Oil prices were mostly steady, maintaining gains made last week, as prospects for a lasting US-Iran peace deal appear increasingly remote and fears of supply disruptions in the Strait of Hormuz are ever present, Reuters reports.
Brent crude futures were unchanged at $88.55 by 0128 GMT, while US West Texas Intermediate crude futures slipped 14 cents to $82.26 a barrel.
Both contracts gained more than 5 per cent last week following attacks on tankers operated by Abu Dhabi National Oil Company in the Hormuz strait and on a Saudi Aramco refinery.
