My Portfolio is as follows, I have a NAV of around 1.2Mil and IB initial margin of 1.127Mil. So my NAV is around 106% of my NAV. My excess liquidity is 150k and available funds are 71k. The market value of all my securities is around 3 Mil and I have short options covering pretty much all my long with a value of 1.4Mil I then currently have a open margin loan with IB of around 425k. For the lasts couple months not a single stock in my 3Mil in positions has been lent out. I even hold stock in positions that have a short utilization of well over 50%. I keep on getting told by IB CS chat that it is because there is no interest, but I find that very hard to believe. I saw on the FAQ the following, Excess margin securities are securities that have not been completely paid for, but whose market value exceeds 140% of the customer’s margin debit balance. I wonder if the lack of lending is related to this. I have tried to ask CS chat but I don't think they are understanding what I am asking. Does anyone have any experience with my situation?
