"Because of the liquidity crunch globally, some investments in the future may be affected," he said in New Delhi.

He was, however, quick to add that the effect would be minimal and "at least for this year we will achieve our (FDI) target." During the current year he estimated that FDI inflows would surpass the target of USD 35 billion.

Nath said exports continue to be robust, witnessing a 30 per cent growth. "Exports have gone up by 30 per cent and even this month I feel the exports will go up by that much," he said.

The minister said rupee was depreciating against the dollar due to continuous outflow of the currency. "I do not think it is permanent."

Rupee is trading closer to 49 mark now against the US dollar.

Echoing Finance Minister P Chidambaram's views, Nath said the government does not believe in calibrating the rupee.

"In India, we do not calibrate rupee... the government should not intervene unless there are extraordinary and unnatural situations arising," he said.

On the downslide in stock markets, he said external reasons were responsible for the slide. "Our stock markets are going down because of external reasons...Their (the US and EU) liquidity crunch is causing problems in our stock markets."
