September Observations
Seasonal Market Trends Repeat
Historically, September witnesses challenging market performance and this past month was no different. Though parts of the U.S. equity market held up relatively well alongside continued strength in large-cap technology, the broader market experienced meaningful weakness, closing the gap between year-to-date market leaders. Technology and communications were the standout sectors gaining 4.5% and 4.3%, respectively, driven by AI infrastructure and Mag 7 stocks. International equities faced a broad decline from pressure around the rise in global bond yields and higher oil prices. European equities had their first monthly decline in six months. Japan financial markets were pressured again by a difficult interest-rate environment with yields on government debt climbing to multi-decade highs. Emerging market equities were more mixed with Asian technology providing support while rising global yields and higher oil prices were a hinderance for others. Oil prices moved above $100 per barrel during September adding another potential source of inflationary pressure.
Hawkish Fed & Rising Bond Yields
The mid-September FOMC meeting produced a unanimous vote to increase rates by 25bps to a target range of 3.75%–4.00%. This marked the first time in three years the Fed raised rates and first time under Chair Kevin Warsh. The Committee stated that inflation remained elevated, hence the need for a more restrictive stance. However, the biggest development within fixed income markets in September was the sharp increase in long-term Treasury yields. The 10-year Treasury yield increased by 54 bps during the month to 5.29%, its highest level in four years. A mix of catalysts were suggested including inflation concerns, higher-for-longer interest rates, US fiscal policy, and increasing hyper-scaler debt issuance.
US & Japan Execute Joint Yen-Buying
In the third quarter the U.S. and Japan held a rare joint-buying of yen after the currency weakened to its lowest level in roughly four decades, the first coordinated intervention since 1998. The U.S. Treasury reportedly sold euros to buy yen to help protect against a weakening U.S. dollar. Both countries sought benefits from this action: Japan wanted to limit the inflationary effects of a weaker yen while the U.S. was concerned that instability could spill into global markets and possibly raise U.S. Treasury yields.

Asset Manager Commentary
Stable Value Manager
Overall, the wrap contract market is healthy, with 18 active issuers (14 insurance companies, 4 banks). Wrap contracts remain competitive and recent contraction in market capacity has opened up a potential growth opportunity with wrap issuers. This has helped many stable value managers negotiate lower contract fees with most issuers.
US Large Growth Manager
”AI Sleepers” are companies positioned to benefit from the AI buildout that the market has not yet recognized. They can be found outside the tech hardware (chips, memory, optical) cycle where revenues are recognized. Current AI theme is a search for asymmetric risk/reward rather than solely chasing the well-understood hardware narratives.
Chart of the Month
US yields followed the surging trend in yields seen across the global as several developed sovereign bonds faced pressures. While the US economy continues to prove resilient, moving back to a more normal rate environment will create volatility throughout the transition.
