Nowadays, many credit card issuers such as banks are looking at their credit card offerings and coming to certain decisions in terms of their interest rates. Some are converting what are known as “fixed rate credit cards” to variable rate credit cards. Understanding the differences between these cards can be important, because interest rate is the single most visible cost factor when it comes to any credit card.

In general, since the credit markets took such a severe hit in late 2008, banks have been looking at their fixed rate credit cards and changing some of them to take advantage of the money that can be made by instituting variable interest rate formulas on the cards. For example, in the past, most credit card issuers offered cards with a stable interest rate that never changed.

Now, however, many banks are looking at the interest rates that have been fixed – and which usually are pegged to the prime interest rate in the United States – and figuring that they could make a bit more money by decoupling those interest rates from the prime, for one. It is, simply put, a way to generate a bit more income from cards that have featured low interest rates and which are probably capable of making a bank more money than normal.

That's why banks have been giving customers notice in accordance with the provisions of credit card laws that the former fixed rate card they're holding is going to feature variable interest rates that will adjust (at this point, usually upwards) based on the types and kinds of purchases a person is making on the card and what features and benefits the card has been offering.

This also isn't to say that fixed rate credit cards will be going away anytime soon, because most credit card issuers are still offering them to their best and most reliable customers, in terms of credit history and payment histories. The reason for this is because the competition to offer fixed rates is still out there among all of the banks and other issuers. At this point, it pays to keep good credit, especially in light of variable interest rates.

Finding a good set of fixed rate credit cards is still more a matter of using the Internet to research the cards – including terms and conditions and what the interest rate actually will be – than anything else. Also remember that banks are trying to push interest rates on all of their financial products – including credit cards – upwards, especially as their own costs for borrowing money have increased over the last 18 months.

No bank is operating as a charity, especially when it comes to credit cards, but those who understand how to use credit to their advantage can still make out in this economic climate, including finding fixed-rate cards that are attractive and offer a great many features and benefits. Just treat credit like the commodity that it is and all should be fine. Remember; those who treat credit cavalierly tend to be treated just as cavalierly themselves in the long run.
