Baiduri Bank is one of Brunei’s largest banks. Its exchange-rates page lists telegraphic-transfer and overdraft buying rates and a selling rate 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 Baiduri board shows

- **15 currencies against the Brunei dollar**: AED, AUD, CAD, CHF, CNY, EUR, GBP, HKD, IDR, JPY, NZD, PHP, SAR, 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**: Baiduri bought at 1.2767 and sold at 1.2984 BND, a spread of 1.69%.
- **The bank's own timestamp.** The page prints a last-updated stamp (`Nov 14, 2026, 8:45 AM` on the board above), returned as `bank_updated_at` next to our `captured_at`.
- **Every day's board is kept permanently, from 14 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 CHF (1.24%), USD (1.69%), GBP (3.17%) and the widest PHP (39.60%), IDR (36.17%), THB (10.80%). 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 Baiduri and other banks in Brunei

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

| Bank | Buy | Sell | Spread |
| --- | --- | --- | --- |
| **Baiduri Bank** | 1.2767 | 1.2984 | 1.69% |
| Bank Islam Brunei Darussalam (BIBD) | 1.277 | 1.299 | 1.71% |

Baiduri had the narrowest USD spread of the 2. One call to `/api/v1/bank-rates/bn` 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 full board:

```
curl "https://allratestoday.com/api/v1/bank-rates/bn/baiduri" \
  -H "Authorization: Bearer art_live_your_key"
```

What comes back (the 15 November 2026 board, first three rows):

## JavaScript

```
npm install @allratestoday/sdk

```
import { AllRatesToday } from '@allratestoday/sdk';

const client = new AllRatesToday({ apiKey: 'art_live_your_key' });

// Baiduri Bank's USD row
const r = await client.bankRates('bn', { bank: 'baiduri', ccy: 'USD' });
console.log(`Baiduri buys USD at ${r.buy}, sells at ${r.sell} BND`);

// The board as it stood on a past day
const past = await client.bankRates('bn', { bank: 'baiduri', date: '2026-11-14' });
console.log(past.snapshot_date, past.rates.length);
```

## Python

```
import requests

## 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. Baiduri'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](https://allratestoday.com/central-bank-rates-api/mas/) when a rule asks for the official rate.

## FAQ

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

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

### Are these the official BND exchange rates?

No. They are Baiduri'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 Baiduri 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 Baiduri rates for a past date?

Yes, from 14 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.
