Sri Lankan rupee forwards ended weaker on Thursday on importer dollar demand amid growing uncertainty after the announcement of new tax hikes, dealers said. One-week rupee forwards, which act as a proxy for the spot currency, ended at 145.55/65 per dollar compared with Wednesday's close of 145.45/55.
Spot next ended at 145.45/55 per dollar, weaker from Wednesday's close of 145.30/35.
The spot did not trade below 143.90, seen as the central bank's desired level.
Analysts said the rupee would face downward pressure until any positive news. S&P revised its outlook on Sri Lanka's "B-plus" sovereign credit rating to negative on March 10, a week after Fitch downgraded its rating by a notch to "B-plus" with a negative outlook.
Dealers also said policy uncertainty is deepening with the new taxes, and the capital gains tax may discourage foreign investors.
Sri Lanka will raise value added tax (VAT) and reintroduce capital gains tax to break out of a debt trap, ahead of talks on a $1.5-billion loan it is seeking from the IMF.
The downgrade will be of concern to international investors and market players, analysts said, adding it would push up the cost of government borrowings in the international market, putting pressure on the rupee.
Foreign investors sold 20.6 billion rupees ($142.27 million) worth of government securities in the week ended March 9, data from the central bank showed, taking the total offloaded since December 30 to 56.6 billion rupees.
