Free counterparty audit

How much have your banks really charged you?

Upload up to 5 years of FX trades. Treasurii benchmarks each one against the mid-market rate at the moment you dealt, and shows you, trade by trade, the spread each counterparty took. Then it ranks them, worst to best.

The problem

Your spread is invisible by design.

Every bank builds a margin into the rate they quote you. You never see it as a line item, so you can't compare it, question it, or manage it. Over a year of trading, that invisible cost is anything but small.

Your bank quotes one all-in rate. The margin over the mid-market rate is baked into it, never itemised and never on the confirmation.
Across hundreds of trades and several counterparties, small spreads compound into real money you've never been able to see.
With nothing to benchmark against, "is this a good rate?" is a question you can't actually answer, so you don't ask.

What you get back

Your trades, benchmarked to mid-market. Your counterparties, ranked.

How it works

Three steps. Your numbers.

  1. 1

    Start the free audit, upload your trades

    The audit runs on a 14-day Lite trial: the full system-of-record tier, free while you run it. Upload up to 5 years of FX trades from a CSV export of your deal history. Nothing leaves your account.

  2. 2

    Every trade benchmarked to the mid-market rate

    Each trade is measured against the independent mid-market rate at the moment you dealt, the same benchmark Treasurii runs the whole platform on.

  3. 3

    Get your audit

    Ranked counterparties, total spread, and every trade on the chart, ready to export and take to your next rate conversation.

One benchmark. No agenda.

We don't sell you FX. We measure it.

Every trade is scored against the independent mid-market rate, not our rate or one we'd rather you saw. Treasurii isn't your counterparty, so the audit has no incentive to flatter anyone. Your data stays yours: private, immutable, never shared.

And when you're ready to stop leaking spread, the platform books every future trade against the very same benchmark. That turns the audit from a one-off into the last time your spread has to be a mystery.

  • Independent mid-market benchmark on every trade
  • Treasurii is not your counterparty, so no conflict
  • Your trade data is private, immutable and never shared
  • Export your report and take it to your bank
