Brent slips toward $89 on Tuesday as mediation hopes ease war pressure on oil

Crude oil prices edged lower early on Tuesday, July 21, pulling back from the previous session's highest levels in over a month. Brent crude futures for September delivery fell about 35 cents, or 0.4 percent, to around $88.87 a barrel, while U.S. West Texas Intermediate held near $82.47, little changed. On Monday, July 20, Brent had climbed above $90 as the intensifying U.S. and Iran conflict and disruption to Strait of Hormuz traffic tightened the supply outlook.

The pullback was tied to reports that mediators are seeking a ten-day pause in the fighting and to Tehran's confirmation that it had received diplomatic proposals. Even so, reduced tanker traffic through Hormuz and a threatened naval blockade of Saudi Arabia by Yemen's Houthis kept a floor under prices. Swings in oil feed directly into Iran's export revenue, budget and currency expectations.
