Why Are Credit Card Rates So High?

Credit card interest rates are notably high, averaging 23% annually in 2023, due to several factors. Banks face significant default risks and typically set interest rates based on predicted lifetime defaults when accounts are originated. While reward expenses are substantial, they are covered by interchange income, challenging the idea that high rates solely recoup these costs. Additionally, operational costs and market power contribute significantly to pricing. Lastly, credit card loans carry a non-diversifiable risk, meaning banks require compensation for this exposure, particularly during economic downturns.
