FTSE 100 Set to Dip as Brent Crude Surges After US-Iran Ceasefire Expires

The Quick Take

• FTSE 100 is expected to open lower as oil prices surge following the expiry of the US-Iran ceasefire
• Brent crude prices jumped after President Trump declined to extend the ceasefire agreement
• Energy sector stocks face a conflicting signal — oil producers benefit while energy-intensive consumers are squeezed

The expiry of the US-Iran ceasefire, confirmed by President Trump's decision not to extend the arrangement, has driven Brent crude sharply higher and is applying negative pressure to UK equity indices. FTSE 100's projected dip reflects the dual pressure on non-energy UK corporates: higher oil prices raise input costs for manufacturers, airlines, consumer goods companies, and logistics operators, compressing margins across a wide swath of the index. The energy geopolitics dimension also introduces a broader risk premium that historically weighs on equity multiples during periods of Middle East supply disruption uncertainty.

The immediate beneficiaries of the oil price surge are the energy majors — BP, Shell, and their global peers — which see improved revenue per barrel as Brent spot prices rise above futures curves. However, these gains for UK-listed energy stocks may be insufficient to offset selling pressure in non-energy sectors such as consumer discretionary, airlines, and industrials, where fuel costs are a meaningful margin driver. The Brent crude move signals that oil markets are rapidly repricing the risk of a return to active US-Iran tensions with potential supply disruption implications for Middle Eastern producers.

Investors should monitor whether diplomatic channels reopen following the ceasefire expiry, as any indication of renewed negotiations would quickly reverse the oil price spike and relieve FTSE 100 pressure. The Bank of England's response calculus also matters — persistent oil price elevation above $80 per barrel would complicate the BoE's inflation trajectory and potentially delay anticipated rate cuts. UK inflation data in the next print cycle will be a key indicator of whether the oil surge is filtering into broader consumer prices.
