“Ships of the World, start your engines. Let the oil flow!” said Donald Trump on social media after he announced the signing of an interim peace deal with Iran on Sunday. Under the agreement – which Iran acknowledged included a 60-day negotiating period for a final deal – the president said that following retrieval of mines, there would be a “toll free opening” of the Strait of Hormuz.
But many of the finer details remain “unclear”, said The Guardian. There are questions over the “exact timing of the reopening of the maritime route, who will oversee safe passage and whether any conditions will be applied”.
Financial markets have welcomed the announcement, but further volatility could yet hit people’s pockets.

Have oil prices changed?
The price of oil fell to about $83 (£62) per barrel following Sunday’s announcement, its “lowest since the early days of the war”. Then on Tuesday it dipped below $80. In February, before the first missiles struck Iran, each barrel cost around $73. The price peaked at around $120 at the height of the conflict.
Prices are expected to fall in the wake of a prolonged ceasefire, and there are “real grounds for optimism”, said Politico. Damage to oil-specific infrastructure has been “limited”, meaning it could take “as little as six weeks to resume outflows”.
“So that’s the energy crisis sorted, right?” Not so fast.” A combination of damage to wider infrastructure and the continued closure of the Strait of Hormuz has meant roughly 12 million fewer barrels of oil have been produced each day. And they “won’t magically reappear on the market even if the pact holds”.
Will this continue?
The “first big test” of the deal will be whether shipping companies will have enough “confidence” to return the use of the strait to pre-war levels, said The New York Times. If successful, this will free the 250 tankers and 330 cargo ships trapped in the Gulf, according to the BBC, and transport oil around the world. Oil and gas producers in the Gulf nations would then need to re-establish “wells, refineries and other infrastructure”.
Even if all of that were to materialise, European and Asian countries who have historically depended on oil from the region “will face a long wait”. Processing oil takes considerable time. “It is unlikely that the prices of gasoline, diesel and other fuels will return to pre-war levels anytime soon.”
What about inflation?
Despite air fares “surging” and fuel costs “tipping higher”, UK inflation remained at 2.8% in May, said The Independent. This was a “surprise” to economists, who had widely predicted a rise to 3% and “perhaps even beyond” due in part to the war in Iran.
Remaining at this level could imply that the “cost-of-living squeeze will not play out as badly as had been anticipated” earlier this year, even if the “Iran war sent energy costs spiralling”. However, prices are set to rise again later in 2026, leaving savers to make sure their investments are earning an interest rate “well above the rate of inflation”.
What does this mean for consumers?
Food prices in the UK look to be rising more slowly. Should the Strait of Hormuz open freely, fertiliser, which has “soared in costs” and put pressure on farmers, could fall substantially, said the BBC. Jet fuel has already seen a “small fall in price”, with Northwest Europe jet fuel trading at $1,033 (£780) per tonne, compared with $831 pre-conflict and around $1,840 at its peak.
How will businesses be affected?
Beneath the “encouraging headlines” about inflation control, there is a “hidden crisis for businesses”, said The Telegraph. The Iran war triggered one of the largest energy shocks in history, meaning businesses were “swallowing soaring costs to spare shoppers”.
“Input rises” for producers climbed by “8.7% year on year in May”, larger than the 7.9% in April and the highest in more than three years. On the bright side, this means the economy may avoid a dreaded “wage-price spiral”, but conversely lower margins could lead to increased pressure on the employment market.
