Inflation, the Fed, Geopolitics: Ingredients for a More Volatile Autumn

Unlike what often happens at this time of year, the summer turned out to be rather calm on financial markets. The main topics of debate and concern remained the same: negotiations on tariffs—and their impact on inflation and economic growth, geopolitical tensions, and the evolution of the U.S. Federal Reserve’s policy.
Unlike what often happens at this time of year, the summer turned out to be rather calm on financial markets. The main topics of debate and concern remained the same: negotiations on tariffs—and their impact on inflation and economic growth, geopolitical tensions, and the evolution of the U.S. Federal Reserve’s policy.
International Trade: Between Fragile Truces and Persistent Tensions
A few agreements were reached this summer on tariffs (with the United Kingdom, the European Union, and Japan), although some remain incomplete (such as the ongoing discussions regarding taxes on pharmaceutical products). In addition, certain countries, such as India, have decided to retaliate. As for the U.S.–China discussions—undoubtedly the most complex and most significant given the size of the U.S. trade deficit with China—these continue following the extension of the truce between the two countries. Meanwhile, it is worth noting the solid performance of Chinese equities, which remain undervalued and benefit from hopes of government-led measures to boost consumer spending.
Inflation and Growth: The Federal Reserve’s Dilemma
Given this context, the key question economists are asking is: what will be the consequences of these tariff hikes on inflation and economic growth? The challenge here lies in estimating to what extent higher import prices will be passed on to the end consumer. While companies have so far managed to cut costs and thereby limit price increases, this may not last if they want to preserve their profit margins at current levels.
For now, the latest figures show that inflation in the United States rose to 2.7% in July. At the same time, economic growth is slowing, both in the U.S. and in Europe—a fairly logical outcome, as uncertainty does little to encourage corporate investment.
And so the question arises once again regarding U.S. interest rates and monetary policy: if these trends continue (higher inflation and weaker growth), will the Federal Reserve decide to cut rates in order to support growth? Up until now, its chairman Jerome Powell has remained cautious, resisting relentless pressure from Donald Trump. And last week, in his speech at the traditional Jackson Hole symposium, he once again summarized the complexity of the situation: “The risks to inflation are tilted to the upside, and the risks to employment to the downside.” But he emphasized the latter point, thereby opening the door to a possible rate cut—a genuine turning point. Markets now expect a rate cut as early as September. The question remains whether more will follow, and how investors will interpret such moves. In the meantime, this environment continues to weigh on the dollar, which has lost around 10% against other major currencies since the start of the year.
Companies and Equities: Strong Results but Limited Upside Potential
No back-to-school outlook would be complete without mentioning corporate health, a crucial factor for equity markets in general, and even more so when it comes to large U.S. technology companies. Once again, these companies reported solid earnings this summer and expressed optimism for the future, with continued strong demand for investment in artificial intelligence. As a result, the Nasdaq and S&P 500 indices have climbed back above their levels at the beginning of the year, with valuations once again relatively high.
What to Expect This Autumn?
Most likely, more volatility on the markets, due to the numerous uncertainties: the Fed, inflation, slowing growth, political risks (with France setting a poor example in recent days), and corporate margins.
And probably only limited upside potential. After a strong start to the year, some investors may choose to lock in part of their gains, particularly on equities.
