Hormuz, Oil, and the Next Test for U.S. Stocks

As of March 30, 2026, the market is no longer treating the U.S.-Iran war as a distant geopolitical story. It is treating it as an energy shock with direct consequences for inflation, rates, and equity valuations.
The reason is simple: the Strait of Hormuz remains the critical pressure point for global supply, and roughly one-fifth of world oil consumption normally moves through that corridor. When shipping risk rises there, oil does not need a full physical blockade to surge; fear, insurance costs, and disrupted flows are enough.
Right now, analysts are framing oil in scenarios, not certainties.
The softer view comes from the EIA: if flows gradually normalize, Brent could average around $91 in the second quarter and fall back later in 2026
with Barclays pointing to an $85 full-year path if transit improves quickly. But if disruption lasts through late April or May, Barclays sees Brent repricing toward $100 to $110.
The harder view is the tail-risk case: Societe Generale sees a possible April average near $125 with credible spikes to $150
while Morgan Stanley warns that oil holding in the $150 to $180 range would become a serious valuation problem for global equities.
For the U.S. economy, the real issue is not just gasoline prices. Higher oil feeds into transport, manufacturing, food, and fertilizer costs, which is why the IMF is warning that this conflict points toward higher prices and slower growth if it drags on. The Federal Reserve is not signaling panic yet, but Jerome Powell has said the Fed is in wait-and-see mode, and Governor Michael Barr has warned that another energy shock could lift inflation expectations and make inflation harder to control.
That means the most realistic market risk is not an immediate policy shock, but a higher-for-longer rate backdrop in which expected rate cuts disappear and the cost of money stays elevated.
What shall stock traders expect?
Expensive energy and stubborn inflation usually compress multiples before they fully hit earnings. Recent trading already shows the pattern: energy and utilities have held up better, while technology and communication stocks have taken heavier pressure, and major U.S. indexes have slipped into or near correction territory since the war began.
Reuters also reported JPMorgan’s estimate that each sustained 10% rise in oil can shave 15 to 20 basis points from GDP, and that oil near $110 for the rest of 2026 could cut S&P 500 earnings expectations by 2% to 5%. In other words, if Hormuz remains impaired, this stops being just an oil story and becomes a broader stagflation trade.
The market’s next move depends on duration.
If Hormuz risk fades and flows recover, oil probably cools and equities regain their footing.
If the conflict expands, inflation pressure stays alive, rate relief gets pushed further out, and U.S. stocks face a tougher reset in both sentiment and valuation.
That is the real question for investors now: is this a temporary energy spike, or the beginning of a longer period of higher inflation, tighter money, and lower equity multiples?
