“One of the reasons we pay a lot of attention to the PPI is because it sort of foreshadows prices that may be paid in the future by consumers,” said Anderson, a clinical assistant professor at the university’s Kelley School of Business in Indianapolis. “So, it certainly adds to the concern that the Consumer Price Index is going to potentially continue to be higher than desired over the coming months.”

The CPI is the most widely used inflation gauge, as it captures prices changes for a broad basket of goods and services commonly purchased by consumers. On Wednesday, the November CPI moved higher, landing in line with expectations; however, it also showed some stagnation in the Federal Reserve’s process of reining in inflation.

November’s PPI, however, came in hotter than economists had expected.

They anticipated producer-level prices would rise 0.2% on a monthly basis and 2.6% annually, marking an increase from October’s initial estimate of 2.4%, according to FactSet. The headline PPI was expected to increase partly due to unfavorable comparisons to this time last year, when inflation slowed sharply.
