How to Read Inquiries, Tightness, and Originations Together

Credit-card data can look contradictory when the measures are treated as if they count the same event. In the U.S. credit-card market, the CFPB's inquiry index, credit-tightness index, and origination measures answer different questions about access. Choosing the measure that matches the question—and labeling its base period, reference month, coverage, and finality—lets a reader use mixed movements as evidence to investigate rather than as a one-line verdict about tighter standards.

Choose the measure by the event it counts

Start with the question, not with the most vivid number on a dashboard. If the question is whether consumers are trying to obtain credit, the relevant measure is inquiry activity. If the question is whether those attempts are turning into additional credit, the relevant measure is credit tightness. If the question is how many new cards or how much new credit was actually originated, the relevant measure is origination activity. These measures are related, but moving from one to the next adds decisions by lenders and consumers.

The inquiry index is closest to the attempt. The CFPB defines it as the monthly number of consumers with credit-card inquiries, expressed as an index relative to January 2010. A credit inquiry is a hard credit pull associated with seeking credit. It can show that consumers are entering the application or screening process; it cannot show that a lender approved them or that an account was opened. A fall in the index can mean fewer consumers generated an inquiry, but it does not by itself distinguish weaker demand from fewer opportunities or stricter screening.

The index format is not a cosmetic choice. Lenders do not all pull credit reports from all three nationwide consumer reporting agencies, so a raw count assembled from one reporting source would not necessarily represent the whole market. Indexing makes relative comparisons possible within the series despite that coverage problem. If an index is 120, the measured level is 20 percent above its January 2010 reference level. It does not mean that 120 percent of consumers applied, or that the series rose by 120 percent. The base period is the denominator for interpretation.

The CFPB displays both a seasonally adjusted inquiry series and an unadjusted series. The unadjusted number describes the month as it occurred, including predictable calendar patterns. The adjusted series attempts to remove expected seasonal variation so that a reader can focus on a movement less likely to be explained only by the time of year. Neither version is automatically the right one. A reader studying the actual volume of applications in a particular month may need the unadjusted series; a reader comparing underlying changes across months may prefer the adjusted series. The choice should follow the question.

Credit tightness is not simply “inquiries, but worse.” It measures consumers who applied for a credit card and did not obtain additional credit, again as an index relative to January 2010. An increase means that fewer inquiries are transitioning into loans compared with the base period.
