Climate Change and Financial Stability: The Weather Channel
Climate change could affect banks and the financial systems they anchor through various channels: increasingly extreme weather is one (Financial Stability Board, Basel Committee on Bank Supervision). In our recent staff report, we size up this channel by studying how U.S. banks, large and small, fared against disasters past. We find even the most destructive disasters had insignificant or small effects on bank stability and small and positive effects on bank income. We conjecture that recovery lending after disasters helps stabilize larger banks while smaller, local banks’ knowledge of ...

Flood Risk Outside Flood Zones — A Look at Mortgage Lending in Risky Areas
In support of the National Flood Insurance Program (NFIP), the Federal Emergency Management Agency (FEMA) creates flood maps that indicate areas with high flood risk, where mortgage applicants must buy flood insurance. The effects of flood insurance mandates were discussed in detail in a prior blog series. In 2021 alone, more than $200 billion worth of mortgages were originated in areas covered by a flood map. However, these maps are discrete, whereas the underlying flood risk may be continuous, and they are sometimes outdated. As a result, official flood maps may not fully capture the true ...

Understanding the Linkages between Climate Change and Inequality in the United States
The authors conduct a review of the existing academic literature to outline possible links between climate change and inequality in the United States. First, researchers have shown that the impact of both physical and transition risks may be uneven across location, income, race, and age. This is driven by a region’s geography as well as its ability to adapt. Second, measures that individuals and governments take to adapt to climate change and to transition to lower emissions risk increasing inequality. Finally, while federal aid and insurance coverage can mitigate the direct impact of ...

Financial frictions, real estate collateral, and small firm activity in Europe
We observe significant heterogeneity in the correlation between changes in house prices and the growth of small firms across certain countries in Europe. We find that, overall, the correlation is far greater in Southern Europe than in Northern Europe. Using a simple model, we show that this heterogeneity may relate to financial frictions in a country. We confirm the model?s propositions in a number of empirical analyses for the following countries in Northern and Southern Europe: the United Kingdom, Norway, France, Italy, Spain, and Portugal. Small firms in countries with higher financial ...

Do Mortgage Lenders Respond to Flood Risk?
Using unique nationwide property-level mortgage, flood risk, and flood map data, we analyze whether lenders respond to flood risk that is not captured in FEMA flood maps. We find that lenders are less willing to originate mortgages and charge higher rates for lower LTV loans that face “un-mapped” flood risk. This effect is weaker for high income applicants, as well as non-banks and small local banks. However, we find evidence that non-banks and local banks are more likely to securitize/sell mortgages to borrowers prone to flood risk. Taken together, our results are indicative that ...

How (Un-)Informed Are Depositors in a Banking Panic? A Lesson from History
How informed or uninformed are bank depositors in a banking crisis? Can depositors anticipate which banks will fail? Understanding the behavior of depositors in financial crises is key to evaluating the policy measures, such as deposit insurance, designed to prevent them. But this is difficult in modern settings. The fact that bank runs are rare and deposit insurance universal implies that it is rare to be able to observe how depositors would behave in absence of the policy. Hence, as empiricists, we are lacking the counterfactual of depositor behavior during a run that is undistorted by the ...

The Myth of the Lead Arranger’s Share
We challenge theories that lead arrangers retain shares of syndicated loans to overcome information asymmetries. Lead arrangers frequently sell their entire loan stake—in over 50 percent of term and 70 percent of institutional loans. These selloffs usually occur days after origination, with lead arrangers retaining no other borrower exposure in 37 percent of selloff cases. Counter to theories, sold loans perform better than retained loans. Our results imply that information asymmetries could be lower than commonly assumed or mitigated by alternative mechanisms such as underwriting risk. We ...

Specialization in Banking
Using highly detailed data on the loan portfolios of large U.S. banks, we document that these banks "specialize" by concentrating their lending disproportionately into one industry. This specialization improves a bank’s industry-specific knowledge and allows it to offer generous loan terms to borrowers, especially to firms with access to alternate sources of funding and during periods of greater nonbank lending. Superior industry-specific knowledge is further reflected in better loan and, ultimately, bank performance. Banks concentrate more on their primary industry in times of instability ...

Banking System Vulnerability: Annual Update
A key part of understanding the stability of the U.S. financial system is to monitor leverage and funding risks in the financial sector and the way in which these vulnerabilities interact to amplify negative shocks. In this post, we provide an update of four analytical models, introduced in a Liberty Street Economics post last year, that aim to capture different aspects of banking system vulnerability. Since their introduction, vulnerabilities as indicated by these models have increased moderately, continuing the slow but steady upward trend that started around 2016. Despite the recent ...

Local banks, credit supply, and house prices
I study the effects of an increase in the supply of local mortgage credit on local house prices and employment by exploiting a natural experiment from Switzerland. In mid-2008, losses in U.S. security holdings triggered a migration of dissatisfied retail customers from a large, universal bank, UBS, to homogeneous local mortgage lenders. Mortgage lenders located close to UBS branches experienced larger inflows of deposits, regardless of their investment opportunities. Using variation in the geographic distance between UBS branches and local mortgage lenders as an instrument for deposit growth, ...
