CHICAGO/SINGAPORE, March ‌9 (Reuters) - Oil prices surged ​as much ​as 29% on Monday to their highest since mid-2022 before paring gains to settle about 7% higher, and gold fell more than 1%, as an escalating Iran war squeezed world energy supplies, boosted the dollar ‌and dampened hopes of interest-rate cuts.

Agriculture markets, led by edible oils that are used as biofuel ⁠feedstocks, touched multi-month or multi-year peaks before easing as crude oil markets pulled back from their highs. Aluminium hit four-year peaks on supply worries even ‌as other metals faced headwinds from a ‌stronger dollar.

"The violent reaction stems from the markets seeing no obvious off-ramp in the escalating Middle East conflict, now a high-stakes stand-off where neither side appears willing to blink first," Tony Sycamore, IG market analyst, said in a note.

"The risk ​of more lasting economic damage continues to build by the day."

A rollercoaster trading day began with Iran on Monday naming Mojtaba Khamenei as successor to his father Ali Khamenei as Supreme Leader, signalling that hardliners remained firmly in charge ⁠in Tehran a week into its conflict with the U.S. and Israel.

But surging oil prices reversed, stock markets rebounded and the dollar pared gains as global leaders addressed crude supply ​anxieties and as U.S. President Donald Trump predicted the war could soon be over.

OIL SOARS, RETREATS

Brent futures LCOc1 settled up $6.27, or 6.8%, to $98.96 a barrel and U.S. West Texas Intermediate crude CLc1 rose $3.87, or 4.3%, to $94.77.

Prices turned negative shortly after the settlement following news of a ⁠phone call between Trump and Russian President Vladimir Putin. Reuters reported that sources said the Trump administration was mulling a further easing of sanctions on Russian oil to help tame global energy prices.

In agricultural markets, Malaysian palm oil rose 9% and Chicago soybean oil climbed to ⁠its highest since late 2022 amid the crude oil rally, but later pared their gains. Wheat and soybeans hit their highest since mid-2024 and ​corn reached a 10-month high before closing mostly down. [GRA/]

Gold fell more than 1% as a stronger dollar weighed on greenback-priced bullion, while higher energy costs fuelled inflation concerns and further dimmed the prospects for near‑term reductions in interest rates. [GOL/]

The dollar flirted with a three-month high hit last week, ‌but pared gains after Trump's comments that the war "is very complete" allayed investor worries about a protracted conflict that could disrupt global energy supplies and weigh on economic growth. [USD/]

Oil-driven inflation fears ‌and delayed rate-cut expectations likely strengthened U.S. yields and the dollar, outweighing safe-haven demand and pushing gold down.

Aluminium jumped to its highest in ⁠four years as supply concerns due to the ‌Middle East war intensified.

Benchmark three-month aluminium on ​the London Metal Exchange hit its highest since March 2022 at $3,544 per ton.

Other base metals were weighed down by a firmer dollar.
