Reuters: U.S. producer prices increased solidly in August, indicating that high inflation is likely to persist, with supply chains remaining tight as the COVID-19 pandemic drags on. The producer price index for final demand rose 0.7% last month, the Labor Department said on Friday. That followed two straight monthly increases of 1.0%. In the 12 months through August, the PPI accelerated 8.3%, the biggest year-on-year advance since November 2010, after surging 7.8% in July.
