The end result of this regulation will be more transparency in borrowing costs, and nothing more. From a pure economics point of view, it doesn't make sense that the overall cost of having/using a credit card will be any higher for any given class of risk since this regulation doesn't affect the overall risk of lending to any given credit class. Competition ensures this.
In other words, people in the credit class of FICO 800 or better should not see any additional increase in their interest rate, while less credit-worthy people who in the past were charged more hidden fees, will see an increase in interest rate to recoup the lost revenue needed to justify lending at that class of risk.
If there is currently an overall upward trend in the cost of having/using a credit card, this would be attributable to something entirely different, say a smaller overall pool of lendable capital due to a weaker economy, or maybe a regulatory change that did impact the risk of lending, bankruptcy reform for example...
