GCB Bank, formerly Ghana Commercial Bank, is Ghana’s largest bank by branch network and is majority state-owned. Its homepage lists buying and selling rates against the cedi for seven currencies, including the West African CFA franc, with an as-at date. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of Ghana official rate and with other banks in Ghana, and the calls that return them.

## What the GCB board shows

- **7 currencies against the Ghanaian cedi**: CAD, CNY, EUR, GBP, JPY, USD and XOF. Every value is GHS per 1 unit of the foreign currency.
- **The indicative forex board buy / sell pair.** The Ghana cedi floats and banks publish their own indicative buying and selling rates in cedis per 1 unit of the foreign currency, usually for a short list of major currencies. The Bank of Ghana publishes a daily interbank reference rate, which banks are not bound to use. The Bank of Ghana official rate is shown next to each row.
- **USD on 15 November 2026**: GCB bought at 11.55 and sold at 11.78 GHS, a spread of 1.97%. The Bank of Ghana official rate was 11.6958, so the bank's mid sat -0.26% from it.
- **The bank's own timestamp.** The page prints a last-updated stamp (`13th Nov. 2026` on the board above), returned as `bank_updated_at` next to our `captured_at`.
- **Every day's board is kept permanently, from 13 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 tightest spreads were USD (1.97%), GBP (2.52%), EUR (2.86%) and the widest XOF (27.27%), JPY (20.69%), CNY (8.45%). 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 GCB and other banks in Ghana

USD on the 11 boards AllRatesToday reads in Ghana, all captured on 15 November 2026 (the Bank of Ghana official rate was 11.6958):

| First National Bank Ghana | 11.6 | 11.8 | 1.71% | +0.04% |
| Consolidated Bank Ghana | 11.5 | 11.79 | 2.49% | -0.43% |

| Stanbic Bank Ghana | 11.52 | 11.8 | 2.40% | -0.31% |

GCB had the 2nd narrowest USD spread of the 11. One call to `/api/v1/bank-rates/gh` returns every board in the table at once.

## Board rate or official rate?

The Bank of Ghana rate is the one tax, accounting and customs rules in Ghana name; nobody transacts at it. GCB'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 [Bank of Ghana endpoint](https://allratestoday.com/central-bank-rates-api/bog/) when a rule asks for the official rate.

## FAQ

### Where do the GCB Bank rates come from?

From the bank's own public rates page (https://www.gcbbank.com.gh/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price GCB shows, with the mid, the spread and the Bank of Ghana rate added.

### Are these the official GHS exchange rates?

No. They are GCB's retail prices for customers. The official rate in Ghana is the Bank of Ghana 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 GCB 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 GCB rates for a past date?

Yes, from 13 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.
