Reuters - The Sri Lankan rupee closed firmer on Tuesday as more foreign investors purchased government securities, while inward remittances remained high ahead of the traditional new year celebrations, market sources said. ** The currency extended gains into a sixth session to end firmer at 174.45/60 to the dollar, compared with Monday’s close of 174.70/85. ** The island nation’s currency gained 2.09 percent in the last six sessions and 4.8 percent so far this year as exporters converted dollars and foreign investors purchased government securities amid stabilising investor confidence after the country repaid a $1 billion sovereign bond in mid-January. ** The country will celebrate traditional new year on April 14. ** Sri Lanka was plunged into political turmoil in October when President Maithripala Sirisena abruptly removed Prime Minister Ranil Wickremesinghe and then dissolved parliament. A court later ruled the move was unconstitutional, and Wickremesinghe was reinstalled as premier. ** Investor sentiment took a big hit as a result of the 51-day political crisis, leading to credit rating downgrades and an outflow of foreign funds from government securities. ** The rupee dropped 16 percent in 2018, and was one of the worst-performing currencies in Asia due to heavy foreign outflows. ** Foreign investors bought a net 1.6 billion rupees worth of government securities in the week ended March 27, the fourth net inflow in six weeks, extending year-to-date net foreign buying to 3.3 billion rupees, the latest central bank data showed. ** The Colombo Stock Exchange index ended 0.19 percent higher at 5,578.43 on Tuesday, its highest close since March 19. ** The benchmark stock index rose 0.31 percent last week, recording its first weekly gain in eight weeks. The index has declined 7.8 percent so far this year. ** The market awaits some positive news from the third and final vote on the 2019 budget scheduled for April 5, market sources said. ** Turnover was 433.7 million rupees ($2.49 million), less than this year’s daily average of 644.1 million rupees. Last year’s daily average came in at 834 million rupees. ** Foreign investors bought a net 16.8 million rupees worth of shares on Tuesday, but they have been net sellers of 5.7 billion rupees worth of equities so far this year. ** The latest budget aims to increase government spending by 13 percent in 2019, during which the presidential election must be held, while it has set an ambitious goal to reduce a large fiscal deficit.
