Things are pretty balanced, but there is a potential we have to accelerate the path" of rate increases if, for example, elected leaders were to find their way toward stimulative taxation and spending policies, or if wages were to heat up in a way that would drive inflation up more quickly than projected.
"I'm not completed wedded" to thinking two more rate rises will be enough for this year, Mr. Harker said.
On the hiring front, Mr. Harker said, "We're looking at a labor market more or less at full health, with very little slack." He said what is now a 4.4% jobless rate is likely to ebb to 4.2% by the end of 2018.
What is likely to be a 200,000 average monthly jobs gain this year should cool to a 100,000 average next year, he said, adding that slowing shouldn't be a problem. "To sustain a healthy economy, estimates of the ideal number range from about 70,000 to 100,000 a month to keep up with population growth," Mr. Harker said.
