ASBA stands for Application Supported by Blocked Amount, a procedure utilized for submitting applications for Initial Public Offerings (IPOs) or Follow-on Public Offerings (FPOs) in India. In this process, investors' application funds are retained in their bank accounts but are temporarily blocked until the shares are allocated. After the shares are assigned, the blocked amount is debited from the investor's account, and the remaining amount is released. Investors may submit their ASBA applications to Self Certified Syndicate Banks (SCSB).
