REST, JavaScript and Python examples." canonical: https://allratestoday.com/blog/banco-comercial-do-huambo-exchange-rate-api/ source: AllRatesToday (https://allratestoday.com/) — Markdown mirror of the page above; index of all pages at https://allratestoday.com/llms.txt generated: 2026-11-15T19:12:12.812Z --- Banco Comercial do Huambo (BCH) is an Angolan commercial bank headquartered in Luanda. Its home page lists buy and sell rates in kwanzas for six currencies. This guide shows how to read that board as JSON: what the rates mean, how they compare with the National Bank of Angola official rate and with other banks in Angola, and the calls that return them. ## What the BCH board shows - **6 currencies against the Angolan kwanza**: BRL, EUR, GBP, NAD, USD and ZAR. Every value is AOA per 1 unit of the foreign currency. - **The exchange board (compra / venda) pair.** Angolan banks quote the kwanza with separate divisas (transfer) and notas (bank-note) columns, often at the same price. On 2026-11-13 the BAI dollar mid sat about 5% above the market rate. The National Bank of Angola official rate is shown next to each row. - **USD on 15 November 2026**: BCH bought at 909.05 and sold at 926.32 AOA, a spread of 1.88%. The National Bank of Angola official rate was 913, so the bank's mid sat +0.51% from it. - **No timestamp on the bank's page.** BCH 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 USD (1.88%), BRL (2.76%), EUR (2.76%) and the widest ZAR (2.76%), NAD (2.76%), GBP (2.76%). 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 BCH and other banks in Angola USD on the 6 boards AllRatesToday reads in Angola, all captured on 15 November 2026 (the National Bank of Angola official rate was 913): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | Banco BAI | 966.57 | 985.9 | 1.98% | +6.93% | | Banco Económico | 911.17 | 931.26 | 2.18% | +0.90% | | Banco Sol | 913 | 1049.95 | 13.95% | +7.50% | | **Banco Comercial do Huambo** | 909.05 | 926.32 | 1.88% | +0.51% | | Banco BIC | 913 | 949.52 | 3.92% | +2.00% | | Banco Yetu | 931.26 | 1035.8 | 10.63% | +7.72% | BCH had the narrowest USD spread of the 6. One call to `/api/v1/bank-rates/ao` returns every board in the table at once. ## Get the board (REST) You need an API key; the [free key](https://allratestoday.com/register/) works.

The National Bank of Angola rate is the one tax, accounting and customs rules in Angola name; nobody transacts at it. BCH'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 [National Bank of Angola endpoint](https://allratestoday.com/central-bank-rates-api/bna/) when a rule asks for the official rate. ## FAQ ### Where do the Banco Comercial do Huambo rates come from? From the bank's own public rates page (https://www.bch.co.ao/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price BCH shows, with the mid, the spread and the National Bank of Angola rate added. ### Are these the official AOA exchange rates? No. They are BCH's retail prices for customers. The official rate in Angola is the National Bank of Angola 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 BCH 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 BCH 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. ## Banco Comercial do Huambo rates, as JSON Free API key, hourly board captures, the official rate alongside.
