The 2023 bank failures, such as Silicon Valley Bank and Signature Bank, demonstrated that a high reliance on uninsured deposits can amplify systemic risk. Uninsured depositors are more likely to withdraw funds rapidly during times of uncertainty, leading to liquidity crises and increasing the likelihood of a bank run.

A is incorrect. While the composition and quality of a bank’s loan portfolio are important, they were not the primary focus in the 2023 failures. The rapid withdrawal of deposits, especially uninsured deposits, was the key factor.

C is incorrect. Profitability is a traditional metric of financial health, but it does not directly correlate with the risk of rapid deposit withdrawals or systemic instability in the way uninsured deposit concentration does.

D is incorrect. The number of branches is not a significant factor in assessing systemic risk. The primary issue during the 2023 failures was related to deposit concentration and depositor behavior, not branch networks.
