Commodity-linked bonds as an innovative financing instrument for African countries to build back better

Commodity-linked bond, a type of state contingent claims, presents an innovative tool for African countries to mobilize resources on the international capital markets. Given their colossal financing needs, which has been worsened by the COVID-19 pandemic, African countries need to put in place innovative financing mechanisms to support their development frameworks for building back better. The issuing of this type of bond could provide an opportunity for commodity-producing African countries to hedge against fluctuations in their export earnings. The results show that the value of a commodity-linked bond increases as the price of the commodity indexed to the bond rises, suggesting that African countries should issue debt contracts that are tied to their export commodities so that their debt declines with plummeting export prices (or export revenues). A simple portfolio rule derived suggests that countries should issue more commodity-linked bonds than conventional debt if the variance of the portfolio is greater than twice the spread between the expected total return of the conventional debt and the commodity-linked bond. This rule supports the view that African countries' debt-service payments, for debt issued in the form of commodity-linked bonds, would decline whenever the price of their export commodities decline thus lightening their debt load.
