GSE guarantees, financial stability, and home equity accumulation
Before 2008, the government?s ?implicit guarantee? of the securities issued by the government-sponsored enterprises (GSEs) Fannie Mae and Freddie Mac led to practices by these institutions that threatened financial stability. In 2008, the Federal Housing Finance Agency placed these GSEs into conservatorship. Conservatorship was intended to be temporary but has now reached its tenth year, and policymakers continue to weigh options for reform. In this article, the authors assess both implicit and explicit government guarantees for the GSEs. They argue that adopting a legislatively defined ...

Investor Demands for Safety, Bank Capital, and Liquidity Measurement
We construct a model of a bank's optimal funding choice, where the bank negotiates with both safety-driven short-term bondholders and (mostly) risk-taking long-term bondholders. We establish that investor demands for safety create a negative relationship between the bank's capital choices and short-term funding, as well as negative relationships between capital and common measures of bank liquidity. Consistent with our model, our bank-level empirical analysis of these capital-liquidity tradeoffs show (1) that bank liquidity measures have a strong and negative relationship to its capital ratio ...

Distribution of Credit Risk Among Providers of Mortgages to Lower-Income and Minority Homebuyers
Which institutions bear the credit risk for mortgage lending to lower-income and minority borrowers and in lower-income and predominantly minority neighborhoods? In seeking to answer those questions, the authors went beyond looking at mortgage credit risk in terms of numbers or amounts of loans and developed measures based on factors that affect the riskiness of loans, including loan-to-value ratios and associated default and loss severity rates. In 1995, a nonprofit government mortgage insurer, the Federal Housing Administration, was the major bearer of credit risk for mortgage lending to ...

Federal Home Loan Bank advances and commercial bank portfolio composition
The primary mission of the 12 cooperatively owned Federal Home Loan Banks (FHLBs) is to provide their members financial products and services to assist and enhance member housing finance. In this paper, we consider the role of the FHLBs' traditional product--"advances," or collateralized loans to members--in stabilizing commercial bank members' residential mortgage lending activities. ; Our theoretical model shows that using membership criteria (such as a minimum of 10 percent of the portfolio being in mortgage-related assets) or using mortgage-related assets as collateral does not ensure ...

The Community Reinvestment Act and the profitability of mortgage-oriented banks
The Community Reinvestment Act (CRA) requires lenders "to help meet the credit needs of the local communities in which they are chartered, consistent with the safe and sound operation of such institutions.'' For proponents of efficient markets, the CRA is a threat to lender profitability. For others, the CRA has the potential to increase profitability. We examine the relative profitability of commercial banks that specialize in mortgage lending in lower-income neighborhoods or to lower-income borrowers using three different techniques, and find that lenders active in lower-income ...

The GSE implicit subsidy and the value of government ambiguity
The housing-related government-sponsored enterprises Fannie Mae and Freddie Mac (the "GSEs") have an ambiguous relationship with the federal government. Most purchasers of the GSEs' debt securities believe that this debt is implicitly backed by the U.S. government despite the lack of a legal basis for such a belief. In this paper, I estimate how much GSE shareholders gain from this ambiguous government relationship. I find that (1) the government's ambiguous relationship with Fannie Mae and Freddie Mac imparts a substantial implicit subsidy to GSE shareholders, (2) the implicit government ...
Working Paper
GSEs, mortgage rates, and secondary market activities
Fannie Mae and Freddie Mac are government-sponsored enterprises (GSEs) that purchase mortgages and issue mortgage-backed securities (MBS). In addition, the GSEs are active participants in the primary and secondary mortgage markets on behalf of their own portfolios of MBS. Because these portfolios have grown quite large, portfolio purchases as well as MBS issuance are likely to be important forces in the mortgage market. This paper examines the statistical evidence of a connection between GSE actions and the interest rates paid by mortgage borrowers. We find that both portfolio purchases and ...
