The move comes after RBS failed to close a deal involving sale of its India retail assets to Hongkong and Shanghai Banking Corporation.
The deal was called off in November last year.
"Discussions are on. It is still at an early stage and nothing has been finalised so far," a senior banker said, requesting not to be named.
In India, RBS has 31 branches that it got when a three-bank consortium, of which it was a part, acquired Dutch bank ABN Amro in 2007.
It was the largest acquisition in the global financial sector at then.
The value of the retail and commercial banking assets of RBS in India was estimated at around $1.8 billion at the end of March 2010.
"The valuation will depend on the quality of assets.
"It is premature to discuss it now," another banker said, confirming YES Bank's interest in RBS' retail assets in the country.
The move is in line with YES Bank's strategy to expand its retail banking business aggressively.
The bank recently roped in Pralay Mondal from HDFC Bank to oversee its retail banking operations.
