The U.S. Producer Price Index (PPI) for September showed a 6.3% annual increase, marking the highest level of wholesale inflation in over four years. The monthly increase was 1.3%, exceeding economist expectations.
This surge was primarily driven by energy prices, which accounted for 80% of the leap in goods prices. These costs were influenced by the U.S. war with Iran and Middle East conflict, specifically following U.S. and Israeli attacks on Iran in February.
