RE:Oh boy!!!!for clarity ?
Are they asking to borrow assets including stocks or just the cash?
If it is assets, then that practice has been going on for a long time which would include stocks so they can lend out to short and they inturn would charge the borrower more than 2%.
They would actually are borrowing your BBD stock giving you 2 % ..I presume you have a cash account and not margin because they would not have to ask to borrow your stock if margin.
The upside would be that stocks are needed to to close failed trades.
First time I have seen it called a promotion.
