Fed's Waller Floats Half-Point Rate Hike for December

Federal Reserve Gov. Chris Waller said on Tuesday he would back a half-point interest rate hike in December if October's core consumer price index comes in at 0.3% or stronger — the first concrete threshold a Fed official has attached to a bigger move.

If core inflation prints below that level, Waller said he would lean toward a quarter-point increase instead. His comments came at an event in London, where the yield on the 2-year U.S. Treasury rose 4 basis points as he spoke.

What did the market make of it?

Not much, at least in the pricing. Federal funds futures activity still shows no possibility of a half-point increase, according to LSEG data. In plain terms: traders are betting Waller's scenario does not materialize.

A 4-basis-point move on the 2-year yield is modest. Markets heard the governor, and largely shrugged.

Why is Waller worried?

"Let's just say it. September's inflation data were bad. There was no silver lining," said Waller. He pointed specifically to the breadth of price increases, not just their magnitude — a signal that inflation pressure has spread across categories rather than sitting in a few volatile corners.

In a subsequent question-and-answer session, he added that a 0.3% or stronger core reading would imply inflation is moving further from, not closer to, the Fed's 2% target. That is the logic behind his threshold: one hot month would be evidence the disinflation trend has stalled.

He also flagged a methodological caveat. If energy prices continue to run elevated, the Fed may have to shift its reliance on core price measures, which strip out food and energy. That admission cuts both ways — the Fed's preferred inflation gauge may be understating what consumers actually pay.

What about the dot plot and meeting schedule?

Waller addressed the message sent by the Fed's "dot plot," the quarterly projection of rate paths — which Chairman Kevin Warsh does not participate in. "The markets use that information to do pricing of rate hikes," he said. "I'm not changing anything I do or say." The remark acknowledges the tension between official guidance and his own public flexibility on a half-point move.

On the plan to reduce the number of vote-setting rate meetings, Waller conceded the case for a slower schedule on occasion. He cited one example: a Federal Open Market Committee meeting held just days after SVB and Credit Suisse failed, when the committee would have benefited from more time to assess the fallout.

The takeaway: the Fed is weighing fewer, better-spaced decisions against faster crisis response.

What surprised him most?

The strength of the U.S. consumer, which Waller called the most shocking development. Households have kept spending through successive shocks, including tariffs and war. He credited two forces: a tight labor market and asset-price strength, which together sustain households' willingness to spend.

That resilience is double-edged for policy. A consumer who keeps spending through tariffs and war gives the Fed less room to ease, and strengthens the case for Waller's half-point contingency.

The December decision now hinges on one number: if October's core CPI prints at 0.3% or higher, a 50-basis-point hike moves from theoretical to actively on the table — though futures markets still assign it no chance.
