To achieve leverage in long positions, a bank can use the following strategy:
I. Securities may be purchased with borrowed funds using a bank loan from the broker.
II. Securities may be borrowed on margin by taking a loan from a broker.
III. Securities may be purchased and used in a repo transaction to generate cash for further security purchases.
IV. The bank may enter into a derivative transaction, such as a total return swap, that requires little to no collateral but mimics the performance of a long or short position in the underlying instrument.
