Geopolitical tensions in the Middle East have sparked short-term market volatility, driving oil prices higher and shifting investor focus toward inflation risks. Despite near-term uncertainty, strong economic fundamentals and AI-driven growth support

March 16, 2026
Today’s conflict in the Middle East has introduced short-term volatility across all major markets. Oil stocks are one of the major beneficiaries, as a supply shock has occurred due to curtailed production and the closure of the Strait of Hormuz, which has halted approximately 20% of global oil transportation.
Interest rates have generally increased across the yield curve, as inflation expectations mount; the length and severity of the conflict will determine whether higher inflation is a long-term threat or a short-term development. Equity markets have also moved to a "risk-off" stance—a common reaction when geopolitical events surface.
We reviewed previous geopolitical conflicts as a guide, as history can provide important insights. The following table identifies market responses to various military operations dating back to the end of World War II. In 19 of the 20 events, the U.S. equity market fully recovered its initial drawdown within a few months.

While inflation risks are on the rise, we expect the economic growth outlook for 2026 to remain unfazed. Equity markets are projected to generate double-digit earnings growth, with operational efficiencies expanding margins—driven by the broader adoption of AI across various industries and sectors. Major U.S. technology hyperscalers—Amazon, Google, Meta, and Microsoft—are projected to spend U.S. $650 billion on AI-related infrastructure. These expenditures, combined with stimulus injections from developed governments and an anticipated interest rate cut by the U.S. Federal Reserve later this year, serve as tailwinds that will support economic growth.
We continue to monitor overseas events and, as with any such development, are assessing the duration, severity and economic impact of the conflict. While major economies are collaborating to release 400 million barrels of oil from global strategic reserves, this volume represents less than four days of global demand. If oil prices remain elevated, there could be a significant impact on the U.S. consumer, who accounts for approximately 70% of U.S. GDP. However, with the U.S. midterm elections approaching and affordability and inflation remaining primary concerns for Americans, we believe the U.S. administration is mindful of the need for a swift end to the conflict.
Considering the current geopolitical landscape, we are monitoring two primary scenarios and their potential market impacts:
Short Disruption Scenario: If tanker flows normalize within a few weeks and oil prices move back towards $60–$65 per barrel, economic damage would be limited. Historically, geopolitical events alone have not led to sustained equity volatility. Under these conditions, we believe equity markets would likely remain supported.
Prolonged Disruption Scenario: If the Strait of Hormuz remains closed or severely constrained for months -- causing tanker flows to remain near zero -- oil prices will stay elevated long enough to accelerate inflation and dampen growth. A sharp and persistent rise in oil prices poses a significant risk to the current business cycle. In this environment, equity markets would likely face downward pressure as growth headwinds would outweigh near-term earnings support.
Portfolio Positioning
We maintain a well-diversified portfolio and do not intend to reduce our risk exposure at this time. Nevertheless, we continue to tactically evaluate market opportunities and will adjust our positioning as conditions evolve, consistent with the framework outlined above.
The following themes outline our current outlook, including two recent additions designed to optimize the portfolio for the current environment:
