Should Regulators Stop Pushing Banks to Diversify Their Lending?

Banks become more-efficient lenders as they gain exposure to borrowers in a new industry.
But skipping audited statements didn’t lead to greater loan losses. The researchers conclude that specialized banks “are trading off alternative information sources rather than recklessly forgoing audit requests.”
Larger banks tend to collect more documented (or so-called hard) information while smaller banks rely more on conversations and personal relationships. But Berger, Minnis, and Sutherland say their findings are unrelated to the size of the bank or the borrower.
“An explanation consistent with our evidence is that concentration fosters lending expertise,” they write. “A bank with more exposure to an industry has better information about it, and, thus, less need to obtain high quality (and costly) financial performance information from borrowers in the industry.” Conversely, a bank with less concentration and experience needs to see audited statements. However, the researchers caution against extrapolating their findings too far. “Our findings do not support extreme concentration,” notes Minnis. “While on the margin, concentration fosters expertise, at some point the increasing risk of concentration surpasses the benefits of expertise.”
It generally takes a bank four-and-a-half years to accumulate enough information to make it knowledgeable, the researchers find. When a bank first lends to borrowers in a specific sector, the audit rate is over 6 percent higher than for the bank’s other loans, but it declines as the bank gains expertise in the area.
