The problem

You receive marks you can't check

Three moments where not having an independent curve costs you money, credibility, or sleep.

Monday 9am

The margin call you can't explain

Your prime broker: "Wire $380K variation margin by 2pm." Your internal number says $340K. $40K gap. Who's right? You don't have the tools to check. You wire $380K and hope.

With CheckMySwap: pull yesterday's curve vs today's. Reprice your book. Your number: $378,200. Broker was right. You pay with confidence — not on faith.
Quarter-end

The audit question you dread

"How did you independently verify the fair value of your $200M swap portfolio?" You show PwC the bank's statement. They want YOUR valuation. You don't have one.

With CheckMySwap: hand the auditor a report. Each swap repriced against the public OIS curve. Full audit trail. Every discount factor reproducible.
Board meeting

The question you can't answer

"What happens to our hedges if rates rise 100bp?" Your treasurer looks at last month's bank report. It's stale. The board wants a number. Now.

With CheckMySwap: stress your book live. +100bp → -$2.1M. Steepener → -$890K. Real-time. Not last month's snapshot.
How it works

Three steps. Thirty seconds.

01

We publish the curves

Every business day. USD SOFR, EUR ESTR, GBP SONIA, JPY TONA, CAD CORRA — derived from actual interbank swap trades reported to the DTCC. Published via API. Archived permanently.

02

You reprice your trades

Send swap terms to our API — or use the web pricer. We return PV, DV01, stress P&L. Same math as your bank.

03

You compare

Your number vs the bank's number. Match → confirmed. Differ → you have a question to ask. Either way, you know.
