The New York Federal Reserve's Empire State manufacturing index rose to 15.6 in July from 5.7 in June, compared with a smaller expected increase to a reading of 9.2 in a survey compiled by Bloomberg.
The Empire State index is the first manufacturing sector reading for July and suggests more widespread expansion.
The new orders, shipments, and employment readings all increased in the month, while the prices paid reading declined but still pointed to significant growth.
