Federal Reserve Rate Hike: Who Actually Pays When the Inflation Driver Is Rate-Insensitive

The Federal Open Market Committee is widely expected to lift the federal funds rate by 25 basis points (from the current range of 3.50% to 3.75%) making it the first increase since July 2023. Money markets have priced in an overwhelming probability of that move, and analysts are already framing this as the beginning of an extended tightening cycle.

Here's the part that's getting almost no coverage in manufacturing circles: two of the three primary drivers of current inflation are explicitly rate-insensitive. Iran-linked energy prices don't respond to what the Fed does. AI data center capital expenditure doesn't respond to what the Fed does. Barclays economists estimate the AI capex buildout alone could add up to four-tenths of a percentage point to headline inflation this year: through grid strain, semiconductor bottlenecks, and specialized labor competition.

The Fed's tool works by making rate-sensitive borrowers pay more. That is you. The manufacturer financing a press, a line upgrade, a new roof. Not the hyperscaler building 30 buildings on 1,200 acres in New Carlisle, Indiana, which is exactly what Amazon is doing.

PJM's most recent capacity auction cleared at $329.17 per megawatt-day, up from $28.92. That increase was driven by a combination of thermal generator retirements, tightened reliability requirements, and load growth from data centers. Hyperscaler demand isn't the only cause, but it's the one that's structurally accelerating, and New Carlisle is Indiana's local face of it.

Indiana's H.B. 1007 and S.B. 422 require large electricity users to pay for increased generation costs. The IURC's implementation guidance on who qualifies as a "large user" has received almost no public scrutiny, but that determination will directly set whether you or the data center next door absorbs the next round of grid upgrade charges. That rulemaking is getting finalized without most manufacturers in the room.
