Although it hailed a pickup in economic activity since the sluggish first half of the year, the policy-making Federal Open Market Committee showed uncertainty about some persistent weak signs in the economy, and cut their 2016 growth forecast to 1.8 percent, down from 2.0 percent in June.
Yet the policymakers also displayed confidence the rebound would continue through the second half, and indicated that they foresee one rate hike before the end of the year.
"Although the unemployment rate is little changed in recent months, job gains have been solid."
However, they explained, they still needed more evidence that the economy was headed to full employment, as the jobless rate sites at 4.9 percent, and that inflation would pick up and move toward their 2.0 percent target.
"The Committee judges that the case for an increase in the federal funds rate has strengthened but decided, for the time being, to wait for further evidence of continued progress toward its objectives."
