The numbers are no longer abstract. In the span of a single month, the probability of a U.S. recession has gone from an academic discussion to a live variable repriced daily by some of the most sophisticated financial institutions in the world. Goldman Sachs sits at 30%. EY-Parthenon at 40%. Moody’s Analytics at nearly 49%. Wilmington Trust at 45%. The models are diverging — and how investors read that divergence will shape portfolio decisions for the rest of the year.

The trigger is well understood. The U.S.-Israeli war on Iran, which began February 28, has effectively closed the Strait of Hormuz, the narrow chokepoint through which approximately 20% of the world’s oil supply normally flows. Brent crude, which traded at $72.48 on the eve of the conflict, has since surged to more than $116 per barrel as of Monday — a move of more than 60% in under five weeks. But the recession risk models diverge not because analysts disagree on the oil shock. They diverge on what happens next, and on how vulnerable the underlying U.S. economy was before the war even began.

The Goldman Framework: A 30% Floor, Not a Ceiling

In its weekly U.S. economics update published last week, Goldman Sachs said it now expects Brent crude to average $105 per barrel in March and $115 in April before retreating to $80 by year-end, assuming roughly six weeks of Hormuz supply disruptions. On the back of that revised oil outlook, the bank raised its headline PCE inflation forecast by 0.2 percentage points to 3.1% by December 2026 and nudged its full-year GDP growth estimate down to 2.1%. Goldman also raised its recession probability by 5 percentage points — to 30% — while stressing that a recession is still not its base case.

Goldman’s shift isn’t about a singular shock, but about multiple pressures converging at once. The bank argues that the U.S. economy was already sluggish before the Iran-led oil crisis — before the layered hit from energy, labor, and policy constraints.

One relative reassurance from Goldman: the bank does not expect the oil shock to durably unhinge inflation expectations. Even major energy shocks in recent history did not produce lasting shifts in where consumers and businesses expect prices to settle, though it flagged post-pandemic inflation psychology as a risk worth watching.

Notably, Goldman’s relative optimism is structural. BNP Paribas argues the U.S. is “well-positioned to absorb the shock,” pointing to America’s status as the world’s largest crude producer and net energy exporter — a structural advantage that simply didn’t exist during the oil shocks of the 1970s and 1980s. Higher oil prices redistribute income within the U.S. economy rather than draining it abroad, limiting the macro damage.

EY-Parthenon at 40%: The Cascading Effects Argument

Where Goldman frames the oil shock as a discrete, time-limited supply disruption, EY-Parthenon constructs a more systemic risk case. EY-Parthenon puts recession odds at 40%, citing cascading effects on LNG infrastructure and refining systems beyond the oil market itself.

EY-Parthenon chief economist Gregory Daco told CBS News: “The combination of tighter financial conditions, more uncertainty and higher inflation is going to erode growth.” Daco placed the odds at 40% — up from 35% before the conflict began — with the caveat that those odds could rapidly rise in the event of a more prolonged or severe engagement.

Daco just bumped up his odds, noting that as each week passes, the higher costs and higher risks spread further throughout the economy. “There’s real risk of recession,” said Heather Long, chief economist at Navy Federal Credit Union. “But you don’t want to be the economist who called wolf.”

The EY-Parthenon framework also incorporates what the oil price data alone cannot capture: behavioral transmission. Perhaps the biggest risk to the economy is that rising uncertainty dampens consumer spending, which accounts for roughly two-thirds of U.S. economic activity, and weighs on financial markets, hurting investors. “If you’re a consumer, you may want to hold off on making a big purchase because you’re not sure how the economy is going to look a few months from now,” one analyst noted. “The economy has been propped up by higher-income people, and if they cut back on spending, it could push the economy into a recession.”

Moody’s at 49%: The Threshold That Preceded Every U.S. Recession in 80 Years

Moody’s Analytics’ model has raised its recession outlook for the next 12 months to 48.6%. Chief economist Mark Zandi said: “I’m concerned recession risks are uncomfortably high and on the rise. Recession is a real threat here.” Zandi added: “If oil prices stay kind of where they are through Memorial Day, certainly through the end of the second quarter, that’ll push us into recession.”

Moody’s AI recession model sits at 49% — one tick from the 50% threshold that has preceded every U.S. recession in the past 80 years. Its analysts note that the model could surpass 50% if oil prices continue to surge.

Three Theories on Why the U.S. Keeps Surviving Its Own Recession Calls

Despite the elevated probability readings, the economy has not yet contracted — and the persistence of that pattern has generated its own body of analytical theory.

Economists have identified three prevailing frameworks for why the U.S. economy remains on the edge without tipping over. First, the “rolling recession” theory: several individual sectors have gone into recession while other sectors have boomed simultaneously. In 2022, tech contracted while manufacturing expanded. In 2024, manufacturing contracted while semiconductors surged. This year, energy is having a resurgence, potentially insulating the economy from weakness in financial and retail sectors. Second, the “K-shaped recovery” dynamic, in which robust spending from wealthier Americans balances out the financial difficulties of lower-income households — preventing the broader economy from entering a recession even as many households struggle with affordability. Third, the “front-loading theory,” in which businesses and consumers accelerate purchases ahead of anticipated tariff implementation, temporarily boosting activity before the actual impact lands.

The Data Underneath: Labor, Inflation, and the Fed’s Trapped Position

Regardless of which probability model proves most accurate, the underlying data presents a policy environment with few easy exits. Unemployment has crept up to 4.3%, hiring has slowed to an estimated 67,000 jobs per month, yet inflation remains stubbornly elevated — a combination for which classical monetary policy offers no clean answer.

The New York Fed’s DSGE model, updated through March 2026, projects that growth in 2026 is expected to be more robust and inflation more persistent than predicted in December — with stronger investment driving higher growth and cost-push shocks, possibly capturing tariff effects, as key factors behind elevated price pressures. The Fed notes its forecast was produced before the Iran war and does not incorporate its economic impact.

GDP is on track to grow at a 2% pace in the first quarter, according to the Atlanta Fed’s GDPNow tracker — though this follows a growth rate of just 0.7% in the fourth quarter of 2025, partly the product of the government shutdown. Economists had expected the Q4 drag would translate to a Q1 boost, but the effects appear modest.

The University of Michigan Consumer Sentiment Index fell to 53.3 in March 2026 — a level historically associated with either an active recession or its immediate approach. That reading sat above 70 as recently as late 2025. Consumer sentiment matters because consumption drives roughly 70% of U.S. GDP. When households expect inflation to persist — and at 3.8% expected inflation, they clearly do — they pull forward purchases of durables and cut discretionary spending, accelerating the very downturn they fear.

What Resolves the Divergence

The spread between Goldman’s 30% and Moody’s 49% is not a disagreement about economics. It is a disagreement about geopolitics — specifically, how long the Strait of Hormuz remains effectively closed and whether the diplomatic track produces a resolution before mid-April, when analysts estimate strategic petroleum reserves and other supply cushions begin to run out.

Like his fellow forecasters, Zandi said his baseline expectation is that the warring sides find a diplomatic off-ramp, oil flows again through the Strait of Hormuz, and the economy can avoid a worst-case scenario. If global leaders can find an end to the war soon, the economy again is expected to skirt the gloomiest predictions.

For investors, that framing clarifies the decision framework: the divergence in recession models is not a reason to dismiss the risk, but to price it. The next month of geopolitical signals — and Friday’s nonfarm payrolls report, released to a closed market — will begin to narrow the spread.
