Interdealer Price Dispersion

Abstract

Intermediation capacity varies across dealers and, as a result, misallocation of credit risk reduces the risk-bearing capacity of the dealer sector and increases effective market-level risk aversion. When the efficient reallocation of credit risk within the dealer sector is impaired, interdealer price dispersion increases. Empirically, interdealer price dispersion is a strong determinant of yield spread changes. When interdealer price dispersion is high, bond prices are low. Interdealer price dispersion explains a substantial portion of bond yield spread changes, the cross-section of bond returns, and the basis between yield spread changes and changes in fair-value spreads. We conclude that frictions within the dealer sector reduce the risk-bearing capacity of intermediaries and are thus crucial for intermediary bond pricing.
