Oil prices have surged. Stock markets have sold off. The Strait of Hormuz, through which roughly 20% of the world’s oil supply flows, has effectively stalled as the threat of attacks deterred vessels from passing through.
The U.S.-Iran conflict has rattled markets in ways that feel impossible to ignore.
But Bank of America has a more measured take. In a research note, BofA analyst Meghan Swiber said the firm’s baseline outlook for the U.S. economy has not materially changed. The risks, she argues, are real but contained — unless one specific thing happens.
That one thing is an oil price spike. And understanding exactly what Swiber means by that could entirely change how investors view this conflict.
What Bank of America actually said about oil and the U.S. economy
Swiber’s message to clients was direct. “U.S. macro risks are likely limited unless there is a pronounced oil spike,” she wrote, according to Investing.com.
The main near-term impact, she added, would be on the timing of Federal Reserve interest rate cuts and the trajectory of the U.S. dollar, not on the broader economic expansion itself.
That is a notably calm assessment, given the scale of what is happening. U.S. and Israeli strikes on Iran began on Feb. 28, killing Supreme Leader Ali Khamenei and triggering Iranian retaliatory missile strikes on Gulf countries hosting US forces. Brent crude surged 10% to 13% within days, briefly pushing above $82 per barrel. Markets priced in fear fast.

Bank of America is not dismissing that fear. It is putting it in context. The U.S. has significant domestic energy production, buffering the immediate shock. Saudi Arabia holds meaningful spare capacity.
And the bank’s own analysis suggests that the conflict, unless it escalates dramatically, is unlikely to derail the economic cycle on its own.
Oil is the only transmission channel that matters
The reason Bank of America focuses so sharply on oil prices is straightforward. Oil is the primary mechanism through which a Middle East conflict reaches the U.S. economy.
Bank of America’s own rule of thumb makes the math concrete. A $10 crude increase pushes personal consumption expenditures inflation up by roughly 0.1 percentage points and trims GDP growth by a similar amount. At current price levels, that is manageable.
The concern is what happens if prices climb significantly higher and stay there, CNBC noted.
A prolonged Strait of Hormuz closure is the scenario that changes the calculus entirely. Global energy analysts estimate a worst-case disruption could push Brent crude above $100 per barrel.
At that level, the inflation impact becomes harder for the Fed to look through, and the growth drag becomes more difficult to absorb.
How an oil spike transmits into the U.S. economy:
- Higher crude prices push up gasoline and energy costs for consumers, effectively acting as a tax on household spending and reducing disposable income.
- Every $10 increase in crude prices adds roughly 0.1 percentage points to PCE inflation and shaves a similar amount from GDP growth, according to Bank of America’s analysis.
- Sustained high oil prices complicate the Fed’s ability to cut rates, forcing policymakers to hold tighter for longer even as growth slows.
- Energy cost uncertainty freezes corporate capital expenditure decisions, particularly in logistics, manufacturing, and transportation-heavy industries.
What this means for the Federal Reserve
Before the conflict escalated, markets were pricing in a clear path toward Federal Reserve rate cuts. That path has now become murkier.
Swiber said the Fed will likely adopt a wait-and-see approach as policymakers assess whether higher oil prices translate into broader inflation or slower growth.
That is a delicate position. If oil drives inflation higher while the conflict simultaneously weighs on consumer confidence and growth, the Fed faces a stagflationary squeeze it cannot easily escape with rate cuts.

Former Treasury Secretary Janet Yellen captured the bind clearly.
“The Iran situation puts the Fed even more on hold, more reluctant to cut rates than they were before this happened,” she said.
U.S. inflation was already running at 2.4% in January, above the Fed’s 2% target, before oil prices moved higher.
The price scenarios energy-sector investors need to understand
Bank of America’s base case is that the conflict will be relatively contained, since U.S. domestic energy production provides a meaningful buffer.
The political incentive for the Trump administration to avoid a sustained oil price spike is real. Prolonged high gasoline prices would weigh on the president’s approval ratings heading into midterm elections.
Oxford Economics takes a similarly measured view, arguing that the oil market is well placed to manage the impact from Iran and that the conflict is unlikely to last beyond two months.
It recommends selling any extreme moves in oil, energy stocks, gold, and defense names, on the view that those spikes will fade as the conflict does not escalate into a prolonged regional war.
The two scenarios shaping the market outlook:
- Base case: The Strait of Hormuz disruption is short-lived, Saudi spare capacity absorbs supply losses, oil prices stabilize, and the Fed holds rates steady before resuming its cutting path later in the year.
- Adverse case: The conflict escalates into a prolonged regional war, the Strait closure extends for weeks or months, Brent crude pushes above $100, inflation reaccelerates, and the Fed finds itself unable to make cuts, even as growth weakens.
Bank of America says investors should watch oil prices
The signal Bank of America is telling investors to track is not the military headlines: It is the oil price.
As long as crude stays in a range the economy can absorb, the bank’s baseline outlook holds. If prices spike sharply and stay elevated, the economic math changes in ways that matter for every asset class.
For now, the bank’s message is one of cautious steadiness. The U.S. economy entered this conflict from a position of relative strength. Consumer spending is holding. Corporate earnings have been beating estimates. The labor market, while softening at the margins, has not cracked.
None of that means investors can ignore what is happening. It means watching the right variable.
Bank of America has made its view clear. The war itself is not the risk — the oil price is.
