Wall Street’s biggest new catalyst on September 3 was not an earnings report. It was a shift in Federal Reserve expectations after Governor Christopher Waller said he was leaning toward keeping rates unchanged at the September meeting if upcoming inflation data confirm that price pressures are easing.
The reaction was immediate.
The Dow Jones Industrial Average rose 1.18%, the S&P 500 gained 1.06% and the Nasdaq Composite climbed 1.40%. Treasury yields fell, the dollar weakened and rate-futures markets reduced the probability of a September hike.
That move matters because only days earlier, investors had been moving in the opposite direction. Oil prices had surged, Treasury yields had reached multi-month highs and Fed Chair Kevin Warsh’s Jackson Hole remarks had pushed markets toward a more hawkish interpretation of policy.
Waller did not promise a pause. He changed the balance of probabilities.
His message was effectively: if disinflation is still progressing, the Fed should be patient enough to see whether that progress continues rather than automatically tightening again.
What exactly did Waller say?
Waller said he would support leaving the federal-funds target range unchanged if August inflation data show continued moderation.
The current target range is 3.50%–3.75%.
He emphasized that inflation is still above the Fed’s 2% goal, so the fight is not finished. But he argued that policymakers should “give disinflation a chance” if the next data confirm recent improvement.
That is important because it introduces a different interpretation of the current inflation problem.
The most hawkish view is that oil, tariffs and sticky services inflation justify another rate increase.
Waller’s view is more conditional: some of those pressures may not be persistent enough to justify immediate tightening if underlying inflation is cooling.
He also downplayed the idea that higher energy prices automatically require a stronger monetary-policy response.
That does not mean energy is irrelevant. It means the Fed must distinguish between a temporary price shock and a broad, persistent inflation process.
Why did stocks rally so strongly?
Equities benefited through the discount-rate channel.
Higher expected policy rates usually push Treasury yields higher.
Higher Treasury yields reduce the present value of future corporate earnings, especially for high-growth technology companies.
When Waller reduced the perceived probability of a near-term hike, investors immediately revised the discount-rate outlook.
Technology benefited most.
That is why the Nasdaq outperformed the Dow.
The move was also broad enough to suggest this was not only short covering in one sector. Investors were repricing the macro environment.
Why did Treasury yields fall?
The bond market interpreted Waller’s comments as less hawkish than the policy path priced earlier in the week.
The 10-year yield fell after recently touching its highest level since late 2023.
The two-year yield is even more important for the September decision because it is more sensitive to the expected path of short-term Fed rates.
If the two-year yield continues falling after the September 4 jobs report, it would show markets are increasingly confident that the Fed can wait.
If it reverses higher, the market is signaling that inflation risk still dominates.
Did Waller cancel the September hike?
No.
This is the most important distinction for investors.
Waller made his preference conditional on data.
The next official employment report arrives on September 4 at 8:30 a.m. ET.
The August CPI report arrives on September 11 at 8:30 a.m. ET.
The FOMC meets on September 15–16.
That means the Fed still receives both a major labor-market report and a major inflation report before the decision.
If payrolls are strong and CPI is hot, Waller’s condition for holding may not be satisfied.
If payrolls are soft and inflation cools, the case for no hike becomes much stronger.
How does this fit with weak ADP data?
ADP estimated only 38,000 private-sector job gains in August.
That report already suggested labor demand may be cooling.
Waller’s comments make weak labor data more market-relevant because they show at least one influential policymaker is willing to place more weight on patience.
Still, ADP and official payrolls can diverge significantly.
The market should not assume the BLS report will confirm the same weakness.
That is why September 4 is a genuine binary catalyst.
What about oil and the Iran conflict?
Oil remains a major complication.
A prolonged energy shock can raise gasoline, transport and input costs.
But oil eased from its recent highs as the immediate geopolitical situation became somewhat calmer.
That helped markets accept Waller’s argument that the Fed can wait for more evidence.
The risk is that renewed escalation pushes crude higher again.
If oil moves materially above recent levels and stays there, inflation expectations could rise even if labor data weaken.
That would recreate the policy dilemma.
What is Waller saying about long-term interest rates?
Waller also discussed a deeper structural issue: the neutral interest rate may be higher than in the previous decade.
He argued that the historical “safety premium” attached to U.S. Treasuries has weakened.
Large fiscal deficits, a roughly $40 trillion federal debt burden and intense demand for capital from areas such as AI infrastructure could keep long-term borrowing costs structurally higher.
This is important for equity investors.
Even if the Fed pauses in September, that does not guarantee a return to the ultra-low-yield environment of the 2010s.
The short-term policy rate and long-term Treasury yields are related, but they are not identical.
Which stocks benefit most if the Fed pauses?
High-duration technology and software stocks benefit because lower yields support valuation multiples.
Homebuilders and real estate can benefit if mortgage rates decline.
Small-cap companies can benefit because many have more refinancing exposure.
Consumer discretionary companies can also benefit if lower rates reduce financing pressure.
Banks are more complicated. Lower short-term rates can compress some interest margins, but easier policy can also reduce credit stress.
What could reverse the rally?
The first risk is a strong September 4 payroll report.
The second is a hotter-than-expected September 11 CPI print.
The third is another oil spike.
The fourth is a renewed bond-market selloff driven by fiscal concerns rather than Fed policy.
That last point matters because Waller himself acknowledged that structural forces can keep long yields high.
A Fed pause does not solve the U.S. fiscal problem.
What to Watch Next
Watch the September 4 payroll headline, unemployment rate and average hourly earnings.
Watch the two-year Treasury yield immediately after the report.
Watch September Fed-funds futures.
Watch oil.
Then watch September 11 CPI.
The September 3 rally was not a declaration that high rates are over.
It was a repricing of the probability that the Fed needs to tighten again immediately.
The key question has changed from “How high will the Fed hike?” to:
Can inflation cool enough for the Fed to wait without losing credibility?
