The new model, derived from the global best practices, follows four distinct steps -- assessing the risk posed by a market entity, assigning 'risk and impact rating' to it, determining supervisory risk rating score and then adopting a suitable supervisory approach.
Various market entities would be divided broadly into four groups -- very low risk, low risk, medium risk and high risk -- and the quantum of surveillance and number of inspections would increase as per the risk level.
The move would help the existing surveillance system take care of most of the smaller offences, so that the investigation resources are utilised more effectively to tackle serious violations in the market place.
Under the new model, members have to provide various details including those about the branches, sub- brokers and associated persons, as also information about their inspections and facilities like voice recording available there.
The details of clients categorised as high-risk clients, such as Politically Exposed Persons, clients from countries facing global sanctions and NRIs etc also need to be given.
