The Producer Price Index (PPI) in the United States increased by 0.5% in September on a seasonally adjusted basis in comparison to August, according to a US Bureau of Labor Statistics report released on Thursday. On an unadjusted basis, producer prices rose by 8.6% for the 12 months that ended in September, the highest jump documented since the introduction of 12-month data in November 2010. Most of the increase in the final demand index was attributed to a 1.3% rise in prices for final demand goods. The index for final demand services was 0.2% higher. Unadjusted prices for final demand excluding foods, energy, and trade were 0.1% up in September compared to the previous month, while adding 5.9% year-on-year.
