Fears are mounting that the world is heading for an economic blow far worse than the Covid pandemic within weeks as the Iran conflict threatens global oil and gas supplies.
Experts warn it could trigger food shortages, grounded flights and panic-buying as countries risk running out of fuel and energy if key shipping routes remain shut.
Analysts say the crisis is no longer just about rising prices but the risk of a full-blown supply crunch, with some countries unable to secure enough energy to meet demand.
That could trigger a domino effect across the global economy, hitting everything from air travel to food production.
The Strait of Hormuz, a vital artery for global energy, remains at the centre of the crisis, with around a fifth of the world's oil and gas passing through the narrow waterway each day.
Bank of America has warned European gas prices could surge from around €29 to as high as €500 this winter if the strait stays shut for an extended period, far exceeding levels seen after Russia's invasion of Ukraine.
Such a spike would trigger what analysts describe as a full-blown economic emergency across Europe, the UK and large parts of Asia, with energy costs spiralling and industries forced to cut back, The Telegraph reports
The situation has deteriorated rapidly after strikes hit major energy infrastructure in Iran and Qatar, including facilities responsible for a huge share of global gas supplies, with disruption expected to last months or even years as repairs are carried out.
Oil markets are already showing signs of panic, with supplies far tighter than official prices suggest as countries race to secure fuel.
Kurt Barrow, vice-president of oil at S&P Global Energy, warned the world could soon face outright shortages and rationing if the disruption continues.
'If the Strait stays closed for two months, you'll have plants without feedstock and we'll get real rationing. We'll have panic buying and hoarding.'
According to analysts, millions of barrels a day have already been knocked out of the market due to damaged infrastructure and transport disruption, raising the risk that supply chains could seize up entirely if the conflict drags on.
Jeff Currie, an energy expert at the Carlyle Group, warned the knock-on effects could be severe and immediate, hitting everything from travel to food production.
'We may need to ground planes, shut chemical plants and accept lower crop yields.'
He added that oil and gas underpin large parts of the global economy, meaning shortages would not just push up prices but could quickly disrupt transport networks, manufacturing and agriculture.

Jet fuel deliveries have hit $210 in Rotterdam and $240 in Singapore.
There are also growing fears the crisis could worsen further if the conflict spreads to other key shipping routes, particularly in the Red Sea where vital energy supplies also pass through.
'We continue to watch for any signs that the Houthis may enter the conflict and imperil the Red Sea,' said Helima Croft, a former CIA analyst now at RBC Capital.
She warned even limited escalation could send prices surging again and deepen the crisis.
She said: 'Even just a few missiles or drones fired into the Bab el-Mandeb Strait would push oil prices several legs higher.'
