Indian government bonds rose for a fourth straight session on Thursday, tracking US Treasuries, after a Democratic sweep of the US midterm elections drove down crude prices, easing inflation and rate-hike concerns for the world's third-largest oil importer. Democrats pledged on Wednesday to use their decisive midterm victory to rein in President Donald Trump, raising the prospect of two years of political gridlock in Washington. Investors see that as reducing the risk of more disruptive policy outcomes and potentially opening a path towards a resolution of the Iran war.
