Unproductive debt
Credit and related interest income have historically been viewed as service and related payment for lending productively. However, in a highly collateralized and risk-averse financial system credit may be granted mainly on the basis of collateral value and aim at wealth extraction rather than wealth creation. On the macroeconomic level, this creates unproductive debt, i.e. debt that is not backed by productive investment. This type of debt carries greater systemic default risk. The rapid increase of debt and leverage after the great financial crisis may be an indication of an unproductive debt problem. For the purpose of macro trading, relevant systemic risk indicators should feature intelligent debt-to-GDP ratios and trackers of collateral values.
