Oil Swings from $90 to Over $100 Then Falls 9% as US-Iran Conflict Escalates and Pauses — Economists Warn of Rate Hike Pressure in UK and Australia

Oil prices surged past $100 a barrel amid US-Iran fighting and Houthi naval threats, then dropped 9% when a ceasefire pause was announced.

Brent crude swung by more than $15 a barrel within days as a US-Iran military confrontation and simultaneous Houthi threats to Red Sea shipping created what traders called a 'two-chokepoint problem' for global oil supply. Prices first climbed above $90 when the United States and Iran exchanged fire in and around the Strait of Hormuz, one of the world's most critical oil transit routes. As hostilities intensified, Brent crude crossed the $95 mark and then pushed past $100 a barrel — a psychologically significant threshold — before retreating sharply. The Houthi militia in Yemen added a second pressure point by threatening a naval blockade targeting Saudi crude shipments through the Bab al-Mandab strait, which connects the Red Sea to the Gulf of Aden. Houthi forces also struck tankers in the Red Sea, amplifying fears that Saudi exports could be strangled from two directions simultaneously. The rally reversed when the US announced a pause in its strikes on Iran. Brent crude fell roughly 9%, dropping back below $88 a barrel. The drop was large enough to move UK government bond yields lower, reflecting the relief felt across broader financial markets. Despite the pullback, economists are now warning of broader monetary policy consequences. In the UK, analysts say sustained elevated oil prices could force the Bank of England to raise interest rates, even as it is widely expected to hold rates on Thursday. In Australia, the Reserve Bank is now considered twice as likely to hike rates as a result of higher fuel costs driven by the Middle East crisis. Experts describe the global energy market as at a 'critical juncture,' with the escalating conflict expected to further weigh on an already slowing Australian economy.

Why it matters

The Strait of Hormuz and Bab al-Mandab together handle a significant share of global seaborne oil trade, so simultaneous threats to both routes can drive energy costs higher worldwide. Sustained prices above $100 a barrel feed directly into inflation in importing economies.

What's next

Markets will be watching whether the US-Iran ceasefire pause holds and whether the Houthis follow through on or escalate their threatened Bab al-Mandab blockade.

Key facts

• Brent crude fell approximately 9% to below $88 a barrel after the US paused strikes on Iran
• Oil had previously risen above $100 a barrel as the US-Iran conflict escalated
• Houthi militia struck tankers in the Red Sea and threatened a naval blockade targeting Saudi crude shipments
• The Bab al-Mandab strait and the Strait of Hormuz were both under simultaneous threat, creating what traders called a 'two-chokepoint problem'
• The oil price drop was large enough to pull UK government bond yields lower
• Brent crude climbed through multiple thresholds during the escalation: above $90, then $95, then $100 a barrel

Bias & framing notes

All eight sources are from The Guardian, providing no independent corroboration. The coverage is consistent in its factual trajectory — prices rose then fell — but relies heavily on market reaction and trader sentiment rather than official government statements, leaving the diplomatic and military dimensions underreported. No source surfaces the US or Iranian governments' stated justifications for their actions.
