NextFin News - U.S. Treasury prices rose and yields fell on Thursday after Federal Reserve Governor Christopher Waller said he is inclined to support holding the federal funds rate at its current 3.50 percent to 3.75 percent setting at the September 15-16 policy meeting, provided incoming inflation data continue to show progress. The two-year Treasury yield, the maturity most sensitive to the Fed's rate path, dropped as much as seven basis points to 4.30 percent, and the dollar weakened against all of its Group-of-10 peers.
The remarks mark a deliberate step back from the hawkish repricing that followed Fed Chair Kevin Warsh's speech at the Jackson Hole symposium a week earlier, when investors sharply increased their bets on a quarter-point rate increase. Prediction markets now price roughly a two-thirds probability that the target range holds at 3.50 percent to 3.75 percent, about a one-third chance of a hike to 3.75 percent to 4.00 percent, and virtually no chance of a cut. The only major inflation reports before the meeting are the consumer and producer price indexes, due September 11.
What Waller Actually Said, and Why the Market Heard "Hold"
The market reaction was large relative to the measured tone of the speech because of what Waller's words did to the distribution of outcomes around the September meeting. Speaking at a news interview in Washington, Waller laid out an explicitly conditional stance:
"While inflation remains meaningfully above the Federal Open Market Committee's 2 percent goal, recent data suggest we are finally seeing some signs of disinflation. If this continues in the data due over the next two weeks, I would be inclined to support holding the target for the federal funds rate at its current setting."
That is the core of his position, and it is deliberately reversible.
That is a pivot from the posture that had dominated since Jackson Hole. Warsh had told the symposium that recent softer monthly inflation readings "do not tell me that underlying trends have meaningfully improved," adding that if trends do not cooperate, "we have work to do." Several members of the rate-setting committee have voiced similar concerns that price increases remain too high. Waller's statement effectively moved at least one of the seven FOMC votes out of the near-term hike column, and in a market where the September decision had been priced as genuinely contested, one vote is enough to move the two-year note.
Waller did not close the door on tightening. He framed his position as data-dependent in both directions: "If the incoming data for August show this improvement has been fleeting, then it may be appropriate to raise the policy rate when the FOMC meets on September 15 and 16." He also warned that "policy is currently only slightly restricting aggregate demand, and it may not take much acceleration in inflation to nudge me into supporting tighter policy," and that "if there is evidence that progress toward 2 percent inflation reversed in August, a small adjustment in our stance would help ensure that it resumes."
The asymmetry in that language is the key. Waller is not arguing that inflation is solved. He is arguing that the current setting is appropriate if the recent momentum continues, and that the burden of proof for a change has not yet been met. For a bond market that had been pricing a meaningful hike risk, that is dovish enough to buy.
The Inflation Numbers Behind the Stance
Waller anchored his case in a specific set of figures. PCE prices are up 3.7 percent over the past 12 months, and core PCE inflation is 3.3 percent. He acknowledged that these 12-month increases have real effects on businesses and consumers, but argued they are "not the best guide for where inflation is today" because they still reflect earlier price shocks from energy and tariffs.
His preferred read is the three-month pace:
"Three-month core inflation is 3.05 percent for the three months through July, a level that is still not consistent with the FOMC's 2 percent goal. Nevertheless, it is important to note the trend. Three-month inflation has fallen steadily from 4.76 percent in February. That is a considerable improvement, and the speed of this downward trajectory is encouraging."
That momentum argument is the fulcrum of the entire dovish case, and it is also its weakest point. A three-month annualized rate is a short window; it can be reversed by one or two hot prints. Waller knows this, which is why he tied his vote to the August data still to come. He also noted that, excluding a volatile imputed component, "underlying inflation is doing better than the core numbers suggest," and that the price effects of tariffs have largely passed through while higher energy prices have not, so far, bled into broader goods and services prices.
On the real economy, Waller painted a picture of solid growth that does not require additional restriction. Real GDP grew at a 1.8 percent annual rate in the first half of the year, and real private domestic final purchases, his preferred measure of underlying demand, rose 3 percent over the same period. Job creation has averaged 60,000 a month through July, close to what is needed to keep pace with a slowly growing labor force, and the unemployment rate edged down to 4.1 percent in July. He expects growth of "a bit more than 2 percent" for the full year.
The Mechanism: How One Governor Moved a Multi-Trillion-Dollar Market
The transmission channel from a single speech to the Treasury curve is straightforward but often misunderstood. The two-year yield does not price the current fed funds rate; it prices the expected path of the policy rate over the next couple of years, plus a small term premium. When the market reassesses the probability of a 25-basis-point move at the next meeting, that reassessment compounds across every expected rate decision embedded in the curve.
Before Waller's remarks, the two-year yield had topped 4.40 percent earlier in the week, its highest level since January 2025, as traders built a hike premium into the front end. The intraday drop of as much as seven basis points to 4.30 percent represents the partial unwinding of that premium. The longer end moved more modestly: the 10-year yield eased roughly three basis points to around 4.77 percent, having recently touched multi-year highs above 4.80 percent. The curve's response was therefore concentrated where the policy decision matters most.
The dollar's move tells the same story through a different channel. The greenback fell as much as 0.5 percent against all Group-of-10 peers. A lower probability of a September hike reduces the relative yield advantage of dollar-denominated assets, which is immediately bearish for the currency. Currency markets price rate differentials faster than bond markets price them, which is why the dollar's reaction was proportionally larger than the move in the 10-year yield.
There is also a positioning dimension. After Jackson Hole, traders had added hike exposure across the front end of the curve and into the dollar. Waller's comments forced a rapid unwinding of those positions, and forced unwinds amplify moves. That is why a speech that changed no policy produced a two-way market move large enough to matter for every duration-sensitive asset in the system.
Cyclical Repricing, Not a Structural Shift
This rally is cyclical, not structural. It is a reassessment of the odds on a single policy meeting, anchored to one inflation print two weeks away. Three pieces of evidence support that call.
First, Waller made his stance explicitly reversible. He did not commit to holding; he said he would be "inclined" to hold if the next two weeks of data cooperate. A structural shift in the rate path would require a durable change in the inflation trend, a revision to the Fed's reaction function, or a lasting change in fiscal or term-premium dynamics. None of those changed on Thursday.
Second, the driver Waller cited is a momentum measure with a short half-life. The three-month core PCE rate falling from 4.76 percent to 3.05 percent is a four-month window. Momentum of that kind can reverse within one or two monthly prints, and Waller himself flagged the reversal risk as the condition that would flip his vote.
Third, the neutral-rate question that dominates the long end of the curve is untouched. The 30-year yield remains above 5.25 percent, reflecting persistent concerns about fiscal deficits, debt supply, and the term premium investors demand for holding long-duration risk. Those forces are structural, and they are orthogonal to whether the FOMC hikes in September. A bond rally built on a single meeting's odds does not reach the long end unless the neutral-rate story also changes, and it has not.
The practical implication is that the rally's durability is bounded by the data calendar. If the August CPI and PCE reports on September 11 confirm the cooling trend, the hold becomes the base case and the front end stabilizes. If they print hot, the hike premium returns quickly, because nothing structural has changed to keep it out.
The Counter-Thesis: Warsh Is Looking at the Level, Not the Slope
The strongest case against the dovish read is that Waller is focused on the direction of travel while the Chair is focused on the destination. Warsh's Jackson Hole point was that softer monthly readings do not prove the underlying trend has improved. With headline inflation at 3.7 percent and core at 3.3 percent, price growth is still well above the 2 percent target. From that vantage point, the level of inflation, not its recent slope, is the problem, and premature confidence risks letting disinflation stall.
Waller's own speech partly validates the hawkish concern. He acknowledged "upside risks to inflation," citing energy prices that remain significantly higher than at the start of the year, pressure on technology goods prices from the AI buildout, and the possibility of further tariff increases. He also conceded that policy is "only slightly restricting" demand, meaning the economy is not being slowed aggressively. If demand continues to run at a solid pace while these upside risks materialize, the case for a hike does not disappear; it strengthens.
There is also a credibility dimension. After the post-pandemic inflation episode, in which the Fed was criticized for declaring victory too early, policymakers have an incentive to demand more evidence before declaring that disinflation is secure. Warsh's caution reflects that institutional memory. A single favorable three-month print, in that view, is not enough to stand pat when the level of inflation remains nearly 1.5 percentage points above target.
The falsifying signal for the dovish read is concrete and observable: if the August CPI or PCE prints at 0.3 percent month-over-month or higher for two consecutive months, the "disinflation is on track" thesis fails, and the probability of a September hike should reprice sharply higher. A single hot print would reopen the debate; two would settle it. Conversely, prints at or below 0.2 percent would effectively remove the hike from the table and could reopen discussion of easing later in the year.
What Comes Next: Scenarios and Time Horizons
The path from here splits by horizon, and the horizons point in different directions.
In the short term, between now and the September 15-16 meeting, volatility will be dominated by the August inflation reports on September 11 and the August employment data. A cool inflation print confirms the hold and keeps the two-year yield anchored near current levels. A hot print revives the hike bet and pushes the two-year back toward the 4.40 percent to 4.50 percent range it tested earlier in the week.
Over the medium term, through year-end, the direction depends on whether the three-month momentum Waller cited, at 3.05 percent, continues toward 2 percent. If it does, the Fed can hold without tightening, and the front end of the curve stabilizes. If momentum stalls around 3 percent, the committee faces a harder choice: accept above-target inflation or risk slowing an economy that is still growing at a solid pace.
In the long term, the structural forces are unchanged. Fiscal deficits, the supply of Treasury debt, and the equilibrium real rate keep a floor under long yields regardless of the September outcome. That limits how far the rally can extend into the 10-year and 30-year sectors, and it is why the curve's response was concentrated in the two-year note.
Three scenarios frame the decision. The base case, priced at roughly two-thirds probability, is a hold at 3.50 percent to 3.75 percent, with the Fed waiting for more evidence before acting. The bull case for bonds is a soft August inflation print that pushes hike odds toward zero and reopens discussion of easing later in the year. The bear case is a hot print that sends hike odds back above 50 percent, triggering a front-end selloff that drags the rest of the curve higher.
For investors, the asymmetry is clear. Duration-sensitive assets, including long-dated Treasuries and growth equities, benefit from a lower near-term hike probability. The dollar and money-market positioning that had priced a higher terminal rate are exposed to further unwinding. Banks holding large portfolios of longer-dated bonds remain vulnerable to any renewed rise in yields, because the structural term-premium story has not changed.
The bond market did not rally because inflation is beaten. It rallied because one Fed governor moved the September meeting from a live hike possibility to a data-dependent hold. That is a much thinner foundation, and it lasts exactly as long as the next inflation print holds.
