Treating Uncertainty as Risk: The Credit Default Swap and the Paradox of Derivatives

The credit default swap (CDS) is implicated in the global financial crises because a vast market for securities collateralized by subprime mortgages and consumer debt could not have materialized if hedge funds and other holders of these instruments lacked a means of hedging default "risk." The argument is made that the CDS is an inherently defective concept because it is based on the assumption that future states of the economy are subject to probabilistic risk as opposed to uncertainty in the Keynes-Knight-Shackle-Davidson sense. The CDS also manifests the paradox of derivatives. By enabling individual money managers to safely increase leverage, it causes a system-wide buildup of leverage and financial fragility.
