In a statement, the central bank said heightened volatility in capital markets in reaction to COVID-19 has imposed liquidity strains on mutual funds (MFs), which have intensified in the wake of redemption pressures related to closure of some debt MFs and potential contagious effects therefrom.
The stress is, however, confined to the high-risk debt MF segment at this stage and the larger industry remains liquid, it said.
"With a view to easing liquidity pressures on MFs, it has been decided to open a special liquidity facility for mutual funds of Rs 50,000 crore," it said.
Meanwhile, domestic stock exchanges were trading on a positive note with benchmark indices Sensex trading with 691.95 points up at 32,019.17.
