However, as a percentage of the Gross Domestic Product (GDP), the country's external debt works out to be 23.8 per cent at the end of March 2015, up from 23.6 per cent as on March 2014.
"The rise in external debt was due to the rise in long-term debt particularly commercial borrowings and NRI deposits," Finance Ministry said in a statement.
The long-term debt at the end of March was USD 391.1 billion, reflecting an increase of 10.3 per cent over the March 2014 level.
The short-term external debt was USD 84.7 billion in March, showing a decline of 7.6 per cent over USD 91.7 billion at the end of March 2014.
Short-term debt, the release said, accounted for 17.8 per cent of the total external debt at the end of March, 2015 as against 20.5 per cent at March 2014.
The shares of government (sovereign) debt in the total external debt were 18.9 per cent at the end of March 2015.
External Commercial Borrowings (ECB) are a significant component in India's external debt and the key driver of its magnitude, it said.
"The rise in commercial borrowings was due to spike in commercial bank loans and securitised borrowing. ECB has always been occupying the highest share in India's external debt over the years. As at end-March 2015, ECB has the highest share of 38.2 per cent in India's external debt," it added.
