Capital markets regulator Sebi on Wednesday proposed to enhance the threshold for the basic service demat account (BSDA) to Rs 10 lakh from the current Rs 2 lakh in a bid to boost the participation of retail investors in the securities market. A basic service demat account, or BSDA, is a more basic version of a regular demat account. The facility was introduced by Sebi in 2012 for reducing the burden of demat charges on investors with small portfolios. At present, an individual can hold debt securities worth up to Rs 2 lakh and other than debt securities worth up to Rs 2 lakh in a single demat account to be eligible for BSDA. In order to further boost participation in the securities market and to facilitate ease of doing investments, the facility of BDSA has been comprehensively reviewed, Sebi said in its consultation paper. The regulator proposed that the value of securities held in the demat account should not exceed Rs 10 lakh for debt and other than debt securities combined at
