We provide a model of non-redundant credit default swaps (CDSs), building on the observation that CDSs have lower trading costs than bonds. CDS introduction involves a trade-off It crowds out demand for the bond, but improves the bond allocation because it allows long-term investors to become levered basis traders. CDS introduction raises bond prices only when there is a significant trading-cost difference between bond and CDS. Our framework predicts a negative CDS-bond basis, turnover and price impact patterns that are consistent with empirical evidence, and shows that a ban on naked CDSs can raise borrowing costs.
