MUMBAI (Reuters) -India's central bank is changing tactics in the way it seeks to limit rupee volatility with the use of non-deliverable forwards now overtaking spot market interventions, which draw heavily on foreign exchange reserves, sources said. The Reserve Bank of India (RBI) has traditionally been more active in the local over-the-counter (OTC) spot market to keep the rupee stable. Dollar sales by the RBI in the spot market to slow rupee depreciation can draw heavily on reserves, while selling in the NDF market has a relatively marginal impact, the sources said.
