Dow Rallies 557 Points as Rotation Out of Tech Offsets a Blistering PPI

Producer Price Index (PPI)

The Producer Price Index measures the average change in prices that domestic producers receive for their output. Where CPI tracks what consumers pay at the register, PPI tracks prices earlier in the supply chain: what a manufacturer, wholesaler or service provider charges. It is often read as a pipeline signal, because cost increases at the producer level can later be passed on to consumers, or absorbed as lower profit margins. Headline PPI includes food and energy, which are volatile, so analysts also watch measures that strip them out. The core measure Thursday's coverage highlighted excludes food, energy and trade services, because trade margins can swing sharply as retailers and wholesalers change their markups. Comparing the monthly change with the year-over-year change helps separate a one-off spike from a sustained trend. PPI does not map one-for-one to CPI. Some producer costs never reach consumers, and margins can compress or widen. Still, a large upside surprise raises the odds that inflation stays elevated, which matters for how central banks set interest rates.
