So, today I have logged in to IBKR to do buy some ETFs which I do on a monthly basis and I have found that IBKR automatically liquidated one share of the ETF in which I invest:
This is to inform you that Interactive Brokers liquidated certain positions in your account XXXXXX because a negative cash position is not allowed in this specific account type. Such an account type becomes subject to liquidation upon going negative cash.
I have a cash account (no margin) in CHF. So, I went to see how come I ended up with negative amount and I saw that it was due to the fact that on that day when IBKR did automatic liquidation, they settled interest accruals from the previous months which ended up being negative. When I run cash statement, I see that the negative interest came from
CHF Credit Interest (CHF Credit Interest for Nov-2021) which exceeded what I had in CHF on that day (I had less than a franc, though I also had several dollars in USD, but apparently since the account is in CHF the USD balance didn’t count).
What’s this CHF Credit interest and how come it can be negative? When I made CHF deposits to my IBKR account I have never exceeded 100k, so it shouldn’t be because I exceeded the 100k limit for CHF cash.
