Strong domestic demand in August boosted Italian industrial orders, which jumped 10.2% on the month, national statistics institute Istat says. Domestic orders rose 12.3%, while foreign orders were up 7.1% from July. Orders are a proxy for future industrial output, a key metric for Italy, which has Europe's second-largest manufacturing sector after Germany. Industrial sales rose 4.1% on the month and 10.0% on the year, Istat says.
