Short-term interest rates have surged and shares have slumped after the Reserve Bank of India unveiled measures late on Monday in an attempt to shore up the ailing rupee.
The temporary, three-day repo borrowing window for mutual funds will make up to 250 billion rupees available to asset management companies at 10.25 percent interest, according to a notification issued on Wednesday.
Further details will be provided at a later date, the Reserve bank of India (RBI) said.
"It seems like a pro-active move on part of RBI, which should help settle some nerves. This move would help mutual funds meet their redemptions and this would also help stabilise the yields in the market," said Ganti N. Murthy, head of fixed income at Peerless Fund Management Co. Ltd.

Liquid and money market funds had assets under management of 1.6 trillion rupees as of the end of June. Banks and companies tend to be the biggest investors in liquid and money market funds to manage excess cash.
"By last evening the situation was so bad that we felt mutual funds could face a payment crisis," said Taurus Mutual Fund chief executive, R.K. Gupta said.
"This gives us room to manage the outflows."
The RBI last provided a repo window to asset managers in the wake of the 2008 financial crisis.
