Dollar Roll

Definition of 'Dollar Roll'


A type of repurchase transaction in the mortgage pass-through securities market in which the buy side trade counterparty of a "to be announced" (TBA) trade agrees to a sell off the same TBA trade in the current month and to a buy back the same trade in a future month at a lower price.

In a dollar roll, the buy side trade counterparty gets to invest the funds that otherwise would have been required to settle the buy trade in the current month until the agreed upon future buy-back. The sell side trade counterparty benefits by not having to deliver the pass-through securities (which they might otherwise have shorted or committed to another trade) in the current month.

Investopedia explains 'Dollar Roll'


The price difference between months is known as the drop. When the drop becomes very large, the dollar roll is said to be "on special". This might happen for several reasons, including large collateralized mortgage obligation deals that increase the demand for mortgage pass-through securities, or unexpected fallout of mortgage closings in a mortgage originator's pipeline. In both cases, financial institutions might have more sell trades in the current month than they are able to deliver securities into, forcing them to "roll" those trades into a future month. The greater the shortage of available securities in the current month, the larger the drop becomes.
