Financial Markets and Agricultural Commodities: Volatility Impulse Response Analysis

Indeed, with the introduction of agricultural commodity as an alternative asset class in investment portfolios, and the consequent increasing integration between commodity markets and major financial markets, there has been a growing convergence of risk-adjusted returns on assets class across markets, and an increase in the risk of volatility spillovers from outside to commodity markets due to portfolio rebalancing of institutional investors (Adams and Gluck, 2015).
