Currently, certificates of entitlement (COEs) for categories C and E are "transferable".
Why would anyone with a Category C or E COE in hand want to transfer it away? It cannot be for fun; there is money to be made.
So, in addition to the points raised by Mr Richard Chan Yong Huat ("Put COE bidding in hands of buyers, not dealers"; yesterday), we should also remove the transferability of COEs, as often, trading could be taking place.
