- The Iran conflict, which began in late February 2026, has disrupted global energy trade through attacks on regional refining and production infrastructure and the choking off of tanker traffic through the Strait of Hormuz, yet markets have held up surprisingly well.
- The S&P 500 was trading about 5% below its January record high as of Tuesday's close, per FactSet data, while the ICE BofA U.S. high-yield index option-adjusted spread has seen only a modest rise and long-term inflation expectations show only a modest pickup.
- The crude oil futures curve shows near-month contracts priced significantly higher than those expiring further out, suggesting traders view the supply disruption as relatively short-lived — though 3Fourteen Research's Warren Pies said this reflects a degree of complacency rather than a price forecast.
- Mizuho Securities' macro team described the market reaction as 'a mix of complacency and confidence,' noting that investors are leaning on history — past oil shocks from the first Gulf War, the U.S. invasion of Iraq, and Russia's invasion of Ukraine taught markets that energy disruptions can recalibrate faster than headlines suggest.
- HB Wealth chief market strategist Gina Martin Adams warned that mid-April is seen as a critical deadline; if no resolution is reached, the conflict will 'ultimately result in strains in production into the longer run,' and energy supply shortages in Europe and Asia are expected to grow more acute.
- The March jobs report showed far more jobs created than economists expected, and FactSet analyst John Butters noted that more S&P 500 companies have issued positive Q1 guidance than negative — a backdrop that has helped fundamentals buffer markets.
- President Trump issued an ultimatum to Iran with a Tuesday evening deadline, and even if a deal causes the conflict to de-escalate, there are doubts that oil prices will immediately revert lower.
Why it matters: With the S&P 500 already 5% below its January high and credit spreads still calm, Wall Street strategists warn that missing a mid-April resolution deadline would intensify supply shortages in Europe and Asia and likely blow out the market's current composure.
