Capital Bank is a Haitian commercial bank based in Port-au-Prince. Its home page lists dated branch and online buying and selling prices for the US dollar in gourdes, by amount. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Banque de la République d’Haïti official rate and with other banks in Haiti, and the calls that return them.

## What the Capital Bank board shows

- **1 currency against the Haitian gourde**: USD. Every value is HTG per 1 unit of the foreign currency.
- **The branch buy / sell, smallest USD tranche pair.** Haitian banks quote gourdes per US dollar by amount tranche, with separate branch and online prices. The Banque de la République d’Haïti publishes a daily reference rate. The Banque de la République d’Haïti official rate is shown next to each row.
- **USD on 15 November 2026**: Capital Bank bought at 129.5 and sold at 132 HTG, a spread of 1.91%. The Banque de la République d’Haïti official rate was 131.73, so the bank's mid sat -0.74% from it.
- **The bank's own timestamp.** The page prints a last-updated stamp (`14 NOVEMBRE 2026` on the board above), returned as `bank_updated_at` next to our `captured_at`.
- **Every day's board is kept permanently, from 14 November 2026.** Read one past day with `?date=`, or a range for one currency with the `/history` endpoint (paid plans).

## Spreads across the board

On the 15 November 2026 board the spread was USD 1.91%. Spread is (sell − buy) ÷ mid: what a round trip through the bank costs, before any fees. The API returns it on every row as `spread_pct`, so you can rank currencies or alert when a bank widens its board.

## USD at Capital Bank and other banks in Haiti

USD on the 3 boards AllRatesToday reads in Haiti, all captured on 15 November 2026 (the Banque de la République d’Haïti official rate was 131.73):

| Bank | Buy | Sell | Spread | Mid vs official |
| --- | --- | --- | --- | --- |
| Sogebank | 129.5 | 132 | 1.91% | -0.74% |
| Banque Nationale de Crédit (BNC Haïti) | 129.25 | 131.75 | 1.92% | -0.93% |
| **Capital Bank Haïti** | 129.5 | 132 | 1.91% | -0.74% |

Capital Bank had the 2nd narrowest USD spread of the 3. One call to `/api/v1/bank-rates/ht` returns every board in the table at once.

```

## Board rate or official rate?

The Banque de la République d’Haïti rate is the one tax, accounting and customs rules in Haiti name; nobody transacts at it. Capital Bank's board is the price a customer actually gets. The API puts both on every row: `official` is the central bank's rate for the same currency and `vs_official_pct` is how far the bank's mid sits from it. Use the board to show customers a real price, compare banks for a remittance, or keep a dated record of what the bank quoted; use the [Banque de la République d’Haïti endpoint](https://allratestoday.com/central-bank-rates-api/brh/) when a rule asks for the official rate.

## FAQ

### Where do the Capital Bank Haïti rates come from?

From the bank's own public rates page (https://www.capitalbankhaiti.biz/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Capital Bank shows, with the mid, the spread and the Banque de la République d’Haïti rate added.

### Are these the official HTG exchange rates?

No. They are Capital Bank's retail prices for customers. The official rate in Haiti is the Banque de la République d’Haïti rate, which the API returns as `official` on each row where the central bank has one, and in full from the central-bank endpoint.

### How often is the Capital Bank board updated?

AllRatesToday reads the page every hour. The bank's own last-updated stamp is returned as `bank_updated_at`, so you can tell a fresh read of an unchanged board from a new board.

### Can I get Capital Bank rates for a past date?

Yes, from 14 November 2026 onward; every day's board is kept permanently. Add `?date=YYYY-MM-DD` for one day: the response is the board captured that day, or the nearest earlier day within five days, with `date_requested` and `snapshot_date` added. For a range, `/history?ccy=USD&from=…&to=…` returns one row per day as JSON, CSV, XML or XLSX on paid plans.

### Do I need an API key?

Yes. Commercial bank boards need an API key; any plan works, the free key included, and each call counts against the plan. Public pages or widgets that show the rates need a visible link to allratestoday.com.
