Globally the Indian rupee is likely to open weaker on Tuesday, weighed down by a jump in the dollar index following a steep decline in the euro, as investors digested the implications of the recent U.S.-E.U. trade deal, Reuters reported.

The 1-month non-deliverable forward indicated the rupee will open in the 86.75-86.77 range versus the U.S. dollar, compared with 86.6650 in the previous session.

Asian currencies were mostly nursing modest declines on the day and regional equities were largely weaker.
