A repo transaction is a transaction in which an asset – typically a security – is sold on one date and then repurchased at a predetermined later date.
A repurchase agreement is an agreement in which the seller of a security agrees to repurchase the security on a specific future date.
A reverse purchase agreement is an agreement in which the buyer of a security agrees to sell the security back to the seller on a specific future date.
