"The swap agreement is intended to provide a backstop line of funding for the SAARC member countries to meet any balance of payments and liquidity crisis till longer term arrangements are made or if there is need for short term liquidity due to market turbulence," RBI said in a statement.

In May 2012, RBI had announced it would offer swap facilities aggregating $2 billion, both in foreign currency and Rupee, to SAARC member countries -- Afghanistan, Bangladesh, Bhutan, Maldives, Nepal, Pakistan and Sri Lanka.
