Repo

The Repo Market: GC, Specials, Haircuts, and Rehypothecation

Book: Fixed Income Trading and Risk Management by Alexander Düring (ISBN 9781119756354)

Chapter 14 is about repo, and repo is the engine under almost everything in fixed income trading. A repurchase agreement is a sale plus a promise to buy back the same security later. Cash goes one way, collateral the other. Economically it’s a secured loan. The repo rate is the interest on the cash leg.
