If you have credit card debt, take the Federal Reserve's move to raise interest rates as a big, flashing warning sign.

Short-term rates are the most affected when the government nudges up the federal funds rate, which the Fed did last week, raising it a quarter point. It was the third move in 2018. One more hike is expected before year's end.

"That means your 15 percent interest rate on a credit card is now a 17 percent rate," said Greg McBride, chief economist for Bankrate.com. "If you haven't already, it's important to take steps to insulate yourself."

The message to get out of debt is a hard sell to the American households holding nearly a trillion dollars in credit card debt, according to Nerdwallet.com's 2017 survey.

Many pay only the monthly minimum payments, incurring interest charges that balloon their balances. It is a "treadmill to nowhere," McBride said.

On a card with a $10,000 balance, paying the minimum (interest plus 1 percent of the balance) will cost you $12,000 in interest and take 27 years to pay off at a 15 percent rate. Bump that up to a 17 percent interest rate, and you pay $13,600 in interest — plus, it would take an extra year to be out of debt.

Experts say you should push your credit card debt to a zero-percent balance transfer card. You can still get offers for as long as 21 months, with fees, according to Nick Clements, co-founder of the money advice site MagnifyMoney.com. Then pay down as much money as you can to reduce the debt in that time period.

It is also wise to explore the personal loan market, where rates aren't rising as fast because of competition, Clements said.

If you are in debt and own a home, now is not necessarily the best time to be tempted with a home-equity loan to pay off debt, said Tendayi Kapfidze, chief economist of housing site LendingTree.com.

The variable interest rates of a home-equity loan are also affected by the Fed raising interest rates, although not as highly correlated.

The biggest risk? Cashing out home equity to pay down debt, but then as soon as you are even, digging another financial hole and not having anything left to tap.

"You need a broader plan to control your spending," Kapfidze said.

For those looking to buy a house or refinance, the latest Fed move will have a slower impact. Other things influence mortgage rates along with the Fed funds rate, but those factors are heading in the same direction.

Kapfidze does not expect any large mortgage rate moves in the near term, but that, he said, is because there had already been a run-up in recent weeks.

Savings rates are the last to move because of Fed actions. Banks raise rates on what they are selling before they raise rates on what they are buying, Kapfidze said.

But if savers turn into shoppers, they will find some better deals in the coming months. Online banks are being particularly aggressive about rates for certificates of deposit, with new players like Goldman Sachs' Marcus, Clements said.

Investors should look at the yield on their fixed income investments, which might be around 3 percent, and compare it to a 12-month CD for 2.5 percent.

"If you think about it, low rates mean people take more risk. As rates are rising, people should be able to take less risk," Clements said.
