This article exposes these difficulties using a simple analogy to life insurance premiums. An analogy is used because the logic is more easily understood in this context. The difficulties are unraveling the impact of risk premium, counterparty risk, market frictions, and strategic trading. Given a well-understood alternative to implied CDS default probabilities is available, actuarial-based default probabilities, banking regulations and risk management decisions should not be based on CDS implied default probabilities.TOPICS: Credit default swaps, credit risk management, big data/machine learning, counterparty risk
