What drives interbank rates? Evidence from the Libor panel

BIS Quarterly Review  |  March 2008  |

The risk premium contained in the interest rates on three-month interbank deposits at large, internationally active banks increased sharply in August 2007 and risk premia have remained at an elevated level since. This feature aims to identify the drivers of this increase, in particular the role of credit and liquidity factors. While there is evidence of a role played by credit risk, at least at lower frequencies, the absence of a close relationship between the risk of default and risk premia in the money market, as well as the reaction of the interbank markets to central bank liquidity provisions, point to the importance of liquidity factors for banks' day-to-day quoting behaviour.
