Fed rate hike hinges on two key inflation reports in the next two days

The Federal Reserve’s next policy move is now squarely in the hands of the data calendar. Over the next 48 hours, markets will digest two critical releases: the Consumer Price Index (CPI) and the Producer Price Index (PPI). Both gauges have recently shown that price pressures are reaccelerating, reversing the disinflationary trend seen in late 2024. The core question for investors is not whether inflation is sticky, but rather what threshold would force the central bank to abandon its current hold and resume tightening.

The relevance here lies in the transmission mechanism. A hotter-than-expected CPI directly impacts real yields and rate-sensitive sectors, while the PPI serves as a leading indicator for corporate margins and final consumer costs. If the wholesale data shows sustained input cost increases, that suggests the CPI stickiness is not a statistical blip but a structural shift in supply chains. The Fed has repeatedly stated it needs "greater confidence" in the disinflation path; these two reports are the first major test of that conviction in 2025.

What to watch is the reaction function, not just the headline number. Specifically, look at the "supercore" services inflation and the persistence of goods deflation. If both reports show sequential monthly gains above 0.3%, the narrative shifts from "patience" to "restriction." However, the Fed may also look through a single month’s noise. The true signal will be whether the bond market reprices the terminal rate higher or if the data merely confirms the Fed’s existing wait-and-see stance.
