After an excellent 2025, we started the year off with a strong January, paused in February, and in March saw the previous two months of gains wiped out by tensions in the Middle East, ending in negative territory. The exuberance of continued economic growth and financial market expansion turned into concern about valuations, persistent inflation and rising geopolitical uncertainty. All three major stock indices were in the red for the quarter, while the fixed income benchmark was flat. Let’s dig into some of the specifics.
Equities
The S&P 500 fell 5 percent in March, leading to a 4.3 percent decline for the first quarter. The more value-oriented Dow dropped just over 5.2 percent in March and 3.2 percent to start the year. Finally, the growth heavy Nasdaq lost 4.5 percent in March, culminating into a dreary 7% tumble for thefirst three months of 2026.
The two main themes that moved the markets were a shift in sentiment around artificial intelligence and the concern over the war in Iran,specifically the closure of the Strait of Hormuz.
Like last year and the one prior, AI was top of mind for investors, but instead of the AI boom helping drive the overall market on theback of mega-cap tech stocks, the focus shifted to what companies could be hurt by AI as these technologies lower barriers to entry and threaten to upend long-dominant business models. The first sector to be impacted was software at the end oflast year, but that broadened into a wider array of industries including financial services, commercial real estate, and logistics.
As we all know, on February 28, the US and Isreal launched attacks on Iran which continued throughout the next month with limited abatement. Since then, the world’s attention has been drawn to the Strait of Hormuz, though which 20% of the world’s oil is transported, along with critical shipments of liquefied natural gas. At the outset, the markets hoped the conflict would be brief, but this essential transit way remains closed as tensions and military activities continue to mount. During this time, oil prices have nearly doubled. There’s the direct impact of the prices consumers will pay at the pump, as well as indirect costs, such as higher shipping expenditures.
Putting this all together, we started the year with continued robust growth projections and the possibility of more Fed rate cuts. Both tailwinds for stocks. But that quickly turned with persistent inflation and concerns over increased prices across the board from gasoline to food, souring investor sentiment.
International Equities
As the planet’s largest oil producer, the US is somewhat more insulated than the rest of the world by the spike in energy prices. This was the driver of performance in the international equity markets. Global developed and emerging market indices down 10% and 13% respectively for March, with both mostly flat on the year. The swings in foreign equity markets were in the same direction as domestic, however were much more pronounced.
Fixed Income
The Bloomberg US Aggregate Bond index ended flat for the quarter after dipping almost 2% in March on the back of rising interest rates and inflation concerns. The 10-year Treasury yield rose from 4% at the end of February to 4.3% by the end of March. The previous market consensus of 2 rate cuts shifted to the possibility of a hike, although unlikely to happen.
The rising interest rate environment in March was primarily driven by the ongoing war in Iran and concerns about the impact of these hostilities on global trade and inflation. Higher energy prices in March could persist for the foreseeable future, which in turn could lead to further inflationary pressure. Short-term interest rates increased during the month as traders pared back expectations for interest rate cuts from the Fed.
What We’re Watching
March was a month of shifting risks for investors, increasing uncertainty and market volatility. While always a latent concern, geopolitical risks have undoubtedly risen, and along with them the possibility of knock-on effects as well, including increased and unrelenting inflation, the possibility of military escalation, and domestically, the forthcoming mid-term elections. All these factors contribute to heightened market concerns.
That said, fundamentals remain relatively solid for now. Companies have shown impressive resilience over the past few years, and continued earnings growth is expected throughout 2026. While headlines can impact markets in the short term, over the long run, fundamentals ultimately drive performance. As long as companies continue to grow, further market appreciationis the most likely path forward.
