Brent Surges Above $87 as Iran Escalation Pushes UK Gilt Yields Past 5%

Fresh US-Iran hostilities and a renewed blockade of Iranian shipping drove Brent crude above $87, lifted gas prices and pushed UK borrowing costs sharply higher.

Fresh US-Iran hostilities and a renewed blockade of Iranian shipping drove Brent crude above $87 a barrel, lifted European gas prices and pushed the UK 10-year gilt yield through 5%.

Oil and gas markets react to renewed escalation

Brent crude rose as high as $87.08 a barrel on 14 July 2026, up 4.55% and its strongest level since 12 June, after Washington and Tehran exchanged attacks and the United States reimposed a naval blockade on Iranian shipping. West Texas Intermediate reached $81.25 a barrel, while European natural-gas prices rose to three-month highs.

The move increased concern about disruption around the Strait of Hormuz, through which a significant share of global oil and liquefied-natural-gas supply normally passes. By the European market close, Brent remained around $85.78, approximately 3% higher on the day.

Why it matters

Higher oil and refined-product prices could renew UK inflation pressure, reduce the scope for Bank of England rate cuts and raise operating costs across transport, manufacturing and consumer-facing sectors. UK government borrowing costs also increased, with the 10-year gilt yield moving above 5%, creating a further headwind for public finances, mortgages and rate-sensitive equities.

UK-listed energy producers including BP plc (LSE: BP.) and Shell plc (LSE: SHEL) may benefit from higher realised commodity prices, while airlines, logistics businesses, retailers and other energy-intensive companies face increased cost risk.
