Citi Forecasts Rapid Brent Spike to $110–$120/bbl as Supply Disruptions Deepen

Citi says escalating conflict-driven supply interruptions could push Brent crude to $110-$120 a barrel in the coming days under its 50% probability base case. The bank also outlines higher-risk outcomes ranging from a $150-$200 bull scenario to a $65-$70 bear case if diplomatic or strategic developments reopen flows.

Key Points

  • Citi's base case (50% probability) forecasts Brent at $110-$120/bbl amid 4-6 weeks of disrupted flows equating to 11-16 million barrels per day.
  • Bull case (30% probability) projects Brent up to $150/bbl and potentially $200/bbl 'all-in' if Iran attacks wider energy infrastructure or the Strait of Hormuz remains effectively closed through June.
  • Bear case (20% probability) would see prices fall to $65-$70 by year-end only if a rapid U.S.-Iran deal reopens the Strait.

Key forecast and context

Citi, in a note led by Maximilian Layton, the bank's head of global commodities, said on Wednesday that it expects oil prices to climb sharply as conflict-driven supply disruptions intensify. The bank projects Brent crude will rise to between $110 and $120 a barrel in the coming days.


Base case assumptions

The bank's refreshed base case, which it assigns a 50% probability, assumes 4 to 6 weeks of disrupted flows, amounting to as much as 11 to 16 million barrels per day. Citi wrote that "Brent prices will rally as the conflict continues over the coming days, to $110-120/bbl," and said the market will keep rising until it reaches a level that forces political or strategic intervention.

According to the note, such intervention could take several forms: a price or market event that drives the U.S. to end its military operation; more aggressive inventory releases by the IEA or OECD; or a level that prompts global powers to "forcefully re-open the Strait." The bank underscored that escalation risks remain significant.


Alternative scenarios

Citi set out a bull case with a 30% probability in which Brent could "reach $150/bbl" and rise to as much as $200/bbl 'all-in' if Iran attacks broader energy infrastructure or if the Strait of Hormuz remains effectively shut through June.

The bank's bear case, carrying a 20% probability, envisions prices retreating to $65 to $70 by year-end, but only if a rapid U.S.-Iran deal reopens the Strait.


Other commodities

Beyond crude, Citi said it is "very bullish on aluminium," citing low inventories and the prospect of Middle Eastern smelters reducing output. The bank noted such cuts could potentially remove up to 6 percent of global aluminium supply.


Implications and limitations

The note frames a range of outcomes tied tightly to geopolitical developments affecting maritime chokepoints and regional energy infrastructure. Citi's probabilities and price bands reflect the bank's view that market-moving events would need to trigger either policy actions or physical reopening of shipping lanes to contain a sharper run-up in prices.

Risks

  • Escalation of regional conflict that further disrupts oil flows, impacting crude markets and energy-dependent sectors such as transportation and manufacturing.
  • Prolonged closure or effective shutdown of the Strait of Hormuz through June, which would threaten wider energy infrastructure and could push prices toward Citi's upper bull scenarios.
  • Insufficient policy or strategic intervention to reopen shipping lanes or release inventories, leaving global markets exposed to sustained supply shortfalls and price volatility.
