Interactive Brokers Singapore (IBSG) holds a Capital Markets Services License (CMSL) from the Monetary Authority of Singapore (MAS). The MAS prescribes the type of collateral that IBSG is allowed to accept from its clients for product financing when using a Margin account at IBSG.
If any of the assets in your IBSG account no longer qualify as acceptable collateral for any reason, including but not limited to: exclusion from a major market index, a fall in shareholders' funds below SGD 200 million, or a credit rating downgrade, they will be automatically marked as non-marginable by our systems. The determination of collateral acceptability is done automatically by our systems, on a periodic basis.
When formerly-accepted collateral in your account is marked as non-marginable, your overall margin requirement will increase and your Excess Liquidity will fall.
For the current list of acceptable collateral prescribed by the MAS, please see Securities and Futures (Financial and Margin Requirements for Holders of Capital Markets Services Licenses) Regulations.
