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 existing demand for the bond, but improves the bond allocation by allowing long-term investors to become levered basis traders and absorb more of the bond supply. Our framework characterizes conditions under which CDS introduction raises bond prices. The model also 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.
