Oil price forecasting in 2026 has whipsawed with the politics. During the spring Strait of Hormuz crisis, the only question that mattered was how high prices would go. When a US-Iran framework was signed in June and the strait began reopening, the question inverted to how far down. Then, on July 8, the ceasefire collapsed, fighting resumed, and the war has since widened beyond Iran to damage a Kuwaiti oil facility and open a second chokepoint in the Red Sea. The question is genuinely two-sided, and that is what makes the forecast ranges so wide.

Brent, which peaked near $126 in April and fell toward $70 in early July as the deal held, touched $91.42 on July 20 before settling near $88, with WTI near $82.60. The market is caught between two forces pulling in opposite directions: an oversupplied physical market that wants to drag prices lower, and a widening conflict at the world's most important chokepoint that could spike them higher. Understanding why the ranges are wide is as useful as knowing the numbers.

The Two-Sided Setup

The bearish case rests on supply. The physical market is oversupplied. OPEC+ has raised output for five straight months and holds more than 5 million barrels a day of spare capacity, with Saudi Arabia alone sitting on roughly 3 million, the most since 2009. Saudi Aramco cut its official selling price to Asia by the most in decades. The IEA cut its 2026 demand growth forecast during the crisis and flags a surplus building into 2027, with supply growth running ahead of demand. Weak demand meeting rising supply is the classic setup for lower prices.

There is a catch in that bearish case worth stating plainly, because it is the defining feature of this phase: most of the spare capacity sits behind the same strait that is closing. A surplus stranded behind a chokepoint behaves like a shortage until the chokepoint clears. That is why prices can rise even while inventories and spare capacity look comfortable on paper.

The bullish case rests on the chokepoint, and it strengthened in mid-July. Only eight ships transited Hormuz on July 16 against a peacetime norm near 130 a day, war-risk insurance jumped to a quoted 7.5% to 10% of hull value from roughly 0.25% before the war, Kuwait Petroleum Corporation confirmed damage to one of its oil facilities on July 18, and Yemen's Houthis declared a naval blockade of Saudi Arabia that puts Bab el-Mandeb into play alongside Hormuz. Even so, the market has priced the danger to the route, not a loss of the barrels themselves, because no strike has hit Kharg Island or Iranian export infrastructure, and Iranian flows are reported still running above 1.5 million barrels a day. If that changes, the premium rebuilds fast.

Which force wins the next move depends on politics, not fundamentals, and politics does not come with a known range.

What the Major Forecasters Are Saying

IEA (International Energy Agency) cut its 2026 oil demand forecast by roughly 700,000 barrels a day during the crisis and points to a supply surplus building into 2027, with Gulf flows expected to normalize over time. Its balances lean toward loosening, not tightening, once the conflict eases.

Goldman Sachs carries a base case of Brent around $80 in the fourth quarter with WTI near $75, and about $75 for 2027. It keeps a standing tail scenario alongside it: if Hormuz stays largely shut to tankers for another month, Brent averages above $100 for 2026, with roughly $120 in the third quarter and $115 in the fourth under severe restriction. The gap between that base case and that tail is the whole forecasting problem in one bank's numbers.

JPMorgan is structurally bearish on the medium term, with Brent around $86 in the third quarter of 2026 easing to $80 in the fourth and exiting the year near $78, and a 2027 average closer to $64. It treats a long Hormuz closure as unlikely and expects the surplus to reassert once the fighting stops.

EIA (US Energy Information Administration) publishes monthly Short-Term Energy Outlooks. Its recent baselines put Brent in the mid-to-high $70s as Strait flows normalize and shut-in supply returns, with the explicit caveat that the path depends on how the conflict resolves.

The common thread: over a 6-to-18-month horizon the forecasters lean lower, toward a well-supplied market, while acknowledging a real near-term upside tail if the conflict deepens.

Why the Ranges Are So Wide

Oil price forecasting is difficult even in calm markets. Professional forecasters, futures markets, and the agencies closest to the data routinely miss by $20 to $30 a barrel over a 12-month horizon. This environment keeps the ranges especially wide for three reasons.

The key variable is political. Whether the mediators reopen talks, whether a ceasefire holds, and whether anyone strikes Iranian oil infrastructure are not economic variables with known ranges. They are political ones, and each can move the price by tens of dollars in a day.

The pace of any supply return is uncertain. A signed deal does not move a tanker. Mines have to be cleared, insurers have to lower war-risk premiums, and trapped vessels have to sail. When the June framework held, estimates for full normalization ran from weeks to months. That same uncertainty applies to any future de-escalation.

The size of the surplus is hard to estimate. How much OPEC+ output was held back, how much other producers added, and how soft demand has become all feed into whether the market clears in the $70s, the $60s, or lower once the conflict eases. Those numbers are not yet known.

The Scenario Framework

Rather than a single forecast, most serious analysts work with scenarios. As of mid-2026, three span the plausible range.

De-escalation (Brent low $70s falling toward the $60s). A ceasefire holds or a framework revives, the strait clears, and withheld OPEC+ supply returns into soft demand. This scenario needs a diplomatic opening, and as of the end of July there is not one. The four-night pause in late July collapsed, and Iran rejected Oman's proposal to manage the strait jointly, countering with a demand for one lane inside its own waters and a reported fee of $1 million per ship. Oman has floated a three-route alternative that Tehran has not answered. If something in that channel does hold, the war premium unwinds into more than 5 million barrels a day of spare capacity, and the move lower comes from fundamentals.

Contained conflict (Brent mid-$80s to low-$90s). The current pattern persists: strikes, blockades, and closures raise the cost of moving oil, but Kharg stays intact and the surplus caps the top. Prices grind in a band, supported by the risk premium but unable to break out. This is where prices sit now, and the band has shifted up roughly ten dollars since the July 8 collapse.

Supply shock (Brent $110 to $150+). A strike on or seizure of Kharg removes Iranian barrels at the source, a full sustained closure of Hormuz holds, or the Houthi blockade of Saudi Arabia becomes real interdiction and closes a second chokepoint. Any of the three would force the premium to rebuild from a base that is still modest relative to April. This is the lower-probability, high-impact tail, and it is the main reason prices have not fallen back to the $60s already.

What the Forward Curve Says

The oil futures market is one forecasting tool with money behind it. Through 2026 the Brent curve has swung with the crisis, from steep backwardation at the peak, where near-month prices sat far above later months, toward a flatter structure when the deal held. The back of the curve has consistently traded below the crisis highs, reflecting a market that expects supply to return and the surplus to reassert over a multi-year horizon.

It is not a point forecast. A given level on the late-2027 curve is consistent with many paths: a smooth glide lower, a bumpy range, or a volatile path that averages out. The curve reflects the cost of hedging across those scenarios, not a consensus prediction. What it tells you is direction, and over the longer horizon that direction points below today's spot.

Why Forecasts Are Useful Despite Being Wrong

The point of an oil price forecast is not to predict the number. It is to understand which variables matter most and in what direction they push prices. In 2026 the key variable has been obvious throughout: Hormuz throughput and whether the conflict escalates or eases. The questions now are whether the fighting de-escalates, whether anyone hits Iranian oil infrastructure, and how large the returning surplus proves once it does.

Watching the forecast ranges narrow or widen, and understanding why they move, tells you more about the market than the midpoint number does. The honest summary for 2026 and 2027: the longer-run gravity is downward, pulled by a surplus, but the near-term path runs through a conflict that can rewrite the number overnight, and that has now done so three times in five months.
