The stock market should be dominated by non-economic factors this week -- Iran war developments, tariff news, and the summit between Presidents Trump and Xi Jinping. Nevertheless, last week's FOMC results had some market-supportive messages.

Non-Economic Factors This Week, But...

Will Stocks Like A Rate Hike?
The stock market may react positively to a Fed rate hike at this week's FOMC Meeting, while reacting negatively if the Fed does not hike. The markets raised their probability of a Fed rate hike after the high August Core CPI was released on Friday. Are they right? There continue to be mixed considerations.
Possible Stock Market Reaction
Stocks may view a rate hike positively for several reasons. /1/ With the Fed finally moving against inflation, longer-term Treasury yields could fall. The short-end would be taking on some of the anti-inflation work. /2/ Tighter policy now may reduce the extent of tightening needed later. /3/ A tighter Fed could reduce the risk premium in commodity prices. Lower commodity prices, particularly oil, should be a positive for stocks. It also would work to lower longer-term yields.
In contrast, steady Fed policy could lift inflation expectations and prompt further increases in commodity prices and longer-term yields, both of which would be negative for stocks. Also, the risk of Fed tightening after the mid-term elections would increase, possibly by more than if the Fed had moved sooner. So, this risk would continue to weigh on stocks. And, the markets could conclude that the Fed was bowing to pressure from the Administration, damaging its reputation of being politically independent.
Arguments For/Against a Hike
1. While the 0.3% m/m August Core CPI was on the high side, large increases in a couple of components -- Airfares and Lodging Away From Home -- were mainly responsible. Higher fuel costs were likely behind the jump in Airfares for the second month in row. Volatility appears to be behind the bounce in Lodging after the latter dropped in July. The bulk of the Core components were benign. The Cleveland Fed's measure of the median CPI and trimmed CPI both rose only 0.2% in August. So, "fence sitter" FOMC members could decide to keep policy steady despite the high print, blaming it on a "bad" distribution of "noise" and higher oil prices this month. However, they may vote to tighten in response to the stickiness of inflation.
2. A desire not to tighten ahead of the midterm elections could hold back the Fed, as well.
3. However, the Fed's credibility could be in question if it doesn't tighten, particularly since Warsh has emphasized the Fed's intent to bring down inflation. He has said that steady but high inflation is not acceptable. Although the y/y for the Core CPI slipped to 2.4% from 2.5%, it remains above the Fed's 2% target. The uptick in the University of Michigan Survey's 5-year inflation expectations to 3.4% from 3.3%, reported Friday, could add to the concern that the Fed is losing credibility, as could the recent sharp increase in longer-term Treasury yields.
4. Another consideration, away from the latest inflation data, is that the reasons for the 2024-25 rate cuts no longer apply -- /1/ real rates are not higher because inflation fell and /2/ the labor market is not weakening, unlike what appeared to be the case then. Arguably, reversing these cuts could be appropriate. This reason would point to another rate hike later this year even if the Fed hiked this week.
5. In addition, the US economy is being propelled by several independent forces -- AI build-out, defense spending and re-shoring of production. Higher rates are needed to make room for them, given the economy is at full employment. Indeed, as Fed officials like to point out, an AI-caused ratcheting up of productivity growth would require higher market yields. Otherwise, there could be over-investment.

All Eyes On The CPI
The stock market may trade cautiously into the release of the August PPI and CPI on Thursday and Friday, respectively, after the strong August Employment Report. The inflation data may be the deciding factor in persuading FOMC "fence sitters" to vote for or against a rate hike. One fence sitter, Fed Governor Barr, said last week that he may vote for steady policy if the CPI is benign.
A consensus-like August CPI would not eliminate the possibility of a September rate hike, but it would not guarantee one either. Consensus looks for a high 0.4% m/m increase in the August Total CPI, boosted by higher oil-related prices resulting from Iran war developments. A high Total, however, could be dismissed as temporary. In contrast, a consensus-like Core CPI would point to "sticky" inflation, which Fed Chair Warsh says is unacceptable. The Core is expected to print 0.2% m/m, which would equal the January-July average and remain above the Fed's 2.0% target on an annualized basis. The y/y would slip to 2.4% from 2.5% for Core. The downtick could be viewed positively by the Fed and stock market.
A lower-than-consensus print for both Total and Core also cannot be ruled out. Housing Rent (both Primary and Owners' Equivalent) would have to slow from July's 0.3% pace. And, Airfares need to be flattish to down as would some other typically volatile components like Used Car Prices and Lodging Away From Home.
Fed Chair Warsh, in his Jackson Hole speech, referenced a wide decomposition of the PCE Deflator among his arguments to hike rates (see last week's blog). A decomposition of the Core CPI by broad components shows most printing 0.2% or less in each of the past three months (see table below). However, the share was only just above 50% in May and July, when the Core CPI printed 0.2% overall. So, even though the decomposition differs from Warsh's PCE Deflator figures, it still shows that a broadening slowdown among CPI components is needed to achieve the Fed's inflation target. It is not clear whether FOMC fence sitters will need to see a broadening slowdown to keep rates steady and not hike rates. However, a broadening presumably would raise the possibility they will vote to keep policy steady.
Number of Broad Core CPI Components
0.2% or less 0.3% 0.4% or more Core m/m % change
May 8 (57%) 2 4 0.2
June 11 (79%) 1 2 0.0
July 8 (57%) 1 5 0.2
* number in parentheses is % of the distribution 0.2% or less.
The August Employment Report confirmed the Fed view of a solid labor market. Along with upward revisions to June and July, the +162k m/m increase in August Payrolls showed widespread, albeit mostly small, increases among sectors, with notable increases in Manufacturing and Construction. Payrolls in Leisure and Hospitality had the largest swing, rebounding 62k in August after falling 21k in July (mostly in restaurants). Excluding Leisure and Hospitality, Private Payrolls rose 65k in August after +92k in July. These are solid gains in this low job-creation environment.
The Household Survey confirmed the strength seen in Payrolls. The Unemployment Rate was steady at a low 4.1%. The broadest measure -- U-6 -- fell 0.2% point m/m to 7.7%. Both Civilian Employment and Labor Force rose. The Labor Force Participation Rate jumped to 61.6% from 61.4%, after having been in a downtrend since November 2025. The increase could reflect the small sample bias of the Household Survey. So, an upturn has to be confirmed over the next few months. However, it raises the possibility that an improving labor market is encouraging people to resume looking for jobs.
Besides the Payroll strength, the 0.1 Hour increase in the Nonfarm Workweek to 34.4 Hours shows better activity in the economy. Total Hours Worked (THW) rose 0.3% m/m in August, putting it 1.8% (annualized) above the Q226 average. THW rose 1.2% (q/q, saar) in Q226.
The 0.3% m/m increase in Average Hourly Earnings (AHE) in August supports the Fed's view that the labor market is not producing inflationary pressures. AHE has averaged 0.3% m/m since the start of 2025.
Trump's call for the Fed to lower the funds rate threw another wrench into the monetary policy debate, doubling down in a sense on Treasury Secretary Bessent's previous announcement of a shift out of long-dated government financing. Trump's call is puzzling, since it is a widely held belief that Presidential jaw-boning could backfire by pushing Fed officials to act in an opposite way to assert its independence. Perhaps Trump wants to disassociate himself ahead of the midterms from a tightening decision that may happen this month. Whatever the motivation, his jaw-boning is not likely to have an impact on the Fed. Fed officials' views of the economy should be the deciding factors.
