The Producer Price Index, which measures inflation upstream from consumers, registered another month of increased prices in September in what is more bad news for the Biden administration's attempt to get any modicum of positive economic news before November's midterms. Headline PPI inflation showed prices increasing 0.4 percent in September, double the 0.2 percent economists predicted for a 12-month increase of 8.5 percent, a rate that also surpassed Wall Street estimates. What's more, the month-over-month number shows that cost increases are accelerating for producers, with final demand services advancing 0.4 percent in September after increasing 0.3 percent in August.
