0935 GMT - U.S. Treasury yields and the dollar rise in European trade as oil prices increase. Iran on Monday said there were no planned talks with the U.S., creating uncertainty after the U.S. recently cancelled planned attacks against Iran in order to allow discussions to proceed. Discrepancy between U.S. and Iranian messaging could sustain safe-haven demand and keep oil prices supported, feeding inflation concerns, says BankPro's Paolo Broccardo in a note. Geopolitical uncertainty is providing the dollar with underlying support, he says. The 10-year Treasury yield rises 2.2 basis points to 4.705%, according to Tradeweb. The DXY dollar index increases 0.1% to 100.013.
