The research was cited by President Obama in a report on the state of the economy, so you know it must be correct.
The survey of corporate executives found that many small and mid-sized firms survived the economic storm by tapping easy, low-cost lines of credit locked in ahead of the downturn, during an era of loose lending that also included sub-prime home mortgages. "These lines of credit were so liquid and so accessible that it made this recession far less acute than it would have been otherwise," he said.
In hindsight, the economy-sparing credit was likely ill advised, similar to the risky mortgages doled out to under-qualified homebuyers that contributed to an economic collapse now dubbed the Great Recession.
Extended amid a robust economy, the credit became potentially toxic for banks when the downturn hit, he said. Interest rates were not adequately risk-adjusted, and banks gave themselves no outlet to deny firms that needed money just to survive, rather than for business-building projects the credit is designed to finance.
"Some bankers made mistakes by authorizing these lines of credit and we're lucky they made those mistakes," Campello said.
"It saved those firms' skin during this recession, but probably won't be as easy to access next time. There will be stricter terms and, of course, higher interest rates."
Campello says lines of credit not only spared small and mid-sized firms from bankruptcy, but also let them emerge from the recession on more solid financial ground. As a result, those firms may now be poised hire and spend, providing a needed jolt as the economy rebounds.
"These companies have more cash, more profits and it may be nearing the point where they will start to hire," said Campello.
The nation's unemployment rate remained flat at 9.7 percent in February after peaking at 10.1 percent in October, but analysts say the job market is beginning to show signs of recovery.
The February jobless report offers promise, including stable manufacturing employment and a 30,000 increase in temporary workers who sometimes move up to full-time in the aftermath of recessions.
How quickly hiring escalates depends on when consumer confidence rebounds and whether the government pumps money into job-creating programs.
"A wild guess would be that employment will stay roughly where it is for six months, then pick up in the third quarter," Campello said. "But everything is still uncertain now. Obama calls this the recession of our lifetime and it is. It's a unique situation, even the recovery we may be looking at."
