Less than expected as the deceleration continues. I read this as reflecting a drop in consumer spending.

Though growth in headline consumer credit, at $12.4 billion, came in lower than expected, the component for revolving credit posted another sizable increase, at $4.1 billion vs $6.9 billion in May. This component, which is where credit card debt is tracked, has been on the rise this year raising the question whether financial firms are beginning to lend to less qualified borrowers.

Vehicle financing and student loans are tracked in non-revolving credit.
