Changes to Initial Futures Margins and the Restriction of Certain Options for Retail Clients Resident in Spain
Overview
IBIE determines risk-based maintenance margins, which are either equivalent to or higher than the exchange requirements, depending on our risk view. A violation of maintenance margin necessitates a liquidation.
Due to Spanish regulatory requirements, IBIE applies specific initial margin rates for retail clients resident in Spain (“Spanish Retail Clients”) as well as restricting certain option strategies. These measures do not apply to Spanish professional clients.
Initial Futures Margins for Spanish Retail Clients
IBKR typically sets initial margin at 125% of the maintenance margin. However, Spanish regulatory requirements prohibit liquidations of futures before 50% of the posted initial margin has been consumed by losses. The initial margin for Spanish Retail Clients will therefore be 200% of the maintenance margin. This will also be the case for a futures position that is combined with futures options on the same future or options on the same underlying, as IBIE margins derivatives positions referencing the same underlying asset as a unit.
Moreover, IBIE does not provide intra-day margin reductions for Spanish Retail Clients, as these are not allowed under Spanish regulations.
Note that margins for options and futures options are otherwise unaffected.
Restriction of Certain Options for Spanish Retail Clients
Spanish Retail Clients are not allowed to take “naked” short option positions with potentially unlimited losses (i.e., selling a call without a corresponding position in the underlying or option combos where the long leg expires first). This restriction is to avoid excessively high initial margin requirements.
Impact of the Changes
This increased Initial Margin Requirement will not impact your overnight Maintenance Margin Requirement. However, any increase in the Initial Margin requirement may adversely affect your ability to open new margin-increasing positions and withdraw funds. You may wish to review and/or adjust your positions or add more funds to your account to address the increased Initial Margin Requirements.
