September has garnered an unfortunate reputation in the finance industry for being a notoriously difficult month to navigate. The โSeptember Effectโ generally focuses on the idea that S&P 500 returns have been weaker on average in September than in any other calendar month. And while this may be true, thereโs a lot that can happen during any given September.
Thus far, September 2025 has a lot going on!
At the time of writing this (9/15), the S&P 500 is up about 1.9% during the month. That certainly bucks the historical narrative that September can be a tough go! However, the month isnโt over yet, and thereโs plenty of economic data to sift through.
Will the Fed Lower Interest Rates?
By the time you read this, the Federal Reserve will have already held its September FOMC meeting to determine the next steps for monetary policy. Itโs widely expected that the Fed will cut rates by 0.25% at this meeting and lay the groundwork for rate cuts at the next two meetings of the year (10/29 and 12/10). If the Fed cuts rates by 0.25% at each of these three meetings, the target overnight rate will range between 3.5 to 3.75%. While this may not have direct implications for mortgage rates, it should help grease the gears of corporate Americaโs ability to borrow at lower rates.
The reason the Fed would be moving to cut interest rates (if that is indeed the path they follow) isnโt so much due to inflation. Inflation has been relatively tepid, all things considered. Tariffs havenโt placed significant upward pressure on imported goods for the short period of time theyโve been in place, and shelter costs have cooled from the year prior, which has helped offset any price pressure that has materialized. Rather, the Fed would be moving to loosen monetary policy due to the weakening employment picture.
Warning Signs Emerge in the Job Market
For the past few months, the employment picture has been deteriorating. We havenโt arrived at โa point of no returnโ by any means. Weโre still adding jobs throughout the economy, and there are still millions of job openings available. The issue is more so the number of jobs added is slowing, and revisions of prior data suggest the employment picture isnโt as rosy as it once seemed.
Specifically, when we look at what employment expectations look like vs. the number of jobs added each month, we can clearly see the sentiment around job creation has become quite somber. The chart below shows employment expectations dislocating from the trend of positive job growth since the beginning of the year. This expectations survey tends to be a leading indicator of job growth, which suggests there might be further room for job creation to fall in the coming months.

Separately, individuals accessing unemployment insurance has slowly crept higher since the beginning of 2024. There are a few reasons why unemployment could be moving higher. Individuals who were not seeking a job previously could now be reentering the market for a job and claiming unemployment insurance. Skilled workers may also struggle finding jobs in their specific field or work as companies become stricter in their hiring practices. Weโve seen the unemployment rate increase during this time as well, moving from 3.8% to 4.3%.
How Is AI Affecting Unemployment?
Whatโs less apparent is how much artificial intelligence (AI) is replacing entry level jobs. A recent study from Stanford suggests that entry level jobs are being displaced at a greater rate on average than jobs that require greater skill and experience to complete. Thereโs no doubt AI and the loss of job opportunities will be something our economy will need to reconcile in the not-too-distant future.
The good news is despite a weakening employment picture, the monetary and fiscal policy presently in place paints a very supportive backdrop for the economy moving forward. Stimulus from the One Big Beautiful Bill Act will begin making its way into the economy over the next few years. Interest rates are coming down, creating a tailwind for consumers seeking to borrow for purchases or businesses seeking to expand for projects. And while a greater share of consumer spending is coming from the wealthy, we see little reason to be concerned with the aggregate picture of consumption.
