Till March 8, the markets were under the impression that the defaults would be restricted to the unofficial badla market in Kolkata, where carry-forward charges had risen to the range of 150-300 per cent on KP’s favourites like hfcl and Zee. But the contagion had spread to the official market too. After each settlement, the carry-forward buyers have to pay up the difference between the price of the current settlement with the price of the previous settlement. If the price rises between settlements, the buyer gains, if it falls, he loses. Trouble is, the prices of KP’s shares have only been falling. Consider only the hfcl scrip. The brokers have failed to pay up the difference between settlement prices of Rs 819.60 and Rs 758.50. On March 16, they will have to pay up the difference between Rs 758.50 and Rs 388.60, more than six times what they failed to pay on March 8!
