Securitization and Small Business
Small businesses have relied considerably on securitized markets for credit. The recent financial crisis led to a virtual cessation of securitization of some of the loans used by small businesses, such as commercial real estate mortgages, vehicle, and credit card loans. In addition, values of commercial and residential real estate, which small businesses often use as collateral for loans, dropped dramatically. As a consequence, small businesses may have experienced tighter credit conditions than larger businesses, which rely relatively less on those categories of loans and collateral.
Small businesses have long had less access to credit than large businesses. Large enterprises have traditionally been able to borrow both from banks and from the broader credit markets by issuing bonds, commercial paper, and other debt securities. By contrast, small businesses generally could not access these broader credit markets and were generally regarded as “bank dependent.” Small business lending was long the province of smaller community banks and finance companies. Small businesses tend to have less collateral, shorter track records, and less verifiable financial statements than large businesses. These financial market frictions may have impinged on smaller businesses’ borrowing, even from community banks.
Perhaps because of such frictions, small businesses often turn to sources other than banks and finance companies for credit. Federal Reserve surveys indicate that traditional bank loans substantially fund small businesses. But the surveys also show that small businesses rely heavily on other sources of funds, including personal and business credit cards; residential mortgages and home equity loans; and family and friends.
Small business funding has also come to be importantly, if not obviously, connected to the broader credit markets. These markets were severely disrupted by the recent financial crisis. As a consequence, supplies of credit to small businesses diminished. Credit to small businesses may have been reduced more than credit to larger businesses.
The boom in securitization
Over the past three decades, enormous volumes of loans have been securitized. Securitization is the process of amassing a large number of a given category of loans into a pool and then issuing groups of securities that can differ by maturity or credit quality. Payments to securities holders are funded from the payments that borrowers make on loans in the pool. A wide variety of consumer loans are regularly securitized, including first and second residential mortgages, car and boat loans, credit card balances, and student loans. These asset-backed securities (ABS) can be tailored to match investor needs. This encourages investors to make more credit available to borrowers through ABS purchases. In contrast to the widespread securitization of consumer credit, securitized pools consisting solely of small business loans (SBLs) are relatively rare, perhaps because it is difficult to deal with the great heterogeneity in business loans and in the collateral that might be repossessed in the event that those loans default.
Despite the rarity of SBL pools, the growth of securitized markets has significantly increased access to credit for small businesses in several ways. First is through the securitization of consumer loans, which owners often use to fund small businesses. Another way is commercial real estate mortgages. Over the past two decades, the volume of commercial real estate mortgages pooled to create commercial mortgage-backed securities (CMBS) grew enormously. Although CMBS have been partly backed with pools that include commercial real estate mortgages owed by large businesses, these pools also came to include considerable volumes of mortgages owed by small businesses. To provide investors with more securities backed by business loans, banks may elect to originate more loans by offering businesses better loan terms. Other smaller, indirect sources of funding for small businesses include investor purchases of securities backed by trade credit and securities issued by finance companies. ABS, CMBS, and residential mortgage-backed securities (RMBS) are sold in global credit markets to pension funds, bond mutual funds, hedge funds, insurance companies, individual investors, and banks. Thus, securitization has provided small businesses with expanded access to funding sources beyond banks.
Banks originate a large share of the consumer, small business, and commercial real estate loans that are securitized. As a result, small businesses seem especially reliant on banks for credit. Banks retain some of the loans that go to small businesses, including both those formally categorized as small business loans, and the consumer and residential loans that small businesses also use. But, to varying extents, banks sell those loans, often into securitization pools. After being sold, the loans typically no longer appear on the balance sheets of the originating lenders and the ultimate funding of these loans essentially is provided by the broader credit markets. Thus, because banks originate many securitized loans, small businesses may appear to be more bank dependent than they really are.
The volume of bonds and commercial paper directly issued by small businesses would suggest that their connection to the broader credit market is minimal. However, the volume of small business loans pooled and securitized into CMBS, including multifamily real estate loans plus borrowing from finance companies, indicates that small businesses get considerable indirect funding from the broader credit markets.
Estimated business loans from broad credit markets

We do not know when a particular credit card or mortgage loan is used to fund a small business or what fractions of those loans are sold by the originators. However, we can make some overall estimates. Figure 1 shows my preliminary estimates from 1980 through the first quarter of 2011 of the aggregate percentages of large and small business debt obtained from the broader credit markets. Such credit may be obtained directly, such as by issuing commercial paper or corporate bonds, or indirectly, such as by issuing commercial mortgages that are securitized. To obtain these estimates, I assumed that noncorporate businesses had the same proportion of multifamily and commercial mortgages securitized as corporate businesses did. These estimates also included data for credit from finance companies. Commercial mortgage-backed securities, including multifamily mortgages, accounted for over 90% of my preliminary estimate of total credit provided by the broader credit market to small businesses.
Figure 1 shows that the percentages of large business debt associated with the broader credit markets have exceeded 50% at least since 1980 and since then have risen fairly steadily to 76%. By contrast, small businesses historically were much less connected to the broader credit markets. In the middle of the 1980s, less than 5% of their debt was owed on loans that tended to be securitized. However, by the mid-2000s, that share had grown to over 20%.
Small businesses rely more than large businesses on residential and commercial buildings as mortgage collateral. Noncorporate businesses owed 93% of the multifamily mortgage balances and 68% of the remaining commercial real estate mortgage balances outstanding in 2011. As a result, as the market for CMBS, including multifamily real estate loans, expanded greatly in recent decades, so too did the connections—and the vulnerability—of small businesses to the broader credit markets. During the recent financial crisis and recession, residential and commercial real estate prices fell dramatically. Thus, the value of small business collateral fell considerably in the recent recession, constraining the amounts small businesses could borrow.
Large businesses have long been able to borrow by issuing corporate bonds, commercial paper, or leases, or by taking out syndicated loans. When credit markets nearly shut down during the financial crisis, large businesses faced extraordinarily tight credit conditions. So did small businesses. Because small businesses relied so heavily on securitized consumer, residential real estate, and commercial real estate loans for funding, they were vulnerable to the breakdowns of these markets.
Medium-sized businesses may have initially been less affected. They were typically too large to rely heavily on the types of securitized credit used by small borrowers, such as personal or business credit cards, residential loans, or personal loans. And they were too small to access broader credit markets by issuing bonds or commercial paper. Typically, they relied less on the broader credit markets, either directly or indirectly, and more on banks. Often, they had close banking relationships because of previous borrowing and other activities. Other research suggests that such relationship lending can partially insulate firms in a financial crisis (see Monferra and Sampagnaro, 2011).
Securitization and relationship lending may help answer an apparent puzzle. Why did banks and small businesses report that credit was so much tighter, while bank data showed relatively small declines in outstanding SBLs during the financial crisis? Fed surveys registered a record tightening of bank loan underwriting standards during the crisis and the National Federation of Independent Business recorded its lowest readings ever for loan availability. At the same time, bank small business loan portfolios shrank less than 2% in the year ending June 2009.
Part of the reason for this modest decline in business loans is that many businesses were able to draw upon existing lines of credit. However, another potential explanation may lie in the drastic decline in securitization. Although bank holdings of small business loans may have declined only modestly, the flow of new SBL securitizations declined sharply. Thus, the virtually complete cessation of securitization during the crisis importantly reduced credit supplied to small businesses, even though banks initially continued to hold almost the same volume of small business loans.
Credit in crisis

Since the onset of the crisis, the credit environment for smaller nonfinancial firms has been much different than for larger nonfinancial firms, due partly to the decline in the values of commercial real estate and the meager rebound in CMBS securitization. Figure 2 shows recent issuance of corporate bonds, CMBS, and non-real-estate ABS. New issues of corporate bonds, an important credit source for large businesses, dropped sharply in 2007 and 2008 before recovering somewhat. While corporate bond issuance has yet to consistently surpass its 2006–07 peak, its average during 2010–11 was higher than it was before the pre-crisis credit boom.
The figure also shows that ABS issuance collapsed during the crisis. Issuance rebounded after 2008 to about half its 2007 level. The ABS 2009 recovery was probably due in part to the Fed’s Term Asset-Backed Securities Loan Facility program, which provided loans to ABS investors. The recovery may also have reflected the fact that these securities were backed by assets other than real estate, such as vehicles.
Figure 2 also shows that, during the crisis, CMBS issuance—the chief avenue through which small businesses connected to the broader credit markets—halted almost completely and has remained virtually nonexistent since. Declines in residential and commercial real estate prices and uncertainty about future prices may continue to reduce investor willingness to fund loans collateralized by real estate. Thus, small businesses may find that their real estate collateral won’t support the volumes of credit they used to, at least in the immediate future.
Although credit analysts have long advocated securitization of small business loans, pools consisting solely of SBLs have been rare. Despite this, small businesses have found ways to access the broader credit markets through securitized real estate, credit card, vehicle, and other loans.
Diversification often reduces the vulnerability of small businesses to disruption of any single source of credit, whether from banks or segments of the broader credit markets. While diversification of credit sources has some benefits, it cannot completely shield borrowers from a widespread financial crisis. In the recent crisis, funding from banks and the broader credit markets were both disrupted. To the extent that smaller businesses had become more connected to the broader credit markets, they may have faced tighter credit conditions than their medium-sized counterparts. Moreover, to the extent that corporate bond markets returned to normal after the crisis, the credit disruptions faced by many large businesses ended sooner than the disruptions faced by small businesses. Recognition of the particular vulnerabilities of small business to financial crises is vital if we are to develop effective credit maintenance policies, such as public loan guarantees.
