JPMorgan’s oil price forecast has, for the first time since the US-Iran war began, ceased to exist in any meaningful sense. In a note dated 17 September 2026, the bank’s commodities research team, led by Natasha Kaneva, head of global commodities strategy at JPMorgan, alongside analysts Lyuba Savinova and Artem Fakhretdinov, told clients plainly: ‘For the first time since the start of the Iran conflict, we don’t have a baseline view. We simply don’t know how to model the endgame.’
That admission carries weight. JPMorgan is not a house given to public confessions of ignorance. When its commodities desk waves a white flag, the rest of the market tends to notice.
The Red Lines That Were Crossed Anyway
At the outset of the conflict, JPMorgan built its modelling around what it called ‘economic red lines’: thresholds the Trump administration, it reasoned, would be unwilling to breach. Oil above $100 a barrel. Inflation at 4%. Gasoline at $5 a gallon. The yield on ten-year Treasuries at 5%.
The logic was that pain at those levels would force a deal, reopening the Strait of Hormuz, which JPMorgan had expected to happen by June. ‘Six months later, many of those lines have been crossed, yet the exit strategy is less clear, not more,’ the team wrote.
Oil is now trading above $100. The ten-year yield has ticked past 5%. And according to Quartz, citing AAA data, US diesel prices crossed $6 a gallon for the first time earlier in September 2026. Gasoline at the pump remains just below $5, and headline inflation has not yet reached 4%, but the direction of travel is not ambiguous.
What makes the bank’s position more uncomfortable is how sharply reality has diverged from its earlier projections. As recently as mid-July 2026, JPMorgan’s Global Research had forecast Brent crude averaging $86 per barrel in the third quarter of 2026, $80 in the fourth quarter, and $78 at year-end, predicting no ‘long-lasting damage to energy market production.’ Those numbers now look like a document from a different war.
Supply Disruption That Was Supposed to Be Temporary
The bank’s analysts estimated the ‘fair value’ for oil in September at around $90 a barrel. The gap between that figure and the current price above $100 reflects risk premium, not fundamentals: the market is pricing in the possibility of further disruption, not just current supply constraints.
That risk is not theoretical. Yemen’s Houthis, backed by Iran, have seized an area at the mouth of the Bab al-Mandab Strait, a second critical international shipping corridor. The Congressional Research Service noted that when US-Israel military operations began in late February 2026, Brent crude jumped 8% in three days, from $71.32 on 27 February to $77.24 on 2 March. Since then, the disruption has compounded rather than abated.
The International Energy Agency last week cut its global supply and demand forecasts for 2026, projecting world oil supply would fall by 5.7 million barrels per day for the year, the steepest full-year contraction since the Covid-19 pandemic. Stalled diplomatic talks and renewed attacks on shipping lanes are pushing the market toward a deeper shortfall than previously estimated, the IEA warned.
JPMorgan’s analysts are blunt about what this means for assumptions that underpinned their modelling: the idea that global supply disruption was temporary ‘is becoming increasingly difficult to sustain.’
According to the New York Post, JPMorgan delivered its no-baseline message on a conference call with a large institutional investor. A JPMorgan executive authorised to speak to the press said: ‘We continue to publish estimates, but the research team wanted to acknowledge that the end game has become hard to model given the ongoing volatility and a wide range of potential outcomes.’
Against this backdrop, the Federal Reserve moved on 16 September 2026, voting 12–0 to raise its benchmark rate by a quarter of a percentage point to a target range of 3.75% to 4%, according to the Federal Reserve’s FOMC statement. The decision followed data Chair Kevin Warsh had flagged at the Jackson Hole symposium in August: the Fed’s preferred inflation measure, the 12-month PCE price index, stood at 3.7%, while the six-month reading had reached 4.1%, both well above the 2% target, per Warsh’s Jackson Hole speech. At his post-meeting press conference, Warsh described the move as supporting the Fed’s dual mandate, adding that ‘inflation is too high and has been for too long.’ Trump disagreed with the decision.
Trump himself told reporters last week he did not expect the war to end before November’s midterm elections, saying: ‘Right after the election, oil prices are going to be tumbling downward. I think it’s going to take a little bit longer than the midterm.’ The Congressional Research Service has noted that Iran estimated a $40 billion windfall from simply reopening the Strait of Hormuz with Gulf states, which may explain Tehran’s limited urgency to negotiate.
My read is that JPMorgan’s admission matters less as a market signal than as a reality check. If the bank that built its red-line framework on rational actor assumptions is now saying those assumptions have failed, the broader question is whether any model built on the premise of economic rationality survives the current administration. The midterms are the next hard date. Watch what oil does the morning after.
