At yesterday's post-hike press conference, Federal Reserve Chair Warsh defined the rate increase with a three-word phrase, "dose of accommodation," and when pressed on where rates sit relative to the neutral level, his reply was equally telling: the concept is "academically useful" but carries "no operational relevance for the decisions we make today."

That single phrase and that one answer are forcing Wall Street to completely rethink this Fed's tightening trajectory and its overarching policy framework.

In Warsh's view, even with the target range raised to 3.75%-4%, policy remains stimulative—the hike merely removed one "dose" of that support. Meanwhile, the neutral rate, which has served as the Fed's primary anchor for judging policy tightness for over a decade, has been pushed aside from an operational standpoint.

CME FedWatch data shows the probability of another hike in October has jumped to roughly 58%, up from 42% just a week ago. Goldman Sachs and BofA have both added to their rate hike expectations, with BofA also forecasting a move in December. Futures markets are now pricing a terminal rate of 4.635% by the end of 2027, suggesting three to four more increases are in the cards.

A "Dose of Accommodation": Removing Just One Layer of Easing

Warsh repeated this formulation multiple times during the press conference, noting the decision to raise rates was based on an economy that appears to have "strengthened" and financial conditions that are becoming less restrictive.

Krishna Guha, head of economics and central bank strategy at Evercore ISI, called this the "most hawkish element" of the entire event in a client note. "This wasn't a slip of the tongue. He repeated it several times, clearly deliberate," Guha wrote. "This framework is a substantive departure from how the Fed has communicated in recent years, implying the number of hikes could be open-ended."

James Egelhof, chief US economist at BNP Paribas Securities, interprets it this way: in the Fed's lexicon, accommodation means stimulus. "This implies the current stance of monetary policy is significantly stimulative. With a stimulative starting point, strong cyclical momentum, and persistent inflation, it may take substantial rate hikes—perhaps more than our forecast of three—to stabilize the unemployment rate and prevent the economy from overheating next year."

Taking Warsh's framework at face value, Guha further noted, "rates may have to keep rising until the financial conditions facing the private sector are no longer 'accommodative'—however that is defined. That is a remarkably open-ended prospect."

Neutral Rate Shelved, Monetarism Takes the Stage

During the Q&A, CNBC's Steve Liesman asked directly how far current rates are from the neutral rate (r*).

Warsh responded that he studied the concept as an economics student—referring to the "Wicksellian real rate" named after Swedish economist Knut Wicksell—but called it "academically useful" and part of "the discussion that helps us think about policy," while insisting it has "no operational relevance for the decisions we make today."

This statement needs context. Since the Bernanke era, the neutral rate has been the central reference point for Fed policymaking—rates above it signal restraint, below it signal stimulus, and all policy debates revolved around this invisible benchmark. By relegating it to purely academic discussion, Warsh has effectively dismantled a positioning system that has guided the institution for over a decade.

Analysts suggest Warsh is steering the Fed's decision-making logic toward monetarism, calling it a "seismic shift." His predecessor Powell, who remains on the FOMC as a governor, had repeatedly and explicitly rejected core monetarist principles. Warsh, however, signaled this direction as early as August at Jackson Hole, highlighting a link between changes in the money supply and both economic activity and inflation.

Yesterday's press conference further confirmed this orientation. Warsh laid out several positions highly consistent with monetarist thinking: individual price movements in food or energy do not "cause" inflation, and the Fed must ensure these relative price changes don't generate second or third-round effects; single data points are "noisy," and what matters is the trend; the Fed deals with aggregates—the labor market, GDP, total spending, and headline inflation. Yet he also acknowledged that the lowest-income households, those living paycheck to paycheck without financial assets, stand to benefit most from price stability.

Money supply data has already offered clues. Warsh stated at least twice that he finds it difficult to describe current financial conditions as "tight." Analysts note that US broad money supply growth has been running in the 6%-8% range over the past six to nine months, clearly too high—to achieve the 2% inflation target, that pace needs to fall to around 6% or lower. Compared to the abstract and unobservable neutral rate, money supply growth offers a far more direct basis for policy judgment.

What Wall Street Is Pricing In

Jack Janasiewicz, chief portfolio strategist at Natixis Investment Managers, believes the "dose of accommodation" language "reinforces the hawkish tone, suggesting the committee no longer views policy as modestly restrictive." However, he says he does not "buy into this being the start of an aggressive new tightening cycle," instead leaning toward interpreting it as "walking back the insurance cuts the Fed implemented in autumn 2025."

If futures pricing holds, Warsh's Fed would at minimum reverse a significant portion of the easing approved under his predecessor Powell. But the current debate has moved beyond just the number of hikes—with the neutral rate exiting the operational toolkit and money supply taking center stage, the market must now adapt to an entirely new policy coordinate system. After three press conferences, Warsh has sketched out his framework, but where the tightening endpoint actually lies remains unanswered.
