This monthly measure of consumer debt is volatile and subject to massive revisions. It is also released well after every other consumer spending indicator, including weekly chain store sales, auto sales, consumer confidence, retail sales, and personal consumption. For these reasons, the market almost never reacts to the consumer credit report.
Consumer credit is broken down into three categories: auto, revolving (ie, credit card), and other. Since we already have indications on total consumer spending well before this release, there is little to be gained from learning what portion of spending was financed through acquisition of debt. Periods of strong spending can be accompanied by relatively weak credit growth and vice versa, so this measure fails even as a coincident or lagging indicator.
