How do I document an NBK rate for the date used in my file?

Select the supported NBK dataset and the date tied to the accounting, tax, audit, or compliance record. The signed PDF is available once that concrete proof bundle is ready.

Use the NBK page when accounting, tax, audit, or compliance teams need a repeatable proof document around Kazakhstan reference-rate evidence.

Is the signed PDF issued by the National Bank of Kazakhstan?

No. The National Bank of Kazakhstan publishes the underlying reference-rate data. FXProof issues and signs its own source-attributed document and is not affiliated with or endorsed by NBK.

  • National Bank of Kazakhstan source attribution.
  • Source date or reference date used for the rate.
  • Rate context for the selected dataset and date.
  • FXProof document id, payload hash, digital signature, and verification information.

What if I have already saved the NBK rate webpage?

The saved page can remain as source context. The FXProof PDF adds a stable record of the chosen dataset, date, and rate context, together with a digital signature and public verification details.

Place the signed PDF with the business record that used the rate. Recipient requirements and jurisdiction-specific rules still apply.

Questions

Can I get NBK proof for a historical date?

You can check the supported NBK dataset and date. The proof PDF is available only when the matching bundle is ready.

Does FXProof act on behalf of NBK?

No. NBK publishes the underlying rate data. FXProof independently issues the signed proof PDF and does not claim affiliation or endorsement.

What should stay with the Kazakhstan business record?

Attach the signed FXProof PDF to the record that used the rate. The source context, proof fields, signature, and verification details are inside the document.

Can a reviewer check the NBK-based proof without an account?

Yes. The reviewer can inspect the PDF, validate its signature, and use the displayed document id and payload hash on the public FXProof check page.

Keep the proof with the file that used the rate

Inspect a static sample first, then use an account when you need a proof bundle for a concrete dataset and date.
