Discussion of “Systemic Risk and the
Solvency-Liquidity Nexus of Banks”

Author: Tobias Adrian

Pierret (2015) presents empirical analysis of the solvency-liquidity nexus for the banking system, documenting that a shock to the level of banks’ solvency risk is followed by lower short-term debt. Conversely, higher short-term debt Granger-causes higher solvency risk. These results point toward a tight interaction between solvency and liquidity risk over time. My comments are threefold. First, I suggest improving the identification of shocks in Pierret’s vector autoregressive setup. Second, I caution against using the quantitative results as the basis for setting policy. Third, I recommend using theoretical restrictions from macro-finance theories to improve identification and interpretation.
