These discrepancies are not inconsequential. Adjusting proxy shares to allow for even a small proportion of large loans
to be made to small businesses significantly alters our understanding of the evolution of small business lending since the
Great Recession. Using survey-generated metrics of banks’ actual lending activity shows that small business lending after
the recession likely recovered two to four years earlier than the proxy indicates. And given the wide variation in the degree to
which the proxy over- or understates bank-level small business lending, the ability of the proxy to correctly identify whether
one bank has a higher share of its commercial loan portfolio in lending to small businesses is limited.
The study is organized as follows: Section 2 discusses how the proxy measure came about and how SBLS data can be
used to assess its potential limitations. Section 3 contains our main analysis of the accuracy and precision of the proxy,
primarily for banks with $1billion to $10billion in assets. We exploit a disaggregation of banks’ C&I lending by firm gross
annual revenue (GAR) not collected by Call Reports but available in the survey data. Section 4 presents a separate analysis of
the overall accuracy of the proxy for measuring small business lending for only the smallest banks, those with assets of less
than $1billion. Section 5 concludes.
2 The Proxy and Diiculties in Measuring Small Business Lending
Understanding bank lending to small businesses is critical given the importance of small businesses to the U.S. real
economy and the importance of banks to small businesses. Unlike large businesses, small businesses generally do not have
access to capital markets and, therefore, typically rely on banks for most of their external financing.
14
Also, it is believed that
smaller banks are more suited to meet the credit needs of smaller businesses, often considered opaque given their lack of
audited financial statements.
15
Therefore, Congress mandated that small businesses’ dependence on banks be monitored,
which regulators implemented through the collection of proxy data via Call Reports.
16
To determine whether the proxy is a
useful measure of small business lending, we first discuss how the current proxy came about, introduce the SBLS survey
questions that can be used to investigate the proxy’s potential limitations, and evaluate whether survey data on firm size
reflect banks’ actual lending to small businesses.
2.1 A History of the Proxy for Small Business Lending
U.S. banks must file Call Reports at the end of each quarter. Section 122 of the FDIC Improvement Act of 1991 required
the banking regulatory agencies to annually collect data on bank lending to small businesses.
17
This requirement was
implemented in 1993 by the new Schedule RC-C, Part II of the Call Report.
18
Banks must provide “outstanding loan balances
with original amounts of $1million or less for commercial and industrial purposes, excluding loans secured by real estate and
loans for the purpose of financial agricultural production.” Banks provide the total number and total amount outstanding
for these loans, stratified into three buckets based on loan amount at the time of origination: less than $100,000, $100,000 to
14
For example, the Kauman Firm Survey, an annual longitudinal study that has followed almost 5,000 new firms since 2004, finds that outside debt, such
as credit cards, credit lines, and bank loans, was the most important source of financing for new firms, followed by owner equity (Robb and Robinson, 2010).
Combined, these two sources account for about 75percent of startup capital.

See Udell (2008) for a discussion of nonfinancial statement-based relationship lending technologies. Small banks are believed to be able to more cost
eectively process non-quantifiable so information, perhaps given their closer physical proximity to borrowers or flatter organizational structures, to make
viable loan decisions for borrowers that may have diiculty receiving financing elsewhere. See, for example Berger et al. (2005) and Berger and Udell (2002).

See 84 Fed. Reg. 55688-9 (October 17, 2019) for more background on how the Federal Reserve Board uses these data to monitor credit conditions and
assess real economic activity.

Banks must collect data on small farm lending as well; see 12 U.S.C. § 1817.
18
See 57 Fed. Reg. 54633 (November 19, 1992). The schedule was to be completed as of June 30 of each year. Aer the Great Recession, to collect better trend
data, the agencies increased the reporting frequency to quarterly beginning with the first quarter 2010 Call Report; see 74 Fed. Reg. 68322 (December 23,
2009). In 2017, the agencies again adjusted the frequency of the collection for institutions with less than $5billion in assets, from quarterly to semiannually,
to reduce reporting burden. Banks with assets of less than $5billion submit the “Consolidated Reports of Condition and Income for a Bank with Domestic
Oices Only and Total Assets Less than $5 Billion,” or FFIEC 051. The two other versions of the Call Reports are the “Consolidated Reports of Condition and
Income for a Bank with Domestic and Foreign Oices,” or FFIEC 031, and the “Consolidated Reports of Condition and Income for a Bank with Domestic Oices
Only,” or FFIEC 041. See 82 Fed. Reg. 2444 (January 9, 2017).
