"Offshore appetite for government bonds is likely to stay strong with the gradual relaxation of the FII debt limits to be announced every quarter," it said in a note.
Attractive bond yields, lower inflation outlook and relatively resilient rupee amidst the ongoing emerging markets currency weakness are among the other factors which are a draw for the investors, it added.
The report said offshore investors pumped in USD 1 billion into the G-secs during the first week of the year, despite volatility in the emerging markets.
Last September, the Reserve Bank had hiked the limits for FII investment in G-secs to 5 per cent of the outstanding stock by March 2018, a move that will bring in an additional Rs 1.2 trillion into this highly sought-after market segment.
Announcing the hike, Governor Raghuram Rajan had said the limits for FII investments in debt securities would henceforth be announced/fixed in rupee terms.
