Oil slides 3% on expectations for US-Iran nuclear deal

Tehran had "sort of" agreed to the terms

Oil prices fell by about $2 on Thursday on expectations for a U.S.-Iran nuclear deal that could result in sanctions easing, while a surprise build in U.S. crude oil inventories last week heightened investor concerns about oversupply.

Brent crude futures were down $1.99, or 3%, to $64.10 a barrel at 0806 GMT. U.S. West Texas Intermediate (WTI) crude futures were down $2.05, or 3.3%, to $61.10.

U.S. President Donald Trump said on Thursday that the United States was getting very close to securing a nuclear deal with Iran, and Tehran had "sort of" agreed to the terms.
