September Storms Ahead: Markets brace for turbulence amid Trump-Fed rift

The summer trading lull is coming to an end, and September is shaping up to be a month filled with risks. Tensions between Trump and the Federal Reserve, political instability in France, ongoing geopolitical conflicts, tariff uncertainties, and bond market pressures are all converging. Historically, September has brought sharp market swings as investors reassess portfolios, making this period particularly crucial. (Source: Reuters)

Political drama is unfolding in the U.S. as Trump fired Fed Governor Lisa Cook and the head of the Bureau of Labor Statistics. This comes just ahead of the September 5 jobs data release and the Fed’s September 16–17 meeting. Jerome Powell has hinted at a rate cut while warning of sticky inflation, and markets see an 85% chance of such a move. However, concerns about the Fed’s independence are mounting, raising questions about investor confidence in U.S. markets.

French politics are entering a turbulent phase as Prime Minister Francois Bayrou faces a September 8 confidence vote over budget-cut plans. If his minority government falls, President Macron may appoint a new premier or call fresh elections, which could delay crucial budget decisions. Ratings agencies including Fitch, DBRS, and Scope will update their views later in the month, adding to the pressure. Investors worry that French instability could ripple through European markets.

Hopes for peace in Ukraine are fading after the Alaska summit between Trump and Putin failed to deliver progress. Ukraine’s bonds have already surrendered much of their pre-summit gains, while European defence stocks remain in demand amid higher defence spending commitments. Brent crude remains volatile as Russian and Ukrainian attacks on energy infrastructure escalate. Meanwhile, Trump has imposed a punitive 25% tariff on Indian imports linked to Russian oil purchases. Still, energy-sensitive companies and reconstruction firms like Holcim could benefit if positive developments emerge.

Trade tensions are simmering despite preliminary U.S. deals with the UK and EU. Trump continues to target large economies such as India, and the temporary tariff extension with China remains uncertain. Investors are watching closely to see whether it becomes permanent or if a new wave of tariffs will disrupt global supply chains. The tariff overhang remains a significant source of risk for global trade and equities.

Despite risks, stock markets remain at record highs, which many investors view as a sign of complacency. September is historically the weakest month for equities, with the MSCI World Index falling nearly 4% on average each year since 2020. Unlike August, which has often been strong, September’s negative returns underline the potential for a correction and the need for caution.

Bond markets also face their own pressures as governments ramp up borrowing. The U.S., Japan, and Germany will all issue long-dated bonds in early September, testing investor demand. Japan’s 30-year bond yields have surged by nearly 100 basis points this year to record highs, while European yields remain near multi-year peaks. Investors are questioning whether appetite will be sufficient to absorb the supply, raising the risk of volatility in global debt markets.

September is shaping up to be one of the most volatile months of the year, with risks ranging from Fed independence and French political turmoil to ongoing geopolitical tensions, tariff disputes, and bond market stress. As liquidity returns after summer, sharp market swings are likely. Investors should prepare for turbulence and carefully reassess portfolio strategies.
