The US Banking Sector since the March 2023 Turmoil

In March 2023, the US banking sector turmoil sent a shockwave through the global financial system.Silicon Valley Bank (SVB), the 16th largest bank in the country, collapsed in a matter of days, followed by Signature Bank (SBNY) and First Republic Bank (FRB), marking the largest bank failures after Washington Mutual Bank in 2008.Triggered by sizable deposit outflows, this event raised concerns about the soundness of the rest of the US banking sector, in particular, other banks of similar or smaller size with large amounts of uninsured deposits, unrealized losses, and commercial real estate exposures.The March turmoil is a powerful reminder of the challenges posed by the interaction between tighter monetary and financial conditions and the buildup in vulnerabilities-challenges amplified by ineffective interest, liquidity, and credit risk management practices at some banks.This note offers an analysis of the main attributes of the affected banks to assess the extent to which vulnerabilities persist in a weak tail of banks. 1 Furthermore, the note provides a prospective assessment by evaluating the medium-term risks to financial stability posed by this weak tail.1 SVB, SBNY, and FRB were considered large banking organizations given the size of their balance sheets according to the Federal Reserve's supervisory classification.However, market participants qualified them as super-regional banks because they were larger than community banks and smaller than the largest banks in the United States.For more details, Federal Reserve Board -Approaches to Bank Supervision.
