Brent dropped $14 in four sessions (20-24 May 2026) after Iran and the US reached an unsigned MOU on 23 May, injecting diplomatic-optimism premium into the forward curve. The fall unravelled most of the war premium built since the Hormuz closure. North Sea Dated had averaged $120.36/BBL in April at the conflict peak.Source: European Oil Markets briefing

How does the Iran conflict affect Brent crude prices?

The Iran conflict removed an estimated 1.5 million Barrels Per Day of Iranian supply from global markets, pushing Brent above $111/barrel. The UAE's OPEC exit compounded the supply shock.Source: Lowdown

What is the Brent crude price today and why is it high?

Brent Crude reached $111.16 on 28 April 2026, the highest post-war close, driven by the UAE's OPEC exit announcement on top of the existing Iran war supply shock removing ~1.5 million bpd from markets.Source: ICE

Background

The North Sea is a marginal sea of The Atlantic, bounded by the UK, Norway, Denmark, Germany, Netherlands, and Belgium. Its global significance derives from the Brent Crude benchmark (BFOET basket), which references approximately two-thirds of globally traded crude oil and trades on the ICE exchange. North Sea production peaked at ~6 million bpd in 1999 and has fallen to under 1.5 million bpd today. Norwegian gas exports via the Gassled system supply Northwest European markets.

Norwegian North Sea gas production via the Gassled pipeline system is a primary swing supply source for Northwest European gas markets. Equinor brought the Eirin field into production in May 2026, routing 27.6 mmboe through Gina Krog and Sleipner into Gassled. Norway's Sodir recorded a second consecutive monthly production decline in March-April 2026, a structural signal that the North Sea cannot readily substitute for Hormuz-disrupted LNG volumes.

The Iran conflict has driven Brent Crude above $110 a barrel, with North Sea Dated averaging $120.36/barrel in April 2026. The benchmark's role as the global oil price reference means that every Hormuz closure update transmits directly into North Sea-priced contracts worldwide. UK and Norwegian producers benefit from the war premium; European import-dependent economies face higher energy bills.

The North Sea crude benchmark, North Sea Dated (the BFOET physical basket), is the primary price anchor for the european-oil-markets topic. In April 2026, North Sea Dated averaged $120.36/barrel, its highest monthly average since 2022, driven by the Hormuz premium following the Iran conflict outbreak.

Through May 2026, the Brent forward curve compressed sharply: front-month Brent fell from $110.34 on 20 May to $96.14 on 24 May, a $14 decline in four sessions, as the unsigned Iran MOU injected diplomatic-optimism premium into the curve. By 29 May, Brent settled at $94.06, widening Brent-WTI to ~$3.55 as the WTI managed-money long unwound faster than the Brent position. The curve is now pricing the seaborne Hormuz-exposed leg (Brent) as structurally long and the domestic pipeline leg (WTI) as structurally short, a positioning structure that concentrates the Hormuz risk premium entirely in North Sea Dated.

For European crude buyers, the North Sea Dated settlement is the cost-of-goods anchor for refinery feedstock procurement. With Brent near $95-97 as of Update #5 and OPEC+ actual output 9.58 mbd below the February baseline due to Hormuz delivery constraints, the North Sea premium over WTI encodes the market's read on when Gulf volumes will return to The Atlantic Basin.
