AMRO Cafe Seminar: Ready to Run Global Liquidity Stress Tests for Banks and Banking Systems

Liquidity risk remains a persistent threat to financial stability, as starkly demonstrated by the 2023 banking turmoil in the United States and Europe. Hence, the ability to quickly gauge banks’ liquidity risks could prove useful especially during periods of market stress. In this context, our paper introduces a freely available, interactive liquidity stress-testing toolkit for assessing Basel III liquidity coverage ratio-type shocks at the bank and economy level. It covers nearly 13,000 commercial banks across more than 100 economies since 2006, and incorporates pre-calibrated benchmark scenarios, pre-run simulations, and user-defined scenario options. An innovative “breakeven stress factor”—the minimum shock intensity at which a bank’s net liquidity turns negative—is the central output metric. Using the tool, we find meaningful cross-country heterogeneity in liquidity resilience, persistent rank ordering over time, and at least some signalling for institutions that failed in 2023. We also discuss how rising run-off rates in a digitalised world and growing NBFI linkages challenge existing frameworks
