ABSTRACT
We analyze the impact of oil price shocks on three unique fixed income asset classes representing conventional bonds, Islamic bonds (sukuks) and green bonds by employing network dynamic connectedness framework. Our sample period ranges from May 1, 2009, to March 1, 2022, covering the aftermath of global financial crisis, subsequent boom and bust of oil markets and the COVID-19 pandemic. We document a sizable connectedness of oil price shocks with fixed income asset classes. We document oil demand and risk shocks' role as main transmitters of spillover. Our findings have important implications for investors, policy makers and regulators.
ABSTRACT
This study investigates the asymmetric connectedness and spillover effects between two ethical fixed-income assets (Sukuk and green bonds) with regard to global risk factors using a sample of 15 Sukuk markets and green bond indices. This complex network allows us to examine the extreme risk spillover and interlinkages across green bonds and Sukuk under different market conditions, captures sudden upward changes in the total and net spillover indices and hence, serves as an alerting system for any impending crisis in relation to global risk factors. Empirical results indicate a persistency feature in the connectedness between Hong Kong and Malaysian, and UK and Nigerian Sukuk markets under different market conditions. More importantly, Sukuk and green bond markets are not largely affected by global risk factors in the middle, upper and lower quantiles. Findings from the portfolio analysis show that Sukuk is effective in hedging the risks of green bonds and global factors. These results of potential diversification characteristics and risk reduction benefits are robust and hold during the Covid-19 pandemic period. Finally, our findings are of paramount importance for investors who are interested in ethical investments as well as policymakers in order to maintain a stable and sound financial system.
