I've been trading VIX futures on IB for several years now and since Brexit account migration my margins on VIX futures spreads increased a lot. From their IB support chat I understood that portfolio margin for IBCE (Interactive Brokers Central Europe) clients is gone, but their new risk/margins system should be similar to pre-Brexit portfolio margin, but it seems that IBCE VIX traders got screwed?
Currently I can short one April VIX future and my initial margin requirement is $20 702, which is high but might be justifiable. However, if I short one April future and buy one May future (as one instrument on CFE) my margin for this spread is $27 579! And this spread position is a lot less risky than naked short future position.
Could someone please help me to figure out whether my margin increase is connected to account migration from IBUK to IBCE or it is just their "regular" and temporary margin increase. Unfortunately, IBs customer support was unhelpful.
