New Delhi (PTI): Inflation is expected to come down to 6 per cent from the present level of 7.61 per cent in next three to four months, Prime Minister's Economic Advisory Council Chairman Prof C Rangarajan said here Monday.

"Inflation is likely to come down to 6 per cent in next three to four months. Thereafter it can come down to 5-5.5 per cent depending upon the monsoon and other sectors," Rangarajan told reporters on the sidelines of a conference.

He also said the high international crude oil prices will also have an impact on the GDP growth rate. However, it will not 'derail' the growth process.

In January, the council has revised the GDP growth estimates to 8-8.5 per cent for 2008-09, he said, adding the government's fiscal measures will also have some impact on the tax collection.
