Settlements & collateral
Infrastructure for shorter settlement windows
Systems that move cash and assets as settlement windows shorten, and a collateral network for tokenised money market funds.
THE CHALLENGE
Shorter windows leave less time for manual work
The UK moves to T+1 for securities and T+2 for fund units in October 2027. Instructions, confirmations and cash movements have less time to wait for manual intervention.
WHAT WE BUILT
What we have built and are building
Rebuilt while the operation ran
In 2022 Calastone's settlements system was rebuilt live, connecting order aggregation, exceptions and payment tracking across banks.
SWIFT ISO 15022 and ISO 20022
Support for both message generations lets the system work across different eras of market infrastructure.
Collateral network, under way
The Calastone Collateral Network, built on the Canton Network since 2025, lets money market fund units be used as collateral.
They are authentic and always go above and beyond to deliver for us.

Questions about how we work
-
How do you manage the risk of switching systems?
We rebuilt Calastone's settlements system in 2022 while the operation kept running. The new service is built alongside the existing one. Parallel testing lets your teams check it against live workflows and resolve differences before the switch, reducing disruption at cutover.
-
Who owns the system?
You own the work produced for you, including the code and documentation. Ownership transfers in full once the agreed work is paid for.
-
What happens after launch?
Authentic can continue developing and maintaining the system, or prepare a handover with documentation and training.
