SGX-ST may impose any conditions it thinks fit on dealing or trading in a Designated Instrument. A condition applies from the date of declaration to all contracts of the Designated Instrument entered into on or after the date of declaration, or as indicated by SGX-ST. The conditions may include, but are not limited to, the following:

(a) a requirement that Trading Members obtain margins from each customer in respect of the customer's dealing or trading in the Designated Instrument;
(b) a restriction on dealing or trading in a Designated Instrument by a Trading Member if its outstanding contracts exceed 5% of the total issued shares or units of the relevant Issuer whose shares or units are designated or underlies the Designated Instrument, or any other percentage or benchmark that SGX-ST prescribes; or
(c) a prohibition on any sale unless the seller holds the Designated Instrument, or in the case of a Designated Instrument that is a futures contract, the underlying. A seller holds a security, futures contract, or underlying if, at the time of sale, he has the security, futures contract or underlying in an account maintained with CDP, or delivers the share certificates and executed transfer forms to the Trading Member.
