The government is looking at disinvesting small portions of equity in profit-making public sector undertakings (PSUs) other than the navratnas, finance minister P Chidambaram said today.The fall in rupee is not a cause of concern for the government at the moment, he added."We have always said that orderly movements in both ways is acceptable. It is only disorderly movement that would cause concern," Chidambaram said.Asked whether fuel prices would have an impact on inflation, Chidambaram said it was likely to have an effect. "As we said before, the pass through of fuel prices will have an impact on inflation. Inflation is now at around 4.4%. RBI Governor and I have said that we expect inflation to be around 5%, and that is unavoidable," Chidambaram said.The finance minister was also confident about sustaining the trade deficit at the current levels. "We can sustain the trade deficit at the current levels, which means that capital goods are imported and that is good," Chidambaram said.
