Finance Minister Pranab Mukherjee has said, the steep fall in the rupee was a matter of great concern and the Centre was trying to resolve the situation. Addressing the media in Kolkata today, he said, this situation is due to the Eurozone crisis. Mr. Mukherjee said, there is also currency crisis in emerging markets including Brazil. At the forex market, the domestic currency has been falling against the US dollar over the past few days. Dealers said strong dollar demand from importers, mainly oil refiners, on expectation of further strengthening of the dollar, caused the rupee's fall. However, the Reserve Bank had stepped in and stemmed the rupee's slide.
