The Federal Housing Finance Agency (FHFA) will soon re-propose a rule to implement a new regulatory capital framework for Fannie Mae and Freddie Mac, the government-sponsored enterprises (GSEs) that remain in government conservatorship. The new proposal would supersede the 2018 capital rule that was proposed under Mel Watt, the Obama-appointed predecessor of the current FHFA Director, Mark Calabria.REF The 2018 proposal was announced prior to the FHFA’s efforts to get Fannie and Freddie out of government conservatorship, and the GSEs’ capital requirements remain suspended, so a new proposal is warranted. The new proposal, likely to be released by spring 2020, will not represent the first time that federal regulators have imposed a risk-based capital framework on Fannie and Freddie.
The details of the new proposal remain unclear, but Calabria has frequently drawn attention to the large disparity in capital ratios between the GSEs and the nation’s largest banks, while also stating that Fannie and Freddie should “maintain capital levels commensurate with their risk profiles.”REF Thus, it appears that the new proposal will move the GSEs’ capital framework closer to the type of capital rules imposed on large U.S. banks. This Backgrounder summarizes the 2018 capital proposal and offers suggestions for making the GSEs’ new risk-based capital framework stronger. In particular, the FHFA should strengthen the framework by relying on simple metrics that force Fannie and Freddie to operate with capital ratios and reserves similar to those of the nation’s largest banks and mortgage insurance companies.
Overview of Risk-Based Capital Framework
In 1988, federal banking regulators adopted risk-based capital requirements for U.S. commercial banks. These requirements were based on the first iteration of the Basel Accords, an international agreement reached through the Basel Committee on Banking and Supervision.REF Banking regulators currently enforce the third version—Basel III—of the Basel rules, but the overall framework is essentially unchanged.REF The basic idea is that banks have to meet several different capital ratios using their risk-weighted assets rather than their total assets. For instance, banks have to meet a total capital to risk-weighted asset ratio of 8 percent.REF
As the (simplified) example in Table 1 shows, the weights applied to various assets increase with the assets’ level of perceived risk. As a result, banks have to raise relatively less capital for assets that regulators deem safer. Cash and U.S. Treasury securities, for example, are deemed risk-free, so banks do not have to raise any capital to absorb losses associated with holding either of these assets. Commercial loans, on the other hand, receive a risk weight of 100 percent because they are much riskier than either cash or Treasuries. Finally, single-family home mortgages receive a 50 percent risk weight because they are deemed to be half as risky as commercial loans.
In this example, the bank holds $10,000 in commercial loans, so it must include the full $10,000 in its risk-weighted assets ($10,000 * 1.0). While the bank is not required to include any of its cash or Treasuries in its risk-weighted assets, the bank must include $2,000 of its home mortgages ($4,000 * 0.50) in its risk-weighted assets. As the last column of Table 1 shows, the bank then multiplies 8 percent—its minimum capital requirement—by these risk-weighted asset figures to determine how much capital it must raise (its capital charge) for each asset category.
Thus, the bank must raise $1,040 in capital to meet its minimum requirement ($13,000 * 8 percent). If, alternatively, all the assets received a risk weight of 1 (100 percent), then the bank would have to raise capital for 100 percent of its assets, requiring total capital of $1,840 ($23,000 * 8 percent). Thus, for any given required ratio, a bank has to raise less capital when regulators determine that certain assets should have a risk weight of less than 1.REF This example provides the basic mechanics of the risk-based capital framework that U.S. banks must follow, but the complete set of requirements is much more detailed.
The framework for the largest U.S. banks, for example, includes minimum requirements based on several different measures of capital, such as tier 1 capital, common equity tier 1 capital, and tier 2 capital.REF In addition to meeting minimum capital ratios based on these different measures, the largest U.S. banks have to meet (among others) a liquidity coverage ratio,REF a supplemental leverage ratio (SLR) that broadly accounts for off-balance-sheet exposures, and a capital conservation buffer (CCB).REF Failure to meet the SLR and CCB requirements trigger restrictions on capital distributions, so both serve as de facto higher minimum-leverage requirements.REF
While such a complex framework with many different risk weights gives the appearance of capital precisely tailored to match various risks, regulators have little choice but to develop weights based (at least partly) on previous loss experiences. Therefore, a framework with a single risk weight—even a weight of 1, where all assets are weighted equivalently—can be adjusted to target any desired capital level just as effectively. Still, even with the level of complexity in the FHFA’s 2018 capital proposal, it is clear that bank-like capital requirements can easily be formulated to apply to Fannie Mae and Freddie Mac.
Summary of FHFA’s 2018 Capital Proposal
After the federal government placed Fannie Mae and Freddie Mac in government conservatorship in 2008, the FHFA suspended the companies’ regulatory capital requirements. In 2017, the FHFA implemented the Conservatorship Capital Framework (CCF), an “aligned risk measurement framework” that was designed to ensure that Fannie and Freddie would operate prudently while in conservatorship.REF The FHFA then used the CCF as the foundation for its 2018 risk-based capital proposal, a plan that was released to “provide transparency to all stakeholders about FHFA’s supervisory view on this topic.”REF In other words, the 2018 proposal is essentially a hypothetical capital framework, one that could have been implemented if the FHFA had lifted the suspension of the firms’ capital requirements.
The 2018 proposal, like other risk-based capital regimes, is designed to impose risk-based capital charges tailored to the risk of specific assets. Because the majority of Fannie’s and Freddie’s assets are related to home mortgages, a main goal of the 2018 proposal is to tailor capital charges to the various types of mortgage loans that the companies purchase. The proposal also seeks to tailor capital charges to the companies’ market risk (the financial risk associated with holding different types of assets in a portfolio), credit risk (the risk that borrowers and creditors might not meet their financial obligations), and operational risk (the risk of the ongoing business of guaranteeing securities). To appropriately tailor risk, the framework uses a variety of methods to develop weights and multipliers that are then used to estimate these risk components.
The proposal establishes three approaches to determining the GSEs’ market-risk capital. However, the FHFA gives this type of risk relatively little weight because “the Enterprises’[Fannie’s and Freddie’s] retained portfolio activities have been greatly limited through conservatorship.”REF To determine the risk-based credit-risk requirement, the proposed framework starts by segmenting mortgage credit risk into the following three categories: expected loss (the borrowers’ failure to meet mortgage obligations during stable housing market conditions), unexpected loss (the borrowers’ failure to make mortgage payments during a stressful event, such as a housing market downturn or a recession), and catastrophic loss (any losses beyond unexpected losses that are deemed highly unlikely to occur).REF This scheme requires someone to forecast losses under stress conditions, so the FHFA does so using methods similar to those used to predict such losses for large banking institutions.REF The FHFA then calculates a series of risk factors based on individual loan characteristics, such as loan-to-value and credit score.REF
For the operational-risk component, the FHFA uses the Basel Basic Indicator Approach to require Fannie and Freddie to take a capital charge of eight basis points times the unpaid principal balance of all assets and guarantees with credit risk.REF Independent of these requirements, the proposal includes a going-concern buffer, a fixed capital charge designed to require capital sufficient to support operations after “a period of severe financial stress.”REF Using Fannie’s and Freddie’s Dodd–Frank Act stress test results, the FHFA proposes a going concern capital charge of 75 basis points times the unpaid principal balance of assets and guarantees.REF
Additionally, the proposal suggests two possible leverage ratio rules that would serve as alternative minimum capital requirements. The first option would require capital equal to 2.5 percent of total assets and off-balance-sheet guarantees, regardless of the risk characteristics of those assets and guarantees. The second approach would require capital equal to 1.5 percent of certain mortgage-backed securities held by third parties (and off-balance-sheet guarantees), as well as 4 percent of the companies’ remaining total assets (including off-balance-sheet assets).REF
According to the FHFA, the proposed framework is “designed to establish the necessary minimum capital for the Enterprises to continue operating after a stress event comparable to the recent financial crisis.”REF The FHFA estimates that, under this risk-based proposal, using 2017 financial data, the total capital required for Fannie Mae would be $115 billion, and the total for Freddie Mac would be $65.9 billion.REF Thus, the proposed framework would require a combined total of $180.9 billion in capital from the companies, slightly less than the total credit ($191 billion) that the companies have drawn from the U.S. Treasury since 2008.REF
As discussed above, this capital level—or any other level—could be targeted just as effectively with a single-risk weight. For instance, applying a 50 percent risk weight and an 8 percent capital requirement—the same as required of banks—to Fannie’s and Freddie’s mortgage assets and total off-balance-sheet exposures results in a combined capital requirement of approximately $212 billion.REF This figure is 11 percent more than required in the 2018 proposal, evidence that a fairly simple framework would require similar capital levels to a more complex system. The next section of this Backgrounder focuses on several issues that the FHFA should address to further strengthen the safety and soundness of Fannie and Freddie outside of government conservatorship.
Factors that the FHFA Should Consider
The FHFA is moving forward with plans to end the government conservatorship for Fannie Mae and Freddie Mac, so developing a strong capital framework for the companies is a laudable goal. While safety and soundness dictates that capital requirements should be rather high, basic economic concerns, such as the ability to earn a competitive rate of return on invested funds, dictate that firms would prefer relatively lower capital requirements.
To some extent, the FHFA will have to balance these competing factors, but the agency should err on the side of safety and soundness to better protect borrowers and taxpayers. Furthermore, the FHFA should ensure that the new capital rules mitigate the GSEs’ historical funding advantage, whereby Fannie and Freddie have been allowed to operate with higher leverage than their competitors. Historically, this type of advantage has contributed to the companies’ ability to grow larger than other financial institutions, thus increasing their systemic risk. The following ideas are offered to help regulators develop new capital requirements that foster a more competitive mortgage finance industry and more adequately protect borrowers and taxpayers.
Capital Is Not Equivalent to Cash. One often-overlooked issue with equity capital requirements is that they do not require the company to hold any type of asset in reserve to cover losses. Equity requirements merely compel the firm to fund its operations with a certain amount of equity rather than debt. If, for example, Fannie Mae raised $300 billion in equity to meet its capital requirement, it would then use those funds to buy mortgages and to pay employees to run its securitization business. The company would not, however, be compelled to hold any of the $300 billion in some type of cash reserve. For this reason, insurance companies of all kinds—even mortgage insurance companies—are typically required to hold reserves in the form of cash and liquid securities.REF Because Fannie and Freddie operate much like a mortgage insurance company, whereby their promise to make payments to investors ultimately depends on whether borrowers make their home mortgage payments, the FHFA should require cash reserves as part of any new capital framework. For comparison, as of 2018, the Mortgage Guaranty Insurance Corporation, one of the nation’s larger private mortgage insurance companies, held 64 percent of its five-year average revenue as loss reserves.REF
More broadly, most states require mono-line insurers (insurance companies that provide one specific type of insurance) to hold large contingency reserves, with as much as half of all insurance premiums held in reserve for 10 years to cover possible future losses.REF Similarly, large banks must adhere to reserve requirements and meet a minimum liquid asset requirement. The FHFA could better protect borrowers and taxpayers by requiring Fannie and Freddie to hold a fixed portion of their guarantee fees as a cash reserve against both expected and unexpected losses.REF
Insolvency Is Meaningless Without a Receivership Process. The amount of any company’s equity funding, recorded on the balance sheet, merely represents the amount of losses a firm can sustain before it becomes insolvent. When a company does reach insolvency, equity holders can lose their investment through bankruptcy or receivership, depending on the type of company. Prior to the Housing and Economic Recovery Act of 2008, no clear receivership requirement existed for Fannie and Freddie. While clear statutory guidelines now authorize (and in some circumstances require) the FHFA to shut down Fannie and Freddie if they become insolvent, the receivership process itself remains ambiguous.REF It remains critical, therefore, that the FHFA create a clear receivership process to shut down the companies if they again become insolvent. In the absence of such a process, any capital requirements will lack the necessary enforcement mechanism to protect taxpayers from another bailout of Fannie and Freddie.
An Overly Complex Capital Framework Is Unnecessary. Risk-based capital frameworks are based on subjectively determined risk weights that are subject to error and manipulation,REF and history demonstrates that a risk-based capital framework for Fannie and Freddie can fail miserably. In 1992, the Federal Housing Enterprises Financial Safety and Soundness Act specified a minimum leverage ratio and “a highly prescriptive approach to risk-based capital requirements for the Enterprises,”REF as well as a risk-based capital stress test. The stress test was designed to ensure that Fannie and Freddie could survive “a ten-year period with large credit losses and large movements in interest rates,”REF whereby the credit losses were triggered by an 11 percent drop in nationwide real estate prices.REF
Yet, in 2004, Fannie Mae was designated “significantly undercapitalized,”REF and the Office of Federal Housing Enterprise Oversight (OFHEO) required both Freddie and Fannie to maintain 30 percent more than the minimum capital requirement.REF By March 2008, the OFHEO lowered this surplus capital requirement to 20 percent above the minimum, provided that Fannie and Freddie would “raise significant capital and maintain overall capital levels well in excess of requirements.”REF In May 2008, after Fannie Mae raised an additional $7.4 billion in new capital, the OFHEO lowered the surplus requirement to 15 percent above the minimum.REF In September 2008, Fannie and Freddie were deemed insolvent and were placed in government conservatorship. Thus, despite an extensive risk-based capital framework, statutory minimum requirements, and the addition of nearly $10 billion in new capital, Fannie and Freddie still did not have adequate capital to withstand the 2008 housing downturn. Because it is impossible to know, ahead of time, what the “right” amount of capital will be to cover future losses, the best that regulators can do is set the capital level high enough to cover expected losses based on previous experiences. Thus, requiring capital sufficient to cover losses similar to those experienced in the 2008 downturn, as the FHFA’s 2018 proposal does, is a reasonable approach. To accomplish this goal, the new capital framework should be as straightforward and transparent as possible.
Risk Tends to Rise During Housing Booms. Fannie and Freddie have historically helped to fuel lending for home purchases during boom periods when housing sales are rapidly increasing and prices are rising, thus increasing the amount of relatively riskier loans in the financial system.REF To mitigate this problem, the FHFA could implement a capital buffer that requires Fannie and Freddie to add capital during boom periods. For instance, the firms’ capital ratio could be increased—by perhaps 1 or 2 percentage points—when home price growth breaches a fixed threshold, such as 50 percent above the long-term trend.REF Alternatively, the FHFA could modify the Federal Reserve’s countercyclical capital buffer framework to apply to the GSEs’ operations, perhaps by tying additional capital buffers to mortgage growth in various U.S. regions.REF
Fannie and Freddie Have an Unjustified Funding Advantage. Although Fannie and Freddie are somewhat unique compared to large U.S. banks, they have already demonstrated that their exposure to credit risk poses at least as much risk to the U.S. financial sector and to the economy. Thus, the FHFA’s new proposal should account for the fact that Fannie and Freddie have regularly been allowed to use higher leverage than private financial firms holding the same financial assets. For instance, just prior to the 2008 crisis, a bank holding Fannie Mae’s mortgage-backed securities would have had a capital charge of 1.6 percent (a risk weight of 0.2 times the required capital of 8 percent), whereas Fannie Mae could have held the same asset with a capital charge of only 0.45 percent. For any mortgage held on its balance sheet, Fannie Mae would have had a capital charge of (at most) 2.5 percent, whereas a bank would have had a 4 percent capital charge (a risk weight of 0.5 times the required capital of 8 percent).REF While large banks are typically leveraged at roughly a 12-to-1 ratio (for every dollar of equity, they have $12 in debt), Fannie and Freddie have been at least five times as highly leveraged (a ratio of at least 60 to 1),REF leading to higher returns for GSE shareholders and higher risk for taxpayers, borrowers, and the broader economy.
Separate from these specific concerns, a comparison of the operations of Fannie and Freddie with other large U.S. financial institutions suggests that regulators should view these firms similarly. For instance, the largest U.S. banks and the Federal Home Loan Banks (FHLBs) are an integral part of the U.S. home mortgage financing system. For decades, each of these institutions has had to meet rigorous capital requirements that were more stringent than those required of Fannie and Freddie.
A Comparison to “G-SIBs” and Federal Home Loan Banks
For decades, federal policy has allowed Fannie and Freddie to operate with far less equity—in other words, with higher leverage—than either the largest U.S. banks or the FHLB system. While there is no doubt that Fannie and Freddie do not operate exactly like banks or the FHLBs, each of these respective institutions is involved in funding trillions of dollars in home mortgages. Therefore, it is useful to compare the operations and the capital requirements for the largest U.S. banks and the FHLBs to those of Fannie and Freddie.
The FHLB system, created in the 1930s, is a government-sponsored enterprise that, like Fannie and Freddie, supports mortgage lending.REF Unlike Fannie and Freddie, the FHLB system is a set of member-owned cooperative banks that provide loans—known as advances—to their member institutions. The system consists of 11 regional FHLBs, with nearly 7,000 members, which include some of the largest financial firms in the United States, such as JPMorgan Chase, Wells Fargo, Citigroup, and Bank of America.REF
As of December 2018, the 11 FHLBs reported a combined total of $1.1 trillion in assets, with total advances of $728.8 billion (66 percent of its assets). Combined, the FHLBs also held $62.2 billion in mortgages.REF Among the individual FHLBs, the size and asset composition vary substantially. The Atlanta FHLB (total assets of $155 billion) is the largest in the system, and the Topeka FHLB (total assets of $48 billion) is the smallest. The ratio of advances to total assets varies from 50 percent (the Indianapolis FHLB) to 77 percent (the Pittsburgh FHLB).REF All of the FHLBs have similar capital ratios because they are each governed by the same capital requirements.REF In particular, each FHLB must maintain total capital equal to at least 4 percent of total assets, as well as a leverage ratio of at least 5 percent of total assets.REF As of 2018, the system’s average regulatory capital ratio was 5.4 percent.REF
Separately, all U.S. banks—including many that are members of the FHLB system—are governed by a set of formal capital requirements. In general, these requirements are implemented by one of three U.S. regulators, and they are based on principles developed by the international Basel Committee on Banking Supervision.REF The requirements differ for banks based on their size, with the smallest banks facing less complex capital rules and somewhat lower requirements. As of 2018, many U.S. banks with less than $10 billion in total assets can comply with an optional community bank leverage ratio framework that requires a tier 1 capital-to-asset ratio of 9 percent.REF Tier 1 capital consists mainly of common stock, so it is considered the most loss-absorbing form of equity capital.REF
The largest U.S. banks, referred to as global systemically important banks (G-SIBs), have to meet higher capital requirements based on the theory that their failure might pose a threat to the global financial system.REF As with the FHLBs, each of the eight G-SIBsREF has similar capital ratios because each is governed by the same capital requirements as the others.REF As a group, the G-SIBs have an average tier 1 capital ratio of 14.07 percent, an average tier 1 leverage ratio of 8.4 percent, and an average supplemental leverage ratio of 6.7 percent.REF Combined, the 8 G-SIBs have total assets of $11.5 trillion, and tier 1 capital of $939 billion.REF Collectively, the eight G-SIBs hold approximately $800 billion in residential mortgages.REF
For the past several years, the two largest U.S.-based G-SIBs were Bank of America and JPMorgan Chase, with total assets (as of December 31, 2018) of $2.4 trillion and $2.6 trillion, respectively.REF JPMorgan’s balance sheet reveals that its single largest asset is its loan portfolio (at $985 billion), and its second-largest asset is its securities trading book (at $414 billion). The bank’s loan portfolio consists of loans made to firms in all kinds of industries, but its single largest exposure is $143 billion in real estate loans.REF The balance sheet shows that JPMorgan funds its operations mostly with deposits ($1.47 trillion) and long-term debt ($282 billion). JPMorgan also has $257 billion in total equity available to absorb accounting losses. These equity and asset balance sheet figures result in an equity ratio of 10 percent, whereas the bank reports a (risk-weighted) total capital ratio of 15.5 percent, and a (risk-weighted) tier 1 capital ratio of 13.7 percent.REF
Bank of America’s balance sheet reveals similar lending and funding operations. The bank’s single largest asset is its loan portfolio of $937 billion, an assortment of loans that includes $209 billion in residential mortgages.REF The bank also has a trading book of $214 billion, and it separately holds $238 billion in debt securities, for a combined portfolio of $452 billion. Bank of America funds its business mainly with deposits ($1.4 trillion), while it reports long-term debt of $229 billion and total equity of $265 billion. These equity and asset balance sheet figures result in an equity ratio of 11 percent, and the bank reports a (risk-weighted) total capital ratio of 15.1 percent, as well as a (risk-weighted) tier 1 capital ratio of 13.2 percent.REF
Each of the two largest G-SIBs is smaller than Fannie Mae and slightly larger than Freddie Mac. As of December 31, 2018, Fannie and Freddie had total assets of $3.4 trillion and $2.1 trillion, respectively.REF For Fannie Mae, $3.25 trillion of its total assets were mortgage loans,REF while mortgage loans accounted for $1.89 trillion of Freddie Mac’s assets.REF Thus, a single asset category—residential mortgage loans—represents 95 percent of Fannie’s total assets and 91 percent of Freddie’s total assets. This level of concentration in a single financial asset is much higher than anything at either the FHLBs or the G-SIBs.
For instance, the FHLBs’ total advances to member banks represent about 67 percent of the FHLBs’ total assets, and JPMorgan’s and Bank of America’s total loans represent 38 percent and 40 percent of total assets, respectively. When the analysis is restricted to only residential mortgages, JPMorgan and Bank of America, the two largest G-SIBs, both have home loans that represent less than 10 percent of their total assets. Wells Fargo, the G-SIB that holds the largest dollar amount of residential mortgages, holds $321 billion in single family loans, representing 17 percent of their ($1.9 trillion) total assets.REF
With regard to funding their operations, nearly 100 percent of Fannie’s and Freddie’s assets are funded by debt.REF Fannie and Freddie issue bonds and notes, but they also issue guaranteed fixed-income securities (backed by mortgage loans), whereby they promise to repay investors a series of interest and principal payments. All of the companies’ debt, therefore, is ultimately tied to the performance of a single asset class (residential mortgages).REF While banks fund their operations mainly from a single source—short-term customer deposits represent 57 percent and 58 percent of JPMorgan’s and Bank of America’s total assets, respectively—the main risk associated with those funds is that large numbers of customers remove their deposits at once. Consequently, banks are required to hold 10 percent of their deposits as reserves.REF
Furthermore, large-scale bank runs, where masses of customers rush to remove their money from the bank, are exceedingly rare in the U.S. due largely to federal deposit insurance.REF In fact, banks generally saw an increase in both transaction and term deposits during the 2008 financial crisis.REF Recently, one Federal Reserve official even noted that “banks generally provide credit, with deposits providing stable funding.”REF Thus, it is far from clear that the short-term nature of banks’ main funding source makes their operations riskier than Fannie’s and Freddie’s mortgage business. Moreover, given their relatively high degree of asset diversity compared to Fannie’s and Freddie’s, at least one aspect of banks’ operations is clearly safer—banks hold a diversified asset portfolio (many types of loans) whereas Fannie and Freddie hold essentially one asset. Combined, Fannie and Freddie had total assets—all related to home mortgages—of $5.5 trillion in 2018, equivalent to about half of the total assets of all of the U.S. G-SIBs.REF
Given these financial conditions, there is no objective reason why regulators should allow Fannie and Freddie to be much more highly leveraged than the largest U.S. banks. In fact, given their sheer size and lack of financial diversification, to say nothing of their troubled financial history, it would be reasonable to require Fannie and Freddie to have higher equity capital requirements than the G-SIBs. Similarly, there is no clear reason why Fannie and Freddie should be allowed to operate with lower capital requirements than the FHLBs.
Recommendations for the FHFA
As part of an effort to usher Fannie and Freddie out of government conservatorship, the FHFA has announced that it will re-propose the 2018 capital framework that was released under Mel Watt, the previous FHFA Director. While it is unclear exactly which requirements the new proposal will include, current FHFA Director Calabria has announced that Fannie and Freddie should “maintain capital levels commensurate with their risk profiles.”REF Calabria has also drawn attention to the large disparity in leverage between the GSEs and the nation’s largest banks.REF Given their similarity in terms of risk, there is no objective reason why regulators should allow the GSEs to be five times as leveraged as these banks, as prior to the 2008 crisis.
To improve safety and soundness, as well as competitiveness in the mortgage financing market, the FHFA’s new capital framework for Fannie and Freddie should:
- Mitigate Fannie’s and Freddie’s funding advantage. At minimum, the FHFA should require Fannie and Freddie to take the same capital charge for mortgage-related assets as is required of the nation’s largest banks (in most cases, 4 percent for home mortgages and 1.6 percent for mortgage-backed securities). Applying the same risk-weighted capital scheme—the same 50 percent weight required of U.S. banks for residential mortgages, as well as the same 8 percent minimum capital ratio—would help to equalize the funding costs between banks and Fannie and Freddie.
- Increase Fannie’s and Freddie’s capital requirements. The FHFA should require Fannie and Freddie to meet the same 8 percent capital ratio required of large U.S. banks, and should also require additional capital buffers similar to the SLR and the CCB required of the G-SIBs. As an example, the FHFA could apply a 50 percent risk weight to Fannie’s and Freddie’s mortgage assets, and then require an 8 percent capital ratio, a 3 percent SLR, and a 2.5 percent CCB. Based on 2019 financial data, Fannie has approximately $3.4 trillion in mortgage assets (including $75.8 billion in off-balance-sheet exposures), and Freddie has approximately $2.3 trillion in mortgage assets (including $302 billion in off-balance-sheet exposures).REF This framework, therefore, would require Fannie and Freddie (combined) to have $387 billion in equity capital. This figure represents 13.5 percent of the firms’ risk-weighted assets, slightly below the average tier 1 capital ratio for the eight U.S. G-SIBs.
- Increase Fannie’s and Freddie’s cash reserves. Equity capital requirements necessitate that a company funds its operations with a certain amount of equity rather than debt. They do not, however, require the company to “hold” any type of asset in reserve to cover losses. For this reason, regulators typically require financial firms to hold reserves in the form of cash and highly liquid securities. The FHFA should require Fannie and Freddie to supplement their loss-absorbing capital by holding cash reserves similar to the nation’s largest mortgage insurers. The companies could, for example, be required to hold up to half of their guarantee fees as a reserve against possible future losses for 10 years.
- Implement a housing boom capital buffer. Fannie and Freddie have regularly helped fuel lending for home purchases during boom periods when housing sales and prices are rapidly increasing. Because credit standards tend to ease during housing booms, Fannie and Freddie have typically helped to increase the amount of relatively riskier loans in the financial system. To mitigate this problem, the FHFA should apply a capital buffer that requires Fannie and Freddie to raise more capital during boom periods. For example, the FHFA could require Fannie and Freddie to automatically meet a higher capital ratio—of perhaps 1 or 2 percentage points—when home price growth breaches a fixed threshold, such as 50 percent above the long-term trend.
Though it is technically not part of the capital requirement framework, the FHFA should also create a formal receivership process to wind down Fannie and Freddie if they again become insolvent. Creating this process will provide the enforcement mechanism needed to ensure that any capital requirements truly protect the housing finance system, borrowers, and taxpayers from another prolonged recession and bailout of Fannie and Freddie. Without such a process, regulators will face enormous pressure to keep the insolvent firms afloat regardless of their financial condition and the risk they pose.
The Federal Housing Finance Agency is expected to re-propose a new regulatory capital framework for Fannie Mae and Freddie Mac in 2020. Given the Trump Administration’s laudable goal of ending Fannie’s and Freddie’s government conservatorships, as well as the fact that the companies’ capital requirements remain suspended, a new proposal is clearly warranted. The details of the new proposal remain unclear, but FHFA Director Calabria has often drawn attention to the large disparity in capital ratios between Fannie and Freddie and the nation’s largest banks, as well as the companies’ incredibly high leverage ratios.
The FHFA should move Fannie’s and Freddie’s capital requirements closer to the type of capital rules imposed on large U.S. banks, with a basic capital ratio and additional capital buffers similar to the SLR and the CCB required of the G-SIBs. The FHFA should also require Fannie and Freddie to supplement their loss-absorbing equity capital with cash reserves and other capital buffers. Finally, in addition to the new capital framework, the FHFA should move quickly to develop a formal receivership process for winding down Fannie and Freddie if they again become insolvent. These changes will better protect borrowers and taxpayers from the kind of economic collapse that occurred in 2008.
