About Bangladesh Bank

Bangladesh Bank, the central bank of Bangladesh, publishes the Exchange Rate of Taka each business day: the highest and lowest interbank USD/BDT rates at the Dhaka close together with the weighted average rate of the day’s interbank deals, plus taka cross rates for ten more currencies. The rate is determined by interbank supply and demand rather than an administered fixing, and it is the reference Bangladeshi banks, importers and auditors convert at.

Node.js / TypeScript client

A dedicated zero-dependency npm package wraps these endpoints — bangladesh-bank-exchange-rate:

npm install bangladesh-bank-exchange-rate

import { getRate } from 'bangladesh-bank-exchange-rate';

const pair = await getRate('USD', 'BDT', { apiKey: 'art_live_...' });
console.log(pair.rate, pair.rate_date);

Zero dependencies, TypeScript types included, and it runs anywhere fetch exists — Node 18+, Bun, Deno, and edge runtimes.

Full reference — installation, all four functions, response shapes, error codes: bangladesh-bank-exchange-rate documentation.

Why use the official Bangladesh Bank rate?

Live market rates move continuously, but tax filings, customs declarations, audits, and statutory accounting in Bangladesh and beyond typically require the official rate published by Bangladesh Bank for a given date — a fixed, citable number that never changes after publication. This API serves those published tables with the bank's own rate_date on every response; weekends and holidays return the most recent published date, which is the rate compliance rules require you to apply.

Pairs the bank doesn't print directly are resolved from its table (inverse or cross via BDT) and explicitly flagged "derived": true — so what the bank printed and what was computed are never confused.

Endpoints

• GET /api/v1/central-bank/bb/latest — latest table or single pair (all plans)
• GET /api/v1/central-bank/bb/{YYYY-MM-DD} — the table for any date (paid plans)
• GET /api/v1/central-bank/bb/history — time series, up to 5,000 rows (paid plans)
• GET /api/v1/central-bank/bb/availability — publication calendar: the dates the bank actually published (all plans)

Full parameter reference in the API documentation. Every request counts toward your plan's monthly quota — rates change once per business day, so caching a published table locally makes a small quota go far.

Frequently asked questions

Can I get Bangladesh Bank exchange rates via an API?

When do new rates appear here?

Once per business day, per Bangladesh Bank's own schedule; ingestion follows within the hour (latest table: 2026-09-10).
