In August 2007 the BKBM-LIBOR differential switched from positive to negative and then widened considerably following the collapse of Lehman brothers in September 2008, before narrowing gradually as the turmoil financial markets subsided. Our structural regression model and decomposition analyses show that changes in liquidity largely explain the changes in the BKBM-LIBOR differential and that credit risk factors only played a minor role. However our analysis also shows that liquidity in the offshore market also prices information regarding counterparty credit risk, suggesting that our initial results could understate the role played by credit risk factors.
