Rolling settlement system replaced the badla system from July 2, 2001. On July 2, 2001, 215 scrips were brought under the riling systems, bringing the total to 414 scrips. By January 2, 2002 all scrips were brought under compulsory rolling mode. Internationally most developed countries follow a T+3 cycle and are aiming to move to a T+1 cycle (next day settlement) or a T+0 cycle where trades are settled on the day they are executed (same evening settlement). This is system of T+0 is prevalent in Switzerland and volumes are phenomenal when compared to the T+3 system. Indian stock markets moved to the T+3 system from April 2002, in line with the recommendations of the “Group of Thirty” which suggested it as minimum international standard.
The rolling settlement has many advantages. One, it reduces speculation and arbitrage in scrips as settlement occurs on a daily basis. Thus, there would be increase in delivery-based transactions reducing the speculation currently existing by way of carry forward of position in various scrips. Apart from this, shifting position from one stock exchange to another will reduce which, in turn will eliminate arbitrage opportunities in scrips. Two, it reduces pricing glitches and manipulation and explores a better price discovery process. With the rolling settlement in place, all open positions at the end of each day would come up for delivery thereby improving the quality of cash market transactions. Thus, price formation process on daily basis would be improved thereby resulting in improved price discovery process. Three, it reduces end of settlement period pressure as shares are delivered and cash is paid everyday instead of a week. Thus, the rolling settlement spreads the delivery and payment throughout the week. Four, it narrows the bid-ask spreads, reduces the settlement risk and eliminates the need to synchronize the settlement dates on NSE and BSE or for that matter across the exchange. And, of course, with the implementation of a rolling settlement system, investors will be benefited, as settlement will not take long and the prices an investor pays or receives will be closer to the market price. Securities and money will be transmutable.
