Quick Takes
- Equities Narrowed. The S&P 500 declined 0.3% in September while the equal-weight S&P 500 fell 4.8% as mega-cap tech buoyed the index while the median stock declined. Small caps posted their worst month since March 2025 as rising rates weighed on businesses with higher leverage.
- Inflation & Interest Rates. Headline CPI held at 3.4% YoY in August, as gas prices rose 27.4% YoY. Yields continued higher across the curve in September, with the 10Y Treasury closing September at 5.28%, and the 30Y crossing 5.6%, both the highest since 2002.
- The Fed Hikes. The FOMC voted unanimously to raise rates by 25 basis points to 3.75%-4.00% on September 16, the first hike since 2023. The decision followed stubborn energy-driven inflation from the Iran War and a surprise jump in the labor market. The dot plot implies one more hike in 2026.
- Iran War Escalates. Drone strikes launched from Iraq in early September shut down Saudi Arabia’s East-West pipeline, the kingdom’s main export route around the Strait of Hormuz. Brent crude briefly neared $110, before settling near $100 at month-end, widening its premium over WTI crude.
Asset Class Performance
Equities fell in September, with mega-cap U.S. tech stocks holding large caps nearly flat. Internationally, developed markets lagged as a stronger dollar added to losses, while emerging markets AI exposure helped dampen their losses. Bonds sold off broadly as yields rose, with high yield’s shorter duration helping it edge out the aggregate.
Markets & Macroeconomics
Markets in September were driven by the same forces as August, with high energy prices and rising bond yields once again taking center stage. On the energy front, Brent crude surged back above $100 after drone strikes forced Saudi Arabia to take a key oil pipeline temporarily offline, stirring worries over supply and further attacks on critical infrastructure. National average gas prices reached as high as $4.50 per gallon, continuing to weigh on consumers, as the University of Michigan’s consumer sentiment index fell 3.6 points to 48.1 and the Conference Board’s Consumer Confidence index dropped to 81.9 from 89.4. Headline CPI held at 3.4% YoY in August, driven by energy, with other motor fuels up 44.0%, while core CPI eased to 2.4% YoY even as its monthly pace rose to 0.3%. Producer prices pointed to further pressures, with headline PPI rising 0.4% in August and 5.4% YoY. Adding to the Fed’s case is a labor market that remains largely stable. The U.S. added 162,000 jobs in August, surpassing estimates of 55,000 and July’s figure was revised to a gain of 21,000 from an initial decline. The FOMC voted unanimously at its September meeting to raise rates to 3.75%-4.00%, its first hike since 2023, with Fed Chair Warsh describing the move as removing a “dose of accommodation.” The current September dot plot implies an additional rate hike before year-end, with a few late-month releases offering some relief: core PCE held at 3.0% in August after revisions lowered July’s reading, and Q2 GDP rose from 1.5% to 2.2% in its final revision. Bond markets extended their selloff, with the 2Y Treasury rising about 55 basis points over the course of the month as markets priced in a Fed hiking cycle and the 30-year mortgage rate climbed past 7.2% in late September, according to Bankrate.com. In equities, the market cap-weighted S&P 500 hid a broad decline underneath the surface as AI-related tech stocks rallied over the course of the month. According to Bloomberg, the median S&P 500 stock fell 5.1% in September, with the equal weighted S&P 500 falling 4.8%. In comparison, the S&P 500 Information Technology sector returned 4.5% and the Philadelphia Semiconductor Index 9.6% over the same time period.
Bottom Line: The Fed raised rates in September as energy inflation remains, while the market’s resilience increasingly relies on a handful of AI stocks. With the October FOMC meeting and Q3 earnings soon, investors will look to see whether the Fed hikes before year-end.
