NextFin News - Treasury Secretary Scott Bessent expects crude oil to collapse to as low as $40 a barrel once the Iran conflict ends, a plunge he says will drag down bond yields that have lately climbed to their highest levels in years. In an interview that aired Friday, Bessent argued the postwar market will be "very much oversupplied," with prices falling to "$50, $40 crude maybe, just because there's so much coming online."
The forecast, from the official overseeing the administration's "economic D-Day" sanctions campaign against Tehran, sets up a stark tension: the Treasury is actively working to keep Iranian barrels off the market today while betting that a flood of supply will soon push prices toward levels last seen before the war premium took hold. Brent crude traded near $95 a barrel this week, roughly 43% above a year earlier, while the 10-year Treasury yield sat at 4.78% on September 4, up 0.17 percentage points over the past month and near the highest level since November 2023.
The stakes extend far beyond the energy complex. A $40 oil price would be a windfall for consumers and a political gift for a White House that has tied its economic standing to borrowing costs. But it requires a specific chain of events — peace, a reopened Strait of Hormuz, restored Gulf output, and demand that does not recover — that no futures curve currently endorses. Brent's 52-week intraday high of $120.88, set on April 30, 2026, already sits well below its all-time peak of roughly $147 in July 2008, suggesting the war shock, while severe, has not matched the supply catastrophe of the pre-shale era.
The Forecast and the Contradiction
Bessent's numbers imply a more-than-50% drop from current levels. Brent futures opened at $95.75 a barrel on September 4, and West Texas Intermediate was quoted around $90.35 in early trading, according to market data compiled by a price-tracking service. A fall to $40 would erase nearly the entire war-driven rally that followed the outbreak of hostilities on February 28, 2026, when US and Israeli strikes began a months-long campaign that has since spread across the region.
The mechanism Bessent describes is straightforward: a supply surge. The International Energy Agency said in March that flows through the Strait of Hormuz plunged from around 20 million barrels a day before the war to a trickle, forcing Gulf producers to cut total output by at least 10 million barrels a day. Since the war began, the IEA estimates 410 million barrels of cumulative stock draws have tightened the physical market. Once shipping lanes reopen and Gulf fields return to full capacity, that lost volume comes back — and it arrives into a market where demand has already been damaged.
Vitol, the world's largest independent oil trader, warned in April that the conflict had removed as much as one billion barrels a day of production from the market, with losses at the time running between 600 million and 700 million barrels a day. That is the scale of the disruption Bessent expects to reverse. The question is not whether the barrels can return — they can — but whether they will return into a market large enough to absorb them at $40 without triggering widespread shut-ins among marginal producers.
Here lies the contradiction at the heart of the Treasury secretary's outlook. Bessent's own "Operation Economic Outcast," unveiled at the Treasury on August 24, expanded secondary sanctions across digital assets, gold, aviation and shipping with the stated goal to "sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone." The campaign is designed, by design, to keep Iranian oil offline. A $40 oil price requires not only Gulf barrels returning but also a market flush with supply despite the tightest sanctions architecture Washington has ever built against an energy exporter.
The administration has said it likely will not restart large-scale combat operations, preferring economic strangulation instead. That strategy is structurally supportive of higher prices for as long as it remains in place. Bessent cannot simultaneously prosecute the most coordinated sanctions campaign in history and forecast a glut driven by "so much coming online" — unless he is forecasting the end of his own campaign.
Why Yields Are the Real Story
The bond market is where Bessent's forecast carries its heaviest political and economic weight. The yield on the 10-year Treasury note reached 4.78% on September 4, near the highest level since November 2023, according to interbank yield data. Rising yields have tightened financial conditions, pushed mortgage and credit-card rates higher, and become a persistent irritant for a White House that has tied its economic standing to borrowing costs.
Oil is the transmission channel. Crude prices feed directly into inflation expectations, and inflation expectations are the dominant driver of long-term yields when the Federal Reserve's policy rate is already restrictive. The federal funds rate stood at 3.75% in August 2026, leaving the 10-year yield more than a full percentage point above the policy rate — a term premium that markets have demanded as compensation for persistent inflation and swelling government debt.
Bessent's logic runs: lower oil means lower headline inflation, which means the market can accept a lower term premium, which means the 10-year yield falls. On the surface, the arithmetic holds. The IEA expects global oil supply to fall by 4.3 million barrels a day, or about 4%, in 2026 as Middle East hostilities disrupt deliveries. If that disruption reverses, the inflationary impulse reverses with it.
But the second-order path is less clean, and this is where the market's conventional read breaks down. A rapid oil collapse is not purely disinflationary; it is also a signal that demand has weakened more than expected. The IEA already expects global oil demand to contract by 1.6 million barrels a day this year, steeper than the roughly 1 million barrels a day decline it saw the prior month. OPEC, by contrast, still expects demand to grow by 580,000 barrels a day in 2026, though that is 200,000 barrels a day less than it previously forecast. The gap between the consumer agency and the producer group is itself a measure of uncertainty: if the IEA is right, the demand curve has shifted down, and falling oil is a symptom of weakness, not a cause of relief.
If oil falls to $40 because the global economy is slowing rather than because supply is simply returning, the bond market may not rally on disinflation. It may rally on recession fear, compressing yields through a different, darker channel — or it may sell off on the fiscal consequences of a weaker economy, as lower growth widens the deficit and forces more Treasury issuance. The same $40 print can be read as victory or as warning. Bessent is betting the market reads it as victory.
The Cyclical Case and the Structural Counter
Bessent's call is, at its core, a cyclical mean-reversion thesis. It says the war premium embedded in oil prices is temporary, that supply is elastic, and that the market will overshoot to the downside once the shock passes — just as it overshot to the upside when the Hormuz route closed. Energy markets have a long history of sharp spikes followed by long fades once the disruption clears; the 2022 European gas shock, which sent prices to record highs before infrastructure expansion and demand adjustment pulled them back toward prewar levels, is the closest recent precedent.
The evidence for a cyclical read is concrete. The IEA projects that for 2027, assuming de-escalation in the coming months, global supply will outstrip total demand by 4.61 million barrels a day. That is not a tight market; that is a surplus large enough to fill storage and press prices lower. The agency expects inventories to recover to their February 2026 level by the middle of next year if de-escalation takes hold. A market rebuilding stocks is a market telling you prices are too high.
But the structural counter-thesis attacks Bessent's premise at the foundation, and it has three legs.
The first is demand destruction. A 4% supply shock sustained for months does not merely defer consumption; it destroys it. Refineries reconfigure, consumers switch vehicles, and governments accelerate energy-transition policy. The IEA's downward revision of 2026 demand to a 1.6 million-barrel-a-day contraction is not a temporary pause — it is evidence that the demand curve itself has shifted. If demand does not recover to its prewar trajectory, the "oversupply" Bessent anticipates arrives into a smaller market, and prices fall not to $40 but to a level where marginal producers shut in. The cyclical fade becomes a structural reset.
The second is the term premium, which is not an oil story at all. The 10-year yield sits more than 100 basis points above the federal funds rate not because of crude but because investors demand compensation for the United States' fiscal deficit and debt trajectory. Oil falling from $95 to $40 would shave inflation, but it would not reduce the deficit, resolve the debt-ceiling standoffs, or shrink the supply of Treasury issuance. Bond vigilantes, as Bessent has called them, respond to fiscal arithmetic more than to gasoline prices. A $40 barrel helps at the margin; it does not cure a term premium rooted in fiscal credibility. This is the single most important reason Bessent may be right about oil and wrong about yields.
The third is Bessent's own policy. "Operation Economic Outcast" and the accompanying blockade are calibrated to maximize pressure on Tehran, which means maximizing the removal of Iranian barrels from the market. The administration has said it likely will not restart large-scale combat operations, preferring economic strangulation instead. That strategy is structurally supportive of higher prices for as long as it remains in place. The Treasury secretary cannot simultaneously prosecute the tightest sanctions campaign in history and forecast a glut driven by "so much coming online" — unless he is forecasting the end of his own campaign.
Who Benefits, Who Is Exposed
If Bessent is right, the winners are clear. US consumers would see gasoline, heating and airfare costs fall, a direct boost to real incomes. Refiners with access to cheaper crude would see crack spreads widen, at least until product demand weakens. The White House would gain political cover on both inflation and borrowing costs. And the bond market would, in Bessent's telling, follow oil lower, easing pressure on mortgages, credit cards and corporate debt.
The losers are equally clear. US shale producers, many of whom need Brent well above $50 to justify new drilling, would face a capital discipline reckoning. Gulf sovereigns balancing fiscal budgets against oil revenue would see surpluses shrink. And Iran's adversaries would lose the price pressure that sanctions are meant to create — a $40 barrel makes "economic D-Day" far less painful for Tehran.
The asymmetry is worth stating plainly: Bessent's forecast is more valuable to the administration politically than it is likely to be accurate analytically. A Treasury secretary talking down oil is a time-honored tool of economic statecraft, and the market knows it.
What the Market Has Priced In
The current price already embeds a partial version of Bessent's view. Brent at $95 reflects a war premium, but one that has retreated from the $120.88 intraday high set in April. Markets are pricing continued disruption without a full-blown supply catastrophe. The IEA's 2027 surplus projection of 4.61 million barrels a day is already public, already known, and already reflected in forward curves that slope downward.
What the market has not priced is a $40 print. That level would require not merely de-escalation but a full reopening of the Hormuz route, a restoration of Gulf output, a collapse in Iranian sanctions enforcement, and demand that does not recover. It is a tail scenario, not a base case. And the trigger Bessent names — the end of the Iran conflict — has no visible date. The war began on February 28, 2026, and as of early September it continues, with ceasefires breaking and strikes continuing across the region.
What to Watch
Three signals will determine whether Bessent's forecast proves prescient or political. First, the status of the Strait of Hormuz: until the roughly 20 million barrels a day that flowed through the chokepoint before the war is restored, the supply side of the thesis remains hypothetical. Second, the term premium: if the 10-year yield falls while oil stays above $80, it will show that yields are responding to something other than crude — likely fiscal expectations — and Bessent's transmission channel is weaker than advertised. Third, the sanctions regime: any easing of "Operation Economic Outcast" would be the clearest evidence that the administration itself expects the glut it describes.
The falsifying signal is specific: if the 10-year Treasury yield remains above 4.5% while Brent trades above $70 through the end of 2026, Bessent's claim that falling oil will pull yields down is wrong — the term premium has reasons of its own to stay, rooted in the deficit rather than in crude.
"We're going to get on the other side of this Iran conflict, and I expect that oil will come down. We're going to be very much oversupplied in the oil market after this. We can see $50, $40 crude maybe, just because there's so much coming online."

Conclusion: Scenarios and Time Horizons
Short term, oil remains bid by the war premium and yields remain elevated by inflation and fiscal concerns. The gap between Bessent's $40 and the market's $95 is a bet on how quickly the conflict resolves. Medium term, if a durable ceasefire holds and Hormuz reopens, the IEA's projected 2027 surplus of 4.61 million barrels a day becomes real, and prices could fall toward $60–$70 — a meaningful decline, but well short of the Treasury secretary's low case. Long term, the structural question is whether the war accelerated a permanent shift in demand and energy policy; if it did, the postwar market will be smaller than the prewar one, and $40 oil becomes possible only in a deep recession.
The base case is a gradual normalization, not a collapse. The upside case for Bessent's view is a negotiated end to the war followed by a rapid restoration of Gulf output into a weakening global economy. The downside case is a prolonged conflict that keeps the Hormuz route constrained and the war premium — and the yields that travel with it — firmly in place.
Bessent is betting that the war ends, the wells reopen, and the bond market follows oil lower. The risk is that he is right about the oil and wrong about the yields — because the term premium has reasons of its own to stay.
