Credit Market Conditions
Credit conditions are the price and the availability of borrowing for everyone who is not the U.S. government. When they tighten, the damage reaches hiring and spending months later.
History
What the credit subindex measures
The Federal Reserve Bank of Chicago builds its National Financial Conditions Index from 105 separate measures of money markets, debt and equity markets, and the traditional and shadow banking systems. The credit subindex takes the subset of those measures that describe credit: high-yield and corporate bond spreads, commercial paper spreads, bank lending standards from the Senior Loan Officer survey, consumer credit conditions and similar inputs.
Every version of the index is standardised so that zero equals the average over the sample that starts in 1971, with a standard deviation of one. That convention is what makes a reading comparable across five decades. A value of +1 does not mean one percent of anything — it means credit is one standard deviation tighter than the post-war norm, which is a genuinely unusual state.
Two episodes are worth keeping in mind because they show the index doing different jobs. In 2008 the credit subindex moved from below zero to its highest reading since the early 1990s within a few months, tracking a funding market that had simply stopped working. In 2020 the move was faster still but far shorter, because the Federal Reserve bought corporate credit directly for the first time and the index round-tripped inside a single quarter. Same indicator, two very different shapes.
Why credit turns before the economy does
Credit is the plumbing of the real economy. Firms borrow to fund inventories and payroll, households borrow to buy houses and cars, and both roll over existing debt as it matures. When lenders widen spreads or tighten standards, the change shows up in borrowing costs before it shows up in hiring, because the loan has to be priced before the spending can happen.
The record is unambiguous about the direction. The index reached its highest reading in May 1980, at the peak of the Volcker tightening, and its lowest in March 1973, when real rates were deeply negative and credit was as loose as it has ever been. Both extremes mattered: the first was followed by a severe recession, the second by the inflation that made the first necessary.
How to read the level against the percentile
The headline number tells you the state of credit today. The percentile tells you how unusual that state is against 55 years of history. The two disagree more often than people expect: a reading of −0.2 sounds unremarkable in isolation, and it is, but it still sits below the median of a series whose average is zero by construction.
What actually matters is persistence together with direction. One week of tighter credit is noise; six months of steadily rising readings is a regime. The summary line above the chart counts how many of the past 52 weeks closed tighter than average, which is a faster read on persistence than eyeballing the chart.
Why this page uses a Federal Reserve index, not a high-yield spread
The obvious way to track credit stress is the ICE BofA US High Yield Option-Adjusted Spread, the number quoted in every market commentary. We do not publish it, and the reason is licensing rather than difficulty. That series is the property of ICE Data Indices, its terms state that reproduction in any form is prohibited without prior written permission, and FRED's own notes describe the values as being for internal use only. Moody's seasoned Baa yield carries a similar restriction.
A site that republishes those series commercially is taking a legal risk it cannot insure, and it would also break the promise on our home page that every series here comes from a federal release. The Chicago Fed subindex is built by a Federal Reserve Bank, is free to use with attribution, and covers the same phenomenon through a broader set of inputs. That is the trade we make: slightly less quotable, considerably more defensible.
How we calculate it
We take the published NFCICREDIT series from FRED unmodified — no smoothing, no rescaling, no gap filling. The percentile is the share of weekly observations since January 1971 that sit below the current value. The change figure is the difference from the prior week's observation, in index points.
The index is published weekly as of Friday and usually appears in FRED the following Wednesday, so the newest observation is normally five to seven days old. Nothing on this page is intraday and nothing is revised after publication.
Distribution since 1971
Each row is the reading at that point in the historical distribution. A value in the 90th percentile is tighter than nine tenths of the record.

Questions
Does a positive reading mean credit conditions are bad?
Yes. The index is built so that zero equals the average since 1971. A positive value means borrowing is tighter than average — wider spreads, stricter lending standards, less availability. A negative value means conditions are looser than they have typically been.
How is this different from a high-yield spread?
A high-yield spread is one price: the extra yield on below-investment-grade bonds over Treasuries. The credit subindex blends that information with commercial paper spreads, bank lending standards, consumer credit conditions and other measures, so it captures availability as well as price.
How often is the data updated?
Weekly, as of Friday. The Federal Reserve Bank of Chicago publishes the index the following week, so the most recent observation shown here is usually about a week behind the calendar.
Why is the latest stretch of the chart locked?
The current reading and the full historical record back to 1971 are free. The most recent weeks — the part that tells you whether credit is tightening right now — are part of the member plan.
