"The corporate level foreign currency deficit since 2007 grew at a compounded annual rate of 17.8 per cent to Rs 6,353 billion in FY'13," the India Ratings said in a report today.
During these six years, the share of foreign currency in the total revenues of BSE-500 companies grew to 20.1 per cent at an aggregate level from 17.1 per cent, while their forex expenditure grew to 41.8 per cent from the 38.6 per cent.
"As may be expected, in a net importer nation such as India, its largest corporates on aggregate had more foreign currency outflows than inflows," the report said.
Over half of the companies which account for 70 per cent of the balancesheet debt are net foreign currency spenders who are expected to suffer a pre-tax margin compression of 1.3 per cent in rupee terms for every percentage point of depreciation in the rupee, it said.

The ratings agency also identified the information technology and the pharmaceuticals as the sectors which benefit the most during a spate of currency depreciation, while consumer durables, fertilisers, chemicals, and automotive suppliers are among the sufferers.
"The lower sensitivity of these industry bellwethers can be attributed to their relatively large scale of on-shore operations, which causes them to incur significant foreign currency expenses as well," it said.
