But there is an even split.
As expected, the central bank left its benchmark interest rated unchanged in a range of 1.5 percent to 1.75 percent - but it added language acknowledging the recent rise in inflation, which lays the groundwork for another rate hike (this year's second) in June.
The statement said the economy has been growing at a moderate rate.
The FOMC's two-day meeting followed the release of data Monday that showed inflation measured by the central bank's preferred gauge had hit its 2 per cent target after being below that goal for nearly every month since April 2012. "I think it's basically a non-event".
That pushed French and German 10-year government bond yields to two-week lows.
The major averages ended the day just off their lows of the session.

The FOMC also noted the weakness in growth in the first quarter, removing a reference in the in March statement that the economic outlook had "strengthened in recent months".
However, there are other factors at play today that put pressure on Asian stock markets and currencies. Short-term rates are going to rise further and while longer-term rates have plateaued, they have done so at a rate that many thought they would not see until the end of this year. The press statement highlights that unemployment is now at pre-crisis levels and unemployment is continue to decline, with the number of people in work in the euro area now at the highest since the introduction of the euro, although the Commission also highlights that some slack remains at least on an overall level. "There will be more questions about "where do we go from here", he said. Just a few 2 years ago the yearly rate was almost zero.
