SINGAPORE: Oil prices fell on Tuesday, with markets ​weighing reports of mediation efforts between the US and Iran against an exchange of ‌fresh attacks between the two and threats of a naval blockade of Saudi Arabia by Yemen’s Houthis.

Brent crude futures fell 96 cents, or 1.1 percent, to $88.26 per barrel by 09:30 a.m. Saudi time. US West Texas Intermediate crude was down 73 cents, or 0.9 percent, ​to $82.50 per barrel, while the more active contract for September delivery slipped 57 cents, or ​0.7 percent, to $81.91 a barrel.

“There’s some hope of de-escalation between the US and Iran. Reports ⁠are that mediators are proposing a 10-day ceasefire, which could put the Memorandum of Understanding (MoU) back on ​track,” ING analysts said in a note, referring to the June interim deal.

However, this won’t be easy as ​major differences remain between Washington and Tehran, while Trump has warned of retaliation after several US soldiers were killed, ING added.

A senior Iranian official told Reuters Tehran had received a proposal from mediators for a 10-day ceasefire in efforts to salvage the deal ​signed on June 17, intended to pave the way for a lasting agreement to end the war ​that began on Feb. 28 with US-Israeli attacks on Iran.
