The Whys of the LOIS: Credit Risk and Refinancing Rate Volatility

présenté par

Raphael Douady (Riskdata; CES Univ. Paris 1)


The 2007 subprime crisis has induced a persistent disconnection between the LIBOR derivative markets of different tenors and the OIS swap market. Commonly proposed explanations for the corresponding spreads are a combination of credit risk and liquidity risk. However in these explanations the meaning of the terms credit and liquidity is typically not precisely stated, the liquidity in particular being often simply defined as a residual spread after removal of a credit component. In this paper we propose a stylized equilibrium model in which a LIBOR-OIS spread (LOIS) emerges as a consequence of a credit component determined by the slope of the CDS curve of a representative borrower, and a liquidity component corresponding to the volatility of the cost-of-capital of a representative lender. The related notion of liquidity appears as the optionality, valued by the aforementioned volatility, of dynamically adjusting through time the amount of a rolling OIS loan, as opposed to being stuck with lending a fixed amount up to the tenor horizon on LIBOR.
