WASHINGTON — The Federal Reserve today raised a key interest rate after seven years of record lows. But it’s signaling that further rate hikes will likely be made slowly as the economy strengthens further and muted inflation rises.

The Fed’s move to lift its key rate by a quarter-point to a range of 0.25 percent to 0.5 percent ends an extraordinary seven-year period of near-zero rates that began at the depths of the 2008 financial crisis.

Consumers and businesses could now face modestly higher rates on some loans.

Rates on mortgages and car loans aren’t expected to rise much soon. The Fed’s benchmark rate doesn’t directly affect them.

Long-term mortgages, for example, tend to track 10-year U.S. Treasury yields, which will likely stay low as long as inflation does and investors keep buying Treasurys.

But rates on some other loans, like credit cards and home equity credit lines, will likely rise, though probably only slightly as long as the Fed’s rate hikes remain modest.

The Fed’s action reflects its belief that the economy has finally regained enough strength 6½ years after the Great Recession ended to withstand higher borrowing rates. But the statement announcing the rate hike said the committee expects “only gradual increases” in rates going forward.
