Equity Stock Borrow/ Lend - key risks and features
Securities lending/borrowing is the act of loaning a stock or other security. Securities lending requires the borrower to put up collateral (102% or 105% of the securities value), whether cash, security or other. This is often maintained through a periodical mark-to-market based on the value of the underlying securities.
When a security is loaned, the title and the ownership are also transferred to the borrower. The borrower agrees to 'make good' the lender, as if the lender had never lent the securities. As payment for the loan, the parties negotiate a fee, quoted as an annualized percentage of the value of the loaned securities. If the agreed form of collateral is cash, then the fee may be quoted as a "rebate", meaning that the lender will earn all of the interest which accrues on the cash collateral, and will "rebate" an agreed rate of interest to the borrower.
