Brent crude has climbed back above the $88–89 mark and, according to some intraday reports, briefly above $91, as an attack on a vessel in the Strait of Hormuz renews concerns about global oil supply. Here's the latest oil price news, why it's moving, and how traders typically approach volatility like this.
Brent crude, the international oil benchmark, was fluctuating around $88.50 a barrel on Monday 17 August 2026, according to Trading Economics, as traders weighed continued geopolitical tension in the Middle East against signs that more oil was moving through the Strait of Hormuz than initially expected.
That picture shifted on Tuesday 18 August, when several market aggregators reported Brent trading above $91 a barrel intraday, citing renewed concern over oil supply following an escalation in the US–Iran standoff. At the time of writing this figure had not been corroborated across all independent data providers — a reminder that in fast-moving news, prices can vary meaningfully between sources within the same trading session.
A vessel was struck by an unknown projectile while transiting the Strait of Hormuz on Tuesday 18 August 2026, the UK Maritime Trade Operations agency (UKMTO) said, according to Al Jazeera. The strike damaged the vessel's engine room and caused a crew casualty; the remaining crew were assisted by the Omani Coast Guard. The Strait of Hormuz has historically carried around a third of the world's seaborne crude oil trading volumes (or a fifth of total global oil supply) making disruption there a persistent watchpoint for energy markets.
Energy costs feed directly into headline inflation measures. A sustained rise in oil prices can put upward pressure on UK inflation figures, which in turn shapes market expectations for the Bank of England's interest rate path. This article does not forecast the Bank of England's decisions — it is intended to explain the mechanism traders watch, not to predict an outcome.
UK inflation figures and labour market data were both due for release this week — traders often watch these releases closely alongside oil price moves for a fuller picture of the inflation outlook.
Trade oil price volatility
Trade commodities with IG
Leveraged products such as CFDs and spread betting let traders take a position on oil prices rising or falling without owning the physical commodity. This is inform-only, educational content — it is not a recommendation to open any specific position.
Trading with leverage means a trader puts up only a fraction of a position's full value as margin, which can magnify both gains and losses. Losses can exceed your initial deposit when trading with leverage.
Many traders use risk management tools, such as stop-loss orders, to help manage downside risk in fast-moving markets like oil — though no risk management tool can guarantee against losses.
Why are oil prices rising today?
Oil prices have risen amid an escalation in the US–Iran conflict, including a reported attack on a vessel transiting the Strait of Hormuz on 18 August 2026, which has renewed concern over global oil supply.
What is the Strait of Hormuz and why does it affect oil prices?
The Strait of Hormuz is a critical shipping route that has historically carried around a fifth of the world's seaborne crude oil. Disruption to shipping through the strait can affect global supply expectations and push prices higher.
How can I trade the oil price?
UK traders can take a view on oil price movements using leveraged products such as CFDs or spread bets, which let you speculate on price rises or falls without owning the physical commodity. These products carry a high risk of loss and are not suitable for everyone.
Is Brent crude the same as WTI crude?
No. Brent crude and West Texas Intermediate (WTI) are different oil benchmarks, sourced from different regions, and can trade at different prices — particularly during periods of regional supply disruption such as the current situation in the Middle East.
