Sri Lanka has a dollar soft peg, where the central bank tries to control both the exchange rate and the interest rates.
The peg which was around 110 rupees to the US dollar came under pressure from high credit growth and lower than needed interest rates from around the third quarter of 2011.
Sri Lanka's foreign reserves hit a high of 8,050.1 million US dollars by end August following the sale of a sovereign dollar bond, but the peg was already under pressure at the time.
In November the peg was re-set at 113.90 in a surprise budget decision, and dollar sales to defend the peg and liquidity injections to 'sterilize' the shortages in money markets are continuing at the new level.
But interest rates have adjusted upwards from the second week of September, which analysts say can reduce the underlying pressure on the peg.
