Financial institution Failures: The Roles of Solvency and Liquidity


Financial institution Failures in america, 1863–2024

 Line chart tracking the history of bank failures in the U.S. by percentage (vertical axis) from 1863 to 2024 (horizontal axis) for national banks (red), FDIC member banks (blue), and bank failures with deposit outflows greater than 7.5% (gray); bank failures have occurred in repeated waves throughout the timespan depicted.
Supply: “Financial institution Failures: The Roles of Solvency and Liquidity,” Correia, Luck, and Verner (2026a).

Financial institution Failures: The Concept

Financial institution failures can stem from two associated however distinct sources. Below the liquidity view, a sudden wave of withdrawals forces a financial institution to liquidate property at fire-sale reductions, rendering it bancrupt. Runs can thus set off the failure of in any other case wholesome banks (Diamond and Dybvig, 1983) or of weak however nonetheless solvent banks (Goldstein and Pauzner, 2005).

Below the solvency view, losses on loans or investments erode a financial institution’s fairness. As soon as financial institution property should not price sufficient to completely repay depositors, the financial institution is essentially bancrupt. A run might then be the ultimate set off that forces closure. The run can decide when and the way the financial institution fails, however it’s not the basis reason behind the issue.

Financial institution Failures: The Proof

Discovering 1: Financial institution failures are at all times and in all places associated to weak financial institution fundamentals.

The controversy over whether or not financial institution failures are brought on by insolvency or illiquidity has a protracted historical past. In A Financial Historical past of america, Friedman and Schwartz (1963) argued that many financial institution failures throughout the Nice Melancholy resulted from “self-justifying” runs on solvent banks. Nevertheless, subsequent empirical work has positioned extra emphasis on poor financial and bank-level fundamentals. Research utilizing regional and bank-level knowledge discover that banks that failed throughout the Melancholy had been extra uncovered to declining native financial circumstances, had been much less nicely capitalized, held extra illiquid property, and relied extra on wholesale funding than surviving banks (White 1984, Calomiris and Mason 2003).

The essential function of poor financial institution fundamentals extends nicely past the Nice Melancholy. In a current paper, we prolong these findings throughout 160 years of U.S. banking knowledge, protecting over 5,000 financial institution failures (Correia, Luck, and Verner, 2026b). Failing banks constantly exhibit declining earnings and capitalization, rising asset losses, and rising reliance on costly funding within the years earlier than failure. A typical precursor to failure is fast asset development, often from aggressive lending. These patterns maintain for financial institution failures with and with out runs. Additionally they maintain throughout institutional regimes with and with out deposit insurance coverage or a public lender of final resort. Consequently, financial institution failures are considerably predictable based mostly on weak financial institution fundamentals. Extra broadly, crises by which many banks fail are sometimes a predictable consequence of deteriorating fundamentals.

Discovering 2: Restoration charges counsel most, however not all, failed banks topic to runs had been essentially bancrupt.

Are most failures brought on by runs on weak-but-solvent banks or on essentially bancrupt financial institution? Restoration charges on failed financial institution property present new insights into this query. Earlier than the introduction of federal deposit insurance coverage in 1934, general collectors recovered, on common, solely 75 cents on the greenback, whereas unsecured depositors recovered solely 66 cents on the greenback (Correia, Luck, and Verner 2026a, 2026b). Because of this failed financial institution property fell considerably in need of protecting debt claims, indicating that the majority failed banks had been essentially bancrupt. Runs on weak-but-solvent banks due to this fact accounted for less than a modest share of nationwide financial institution failures, until one assumes that receivership itself destroyed substantial worth. Whereas runs had been an vital set off of failure at bancrupt banks, low restoration charges counsel they had been much less usually the reason for failure for in any other case solvent banks.

Discovering 3: Financial institution examiners emphasize poor asset high quality and barely attribute failures to runs.

What do financial institution examiners say concerning the situation of failed banks and the causes of financial institution failure? Within the pre-deposit-insurance U.S. banking system, OCC examiners’ assessments point out that the majority failed banks held property uncovered to substantial losses. On common, examiners categorized solely 36 % of failed financial institution property as “good,” whereas 47 % had been thought-about “uncertain” and 18 % “nugatory.”

Moreover, U.S. financial institution examiners traditionally categorized the reason for loss of life for banks. Within the OCC’s bank-specific cause-of-failure experiences, the commonest causes had been poor native financial circumstances, asset losses, and fraud. Runs and liquidity points had been cited in fewer than 20 out of over 2,000 circumstances.

The Nice Melancholy is a partial exception. Federal Reserve Board’s classifications of Melancholy-era suspensions counsel that liquidity points performed a bigger function than in different durations (Richardson 2007). However even then, examiners’ assessments remained pessimistic about asset high quality. As a 1936 Federal Reserve report put it, “In our lengthy, failure-studded historical past of banking, a lot of the establishments which suspended enterprise had been subsequently proved to be bancrupt.”

Discovering 4: Robust banks often survive runs by way of varied mechanisms, together with interbank cooperation, suspension, and examination.

Why don’t runs trigger solvent banks to fail? A part of the reply is that runs are extra frequent at weak banks. However robust banks do generally expertise runs (Correia, Luck, and Verner 2026c). These runs not often result in failure as a result of robust banks can make use of a number of mechanisms to keep away from expensive failure.

First, in some circumstances, house owners would supply money to credibly sign confidence of their financial institution, very similar to how George Bailey stops the run in It’s a Fantastic Life. Second, interbank lending can present wanted liquidity, as banks are sometimes higher knowledgeable a couple of peer’s true situation (Blickle, Brunnermeier, and Luck 2024). Third, within the historic U.S. banking system, clearinghouses acted as quasi-central banks, issuing mortgage certificates to offer liquidity. Lastly, throughout extreme runs, banks would quickly droop convertibility, each to chill panics and to permit examiners to audit their monetary statements and assess solvency. Collectively, these mechanisms scale back the scope for runs to pressure wholesome banks into expensive failure.

Coverage Implications

The discovering that the majority financial institution failures stem from solvency issues has vital implications for monetary stability coverage.

Deposit insurance coverage, launched on the federal degree with the creation of the FDIC in 1933, sharply decreased failures with runs. Nevertheless, as a result of pre-FDIC failures had been not often brought on by runs on wholesome banks, deposit insurance coverage has not eradicated waves of financial institution failures altogether. What it did change was the best way banks fail. Within the absence of depositor self-discipline, financial institution failure is now extra usually the results of supervisory interventions (Correia, Luck, and Verner 2025). This framework reduces the incidence of probably expensive runs, however it additionally reduces the ex publish self-discipline that runs impose on bancrupt banks. With out this self-discipline, there’s extra onus on supervisors to determine potential bancrupt banks after which to mitigate the related losses over time.

Lender-of-last-resort coverage also can assist solvent banks survive panics. A pure experiment from the Melancholy, evaluating the Atlanta Fed’s beneficiant lending with the St. Louis Fed’s extra restrictive strategy, reveals that liquidity assist can scale back failures (Richardson and Troost, 2009). However liquidity provision can’t repair insolvency. Worldwide proof reveals that even banking misery with out financial institution runs can produce extreme contractions in credit score and output (Baron, Verner, and Xiong, 2021). Likewise, focused liquidity interventions within the twenty first century have by no means resolved financial institution misery on their very own; balance-sheet restructuring was at all times required (Kelly et al., 2025).

If most financial institution failures are finally pushed by insolvency, then greater fairness capital performs a key function in making the banking system extra resilient (Admati and Hellwig 2014). Higher capitalization reduces each the chance of failure and the scope for runs to trigger harm. Efficient supervision additionally performs a central function by making certain that banks acknowledge losses and by figuring out when recapitalization is required. In crises rooted in weak solvency, recapitalization is arguably the best solution to restore confidence within the banking system.

Summing Up

The long-run proof on financial institution failures factors in a single course: Financial institution failures often start with unhealthy property, weak earnings, and deteriorating solvency. Runs can speed up failure and worsen the harm, however by the point depositors head for the exit, the deeper downside is often baked into financial institution steadiness sheets. Historical past has proven that making certain banks are funded with enough capital and avoiding reckless lending booms are essentially the most dependable methods to forestall failures from reaching that stage.
