Treasury yields and the dollar fell after President Trump abandoned plans to strike Iran and said talks with the country will resume Monday, while the currency was also hit by a U.S.-Japanese joint intervention to strengthen the yen.

Key to any success in the talks will be whether the Strait of Hormuz can be reopened for safe shipping, paving the way for eventual talks on Iran's nuclear program.

"Markets are starting August with a rare dose of geopolitical relief, as Trump's decision to restart talks with Iran has knocked a large chunk out of the oil-risk premium and given bonds room to rally," Patrick Munnelly, market strategist at the Tickmill Group, said in a note.
