London’s two largest oil majors came under pressure as easing crude prices and renewed geopolitical optimism weighed heavily on the FTSE 100 this summer.
BP and Shell both slipped on the blue-chip index as the reopening of the Strait of Hormuz removed a key supply disruption that had previously supported elevated oil prices.
The Strait of Hormuz is one of the world’s most critical energy chokepoints, with a significant share of global crude shipments passing through the narrow waterway each day.
Restored shipping through the strait signalled a meaningful reduction in near-term supply risk, which traders and analysts quickly priced into crude benchmarks across global markets.
Optimism surrounding a US-Iran de-escalation added further downward pressure on oil, as diplomatic progress reduced the likelihood of prolonged disruption to Middle Eastern energy flows.
When geopolitical risk premiums unwind, energy stocks are typically among the first to feel the effects, given how directly crude price movements translate into revenue expectations.
BP has been navigating a particularly challenging period, with the company managing a strategic repositioning while also contending with volatile commodity prices across its global portfolio.
Shell, meanwhile, has maintained a more aggressive shareholder returns programme, but falling oil prices can quickly erode the cash generation that underpins buybacks and dividend commitments.
Both companies carry substantial weight within the FTSE 100, meaning their combined decline has an outsized drag effect on the broader London index during periods of sector weakness.
The development raises fresh questions about the near-term outlook for London’s oil majors, as the market recalibrates its expectations following weeks of heightened tension in the region.
Investors will now be watching closely for any signs of renewed instability in the Middle East, as well as upcoming production decisions from OPEC+ that could shift the supply balance again.
For BP and Shell, the path forward depends heavily on whether crude prices stabilise at levels sufficient to support their capital programmes and shareholder return commitments through the remainder of 2026.
