# Real-Time Repo Sweeps

> Moving excess balances into and out of repurchase agreements without waiting for a settlement window.

A sweep moves excess balances out of an operating account and into an
interest-bearing instrument, commonly an overnight repurchase agreement. It
returns those balances when they are needed.

The economics are simple: idle balances earn nothing, while swept balances earn
the repo rate. Timing limits the value captured.

## Why timing is the constraint

Conventional sweeps run on a schedule set by settlement windows, not when the
balance is actually idle.

A balance that arrives after the cutoff waits until the next cycle. A balance
needed before the return leg settles cannot be swept at all. The bank therefore
holds a buffer sized for the gap between when funds move and when they can move
back, and that buffer is the cost of the settlement window.

## What changes with tokenized deposits

A tokenized deposit is the cash leg recorded on a digital ledger, so sweeps can
run when the balance is idle and unwind when it is needed.

This means the buffer shrinks toward the amount actually required for operations,
not the amount required to survive until the next settlement cycle.

Delivery versus payment is joint settlement of the cash and instrument legs, so
neither completes alone. See
[Atomic Settlement](/settlement/atomic-settlement) and
[Delivery vs Payment](/settlement/delivery-vs-payment).

<Note>
  Real-time repo sweeps have been demonstrated but are not documented here as a
  shipped configuration. The instruments supported, how sweep policy is authored
  and approved, and the counterparty arrangements required all still need to be
  documented. Contact [sales@cosmoslabs.io](mailto:sales@cosmoslabs.io) to discuss a repo use case.
