Securities and Exchange Board of India chairman CB Bhave has said that the biggest challenge before regulators across the globe is in handling large corporate entities given their persuasive abilities.

"Big entities have big persuasive ability ...their political and media access is tremendous and, therefore, regulators are going to be at the receiving end when they try and do something about these big entities," he said referring to the challenges before financial regulators globally.

Mr Bhave said global supervisors will have to assess whether they need to impose major obligations on these bigger entities taking into account the fact that they are too big to fail.

The Sebi chief conceded that regulators are yet to find an answer. According to him, large groups create a mess if they fail and the challenge for regulators is to handle the tremendous ability of such groups to work around regulation. "We need to handle this and it will be interesting to see how this gets handled in the days to come," he said.
