There were no surprises at today’s Federal Open Market Committee (FOMC) meeting as the Fed lowered its overnight lending rate by 25 basis points to 2 percent.

Homeowners with adjustable-rate mortgages should be pleased, as the lower rates will offer some relief on their payments. Consumers with long-term loans, such as 30-year fixed rate mortgages, are largely unaffected by the Fed’s rate drop.

Variable rates usually move in the same direction as the federal funds rate. The federal funds rate, however, doesn’t affect long-term rates, which include financial products like 30-year fixed-rate mortgages; those tend to move with long-term Treasury yields.

“As a consumer, a quarter-point rate drop shouldn’t make you do anything that you wouldn’t have normally done this morning when you woke up. The rate drop is money — but it’s not life-changing money,” says David Druey, Southeast Florida regional president for Centennial Bank. “If you’re tight looking at a house that’s $300,000, today’s announcement won’t change that.”

How Fed rate affects short-term loans

Most variable and short-term rates are linked to two benchmark rates: the prime or the London interbank offered rate (Libor) plus a margin, which is a number of percentage points. These rates usually march in step with the federal funds rate, so a drop in rates could mean an extra jingle in some borrowers’ pockets.

One thing to note is that Libor as the key rate in mortgage contracts is on its way out, which is important for consumers to keep an eye on. Loans might get more expensive once Libor is replaced, says Greg McBride, CFA, Bankrate chief financial analyst.

“The future for many adjustable-rate mortgages is further clouded by the coming demise of Libor as a loan index. There is an open question as to whether the replacement index and margin will mean a higher rate for borrowers than the current Libor plus margin,” says McBride.

Addled with credibility issues, largely due to manipulating rates in order to drive profit, Libor will likely be replaced by risk-free rates or RFRs. The major flaw in Libor is that it depends on empirical data, which means banks report rates without being required to provide numbers to back up their claims. This process led to some Libor banks underreporting their interest rates for profit, which meant higher loan prices for some borrowers.

Unlike Libor, RFRs would promote transparency by calculating rates based on real transactions in the market.

What ARM borrowers should know

Variable-rate loans, such as 3/1 and 5/1 ARMs, as well as home equity lines of credit, or HELOCs, get more or less expensive as the Fed boosts or lowers rates. This can be a boon for borrowers or a drain on their wallets, which makes variable-rate loans a sometimes risky proposition.

Products like 5/1 ARMs give consumers the first five years with a fixed rate; after the fixed-rate period ends, there are annual rate adjustments for the remainder of the loan. So, if your rate drops during the adjustment period — such as what happened today, the cost of your ARM drops, too.

Many HELOCs are also variable rate loans, which means a win for borrowers in a falling rate environment.

The problem is that rates don’t always drop. So, it’s important for borrowers to analyze all scenarios: how much they’ll spend as well as how much they’ll save if rates rise and fall. It’s important to ask yourself: can I afford my mortgage payments if rates spike? Although your initial out-of-pocket payment will likely be lower with an ARM, that low cost might not last if rates rise.

“My brother and sister-in-law have a 5/5 ARM with a great rate and a low down payment. But, if rates go up in 5 years, their payment might go up by a couple hundred bucks a month. That’s a big increase,” says Sean Murphy, associate vice president of equity lending at Navy Federal Credit Union.

(A 5/5 ARM is a 30-year adjustable-rate mortgage with a principal and interest payment that stays the same for the first 60 months, and after that, the interest rate could rise or fall every five years.)

Often borrowers choose ARMs to get the lowest initial rate possible, regardless of the variable-rate risk. This can be a cost-saving strategy if the borrower is certain they’re going to sell before the fixed-rate period ends or can refinance into another mortgage.

For borrowers who plan on staying put or might not be able to refinance later (due to credit or employment issues, for example), that upfront cost-savings likely isn’t a worthwhile gamble.

“There is only about one-quarter percentage point difference between the rate on a 7/1 ARM and a 30-year fixed. For a quarter percentage point, are you going to subject yourself to potentially higher rates seven years from now? You’ve gotta be awfully certain you’ll be out of that house within seven years to make that risk pay off,” McBride says.

Consumers may want to keep an eye on these indicators

The Fed’s decisions on rate movement are often influenced by several economic factors, which consumers can easily track. Employment, inflation and consumer price index are essential data the Fed considers when deciding what to do with rates.

One thing consumers want to look at is the employment report, which is published monthly by the Bureau of Labor Statistics, or BLS.

The target inflation rate is another yardstick for rate changes. Currently, inflation is dipping just below the Fed’s target 2 percent rate, which — in concert with other economic trends — could nudge the Fed toward future rate cuts.

For borrowers who want to refinance into a fixed-rate mortgage, now is a good time to do it, says Nothaft. As long-term rates hover around the low 4 percent mark, many borrowers are in a good position to save money. But these low rates might not last, Nothaft warns.

“There’s a lot of uncertainty in the marketplace. Along with the global economy and tariffs, the oil supply in the Mideast is also something to track. If something unexpected happens that disrupts oil supplies you could see a big jump — up or down — in long-term interest rates. Tomorrow something could happen and rates could jump a percentage point. Refinance sooner than later. You’ll get the benefits of lower interest rates the sooner you close,” Nothaft says.
