Sell-side

Dealer-grade MBS throughput, without the dealer-grade ops floor.

Primary and regional fixed-income desks clear $1 billion to $180 billion a month on AFS — with higher automated throughput and meaningfully lower headcount than legacy processing.

The sell-side reality

Matching the market’s throughput shouldn’t mean matching it in people.

Sell-side MBS processing is still largely manual. Legacy approaches require two to three times the operations headcount to clear comparable volume. In the age of automation, that’s a structural disadvantage.

$1–180B

Monthly volume

Primary and regional dealer clients across the full volume range.

Cost and collateral

Two balances to carry, or one.

When a client offsets with a round robin, both dealers are left holding part of the difference until settlement date. When they assign, one dealer is closed out entirely and the other carries the whole net. Same economics, different exposure, different collateral.

Fewer open balances

An assignment takes one counterparty flat at the point it completes. Nothing left to mark, nothing to margin, nothing to reconcile at settlement.

Reported on time

SIFMA allows up to 12 hours for an assignment to reach the third dealer, and firms send when they process. Automated delivery means it arrives in seconds, not at the end of the window.

Fewer trades to book

Round robin legs are genuine market trades that land in your book and have to be processed. Assignment trades are booked at the original prices and are not new market exposure.
