Geopolitical Significance May Outweigh Market Impact
Nanette Abuhoff Jacobson, Global Investment Strategist
The conflict introduces a wide range of potential outcomes with differing market implications. At the time of this writing, oil prices have risen, equities have declined (with European markets under greater pressure due to higher natural gas prices), US Treasury yields have increased, and both the US dollar and gold have strengthened. These moves largely reflect higher risk premia1 rather than a fundamental shift. Absent a sustained disruption to oil supply, I expect them to fade.
Historically, the market impact of US‑involved geopolitical conflicts has tended to be short‑lived, with risk premia reversing over time. Consistent with this pattern, the current US administration has favored short, forceful responses, primarily through air and naval power, to achieve rapid outcomes. Given this approach, and the limited political appetite for a prolonged US military presence in the Middle East, this conflict may prove relatively short‑lived.
What Else Could Impact This View?
Downside risks to this view include:
- A prolonged conflict keeping oil prices in the $85–$100 per barrel range could represent a meaningful supply shock, raising recession risk and increasing political pressure ahead of US midterm elections.
- Escalation risks include significant US casualties; full closure of the Strait of Hormuz, through which oil is transported; or civil unrest in Iran leading to deeper US involvement.
