This risk, which materialized following the rapid rise in interest rates that began in early 2022, underscores the importance of monitoring the vulnerabilities of the banking system. In this post, as in previous years, we provide an update of four analytical models aimed at capturing different aspects of vulnerability of the U.S. banking system, with data through the second quarter of 2023. In addition, we discuss changes made to the methodology based on the lessons from March 2023 and assess how the system-level vulnerability has evolved.
