Centenary Bank is Uganda’s largest bank by customer numbers, founded by the Catholic Church in 1983. Its home page lists buying and selling rates in Ugandan shillings; the US dollar, pound, euro and rand are shown here. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of Uganda official rate and with other banks in Uganda, and the calls that return them.

## What the Centenary Bank board shows

- **4 currencies against the Ugandan shilling**: EUR, GBP, USD and ZAR. Every value is UGX per 1 unit of the foreign currency.
- **The exchange rates (buy / sell) pair.** Ugandan bank boards carry wide spreads on the shilling: on 2026-11-13 Centenary Bank bought dollars about 1% below the Bank of Uganda rate and sold them about 10% above it. Regional currencies (KES, TZS, RWF) carry even wider margins. The Bank of Uganda official rate is shown next to each row.
- **USD on 15 November 2026**: Centenary Bank bought at 3964.36 and sold at 4417.8 UGX, a spread of 10.82%. The Bank of Uganda official rate was 4119.43, so the bank's mid sat +1.74% from it.
- **No timestamp on the bank's page.** Centenary Bank does not print a last-updated time, so `bank_updated_at` is `null` and `captured_at` (when AllRatesToday read the page) is the only time available.
- **Every day's board is kept permanently, from 15 November 2026, the day collection started.** 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 GBP (7.43%), EUR (8.77%), USD (10.82%) and the widest ZAR (19.23%), USD (10.82%), EUR (8.77%). 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 Centenary Bank and other banks in Uganda

USD on the 4 boards AllRatesToday reads in Uganda, all captured on 15 November 2026 (the Bank of Uganda official rate was 4119.43):

| Bank | Buy | Sell | Spread | Mid vs official |
| --- | --- | --- | --- | --- |
| **Centenary Bank** | 3964.36 | 4417.8 | 10.82% | +1.74% |
| Bank of Baroda (Uganda) | 4155 | 4270 | 2.73% | +2.26% |
| Finance Trust Bank | 3913 | 4163 | 6.19% | -1.98% |
| Pride Bank | 4050 | 4200 | 3.64% | +0.14% |

Centenary Bank had the 4th narrowest USD spread of the 4. One call to `/api/v1/bank-rates/ug` returns every board in the table at once.

## Board rate or official rate?

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

## FAQ

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

From the bank's own public rates page (https://www.centenarybank.co.ug/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Centenary Bank shows, with the mid, the spread and the Bank of Uganda rate added.

### Are these the official UGX exchange rates?

No. They are Centenary Bank's retail prices for customers. The official rate in Uganda is the Bank of Uganda 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 Centenary Bank board updated?

AllRatesToday reads the page every hour. The bank prints no timestamp, so `captured_at` tells you when the rates were read.

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

Yes, from 15 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.
