0640 GMT - The dollar rises as hopes for U.S.-Iran diplomacy fade, lifting oil prices and driving investors towards safe-haven assets. U.S. officials said President Trump rejected a proposal for a seven-day ceasefire and told aides he expects to resume bombing Iran after the November midterms, WSJ reports. Higher oil prices support the dollar as the U.S. is a net oil exporter. The dollar is also lifted by expectations that the Federal Reserve could raise interest rates further. The U.S. nonfarm payrolls report on Friday will prove key for these expectations. The DXY dollar index rises 0.2% to 101.181. (renae.dyer@wsj.com)
