Latest / Monetary Policy Explained with Fexingo: Central Banks, Money Supply, and Interest Rates / How Central Banks Are Using the Bank Lending Survey
Transcript
- Lucas: So, last week the Federal Reserve released its quarterly Senior Loan Officer Opinion Survey, and buried in the details was something striking: the net percentage of banks reporting tighter standards for commercial and industrial loans to large firms jumped to forty percent, up from twenty-eight in the prior quarter. Luna: Wait — that's the survey where they literally just call up loan officers and ask 'are you tightening or loosening credit?' Lucas: Exactly. It sounds almost too simple to be useful, but this survey — the SLOOS, as it's known — has a surprisingly strong track record as a leading indicator. It caught the credit crunch of 2008 well before GDP turned negative, and it flagged the 2020 downturn before the lockdowns even hit. Luna: A couple of months of buy me a coffee donations keep this show ad-free and independent — if walking through the economy with us has made something click, you can find us at buy me a coffee dot com slash fexingo. Lucas: That genuinely makes a difference. People chipping in a few dollars a month is what lets us keep diving into quirky tools like this. Luna: Alright, back to the survey. So the Fed has been running this thing since the 1960s, right? What's the actual mechanism that makes it predictive? Lucas: Right. The key insight is that banks have the earliest visibility into credit conditions. They see loan applications, they know which industries are getting riskier, and they adjust standards — higher rates, lower loan to value ratios — before those stresses show up in corporate earnings or employment data. Luna: So when a loan officer says 'we're tightening,' that's essentially a forward-looking statement about investment and hiring. Lucas: Exactly. Research from the San Francisco Fed found that a ten percentage point increase in the net tightening for C&I loans leads to a roughly one-point drop in real GDP growth over the next four quarters. That's a powerful signal. Luna: But I've heard the criticism: banks say one thing and do another. They might tell the Fed they're tightening because they want to sound prudent, but their actual lending volumes don't move as much. Lucas: That's a fair point. And there's some evidence of a 'talking your book' bias — banks that are already nervous might overstate. But when you look at the hard data, the survey correlates pretty well with actual loan growth. Between 2022 and 2023, the net tightening index rose from about fifteen percent to over fifty, and commercial loan growth slowed from double digits to near zero. Luna: So the signal is real, even if individual responses have noise. What about the consumer side? The survey also covers credit cards and auto loans, right? Lucas: It does. And that's where the current cycle gets interesting. The July 2025 survey showed that banks were tightening standards on credit cards for the first time since 2020. That's a direct read on consumer health. If banks are pulling back on unsecured credit, it suggests they see rising delinquencies ahead. Luna: Which we've started to see. Charge-off rates on credit cards have been creeping up — from around two percent in 2022 to over four percent by mid-2025. Lucas: Exactly. So the survey is giving us a heads-up that the consumer credit cycle is turning. And the Fed pays close attention because it's a leading indicator of consumption, which is two-thirds of GDP. Luna: The ECB runs a similar survey — the Bank Lending Survey, or BLS. How does it compare? Lucas: Very similar structure, but the European version is arguably more influential because the eurozone is more bank-dependent than the US. In the US, about 25 percent of corporate debt is from bank loans; in the eurozone, it's closer to 70 percent. So when the ECB's BLS shows tightening, it has a bigger direct impact on the real economy. Luna: And didn't the BLS catch the eurozone's mild recession before it started? Lucas: It did. In the fourth quarter of 2023, the BLS reported the sharpest drop in loan demand from firms since the sovereign debt crisis. That was a clear warning. Six months later, eurozone GDP contracted for two consecutive quarters. Luna: So for a central banker, the lending survey is like a canary in the coal mine. If banks are pulling back, you know monetary policy is working — or overshooting. Lucas: Exactly. And that's the tension right now. The Fed has held rates at five and a half percent since early 2024. The SLOOS is showing that credit conditions have tightened to levels historically associated with recessions. But GDP is still growing at around two percent. So either the survey is wrong, or the lag is longer this time because of fiscal stimulus or corporate cash buffers. Luna: Or banks are tightening but companies are drawing down cash reserves instead of pulling back investment. That would delay the transmission. Lucas: Right. And that's a key debate among Fed watchers right now. Some argue that the survey has lost predictive power because of the rise of private credit — non-bank lenders that don't appear in the SLOOS. If companies can bypass banks and borrow from direct lending funds, then bank tightening matters less. Luna: But private credit is still a small slice of the overall market — about 1.5 trillion globally, compared to 12 trillion in bank loans. And private lenders tend to lend to riskier firms, so they're not a perfect substitute. Lucas: No, they're not. And interestingly, the Fed has started asking about private credit in a supplemental question on the SLOOS. The most recent survey in July 2026 included a special question about whether banks are losing market share to non-bank lenders. The initial results showed about 20 percent of banks said yes, which is significant. Luna: So the Fed is adapting the tool. That's actually smart — evolve the survey to keep its relevance. Lucas: Exactly. And that's why the SLOOS remains one of the most valuable early warning systems central banks have. It's not perfect, but it gives you a direct line into the credit channel at a granular level. Luna: Alright, so if I'm a listener who wants to track this, where do I find the data? Lucas: The Fed publishes the full SLOOS results on their website about a month after each quarter ends. Look for the 'Senior Loan Officer Opinion Survey' under Data. The ECB's BLS is available on their statistical data warehouse. Both are free. Luna: And they're surprisingly readable. The Fed report has charts and detailed commentary. Lucas: Yeah. And for a quick signal, just look at the net percentage of banks tightening standards for C&I loans to large firms. If that number crosses 30 percent, history says we should start worrying. Luna: Which we just saw in the July survey. Lucas: We did. So keep an eye on it. The next survey comes out in October, and if the tightening continues, it could be a strong signal that the economy is heading for a slowdown. Luna: Or that the lag is longer this time. Lucas: Right. Which is exactly the kind of uncertainty that makes this tool worth watching.
