Federal Reserve Governor Christopher Waller has delivered one of the clearest hawkish signals yet from a sitting policymaker, explicitly backing a rate increase at the December FOMC meeting and warning that a larger-than-expected half-point move could be on the table if inflation data disappoints. The remarks, delivered during a speech in London, have sharpened market expectations and reignited debate over just how far the Fed is willing to go to defend its credibility.
The likelihood of a rate hike in the December meeting moved from ~80% to ~99% following the comments, with the chances of a hike in early 2027 also rising to more than 60%. Financial markets also responded swiftly to Waller’s comments, with the 2-year U.S. Treasury yield moving higher as traders shifted.
The U.S. dollar strengthened modestly against a basket of major currencies, reflecting the market’s interpretation that the Fed’s tightening cycle is far from over. Share markets, particularly rate-sensitive sectors such as technology and real estate investment trusts, have also moved negative, with the QQQ ETF down 0.42% in the pre-market having earlier traded positive.
What Did Governor Waller Say?
Waller’s remarks represent the most direct forward guidance from a Fed official since the central bank opted to hold rates steady at its October meeting. The governor made clear that the pause was not a pivot, framing it instead as a tactical delay rather than a signal that the tightening cycle had run its course.
He stated that he leans toward supporting a 25-basis-point increase even if October’s Consumer Price Index data shows some moderation, but drew a firm line in the sand around the possibility of a 50-basis-point move.

“In that case, I believe a 50 basis point hike in the policy rate should be considered at the December meeting,” Waller said. “Hiking only 25 basis points would put our credibility at risk, a risk I am not eager to take.”
Governor Waller argued that the Fed’s communications ahead of and during the October meeting had already led markets to price in additional tightening, and that failing to deliver on those expectations would cause rate expectations to collapse and inadvertently loosen financial conditions, the precise opposite of what the central bank is trying to achieve.
“When this communication is clear and credible, what really matters is that those hikes are eventually carried out — it is not necessary, for example, to raise rates at consecutive meetings,” Waller said. “If, however, the hikes are not carried out, markets will reduce expectations of rate hikes and rates will immediately fall, which would loosen monetary policy in an undesirable way.”
The broader macroeconomic backdrop supports the case for continued tightening, as inflation remains sticky, whilst the U.S. labour market has remained resilient, with low unemployment and steady payroll growth giving the Fed the policy room to prioritize price stability without triggering an immediate recessionary shock.
Interest Rate Outlook For 2027
Adding institutional weight to the hawkish narrative, Wall Street have also revised their rate forecasts upward in recent weeks, with Bank of America now projecting two sequential hikes; one in December and another in March, pushing the terminal rate to a range of 4.25%-4.50%, which it expects the Fed to hold through the end of the forecast horizon.
Goldman Sachs has similarly pushed its projected easing timeline further out, citing core PCE inflation hovering near 3% and continued labor market strength as justification for a prolonged restrictive policy stance.
The December FOMC meeting now carries heightened significance, with the October CPI print serving as the critical data point that will determine whether the Fed opts for a measured 25-basis-point step or an aggressive 50-basis-point move.
The Fed’s next move will ultimately be determined by data, but Waller’s speech leaves little ambiguity about the direction of travel. The question heading into December now doesn’t seem to be whether the Fed will hike, but by how much, and what comes next.
