Bank Failures: The Roles of Solvency and Liquidity
Do banks fail because of runs or because they become insolvent? Answering this question is central to understanding financial crises and designing effective financial stability policies. Long-run historical evidence reveals that the root cause of bank failures is usually insolvency. The importance of bank runs is somewhat overstated. Runs matter, but in most cases they trigger or accelerate failure at already weak banks, rather than cause otherwise sound banks to fail.

Treasury Market Liquidity Since April 2025
In this post, we examine the evolution of U.S. Treasury market liquidity over the past year, which has witnessed myriad economic and political developments. Liquidity worsened markedly one year ago as volatility increased following the announcement of higher-than-expected tariffs. Liquidity quickly improved when the tariff increases were partially rolled back and then remained fairly stable thereafter (through the end of our sample in February 2026), including after the recent Supreme Court decision striking down the emergency tariffs and the subsequent announcement of new tariffs.

Behind the ATM: Exploring the Structure of Bank Holding Companies
Many modern banking organizations are highly complex. A “bank” is often a larger structure made up of distinct entities, each subject to different regulatory, supervisory, and reporting requirements. For researchers and policymakers, understanding how these institutions are structured and how they have evolved over time is essential. In this post, we illustrate what a modern financial holding company looks like in practice, document how banks’ organizational structures have changed over time, and explain why these details matter for conducting accurate analyses of the financial system.

A New Public Data Source: Call Reports from 1959 to 2025
Call Reports are regulatory filings in which commercial banks report their assets, liabilities, income, and other information. They are one of the most-used data sources in banking and finance. In this post, we describe a new dataset made available on the Federal Reserve Bank of New York’s website that contains time-consistent balance sheets and income statements for commercial banks in the United States from 1959 to 2025.

Letters of Recommendation in the PhD Job Market: Lessons from Specialized Banks
Banks must extract useful signals of a potential borrower’s quality from a large set of possibly informative characteristics when making lending decisions. A model that speaks to how banks specialize in lending to an industry in order to better extract signals from data can potentially be applied to a number of real-world scenarios. In this post, we apply lessons from such a model to a topic of timely relevance in economics: job market recommendation letters. Institutions looking to hire new economists must evaluate PhD applicants based on limited and often noisy signals of future performance, including letters of recommendation from these applicants’ advisors or co-authors. Using insights from our model, we argue that the value of these letters depends on who reads them.

Designing Bank Regulation with Accounting Discretion
Why does the banking industry remain prone to large and costly disruptions despite being so heavily regulated? Is there a need for more regulation, less regulation, or simply different regulation? Our recent Staff Report combines insights from academic research in economics, finance, and accounting to provide a deeper understanding of the challenges involved in designing and implementing bank regulation, as well as opportunities for future exploration. This post focuses on the regulation of bank capital, but the ideas are applicable more broadly.

U.S. Banks Have Developed a Significant Nonbank Footprint
In light of the rapid growth of nonbank financial institutions (NBFIs), many have argued that bank-led financial intermediation is on the decline, based on the traditional notion that banks operate to take in deposits and make loans. However, we argue that deposit-taking and loan-making have not accurately characterized U.S. banking operations in recent decades. Instead, as we propose in this post, absent regulatory restrictions, banks naturally expand their boundaries to include NBFI subsidiaries. A significant component of the growth of NBFIs has in fact taken place inside the boundaries of banking firms.

Banking System Vulnerability: 2025 Update
As in previous years, we provide in this post an update on the vulnerability of the U.S. banking system based on four analytical models that capture different aspects of this vulnerability. We use data through 2025:Q2 for our analysis, and also discuss how the vulnerability measures have changed since our last update one year ago.

The Shadow Value of Central Bank Lending
After the Great Financial Crisis, the European Central Bank (ECB) extended its monetary policy toolbox to include the use of long-term loans to banks at interest rates close to zero or even negative. These central bank interventions were aimed at supporting the transmission of expansionary monetary policy and likely played a crucial role in bolstering the financial stability of the euro area, namely by reducing the chance of bank runs. However, quantitative evidence on the effects of these interventions on financial stability remains scant. In this post, we quantify the effectiveness of central bank lending programs in supporting financial stability through the lens of a novel structural model discussed in this paper.

A Historical Perspective on Stablecoins
Digital currencies have grown rapidly in recent years. In July 2025, Congress passed the “Guiding and Establishing National Innovation for U.S. Stablecoins Act” (GENIUS) Act, establishing the first comprehensive federal framework governing the issuance of stablecoins. In this post, we place stablecoins in a historical perspective by comparing them to national bank notes, a form of privately issued money that circulated in the United States from 1863 through 1935.
