We summarize and evaluate Fannie Mae and Freddie Mac's credit risk transfer (CRT) programs, which have been used since 2013 to shift a portion of credit risk on more than $1.8 trillion of mortgages to private sector investors. We argue that the CRT programs have been successful in reducing the...

The financial crisis of 2007-09 has sparked keen interest in models of financial frictions and their impact on macro activity. Most models share the feature that borrowers suffer a contraction in the quantity of credit. However, the evidence suggests that although bank lending contracted during...

There is substantial heterogeneity in the structure of trading relationships in the U.S. overnight interbank lending market: Some banks rely on spot transactions, while most form stable, concentrated borrowing relationships to hedge liquidity needs. As a result, borrowers pay lower prices and...

Interbank markets for term maturities experienced great stress during the 2007-09 financial crisis, as illustrated by the behavior of one- and three-month Libor. Despite widespread interest in these markets, little data are available on dollar interbank lending for maturities beyond overnight....

Liquidity hoarding by banks and extreme volatility of the fed funds rate have been widely seen as severely disrupting the interbank market and the broader financial system during the 2007-08 financial crisis. Using data on intraday account balances held by banks at the Federal Reserve and...

We identify and track over time the factors that make the financial system vulnerable to fire sales by constructing an index of aggregate vulnerability. The index starts increasing quickly in 2004, before most other major systemic risk measures, and triples by 2008. The fire-sale-specific...

This paper reviews the mortgage-backed securities (MBS) market, with a particular emphasis on agency residential MBS in the United States.

We provide robust evidence of deviations from the Covered Interest Parity (CIP) relation since the onset of the crisis in August 2007. The CIP deviations exist with respect to different dollar interest rates and exchange rate pairs of the dollar vis-à-vis other currencies. The results show that...

Most mortgages in the U.S. are securitized in agency mortgage-backed securities (MBS). Yield spreads on these securities are thus a key determinant of homeowners' funding costs. We study variation in MBS spreads over time and across securities, and document a cross-sectional smile pattern in MBS...

We employ a unique data set of public commercial real estate (CRE) bonds issued during the Great Depression era (1920-32) to determine their frequency of default and total loss given default. Default rates on these bonds far exceeded those originated in subsequent periods, driven in part by the...
