Monthly market comment
In September, geopolitical tensions in the Middle East and the associated risks of energy-induced inflation influenced the market environment. Despite temporary hopes of de-escalation, Brent crude prices remained elevated at approximately 100 USD per barrel. US equities recorded minor losses (S&P 500: -0.4%), while tech stocks in the NASDAQ-100 proved resilient (+3.3%), supported by positive momentum in the AI sector. European equities declined more significantly due to interest rate and energy price risks (MSCI Europe: -2.4%). In bond markets, the global surge in yields accelerated substantially. The 10-year US Treasury yield rose by 53 basis points (bps) to 5.28% over the course of the month, marking its highest level since 2007. The 10-year German Bund yield increased by 32 bps, touching 3.59% at times. The primary drivers behind this dynamic at the long end of the curve were growing concerns over rising US national debt on one hand, and robust economic growth coupled with further accelerating inflation rates on the other. At the short end, the Federal Reserve confirmed its restrictive monetary policy. Under the leadership of Kevin Warsh, the Fed raised its benchmark interest rate for the first time since 2023 by 25 bps to a target range of 3.75%–4.00%. Against this backdrop, European corporate bonds fell by an average of 1.4%, while European government bonds declined by 1.5%, while the US dollar appreciated by 2.4% against the euro. Due to higher opportunity costs associated with the elevated real yield level, gold corrected by 6.3% over the month, reversing a major portion of its August gains.
