Funding Liquidity Risk : Definition and Measurement

In this paper we propose definitions of funding liquidity and funding liquidity risk and present a simple, yet intuitive, measure of funding liquidity risk based on data from open market operations.

We are also able to document downward spirals between funding liquidity risk and market liquidity
