The CAD, which is the difference between inflow and outflow of foreign currency, "widened from 5.4 per cent in Q2 (July-September) to a record high of 6.7 per cent of GDP in Q3, driven mainly by large trade deficit" RBI said in its report on Balance of Payments.
The report said while the merchandise exports did not show any significant growth during the third quarter ending December 2012, the imports shot up by 9.4 per cent, spurred largely by oil and gold imports.
Finance Minister P Chidambaram in his Budget speech had said: "my greater worry is the CAD". He attributed the rise in the CAD to factors like excessive dependence on oil imports, the high volume of coal imports, passion for gold and slowdown in exports.
During April-December 2012, CAD stood at USD 71.7 billion accounting for 5.4 per cent of GDP as against USD 56.5 billion (4.1 per cent of GDP) in the same period of 2011.
The central bank said the surge in capital inflows, mainly on account of portfolio investment, would help in financing the higher CAD.
The FII inflow during the quarter rose to USD 8.6 billion from USD 1.8 billion a year ago.
