clear absorption properties—and proof-of-stake cryptocurrencies, which appear more sensitive to overall market turbulence. The results also raise questions about whether the “green” label alone is sufficient for risk classification.
Future research, as suggested by the team, could explore the role of stablecoins, tokenized green bonds, and evolving regulatory frameworks. Meanwhile, the divergent behavior of assets like Cardano and Stellar underscores the importance of granular, quantile-based analysis when building resilient crypto-ESG strategies. Monitoring protocol upgrades and market events for these cryptocurrencies will be essential for anyone seeking genuine hedging characteristics.
