“Oil, gas and borrowing costs surge as fears over Middle East escalate”
What actually happened
Brent crude pushed back above $100 a barrel and on toward $105 as the US-Iran conflict in the Gulf intensified and the Strait of Hormuz was effectively closed to shipping. UK wholesale gas broke above 200p a therm for the first time since 2022, partly on the conflict and partly on low European storage ahead of winter. Separately, US and UK long-term government borrowing costs hit multi-decade highs, which analysts linked to the inflationary pressure of rising energy costs rather than the conflict directly.
Key facts
- Oil jumped to $105 a barrel, with Brent crude back above $100 on Wednesday and still climbing.
- The Strait of Hormuz has been effectively closed, cutting Gulf oil and gas supply to global markets.
- UK gas rose above 200p a therm, its highest since the end of 2022, driven by both the conflict and Europe's below-normal storage levels ahead of winter.
- US and UK long-term borrowing costs surged to their highest level in decades, which IG's Chris Beauchamp tied to markets waking up to the economic impact of the oil crisis rather than direct war risk.
- Related escalation: Iran-aligned Houthi forces reportedly seized Yemen's port of Mokha, a key Red Sea shipping route, raising fears of further disruption. Broader wire coverage independently corroborates the underlying conflict driving this price action: Al Jazeera reported the same US-Iran standoff over the Strait of Hormuz had pushed Brent crude up more than 4 percent as the US and Iran traded attacks amid their escalating standoff over control of the critical waterway, with prices at that earlier stage still in the high-$70s, consistent with the further climb to $105 described in this later BBC piece.
What to watch for
Watch whether the Strait of Hormuz closure becomes a sustained supply shock or a short-lived spike, that distinction determines whether $105 oil is a peak or a floor. Also watch UK/US bond auctions in the coming weeks: if yields keep climbing on inflation expectations even as energy prices stabilise, it confirms the borrowing-cost story is about inflation psychology, not just direct conflict risk, a nuance this headline compresses but doesn't distort.
