(FOX NEWS) — The U.S. dollar traded below a six-week high on Thursday, easing as investors grew optimistic that Washington could be nearing an agreement with Tehran to end the conflict in the Middle East, Reuters reported.

President Donald Trump had said Wednesday negotiations were in their “final stages” but warned that additional attacks could follow if Iran failed to reach a deal.

“We’ll see what happens. Either we have a deal or we’re going to do some things that are a little bit nasty, but hopefully that won’t happen,” he said.

Brent crude futures had fallen $6.64, or 5.97%, to $104.64 per barrel by 1:45 p.m. EDT, and U.S. West Texas Intermediate futures were down $6.49, or 6.23%, to $97.66, Reuters said.
