A stunning acceleration in second quarter growth and a jump in inflation triggered a new round of speculation that the Fed will have to speed up plans to hike rates.

The faster pace of growth makes it more likely the economy will grow at a better clip in the second half, but strategists do not expect the Fed to change its timeline unless there is a consistent jump in activity. The number is not expected to have any impact on the Fed statement scheduled for 2 p.m. EDT Wednesday.
