Liquidity and credit risks in the UK’s financial crisis

This paper investigates the relationship between credit risk and liquidity components in the interbank spread and how this relationship unfolded during the recent financial crisis. We find that prior to the central bank’s Bank of England’s intervention counterpart risk was a major factor in the widening of the spread and also caused a rise in liquidity risk. However, this relationship was reversed after central bank started quantitative easing (QE). Using the accumulated value of asset purchases as a proxy for central bank’s liquidity provisions, we provide evidence that the QE operations were successful in reducing liquidity premia and ultimately, indirectly, credit risk.
