Business activity in the U.S. Midwest jumped to a six-month high in July, topping economists' forecasts and showing expansion in the region for the first time since April, a report showed on Friday.

The Chicago Business Barometer for July was 54.7, according to the MNI Chicago Report. Economists had forecast the index at 50.5 for July, after June's reading of 49.4. A reading above 50 indicates expansion in the sector.
