The rupee strengthened on Wednesday as oil-related dollar demand waned at the start of the month while custodian banks were spotted selling dollars in a session marked by caution ahead of the U.S. Federal Reserve meeting.
Data confirming India's trade deficit narrowed in June helped ease some of the concerns about the current account deficit that are weighing on the rupee, though the immediate impact on Wednesday was muted.
To build momentum for the rupee, investors would need to see fiscal measures from the government, including action to attract foreign investment, analysts said.
P. Chidambaram appointment on Tuesday as the finance minister was seen as encouraging, given his reformist image, but he will face a skeptical investment audience.
"It is the government as a whole which is responsible for the lack of reforms," said N.S.S. Mani, chief forex dealer at State Bank of Travancore.
"So though Mr. Chidambaram may initiate the process of reforms, whether or not it will be implemented, one has to wait and see. I'm not too confident and don't think the market is too hopeful either."
