Withdrawal of general permission to Overseas Corporate Bodies alters OCB authorisation, requiring conforming transactions under the revised regulatory framework. Withdrawal of general permission to Overseas Corporate Bodies (OCBs) is effected by the regulator under statutory foreign exchange powers; the regulation rescinds blanket authorization for OCBs and takes effect upon publication in the official gazette, requiring future authorisations or transactions by such entities to conform to the changed regulatory framework and any conditions the authority may specify.
