April Market Review

March hands back the quarter's gains as the Strait of Hormuz stays shut and inflation anxiety returns

April 2026 Market Review | Clarendon Private Boston Wealth Management

Key Observations

  • In March, Markets gave up much of the gains they had generated for the quarter as the Iranian conflict persisted. Stocks sold off on sentiment and rates rose based on inflation concerns.
  • U.S. technology stocks, in particular software, pulled back the most as investors perceived advancements in artificial intelligence as a threat to those business models.
  • The last day of the quarter ended with markets rallying after optimism that the U.S. and Iran will seek resolution, with a two-week cease fire in place. The motivation for de-escalation may be pressure on the home front with midterms looming, but the robust economic backdrop is resilient enough to absorb the shock while resolution takes shape.

 

Market Recap 

Global stocks retreated in March after a strong start in January and February resulting in the S&P 500 ending the quarter down 4.3%, and the Nasdaq Composite down 6.9%, the worst quarter since 2022. The Iran conflict dominated sentiment from its onset on February 28th. The quarter closed on an encouraging note as the S&P 500 surged 2.9% on the last day of March (its best single trading day of 2026[1]) and potential of a resolution emerged.

Market Recap 3.26

In the U.S., technology was the hardest-hit sector. Software stocks pulled back on concerns that AI investment would erode their competitive value. Over the last five years, software as a service (SaaS) traded at a 50% premium to the broader market[2]. That premium has been erased over the last two quarters. The weakness drove a broad rotation into value stocks across every market-cap tier. Large-cap growth lost 9.8%, while large-cap value gained 2.1%. Small-cap value led all segments, rising 5%, as investors sought defensively positioned, attractively priced companies.

International stocks held up well by comparison, though March returns softened as the Iran conflict came into focus. For the quarter the MSCI EAFE fell just 1.2% and MSCI Emerging Markets slipped only 0.2%, both comfortably outpacing U.S. markets.

Bond markets offered modest stability. The Bloomberg U.S. Aggregate Bond Index was flat with rates climbing through the quarter on inflation concerns tied to higher energy prices which have caused markets to have largely erased expectations for a Fed cut in 2026.

The Hormuz Problem 

Oil not only impacts gas prices but also petrochemicals which is made from oil and natural gas. Petrochemicals provide building blocks for over 95% of all manufactured goods, including plastics, fertilizers, pharmaceuticals, and synthetic fibers. The Strait of Hormuz is the artery through which these inputs reach market. Before the conflict, roughly 21 million barrels per day moved through it, approximately 18% of global supply[3]. As a result of its closure WTI crude oil prices have risen 50% from pre-war levels and non-U.S. grades have risen by 100% or more over the first quarter. The economic toll for such disruption is acute. The Dallas Federal Reserve recently estimated if the Strait remained closed for the remainder of 2026 it would reduce real global GDP growth by 1.3%, roughly equivalent to Mexico's entire economy going dark for a year[4].

Oil 3.26

What We're Watching 

Two signals will define the long-term impact of this conflict.

The first is whether Iran tests its leverage over the Strait of Hormuz. Before this conflict, the idea of an Iranian toll on commercial vessels was not a serious risk scenario. It is now. Nearly 140 ships transit the Strait each day. Iran has floated a $2 million levy per vessel. If implemented, that generates over $100 billion in annual revenue, nearly double its current oil export income of $53 billion[5]. The financial incentive is real. A permanent toll regime would create lasting friction for Western markets.

The second signal is the extent of damage to energy infrastructure. A swift resolution could reopen the Strait within weeks. But physical damage to production and refining facilities is a different problem. Repairs take months, sometimes years. If supply contracts structurally with no credible alternative to fill the gap, the inflationary pressure this conflict has already created may not be resolved when the fighting ends.

Where do we go from here?

The U.S. midterm elections are nearing with gasoline and inflation at the forefront of campaigns with higher prices felt at every fill-up. The challenge remains finding a credible exit. With news about passage on the Strait changing daily, finding a resolution to tame price shocks will be very important ahead of the midterms.

Additionally, we see genuine reasons for measured optimism. Earnings growth is broadening, and shelter costs continue to moderate. Critically, a soft labor market reduces pressure on the Fed to respond to high inflation driven by energy prices. Collectively, these conditions buy time for a diplomatic resolution and create the backdrop under which one can succeed.

In Conclusion

As a result, we are maintaining current positioning and watching evolving conditions closely. Risks remain, chiefly around infrastructure damage and Iran's willingness to negotiate in good faith, we are watching both closely. We maintain our focus on high-quality investments with downside protection. Please do not hesitate to reach out to your advisors with any questions or concerns.
