Because the people who get payed to lend out their stock or contracts, have to own it, ie they can't do it if they hold the security on the margin side of their account. When people short a security, they use margin, so IB which charges about 3% gets to bag the difference (3% - 1.08%) + .25%.And I look at SPY. It says the fee rate is .25%, I take it annually. But the rebate rate is 1.08%? Does that mean one would get 1.08% to let someone short their stock, but the person that shorts it would only have to pay .25% annually? That really does not make sense to me...
I like their futures margins. I don't want IB to go bankrupt because of client accounts.
On the futures side we DO MUCH Better....Been with IB for probably not much short of 2 decades. Originally loved them for their super low commissions. But other brokers' commissions seemed to have dropped over time, and I do not know how much of an advantage IB has in that area these days. Bit their margin rates still seem KILLER compared to everyone else I see. Can anyone compete with them? If not, how can IB beat everyone else so soundly?
Why not straight forward US equities then?On the futures side we DO MUCH Better....
Some of you are talking about the margin required to trade equities/options or futures/options and some are talking about credit/debit interest rate spreads.
