Many Federal Reserve policymakers expect that interest rates will have to be raised in the "near term," according to the minutes of the Fed's last policy meeting.
The minutes from the October 31-November 1 meeting, at which the Fed kept rates unchanged, also showed policymakers generally agreed the economy was poised for strong growth.
Several Fed officials also saw improved chances that the US Congress would pass significant tax cuts that would boost business investment.
While some policymakers said they still needed to see more data before deciding the timing of a rate hike, many of the officials said the jobless rate appeared to be too low for inflation to remain at its current weak level.
"Participants expected solid growth in consumer spending in the near term, supported by ongoing strength in the labor market," the Fed said in the minutes.
"Many participants thought that another increase in the target range for the federal funds rate was likely to be warranted in the near term," it added.
The Fed has increased rates four times in a tightening cycle that began in late 2015. The Fed currently predicts one more rate rise this year and three more hikes in 2018.
The meeting marked one of the last policy reviews to be attended by Fed Chair Janet Yellen.
She announced earlier this week that she would resign from her seat on the Fed's Board of Governors once Jerome Powell is confirmed and sworn in to replace her.
President Donald Trump nominated Powell, who is expected to be in place when Yellen's four-year term as Fed chief ends in February.
In the minutes, policymakers engaged in what has become a regular debate over why inflation has remained below the Fed's 2% target for several years.
Most agreed that tightness in the laboir market would likely fuel higher inflation in the medium term.
Some of the members who vote on policy, however, expressed concern over the inflation outlook, according to the minutes.
These policymakers emphasised they would be looking at upcoming economic data before deciding the timing of future rate rises.
A couple of policymakers were concerned enough about persistently weak price gains that they suggested the Fed consider a new framework in which it committed to allowing higher inflation to make up for periods of low price rises.
Since the last policy meeting, Yellen has stuck by her prediction that inflation will soon rebound toward the Fed's target, although this week said she is "very uncertain" about this and is open to the possibility that prices could remain low for years to come.
