Conflict in the Middle East poses some immediate-term challenges for the Indian economy but is unlikely to dent long-term economic growth momentum, an external member of the RBI's rate-setting panel has said. Going forward, there is a need for fiscal and monetary policies to work in a coordinated manner to push GDP growth to a higher trajectory, Nagesh Kumar has said. In the present scenario, a hike in oil prices, exports disruptions and impact on remittances have been identified as the immediate challenges on the growth front, he said.
