Indonesian Finance Minister Sri Mulyani said on Monday that the country's economic growth in the second and third quarters would be slower than in the first quarter which stood at 4.4 percent. 'The growth at the second and the third quarter would be fast, but they are not as fast as that of the first quarter,' he told reporters at her office here. The minister said growth at the second and the third quarters would be driven by domestic consumption including the government spending. 'The domestic spending is good enough at the second and the third quarters, it grow above 5 percent,' she said. Islamic fasting month of Ramadhan and Islamic festivity will also contribute to economic growth at the third quarter, said Mulyani. The cut rate by the central bank for a seventh straight month by 25 basis points up to 7.0 percent on May 5 was also expected to spur credits growth, she said. The Indonesian government is optimistic to achieve 4.5 percent economic growth this year. The International Monetary Fund (IMF) revised up its economic growth assessment to Indonesia to between 3 percent and 4 percent amid signs that confidence is returning to the economy following market pressures in late 2008. The international body predicted in April that the country's economy would slow to 2.5 percent in 2009.
