1. Introduction
U.S. housing policy has long promoted homeownership for American households. Major
federal housing programs with this goal include:1


Fannie Mae and Freddie Mac are government sponsored enterprises (GSEs) with a public
mission to support the U.S. mortgage market and private incentives to maximize profits and
shareholder value. The GSEs had outstanding obligations (debt and mortgage backed security
(MBS) guarantees) of over $5.5 trillion at 9/30/2008, just after being placed in a government
conservatorship. Their public mission also includes “housing goals” that provide motivation
for the GSEs to support the mortgage market for lower income households and regions.



The Federal Housing Administration (FHA), created in 1934, operates as an independent
entity within the Housing and Urban Development (HUD) agency to insure home mortgages
for lower income households. The FHA is normally self-supporting, setting its insurance fees
to cover its expected losses. It has been highly successful over its history and has never
required a government subsidy or bailout for its single-family mortgage insurance program.
However, it is facing escalating losses in the aftermath of the mortgage crisis.



The Community Reinvestment Act (CRA) was first passed in 1977 to provide incentives for
banks and thrifts to provide loans and other financial support to lower-income households
and regions. Although the CRA is not generally considered a “housing program” it does
influence mortgage lending alongside the FHA and GSE lower-income programs.



The HUD agency, in addition to the FHA, carries out a wide range of support and subsidy
programs to meet housing needs. HUD’s 2009 fiscal year budget was $38.5 billion.

Quigley and Jaffee (2007) provides a recent review of U.S. housing programs. Quigley and Jaffee (2008) provides
an updated summary, including insights regarding the evolving subprime mortgage crisis. Quigley and Jaffee (2010)
is a forthcoming study that evaluates both the GSE and FHA mortgage credit programs.



Tax expenditures support housing by allowing the deductibility of home mortgage interest
while providing a tax exemption for a homeowner’s implicit rental income and most homesale capital gains. These tax expenditures cost $143 billion for the 2009 fiscal year.

In this paper, I evaluate the role that the housing programs and institutions played in the
financial crisis as requested by the Financial Crisis Inquiry Commission. I do not, therefore,
evaluate these programs in any more general sense, nor do I discuss any current proposals for
regulatory reform.2 I focus on the GSEs (including their housing goals), the FHA, and the CRA. I
exclude the HUD programs (other than the FHA), the federal tax expenditures for home
mortgages, and a miscellany of smaller federal and state housing programs. Of course, any
program that promoted U.S. homeownership and housing investment must bear some
responsibility for the crisis, since it participated in a housing finance system that provided
inadequate controls for sound mortgage underwriting and housing investment. On the other hand,
the HUD programs, tax expenditure policies, and other housing programs have long existed and I
find no evidence that they were focused, or recently modified or expanded, in a manner that
might have particularly encouraged high-risk mortgage lending. As a result, I cannot foresee
empirical methodologies that could attribute any specific quantitative responsibility to them.
1.1 Executive Summary of Primary Conclusions
GSEs. I find the GSEs to have been a significant factor in expanding the mortgage crisis as a
result of their large volume of high-risk mortgage purchases and guarantees. The GSE
public/private hybrid structure created a strong and continuing incentive for such risk-taking, and
a GSE collapse was inevitable. I find that the GSE housing goals for lending to lower-income
households and in lower-income regions were secondary to profits as a factor motivating the
                                                            
2

In other work, Jaffee (2010) and Jaffee and Quigley, I evaluate alternative policies for regulatory reform.

3 
 

GSE investments in high-risk mortgages. However, I recommend further research to determine
which GSE high-risk mortgage features created the highest default propensities, and whether
these features were also a common component of the GSEs’ housing-goal-eligible mortgages.
FHA. I find that the FHA played a minor, and basically irrelevant, role in creating or expanding
the mortgage crisis, as evidenced by its rapidly falling share of total mortgage lending during the
housing bubble. The FHA effectively allowed private lenders and the GSEs to take away its
market, a decision questioned at the time, but hard to fault in retrospect.
CRA. I find no evidence that CRA incentives played a significant role in expanding high-risk
lending during the housing bubble. Of course, as already noted, any program that promotes
mortgage lending to lower-income households will face possible “guilt by association”. Thus I
recommend further empirical tests to determine more precisely the role the CRA may have
played in creating high-risk and undesirable mortgage lending.
Other crisis factors. The GSEs were certainly not alone in creating or expanding the financial
crisis. In my judgment, factors other than housing policy played a more fundamental role in
creating the crisis. These factors include the global savings glut, a monetary policy that
accommodated a major housing bubble, highly leveraged, risky, and lightly regulated bank
investment portfolios, and an unconstrained OTC market for credit default swaps.
1.2 Defining Subprime, Alt-A, and other High-Risk Mortgages
Before turning to the analysis, it is important to review the definitions of subprime, Alt-A,
and other high-risk mortgages. The terms “subprime” and “Alt-A” mortgages are now commonly
used in the press, but they are well defined only with respect to mortgage securitizations for
which the disclosure materials explicitly labeled the mortgage pool as either “subprime” or “AltA”. Securitized subprime mortgage pools were also sometimes described as B or C credits. The

4 
 

term “Alt-A” originally stood for “alternative to agency”, meaning that the mortgages in the pool
had some underwriting defect that made them ineligible for sale to the GSEs. Today, Alt-A
mortgages are judged to exceed subprime in quality, but contain some underwriting defects.
Data for subprime and Alt-A securitized pools have been available from two key sources.
First, the Inside Mortgage Finance publications tabulate the aggregate amount of securitized
subprime and Alt-A mortgage pools. Second, the Loan Performance datasets provide detailed
information on the individual loans that underlie most subprime and Alt-A securitization pools.
If we were only interested in the subprime and Alt-A securitized loans pools, these two data
sources would be adequate.
However, we are also interested in loans with high-risk characteristics that were directly held
in the investment portfolios of the GSEs, banks, and other investors. For these loans, there are no
standard subprime or Alt-A definitions or data sources. The GSEs illustrate the problem. Table 1
shows the subprime, Alt-A, and other high-risk mortgages and mortgage securities that are
recognized in the GSEs’ official reports at 9/30/2009. For example, Fannie Mae’s “Guaranty
Book” is reported to hold $8 billion of subprime mortgages, $259 billion of Alt-A mortgages,
and $591 billion of other high-risk mortgages. The latter category covers loans that are not
explicitly identified as subprime or Alt-A, but nevertheless contain such high-risk characteristics
as low FICO scores, high loan to value ratios, and interest-only/option ARM features. It would
clearly understate the riskiness of Fannie Mae’s guaranty book to focus only on the much smaller
volume of explicitly identified subprime and Alt-A mortgages. Thus, wherever possible in this
paper, I apply high-risk mortgage data that combine the subprime, Alt-A, and other high-risk
categories. A data appendix also provides details on the data sources used for this paper.
We now turn to the analysis of the possible role of the GSEs in the financial crisis.

2. Fannie Mae and Freddie Mac (the GSEs) and the Financial Crisis
From the start of their government conservatorship on 9/07/2008 through the most recent
financial reports (9/30/2009), the two GSEs have required capital infusions from the U.S.
Treasury of $111 billion in order to bring their capital accounts back to zero; in other words, the
two firms lost all of their initial capital plus $111 billion during this period. Their reports further
indicate that most of these losses arise from defaults on the GSEs’ high-risk mortgage positions.
In addition to the direct governmental capital infusion, the U.S. Treasury and Federal Reserve
have now purchased over $1.3 billion of GSE debt and MBS in support of the firms and their
securities.3 These losses and the data in Table 1 confirm that the GSEs participated actively, and
disastrously, in purchasing and guaranteeing a wide range of high-risk mortgages.

A convenient summary of the quantitative support provided by the Treasury and Federal Reserve for capital
investments and market purchases of their debt and MBS are available from the Federal Housing Finance Agency
(2009); see http://www.fhfa.gov/webfiles/15412/TreasFED02192010.pdf

I begin the GSE analysis with a brief review of the GSEs’ role in the U.S. mortgage market
before the advent of subprime lending.
2.1 The GSE Role in the U.S. Mortgage Market
For over three decades, the two GSEs increasingly dominated the U.S. mortgage market,
reaching a major penetration by 2003 of over 50 percent of all U.S. single-family mortgages and
close to 100 percent of all prime, conforming, mortgages. This left private market lenders to
focus on jumbo mortgages (that exceeded the “conforming” limits that restricted the GSEs) and
adjustable rate mortgages (and other more exotic mortgages that existed in small numbers), while
the FHA and CRA-constrained banks provided loans to lower-income borrowers. This
institutional division of labor expanded mortgage market access for both lower-income and
middle-income borrowers. The efficiency of the U.S. mortgage market relies, as well, on tools
and instruments that evolved over many years, including FICO scores and other automated tools
for mortgage underwriting, securitization to facilitate the transfer of the mortgages from “Main
Street” lenders to “Wall Street” investors, and private mortgage insurers that spread the risk on
the higher-risk mortgages.
The traditional business model of the GSEs involves two distinguishable mortgage market
activities. For the first, mortgage securitization, the GSEs purchase mortgages, securitize them,
and then sell the resulting MBS to 3rd party investors. The GSEs provided value-added in the
process because the MBS investors receive a 100% GSE guarantee against any loss of interest or
principal resulting from mortgage borrower defaults. The investors further assumed that the U.S.
Treasury would bail them out if the GSEs were to default on their guarantees; the GSE
guarantees were thus transformed into an “implicit government guarantee”.4 The GSEs charged
                                                            
4

The Treasury/Federal Reserve GSE bailout in September 2008 effectively transformed the “implicit” guarantee
into an explicit one. In other words, the assumption of the GSE investors proved to be correct.

7 
 

an annual “guarantee fee” ranging from 15 to 25 basis points as a percent of the outstanding
volume of the guaranteed MBS. A small capital ratio of 45 basis points, less than one-half
percent, was imposed on the GSEs as a percentage of their outstanding MBS principal balances.
Secondly, the GSEs maintain on-balance-sheet mortgage investment portfolios. Fannie
Mae’s portfolio started long before the widespread use of securitization and both GSE portfolios
have served various purposes historically, including to hold idiosyncratic mortgages that could
not be readily securitized. Over time, the GSEs came to rely on these investment portfolios as
their major profit center. The GSEs funded these portfolios by issuing “agency debt” with
interest rate coupons only slightly above comparable U.S. Treasury bonds--investors believed
these bonds were also protected by the implicit government guarantee. The GSEs earned interest
rate spreads—mortgage yields minus funding costs--on these portfolio positions that commonly
exceeded 100 basis points, making them far more profitable than the 15 to 25 basis point
guarantee fees the GSEs earned on the MBS business line. The GSEs were required to maintain a
2.5 percent capital ratio on the mortgage investment portfolios. A range of expert observers
voiced continuing concerns that these portfolios expanded the GSEs’ risk profile without
providing any significant public benefits.
Figure 1 illustrates the growth of the two GSE business lines, and the GSEs’ evolving share
of the total single-family mortgage market. The solid line (right axis) shows the steady growth in
the GSE share of the U.S. mortgage market, reaching 50.3% of the total market in 2003. The
GSE market share then fell, but began to recover in 2007 as the GSEs expanded their high-risk
mortgage activity, with the GSEs’ total market share reaching its all-time high of 50.9% by the
end of 2008. The two solid bars (left axis) show that the investment portfolio grew the most
rapidly during the 1990s, whereas MBS outstanding grew most rapidly after 2000.

2.2 The GSEs During the Subprime Mortgage Boom
Figure 2 shows that from 2003 to the end of 2006, the GSEs lost approximately 20
percentage points of new business market share. The FHA market share fell as well over this
period, to an almost negligible volume. In contrast, the figure shows an increase of 20-plus
percentage points in the market share of subprime lending based on data from Inside Mortgage
Finance (IMF) and in the market share of high-risk lending based on a special tabulation by Ed
Pinto (currently available only from 2002 to 2007).5 It thus appears that the subprime lending
innovations over this period actively displaced GSE and FHA activity, leading to the declines in
their market shares.6 The major accounting scandals that both GSEs faced and admitted in 2003
and 2004 no doubt added to their inability to respond promptly to the new lending innovations.
At the same time the GSEs were facing a falling market share in the overall U.S. mortgage
market, they were significantly expanding their presence in the market for high-risk mortgages.
This is demonstrated in Table 2:7


Column (1): the dollar amount of GSE high-risk activity generally rises from 2002 to 2007.



Column (5): GSE high-risk activity exceeds 40 percent of total new GSI business after 2003.



Column (6): GSE high-risk activity steadily exceeds 32 percent of total high-risk lending.



Column (7): The GSEs’ portfolio share of high-risk lending (column 5) steadily exceeds the
same ratio for all lenders (column 7).

                                                            
5

The Pinto series is about 10 percentage points higher because it uses a broader definition of high-risk mortgages.
See the data appendix for details on these alternative measures of high-risk mortgages.
6

The high-risk components of the GSE and FHA activity in Figure 2 are also part of the total high-risk loan activity.
The categories not shown in the figure are Veteran Administration loans and non-conforming private market loans.
7

The GSE and aggregate measures of high-risk lending in Table 2 are based on the data from Ed Pinto. See also
footnote 4 and the data appendix. Similar results would be obtained using only publicly released GSE data, such as
already displayed in Table 1and the subprime and Alt-A aggregates available from Inside Mortgage Finance. For
example, see Wallison and Calomiris (2008).

These conclusions are reinforced by the data in Table 3 that show the GSE high-risk
investments growing as a share of their total mortgage activity for various forms of high-risk
mortgages. For example, the share of Fannie Mae’s total mortgage annual acquisitions with a
loan to value ratio (LTV) greater than 90% grew from 7% in 2004 and earlier to 19% in 2007.
For Freddie Mac, the share of its total acquisitions with a current loan to value ratio (CLTV)
expanded from 4% in 2003 and earlier to 37% in 2007. In fact, for both GSEs and for almost all
years and high-risk mortgage characteristics, rising shares are evident through to 2007.

11 
 

The data in both Tables 2 and 3 thus confirm that the GSEs steadily added to their high-risk
mortgage positions and that by 2006/2007 the GSEs’ high-risk mortgage purchases are a
significant share of both the GSEs’ total mortgage acquisitions and the aggregate high-risk
mortgage originations. Wallison and Calomiris (2008) come to a similar conclusion.
The cumulative default rates resulting from the GSEs’ high-risk GSE mortgage activity are
shown in Figures 3 and 4 for Fannie Mae and Freddie Mac respectively. Each curve represents a
particular vintage (year of origination) of high-risk loans, and shows the accumulating default
rate as a function of time since origination. For both GSEs, the 2007 vintage has the highest
default pattern, followed by 2006, and then by 2005. The rising default patterns for vintages
starting with 2005 is not unique for the GSEs. The same pattern is observed for all subprime
mortgage portfolios and is consistent with a general decline in underwriting standards over this
period.8 It represents, however, particularly bad news for the GSEs, since they were steadily
expanding their penetration of the high-risk market over this period, and actually acquired more
than half of all the high-risk mortgages originated in 2007. The GSEs were also holding the
single largest portfolio of high-risk mortgages by 2007.
2.3 The GSE Motivation for Acquiring High-Risk Mortgages
I now consider what motivated the GSEs to acquire large portfolios of high-risk mortgages.
The managements of the GSEs at the time could, of course, provide an answer, and I recommend
that the Commission acquire that information. For the present, I will make the case that GSE
management would have believed that a high-risk mortgage portfolio was in the best interests of
their shareholders while also satisfying their lower-income housing goals.

See Mian and Sufi (2009) and Demyanyk and Van Hemert (2009) for detailed analyses of the observable patterns
in subprime lending, including the concentrated locations of the properties and the observable factors associated
with the highest default rates, including the year of origination.

I begin by noting two sets of information that the GSE managements would have had
available as they expanded their portfolio of high-risk mortgages starting in, say, 2004. Figure 5
shows the foreclosure rates on different classes of mortgage loans as tabulated by the Mortgage
Bankers of America. Standing in 2004, an informed observer would have been well aware of the
serious wave of subprime mortgage foreclosures that peaked in 2001 at over 9%, a level reached
by subprime mortgages again only in 2008. The 2001 peak in foreclosures was the result of the
dot-com recession. The implication is that GSE management would have known by 2004 that
loss rates on subprime and similar high-risk mortgages could be an order of magnitude higher
than the default rates they normally faced on standard portfolios of prime conforming mortgages.
Figure 6 shows an index of affordability, measuring the percentage of homeowners, in this
case, California homeowners, who could afford the median-priced house. A fifty percent index
value is a benchmark value for a sustainable housing market, since it suggests that half of the
households can afford the median-priced house. Even into 2004, California household incomes
were high enough, and California house prices were low enough, to satisfy this condition. By
2005, however, under 30 percent of California households could afford the median house price.
This information should have, and would have, reinforced the GSE management’s recognition
that these were particularly risky times to take on particularly risky mortgages.
Risk-taking had actually been a continuing GSE strategy for almost two decades. In Jaffee
(2003), I document the large amount of interest rate and liquidity risk that the GSEs added as
they rapidly expanded their on-balance sheet mortgage investment portfolios throughout the
1990s; see Figure 1. Any significant interest rate volatility would have created substantial losses
for both firms. It was only the luck of stable interest rates that allowed the GSEs to pass two

15 
 

decades without a major collapse from interest rate volatility.9 Furthermore, since a large part of
their debt was short-term, any significant capital market disruption would have created a
liquidity crisis with the GSEs unable to rollover their maturing debt. Indeed, it was such a
liquidity crisis that created the specific timing of the government’s GSE bailout in 2008.
Risk-taking—whether interest rate risk or credit risk—can maximize the expected benefits
for the GSEs’ management and shareholders because they profit greatly when there are favorable
outcomes, whereas the bondholders (if the GSEs were to become bankrupt), or the taxpayers (if
they bailout the bondholders) suffer the major losses when there are unfavorable outcomes.
Furthermore, the normal deterrence to risk-taking created by bondholder discipline was largely
absent for the GSEs because their bondholders assumed—correctly—that they were protected by
an implicit government guarantee. Finally, the GSE penetration of its primary market for
conforming mortgages had effectively reached 100 percent, so only by expanding to riskier
ventures could the firms had hoped to continue to report growing earnings.
The bottom line is that GSE managers long understood that they and their shareholders
would benefit from risk-taking as long as the higher risks created higher expected returns. To
understand the GSE motivation, of course, does not make it right. As noted above, the GSE
losses have already cost U.S. taxpayers $111 billion, and the ultimate cost could very well be
double or even quadruple that amount. In my view, the GSEs’ high-risk mortgage investments
reflect truly unacceptable decisions by the managers of large financial firms with a public
mission to stabilize mortgage markets, with government in their status, and with almost
unlimited access to low-cost funding based on an implicit guarantee of government support.
While we might hope to receive much more responsible behavior from such managers, I fear this
is the inevitable result of combining a public mission with private profit incentives.

Fannie Mae had actually already faced serious financial losses in the early 1980s from volatile interest rates.

2.4 The Role of the GSEs’ Lower-income Housing Goals
The fundamental GSE disposition toward risk-taking also sheds light on the convenient
complementarity that might allow high-risk mortgages to satisfy both the GSEs’ profit motives
and their Congressional and regulator-imposed housing goals to acquire lower-income
mortgages. Indeed, if the same loans literally satisfy both factors— profitable risk-taking and
lower-income housing goals—then the two factors will be observationally equivalent: empirical
observations will be unable to distinguish them.
That the GSE housing goals are consistent with high-risk mortgage activity, however, does
not imply that the housing goals caused the GSEs’ high-risk activity. Indeed, several factors lead
me to the view that the housing goals were a distinctly secondary priority for GSE management
compared to profits as a factor motivating their investments in high-risk mortgages:


The GSEs failed to meet their housing goals at several points between 2005 and 2008, and
without any significant repercussions from their regulators; see Federal Housing Finance
Agency (2010).



The computations carried out by regulators for setting the goals explicitly exclude the riskiest
categories of subprime mortgages; see Federal Housing Finance Agency (2010).



The consensus of the academic literature is that the affordable housing goals have not
substantially increased homeownership among lower-income families. A key factor is that
the GSEs appear to have “cherry-picked” only the highest quality qualifying loans, loans that
would have been made by other lenders in any case. See Jaffee and Quigley (2007) for
further discussion and citations to the academic literature.

In conclusion, I do not consider the GSE housing goals for lending to lower-income
households and in lower-income regions to have been a primary factor motivating the GSE
investments in high-risk mortgages. However, I recommend further research to determine which
GSE high-risk mortgage features created the highest default propensities, and whether these
features are also a common component of the GSEs’ housing-goals-eligible mortgages.

3. The Federal Housing Administration (FHA) and the Financial Crisis10
The FHA was created under the National Housing Act of 1934 to enhance homeownership
by providing mortgage insurance. It now provides mortgage insurance for five categories: singlefamily homes, multi-family homes, manufactured housing, health care facilities, and home
improvements. In this section, I focus only on the insurance plan operated for single-family
homes, known officially as the Mutual Mortgage Insurance (MMI) fund.
The response of the FHA during the housing boom/bubble leading to the financial crisis is
just the opposite of that just described for the GSEs: while the GSEs significantly expanded their
high-risk mortgage activity as the housing boom expanded, the FHA virtually ceased to operate
at all. This is illustrated in Figure 2, which shows the FHA share of the overall mortgage market
steadily declining from 2000 to 2006 and with only a small upward move in 2007. Specifically,
in 2006 the FHA endorsed (insured) just $54 billion of new mortgages representing just 1.8% of
the total mortgage originations in that year. Even in 2007, the FHA endorsed only $80 billion of
new mortgages, representing 3.3% of total mortgage originations in that year. In contrast, in
2009, the FHA endorsed about 20% of the total mortgage originations, in line with its market
shares in some earlier periods before the advent of subprime lending.
The dramatic decline of FHA activity over the same period that high-risk mortgages are
dramatically expanding is a function of two fundamental factors. First, the FHA faced
unprecedented competition from both private subprime lenders and from the GSEs. The terms
and conditions on these private market and GSE high-risk mortgages appeared more favorable
than the terms required on FHA mortgages, and borrowers made the sensible decision to go with
the more favorable alternative. Of course, some of the subprime contracts were too good to be

See Jaffee and Quigley (2007) for a general discussion of the FHA and Jaffee and Quigley (2010) for an updated
discussion of its role in the subprime crisis. See also Weicher (2006) for further background on the FHA and FHA
(2009) for the FHA’s most recent annual report released in November 2009..

true—reflecting predatory lending11—but even when the contract terms were fairly disclosed, it
appears the FHA contracts were often simply not competitive.
Second, the FHA proved both unable and unwilling to modify its standard contracts to
compete in the marketplace against the newly available subprime and Alt-A contracts. The
“unable” is the result of a complex administrative situation that requires the FHA to acquire
Congressional agreement before it can introduce a new contract. The “unwilling” reflects a longstanding FHA disposition to respond slowly, if at all, to changing market conditions. Whether
this reflects fiduciary respect for the taxpayers’ money or bureaucratic inertia, the FHA is
certainly slow to change.
My conclusion is that the FHA played a minor, and basically irrelevant, role in creating or
expanding the mortgage crisis, as evidenced by its rapidly falling share of total mortgage lending
during the housing bubble. The FHA effectively allowed private lenders and the GSEs to take
away its market, a decision questioned at the time, but hard to fault in retrospect.
As a postscript to this conclusion, I note that in its annual report FHA (2009), the FHA

confirms that it is currently in violation of its capital requirements as a result of the accumulating
losses on mortgages that had been insured prior to 2009. This is not surprising since, as shown in
Figure 6, the foreclosure rate on FHA mortgages has been rising. There is, fortunately, also good
news. First, the FHA recently announced new higher insurance premiums and contract terms that
reflect its resolve to maintain its long-term record of financial soundness; see Stevens (2010).
Second, the FHA still maintains sufficient insurance reserves, in addition to its capital, to cover
its expected losses, although, of course, these losses could escalate unexpectedly depending on
the future course of housing prices and general economics conditions.

I am hopeful the Federal Reserve’s July 2008 Truth in Lending additions will eliminate any such future behavior.

4. The Community Reinvestment Act (CRA) and the Financial Crisis
A determination of the role of the CRA in the financial crisis is substantially more difficult
than for the GSEs or the FHA. One problem is that the CRA is not associated with any specific
enterprise (such as the GSEs) or agency (such as the FHA), with the result that no single data
source is available to quantify its results. A second problem is that the CRA does not stipulate
specific goals or targets for lending or investments. A third problem is that the incentives the
CRA does create for mortgage lending are only one of numerous actions a bank may take to earn
CRA credits. Thus, while CRA credit could in principle be the factor that induced a bank to
invest in high-risk mortgages for lower-income borrowers, it is equally possible that little if any
of its high-risk mortgage activity was so motivated.
Fortunately, empirical evidence is available that may allow a preliminary opinion. The key
quantitative evidence is provided in a recent Federal Reserve study by Canner and Bhutta (2008)
with the explicit goal to evaluate the evidence whether the CRA contributed in a substantive way
to the financial crisis.12 Their key findings are:


The CRA requires banks to extend CRA loans within the norms of safe and sound operation.



The CRA does not cover non-bank lenders, such as mortgage and finance companies, so their
active participation in subprime lending occurred without any CRA incentives.



Only 6 percent of identified subprime mortgages in 2006 were made to CRA-qualified
borrowers or neighborhoods by CRA-covered institutions.



For loans originated between January 2004 and April 2008, the observed 90-day delinquency
rates are actually slightly lower in zip codes that are CRA-qualified than for zip codes with
median incomes that are just sufficiently higher to make them CRA-unqualified.

Canner and Bhutta conclude, “Taken together, the available evidence to date does not lend
support to the argument that the CRA is a root cause f the subprime crisis.” Randall Kroszner
                                                            
12

A study using a similar methodology and data by Traiger and Hinckley (2008) arrives at very similar results.

20 
 

(2008), a member of the Board of Governors of the Federal Reserve, in a major speech also
endorsed the Canner and Bhutta study and further noted that previous Federal Reserve reports to
Congress have indicated that CRA loans to lower-income borrowers have been nearly as
profitable and performed similarly to comparable loans by the same institution.13
A long-standing academic literature that studies the mortgage market influences of the CRA
is also available. Gabriel and Rosenthal (2009) is the most recent example with ample references
to the existing literature. They apply the same “over and under income” zip code methodology as
just noted in Canner and Bhutta, but with the primary intent to determine the possible
interactions between the GSE housing goals and the CRA incentives. They find little evidence of
any impact of the GSE housing goals on eligible communities, and while they do find a CRA
impact, it is only for loans larger than the GSE conforming limits, and it is to a smaller degree
than they had anticipated. Gabriel and Rosenthal conclude:
“…on balance, the lack of more compelling evidence of GSEA and CRA effects on mortgage
lending and home ownership rates among targeted underserved tracts is striking …”

My conclusion is that the available evidence provides no indication that CRA incentives
played a significant or unique role in expanding high-risk lending during the housing bubble. To
be clear, I have not attempted to evaluate the costs and benefits of the CRA in any broader
context. Furthermore, as already noted, any program that promotes mortgage lending to lowerincome households will face at least claims of “guilt by association”. Thus I endorse any further
empirical tests that could determine more precisely any role the CRA may have played in
creating or extending the recent rounds of high-risk and undesirable mortgage lending.

                                                            
13

See Avery, Bostic, Calem and Canner (1996) and Laderman (2004)), as well the references they cite, for a
discussion of the continuing Federal Reserve research that finds CRA loans have performed acceptably well.

5. Concluding Comments
This paper has evaluated the role that the GSEs, FHA, and CRA played in the financial crisis.
It has not, however, attempted an overall evaluation of any or all U.S. housing policies, nor has it
considered any policies for regulatory reform. The main conclusions are:14


I find the GSEs to have been a significant factor in expanding the mortgage crisis as a result
of their high volume of high-risk mortgage purchases and guarantees. Furthermore, I find
that the GSE housing goals for lending to lower-income households and in lower-income
regions were secondary to profits as a factor motivating the GSE investments in high-risk
mortgages.



I find that the FHA played a minor, and basically irrelevant, role in creating or expanding the
mortgage crisis, as evidenced by its rapidly falling share of total mortgage lending during the
housing bubble.



I find no evidence that CRA incentives played a significant or unique role in expanding highrisk lending during the housing bubble. The CRA is open, however, to claims of “guilt by
association”, and thus I endorse any further empirical tests that could determine more
precisely any role the CRA may have played in creating or extending the recent rounds of
high-risk and undesirable mortgage lending.

It is important to recognize in concluding that factors other than housing policy likely played
a more fundamental role in creating the financial crisis and might well be on par with the GSEs
in expanding the crisis. These factors include the global savings glut, a monetary policy that
accommodated a major housing bubble, highly leveraged, risky, and lightly regulated bank
investment portfolios, and an unconstrained OTC market for credit default swaps.

In other work, Jaffee (2010) and Jaffee and Quigley (2010), I evaluate alternative policies for regulatory reform.
