SEBI chairperson Madhabi Puri Buch said the capital markets regulator is "compelled" to warn against speculative bets in the futures and options (F&O) segment because it has become a "macro issue". Speaking at an event organised by SBI Mutual Fund, the regulator said the shift from savings to “speculative” activity was affecting the broader economy now. Household financial savings are going into the speculative bets, belying the expectations of being used for capital formation and the youth is losing tonnes of money in such trades, Buch said. “We felt compelled," Buch said, to proactively dissuade investors from the F&O segment.
