Anyone have any thoughts on the impacts of Brexit on IBKR?
Swiss Franc Debacle: Although there were wild swings last night, they weren't as dramatic as the Swiss Franc. I think it also unlikely that people were positioned heavily in anticipation of a REMAIN vote. The increased margin rates seem sufficient.
Interest rates: Not a major factor. The increase in the 2 year should result in mark-to-market losses, but probably lead to slightly lower NIM? IBKR is not as interest rate sensitive as Schwab.
Currency: GLOBALS currency basket will take a big hit.
Volatility: increased volatility should be good for market maker and commissions.
Altogether, I don't think these add up to a significant impact.
