That was reinforced by government data showing spending on the construction of factories dropped in July and was down 6.7% from a year ago. A U.S. appeals court ruled last Friday that most of Trump's tariffs were illegal, adding more uncertainty for businesses. "I continue to see the broad economy generally and the manufacturing sector in particular as in a holding pattern until tariff-related uncertainty recedes," said Stephen Stanley, chief U.S. economist at Santander U.S. Capital Markets. The ISM said its manufacturing PMI edged up to 48.7 last month from 48.0 in July. A PMI reading below 50 indicates contraction in manufacturing, which accounts for 10.2% of the economy. Economists polled by Reuters had forecast the PMI would rise to 49.0. Seven industries, including textile mills, miscellaneous manufacturing and primary metals, reported growth last month. Among the 10 industries reporting contraction were makers of paper products, machinery, electrical equipment, appliances and components as well as computer and electronic products. Tariffs continued to dominate commentary from manufacturers. Some makers of transportation equipment said conditions were worse than the 2007-09 recession, adding "there is absolutely no activity" and "this is 100 percent attributable to current tariff policy and the uncertainty it has created." Some viewed the conditions as consistent with "stagflation."
