This paper aims at investigating the frequency connectedness and cross-quantile dependence between green bond and green equity markets. By decomposing green bond and green equity time series data into different frequency bands, we first identify how connectedness between green bond and green equity varies between the short-term, medium-term and long-term investment horizons. Next, we investigate the cross-quantile dependence between green bond and green equity to capture the connectedness between these markets across a wide range of market conditions. Our empirical results suggest that after controlling for movements in the general stock, energy and fixed-income markets, the dependence between green bond and green equity during normal market conditions is relatively small. On the other hand, green bond and green equity are more connected during extreme market movements, where spillovers from green equity to green bond tend to be larger than spillovers in the opposite direction. We also find that across all market conditions, the spillover effects between green bond and green equity are short-lived, as the degree of connectedness dissipates in the medium- and long-term investment horizons. Our results have important implications for environmentally conscious investors and policymakers.
