The S&P 500 held lower on Wednesday afternoon after the Federal Reserve signaled comfort in moving to higher interest rate levels "fairly soon."

The S&P 500 was down 0.18% and the Nasdaq declined 0.13%. The Dow Jones Industrial Average climbed 0.06% after reaching an intraday record high of 20,771 earlier.

Many members of the Federal Open Market Committee said at the Jan. 31-Feb. 1 meeting that it would be appropriate fairly soon for the Fed to make a move higher, so long as the incoming labor market and inflation data was in line with or stronger than expected, the minutes from the meeting revealed.

Some members also expressed concern that language emphasizing a gradual pace may be misunderstood to mean only one rate hike this year. 

"A few participants noted that continuing to remove policy accommodation in a timely manner, potentially at an upcoming meeting, would allow the Committee greater flexibility in responding to subsequent changes in economic conditions," according to the meeting minutes. "Several judged that the risk of a sizable undershooting of the longer-run normal unemployment rate was high, particularly if economic growth was faster than currently expected."

The meeting minutes release confirmed a recent switch in rhetoric among Fed members in signaling that the U.S. economy is heating up and that it must act soon. The minutes also signaled that a move at the March meeting was still on the table.
