The rescue of Fannie Mae and Freddie Mac
We describe and evaluate the measures taken by the U.S. government to rescue Fannie Mae and Freddie Mac in September 2008. We begin by outlining the business model of these two firms and their role in the U.S. housing finance system. Our focus then turns to the sources of financial distress that the firms experienced and the events that ultimately led the government to take action in an effort to stabilize housing and financial markets. We describe the various resolution options available to policymakers at the time and evaluate the success of the choice of conservatorship, and other actions ...

How Resilient Is Mortgage Credit Supply? Evidence from the COVID-19 Pandemic
We study the evolution of US mortgage credit supply during the COVID-19 pandemic. Although the mortgage market experienced a historic boom in 2020, we show there was also a large and sustained increase in intermediation markups that limited the pass-through of low rates to borrowers. Markups typically rise during periods of peak demand, but this historical relationship explains only part of the large increase during the pandemic. We present evidence that pandemic-related labor market frictions and operational bottlenecks contributed to unusually inelastic credit supply, and that ...

Intermediation Frictions in Debt Relief: Evidence from CARES Act Forbearance
We study the role of mortgage servicers in implementing the CARES Act mortgage forbearance program during the COVID-19 pandemic. Despite universal eligibility,we document that a significant number of federally backed mortgage borrowers be-come delinquent during the pandemic without successfully entering into a forbearance program, and that the relative frequency of these "missing" forbearances varies significantly across mortgage servicers for otherwise identical loans. Forbearance out-comes are systematically related to servicer characteristics including size, liquidity and ...

Why is the market share of adjustable-rate mortgages so low?
Over the past several years, U.S. homebuyers have increasingly favored fixed-rate mortgages over adjustable-rate mortgages (ARMs). Indeed, ARMs have dropped to less than 10 percent of all residential mortgage originations, a near-record low. One might speculate that the decline in the ARM share has been driven by ?one-off? factors relating to the financial crisis. However, a statistical analysis suggests that recent trends can largely be explained by the same factors that have historically shaped mortgage choice?most notably, the term structure of interest rates and its effects on the ...

TBA trading and liquidity in the agency MBS market
Mortgage-backed securities in the United States are generally traded on a ?to-be-announced,? or TBA, basis. The key feature of a TBA trade is that the identity of the securities to be delivered to the buyer is not specified exactly at the time of the trade, facilitating a liquid forward market. This article describes the main features of the TBA market. It also presents evidence on the liquidity of this market during the financial crisis period. Using variation in TBA eligibility rules, the authors? estimates suggest that the liquidity benefits associated with the TBA market are of the order ...

Credit risk transfer and de facto GSE reform
The Fannie Mae and Freddie Mac credit risk transfer (CRT) programs, now in their fifth year, shift a portion of credit risk on more than $1.8 trillion of mortgages to private-sector investors. This study summarizes and evaluates the CRT programs, finding that they have been successful in reducing the exposure of the government-sponsored enterprises and the federal government to mortgage credit risk without disrupting the liquidity or stability of mortgage secondary markets. The programs have also created a new financial market for pricing and trading mortgage credit risk, which has grown in ...

Peas in a pod? Comparing the U.S. and Danish mortgage finance systems
Like the United States, Denmark relies heavily on capital markets for funding residential mortgages, and its covered bond market bears a number of similarities to U.S. agency securitization. This article describes the key features of the Danish mortgage finance system and compares and contrasts them with those of the U.S. system. In addition, it highlights characteristics of the Danish model that may be of interest as the United States considers further mortgage finance reform. In particular, the Danish system includes features that mitigate refinancing frictions during periods of falling ...
