Application Supported by Blocked Amount (ASBA) is a facility where the investment application in a New Fund Offer (NFO) is accompanied by an authorization to the bank to block the amount of the application money in the investor's bank account.
The benefit of ASBA is that the money goes out of the investor's bank account only on allotment. Until then, it keeps earning interest for the investor.
