Financial markets remain unsettled as the confrontation with Iran unfolds, and Citi analyst Scott Chronert advised investors this week to look to past episodes for context. Chronert highlighted the ongoing uncertainty around how the situation will resolve and identified the Strait of Hormuz as a particularly significant risk point.
In his note, Chronert emphasized that an "effective closure could lead to even higher oil prices than already experienced." That prospect is central to Citi's assessment of near-term market risk, though the firm is not altering its full-year 2026 U.S. equity outlook. Citi nevertheless warned that shorter-term risk is likely as the geopolitical situation develops.
Chronert pointed to several forces currently interacting in markets. He referenced the "AI disruption narrative" and a "significant sell off in S&P 500 Software," but noted that the S&P 500 index is "essentially flat ytd," supported to date by internal rotations among sectors. He cautioned that those internal supports could come under strain if oil prices remain elevated.
To frame possible market dynamics, Citi drew a parallel with the intervention in Libya in 2011. Chronert described that episode as a useful reference point, observing that equities tended to sell off ahead of strikes while oil continued to climb. He added that equities then rallied into the event, a pattern he likened to market responses seen after strikes on Iran's nuclear sites last summer.
Citi also stressed that other macroeconomic shocks shaped the overall market outcome in 2011. The S&P 500 finished that year essentially flat, supported by about 12% earnings growth, according to the firm's account. The implication is that while headline geopolitical shocks matter, a broader set of macro forces can determine annual performance.
The central takeaway from Citi's note is a warning to "be prepared for unintended consequences of the Iran conflict." Those consequences include upward pressure on oil, resulting inflationary effects, and potential economic headwinds. At the same time, Chronert observed that the U.S. market "may be a relative safe haven as oil prices trend higher."
Context limitations: Chronert's commentary focuses on the possible market mechanics given current developments and historical precedent; it does not provide a definitive forecast of outcomes.
