Funding liquidity risk is negatively related to market liquidity ( Drehmann and Nikolaou, 2013) . Banks need to hold a certain portion of deposits as their liquidity reserve with the central bank in the form of high-quality liquid assets. Funding liquidity levels fluctuate for banks over time, and there are concerns that high liquidity levels can lead to financial crises. In analysing aggregate financial sector liquidity, Adrian and Shin (2010) note that in order to utilise the excess capacity that comes about from balance sheet growth, financial intermediaries will search for potential borrowers even when borrowers do not have the resources to repay the loan and thus higher levels of aggregate liquidity can cause financial crises. Wagner (2007) theoretically models the relationship between the liquidity of bank assets and banking stability and finds that an increased liquidity of bank assets reduces banking stability during financial crises but not during normal times.
