# Oil Sees Biggest Weekly Loss Since April on Iran Deal Talk

> Oil futures plunged on Friday, posting their steepest weekly losses since mid-April, as the US and Iran moved toward ending their war. Negotiators cited a tentative 60-day memorandum to halt hostilities and reopen the Strait of Hormuz. Refined products fell 7% to 9% on the week, while an EIA report showed a fifth straight weekly crude inventory draw.

## Why it matters

Expected reopening of Hormuz flows lowers crude and diesel costs, reducing feed transport and processing expenses. The bullish EIA inventory data was overshadowed by geopolitical expectations, so the downside pressure persists unless talks fail.
