See it in practice

Real tasks this feature was built for, from the use-case library.

"The auditor wants an independent valuation of our swap"

Set up the swap once (amortising supported) and get a monthly mark-to-market, PV01 and a downloadable valuation report your auditor will accept.

"We're refinancing — what's the breakage on the existing swap?"

Load the existing swap to see its live mark-to-market and how breakage evolves over time, so you can negotiate the exit or time the refinancing yourself.

"I run a book of swaps — which payments settle this week, and are the amounts right?"

See every swap cashflow falling due in the next 48 hours across your whole book, with amounts confirmed the moment the floating rate fixes — so treasury can check the number and line up cash before it settles.
