Truth in Lending: 55(b)(2) Variable rate exception.
1. Increases due to increase in index. Section 1026.55(b)(2) provides that an annual percentage rate that varies according to an index that is not under the card issuer’s control and is available to the general public may be increased due to an increase in the index. This section does not permit a card issuer to increase the rate by changing the method used to determine a rate that varies with an index (such as by increasing the margin), even if that change will not result in an immediate increase.
