Crowdfunding refers to financing of projects with small amounts of money raised from a large number of people, with a portal serving as an intermediary. It utilises an online platform which serves as a link between borrowers and lenders.
RBI vide a Notification on 24th August, 2017, enabled P2P entities as Non-Banking Financial Company (NBFC). However, an existing NBFC will not be able to operate as an NBFC-P2P.
Minimum networth requirement for these platforms is kept at Rs. 2 Cr. The borrower can either be an individual or a legal person (say a body of individuals, a HUF, a firm, a society or any artificial body, whether incorporated or not) requiring a loan.
The interest rate is not to be fixed by the platform. The interest rate for each and every loan is to be fixed separately over the electronic platform by way of a mutual agreement between the borrower and lender. Fund transfer between participants on the P2P lending platform will happen through escrow account mechanisms. All fund transfers shall be through and from bank accounts, and cash transactions are strictly prohibited.
