First National Bank Botswana Exchange Rate API: BWP Buy and Sell Rates as JSON

First National Bank Botswana is a FirstRand subsidiary and one of Botswana’s largest banks. Its forex page lists selling, telegraphic-transfer buying and note buying rates for remittances. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of Botswana official rate and with other banks in Botswana, and the calls that return them.

What the FNB Botswana board shows

• 15 currencies against the Botswanan pula: AUD, CAD, CHF, DKK, EUR, GBP, HKD, INR, JPY, NAD, NOK, NZD, SEK, USD and ZAR. Every value is BWP per 1 unit of the foreign currency.
• The telegraphic transfer (remittance) pair. The pula moves on a crawling peg against a basket of the rand and the SDR currencies; banks print most currencies as foreign units per pula, and the gap between buying and selling is wide, often more than 10%. The rates here are converted to pula per unit. The Bank of Botswana official rate is shown next to each row.
• USD on 15 November 2026: FNB Botswana bought at 13.1811 and sold at 14.8056 BWP, a spread of 11.61%. The Bank of Botswana official rate was 13.5685, so the bank's mid sat +3.13% from it.
• The bank's own timestamp. The page prints a last-updated stamp (2026-11-13 10:00:24 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 (11.61%), NAD (13.31%), ZAR (13.55%) and the widest INR (17.42%), JPY (15.34%), EUR (14.64%). 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.

Board rate or official rate?

The Bank of Botswana rate is the one tax, accounting and customs rules in Botswana name; nobody transacts at it. FNB Botswana'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 Botswana endpoint when a rule asks for the official rate.

FAQ

Where do the First National Bank Botswana rates come from?

From the bank's own public rates page (https://www.fnbbotswana.co.bw/Controller?nav=rates.forex.list.ForexRatesList), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price FNB Botswana shows, with the mid, the spread and the Bank of Botswana rate added.

Are these the official BWP exchange rates?

No. They are FNB Botswana's retail prices for customers. The official rate in Botswana is the Bank of Botswana 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 FNB Botswana 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 FNB Botswana 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.
