U.S. Treasury yields experienced a slight uptick on Monday as tensions between the United States and Iran resurfaced. The 10-year Treasury yield increased to 4.267%, while the 2-year yield rose to 3.73%. The 30-year yield remained mostly stable. This follows Iran's announcement on Friday that the Strait of Hormuz would be fully open to commercial shipping, only to regain control over the passage on Saturday. U.S. President Trump announced that negotiations with Iran would resume on Monday in Islamabad, Pakistan. However, Iran's Foreign Ministry has stated there are no current plans for further talks with the United States. Investors are also keeping an eye on upcoming crude oil inventories and initial jobless claims data this week.
