The new estimate compares with projections of 5.7 per cent made in June and 7 per cent in September 2012, underlining the "severity of the growth shock," the rating agency said in its 'Global Economic Outlook' report released on Thursday.
Fitch said prospects of a swift economic turnaround have been further dented by a 20 per cent fall in the domestic currency since the end of May due to increased concerns over the country's large current account deficit.
"Demand is weak, both externally and domestically, which is a large drag on the economy," the agency said
Fitch also cut India's growth rate projection for FY'15 to 5.8 per cent from the June forecast of 6.5 per cent. In September 2012, the company had projected a growth of 7.5 per cent for FY'15.
