Using a unique and comprehensive dataset of European repurchase (repo) rates, we explain the sources and time variation a ecting the risk premium. Our results show that the EH cannot be rejected when loans are secured by safe collateral and that unconventional monetary policy can substantially reduce risk premiums. By contrast, the EH is violated when interest rates are a ected by funding risk and collateral risk.Expectations hypothesisinterest ratesrisk premiummonetary policyrepopresentation
