$91 Brent Forecast, $123 Spot (World Bank Commodity Outlook, October 2026): Why the Two Numbers Measure Different Barrels — and What a 23% Commodity Surge Means for Currencies

The World Bank's October 2026 Commodity Markets Outlook, published on 28 October, forecasts Brent crude at an average of $91 a barrel this year and $79 in 2027. On the day before, physical Dated Brent was $123.10. The gap is not a forecast that oil is about to fall by a quarter. It mostly comes from two things: an annual average is not a spot price, and the Bank forecasts a different Brent from the one it records as history.

What the World Bank published

The press release leads with a 23% rise in commodity prices in 2026, which the Bank attributes to the Middle East conflict, disrupted grain shipments and El Niño. Deputy Chief Economist Ayhan Kose summarised it as markets "being hit by several major shocks at once." The detail is in the forecast table:

Three revisions stand out. Oil was raised for both years, with 2027 lifted by $9. Wheat was raised sharply, and the Bank expects it to keep rising into 2027. Gold, alone among the war-sensitive commodities, was cut.

The supply numbers explain the oil revision. The Bank projects global oil supply to fall 5.2% in 2026, the largest drop in more than four decades outside the 2020 recession. Consumption is projected to fall 2.5%. When supply falls faster than demand, prices have to rise until enough demand is priced out to close the gap. A 2.5% drop in consumption is a measure of how much rationing by price the Bank thinks has already happened.

Why $91 looks low next to $123

A reader who sees a $91 forecast and a spot price above $120 might conclude that the Bank expects a collapse. That reading mixes up three different things.

First, $91 is an average for the whole year. It includes January and February, before the war began, when Dated Brent averaged roughly $67 and $71 on EIA daily data. It also includes June, when the price fell back into the low $80s. A high spot price in October does not have to match a full-year average.

Second, the forecast is not for the same barrel. Footnote 6 of the Bank's table states that historical Brent numbers reflect Dated Brent prices for physical spot transactions, while the forecasts are for front-month Brent futures. In calm markets the two track each other closely. In a war at sea they do not, because a cargo loading in the North Sea within days is worth more than a promise of oil next month.

Third, the history and the forecast are now pulling apart. On the EIA's Dated series, Brent averaged about $96 across 2026 through 27 October. If the $91 average were measured on that same physical series, the last nine weeks of the year would have to average below $70. That is not what the Bank is saying. It is forecasting futures, and its baseline assumes no major intensification of the conflict. The arithmetic shows how far apart the physical and paper markets have drifted, not that a crash is coming.

The 2027 number is the one that matters

For anyone trading oil-linked instruments, the 2026 average is mostly history. The live question is next year, and the Bank gives two figures for it.

• Baseline: $79. Supply constraints ease gradually and there is no major escalation. Energy prices fall 11.5% in 2027.
• Adverse: $105. The Middle East conflict escalates, damage to Russia's oil infrastructure persists, attacks on Black Sea grain shipments continue and a strong El Niño hits crops, all at once.

The $26 gap between those two numbers is the range of outcomes the Bank thinks is plausible. A futures curve that slopes steeply downward into 2027 is the market's version of the baseline: it says today's tightness is temporary. The adverse case is what happens if that slope turns out to be wrong. Neither number is a target. Each is a statement of what would have to be true about supply.

Why gold was cut during a war

The precious-metals index is forecast to rise 39.9% in 2026, and gold is expected to set a record annual average of $4,600 an ounce, 33.6% above 2025. That is still $100 below what the Bank forecast in April.

The mechanism is the cost of holding something that pays nothing. Energy shocks raise inflation, and central banks in advanced economies have responded by holding rates high rather than cutting. Higher real yields raise the opportunity cost of owning gold, and the Bank names higher interest rates as a drag on non-yielding assets. Safe-haven demand pulls the other way. The revision says that, in the Bank's view, the rates channel has gained ground since April. Our notes on why gold fell during the war and on the dollar–gold relationship cover that tug-of-war in more detail.

What it means for currencies

The outlook reads differently depending on whether a country buys or sells the commodities whose prices are rising.

Energy importers: euro and yen. The Bank sees European natural gas at $19 per mmbtu in 2026, up 58.3%, and Japanese LNG at $20, up 66.7%. Both regions import most of their energy, so higher prices widen their import bills and worsen their terms of trade, the price of what a country sells relative to what it buys. That weighs on the euro and the yen through the trade balance, and it feeds headline inflation, which then shows up in central-bank decisions.

Metals exporters: Australian dollar. Copper is forecast at a record $13,200 a tonne, up 32.7%, and the base-metals index rises 28%. Australia's export mix leans on iron ore more than copper, and iron ore is the exception in the table: the Bank sees it slipping 2.2% to $98 a tonne. That split matters for the Aussie, because a metals boom that bypasses iron ore helps it less than the headline suggests. Our explainer on how commodity currencies work sets out the terms-of-trade channel.

Oil exporters: Canadian dollar. Higher oil is a terms-of-trade gain for Canada, but most Canadian crude is sold into the US at a discount to WTI rather than Brent. A war premium concentrated in physical, waterborne Brent therefore reaches the loonie only partly.

Food: the kiwi and everyone's inflation. The Bank sees food commodity prices up about 10% in 2026 and another 7% in 2027, with US wheat up 28% this year. For importers, food feeds inflation with a lag of several months, which is why a 2027 food forecast can affect rate expectations today. New Zealand exports food, but its main export is dairy, which is not in the Bank's summary table, so the read-across to the kiwi is indirect.

The dollar. The US is a net exporter of oil and gas, so higher energy prices hurt its trade balance less than Europe's or Japan's. For the dollar, the main channel is still inflation and how the Fed responds to it.

What would change the picture

• Hormuz flows. The Bank's baseline depends on shipping recovering. Sustained high-volume transit days would support the $79 path. Repeated near-zero days would push toward the adverse case.
• The physical premium. If Dated Brent stays several dollars above front-month futures, the shortage is still in prompt barrels. A narrowing gap would mean the physical market is catching up with supply.
• Russian infrastructure. The Bank names persistent damage to Russia's oil infrastructure as one of the triggers in its adverse scenario.
• Grain and weather. Black Sea shipping and the strength of El Niño are the inputs for the food forecast, and food is where the 2027 forecast rises rather than falls.
• Rates. If central banks start cutting, the drag on gold that the Bank cites would fade. If they keep rates high for longer, it would persist.

The next Commodity Markets Outlook is due in April 2027. Until then, the forecast is a fixed reference point and the market will move around it. For how commodity prices feed into the meter's currency scores, see how pip theory works.
