Bank Islam Brunei Darussalam (BIBD) Exchange Rate API: BND Buy and Sell Rates as JSON

BIBD is Brunei’s largest bank and operates under Islamic banking rules. Its rates page lists telegraphic-transfer, overdraft and cash-note rates in Brunei dollars. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Monetary Authority of Singapore official rate and with other banks in Brunei, and the calls that return them.

What the BIBD board shows

• 15 currencies against the Brunei dollar: AED, AUD, CAD, CHF, CNY, EUR, GBP, HKD, JPY, NOK, NZD, SAR, SEK, THB and USD. Every value is BND per 1 unit of the foreign currency.
• The telegraphic transfer pair. The Brunei dollar is exchanged at par with the Singapore dollar, so Brunei bank boards follow Singapore rates; banks print a telegraphic-transfer buy and a combined TT/overdraft sell, some currencies per 100 units. Brunei’s central bank publishes no machine-readable daily table, so no official rate is shown next to these rows; because of the currency board, the Singapore dollar row should sit at about 1.
• USD on 15 November 2026: BIBD bought at 1.277 and sold at 1.299 BND, a spread of 1.71%.
• The bank's own timestamp. The page prints a last-updated stamp (2026-11-13 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 (1.71%), CHF (2.08%), GBP (3.11%) and the widest NOK (26.12%), SEK (24.86%), THB (24.09%). 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 BIBD and other banks in Brunei

USD on the 2 boards AllRatesToday reads in Brunei, all captured on 15 November 2026:

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

Board rate or official rate?

The Monetary Authority of Singapore rate is the one tax, accounting and customs rules in Brunei name; nobody transacts at it. BIBD's board is the price a customer actually gets. Where the central bank has a rate for the same currency, the API returns it as official with vs_official_pct alongside; for Brunei that is the US dollar only. Use the Monetary Authority of Singapore endpoint when a rule asks for the official rate.

FAQ

Where do the Bank Islam Brunei Darussalam (BIBD) rates come from?

From the bank's own public rates page (https://www.bibd.com.bn/rates), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price BIBD shows, with the mid, the spread and the Monetary Authority of Singapore rate added.

Are these the official BND exchange rates?

No. They are BIBD's retail prices for customers. The official rate in Brunei is the Monetary Authority of Singapore 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 BIBD 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 BIBD 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.
