The dollar index eased 0.3 per cent to 113.76 by 0956 GMT, backing off from two-decade highs. It had gained almost 4 per cent starting last week on the back of hawkish Federal Reserve comments.
Meanwhile, crude prices hit a 9-month low overnight, having shed 12 per cent this month alone, which bodes well for the rupee as India is a major oil importer.
Local bond settlement rules, tax complexities and the way in which investors will repatriate dollars are among the operational issues that still need to be resolved, said a fund manager at a large global fund. Index investors tend to favour international settlement platforms such as Euroclear but India has said it wants to settle bonds onshore, like China.
