If your business invoices, imports, or reports in a currency other than the CUP, sooner or later someone will ask which rate you used — and “the one on the internet that day” is not an answer that survives an audit. For that, you want the official number: Banco Central de Cuba’s published official reference rates.

## What are the Banco Central de Cuba official reference rates?

Banco Central de Cuba publishes the official peso rates daily for 13 currencies through its own public API, in three segments: the official rate for the state sector (Segment I, 24 pesos per dollar), the population rate (Segment II, 120 pesos) and the special rate introduced in December 2025 (Segment III), which the bank sets each day and which moved from 410 to 681 pesos per dollar in its first nine months. The API serves all three as rate types official, public and special, so a query never mixes them; our archive runs from 19 December 2025, the first day of the bank's published series.

It is published **once every business day**, currently covering **13 currencies**, and the published record runs back to **2025**. Crucially it is a *published* figure, not a live market price — it does not move after it is set, which is exactly the property an accountant or an auditor needs.

## Why finance teams need the official rate

### Book closing and month end

Foreign-currency balances have to be translated at a defensible rate on a specific date. Using a live market rate means the number changes depending on what minute you pulled it, and two people closing the same month can produce two different sets of books. The central bank’s published rate for that date is fixed and reproducible forever.

### FX gain and loss

Revaluing receivables and payables needs the rate at invoice date and the rate at settlement date. Both have to come from the same series, or the gain and loss you report is partly an artefact of switching data sources mid-stream.

### Audits and compliance

An auditor does not want a screenshot. They want a rate that traces back to a named publisher and a publication date they can independently check against Banco Central de Cuba’s own release. That is the entire reason official rates exist.

### Management reporting

Group reporting across entities only consolidates cleanly when every entity converts at the same published rate for the same date. Left to their own devices, subsidiaries will each pick a different source.

## The problem with collecting the rate by hand

Banco Central de Cuba publishes the data — but publishing and being easy to consume are different things. In practice teams end up copying figures off the bank’s rates page into a spreadsheet every morning, which creates four familiar problems:

- **It is manual, so it gets skipped.** Someone is on leave, a day gets missed, and the gap is only discovered at close.
- **Typos are invisible.** A transposed digit in a rate looks exactly like a correct rate until the variance shows up somewhere else entirely.
- **History is awkward.** Restating a prior period, or answering an auditor about a shipment from two years ago, means digging through archives rather than making one query.
- **Non-publication days trip people up.** Weekends and public holidays have no rate at all, and every team invents its own rule about what to use instead — usually without writing it down.

## The Banco Central de Cuba rates as an API

AllRatesToday ingests Banco Central de Cuba’s published table shortly after each release and serves it back in a consistent shape, alongside 123 other central banks and national tax authorities on identical endpoints.

- **Official figures, unmodified** — served with Banco Central de Cuba’s own publication date on every response.
- **13 currencies** against the CUP.
- **History back to 2025** — query any past date, or pull a full time series.
- **Honest holiday handling** — non-publication dates resolve to the most recent published table and say so, rather than silently interpolating.
- **Formats finance actually uses** — JSON, CSV, XML and genuine Excel workbooks, so it lands in a spreadsheet, Power BI or an ERP without a conversion step.
- **Published vs derived is labelled** — a pair Banco Central de Cuba did not print itself is computed from its table and flagged, never passed off as an official quote.

### Sample response

A real response for USD to CUP, from Banco Central de Cuba’s publication of 2026-09-26:

```
{
  "bank": "bccu",
  "rate_date": "2026-09-26",
  "source": "USD",
  "target": "CUP",
  "rate": 681,
  "rate_type": "special",
  "derived": false
}
```

The `rate_date` is the central bank’s own publication date — the date you cite in the ledger — and `derived` tells you whether Banco Central de Cuba printed this pair itself.

## Who this is for

- **Exporters and importers** converting invoices and customs values at a rate that has to hold up later.
- **Finance and accounting teams** closing books across currencies.
- **Auditors and advisors** who need to reproduce a client’s conversion months after the fact.
- **ERP, accounting and invoicing platforms** that need an official rate feed their own customers can defend.
- **Fintech and payments teams** that price on market rates but must *report* on official ones.

## What it actually saves

- **Time** — no one copies rates into a spreadsheet every morning again.
- **Accuracy** — the figure is whatever Banco Central de Cuba published, with no retyping in between.
- **Audit risk** — every number carries its publication date, so “where did this come from?” has an answer.
- **Consistency** — every entity, report and invoice converts from the same series.

## FAQ

### Where do Banco Central de Cuba exchange rates come from in this API?

Directly from Banco Central de Cuba's own published official reference rates. Rates are stored unmodified with the central bank's publication date attached, so the figure in your ledger is the figure Banco Central de Cuba printed, going back to 2025.

### Can I get the Banco Central de Cuba rate for a past date, like an invoice or shipment date?

Yes. Ask for any past date and you get the rate in force then, back to 2025. If the central bank did not publish that day — a weekend or a public holiday — the API returns the most recent published table and flags that it did, so your audit trail stays honest instead of silently guessing.

### Do I need a developer to use this?

Not necessarily. Every coverage page offers the latest published table as an Excel or CSV download, and finance teams commonly pull the API straight into Excel, Power BI or their ERP on a schedule. A developer helps if you want it wired into invoicing or your accounting system automatically.

## Final thought

Official rates are not a nicer version of market rates — they answer a different question. Market data tells you what a currency is worth right now. Banco Central de Cuba’s published table tells you what rate your books, your customs entries and your auditor are entitled to expect for a given date. Getting that second number automatically, with its publication date attached, removes an entire category of month-end argument.
