RHB Bank Exchange Rate API: MYR Buy and Sell Rates as JSON

RHB Bank is a Malaysian banking group headquartered in Kuala Lumpur. Its treasury rates page lists TT and bank-note buying and selling rates against the ringgit for more than 30 currencies, with an update time. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank Negara Malaysia official rate and with other banks in Malaysia, and the calls that return them.

What the RHB board shows

• 33 currencies against the Malaysian ringgit: AED, AUD, BDT, BHD, BND, CAD, CHF, CNY, DKK, EUR, GBP, HKD, IDR, INR, JOD, JPY, KHR, KRW, MXN, NOK, NZD, PHP, PKR, PLN, QAR, SAR, SEK, SGD, THB, TRY, USD, VND and ZAR. Every value is MYR per 1 unit of the foreign currency.
• The telegraphic transfer (bank buy TT / bank sell tt/od) pair. Malaysian banks publish a daily counter board with separate telegraphic-transfer, demand-draft and bank-note rates, and revise it during the trading day. The pair shown is the TT buying rate against the TT/OD selling rate, which is what a transfer is converted at. Rows quoted per 100 units (JPY, IDR, THB and others) are converted to per 1 unit. Bank Negara Malaysia’s official rate is shown next to each row.
• USD on 15 November 2026: RHB bought at 3.8739 and sold at 4.228 MYR, a spread of 8.74%. The Bank Negara Malaysia official rate was 4.085, so the bank's mid sat -0.83% from it.
• The bank's own timestamp. The page prints a last-updated stamp (05:00:02 PM 13 NOV 2026 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 PHP (4.02%), CHF (7.08%), GBP (7.56%) and the widest KRW (29.59%), VND (25.87%), JOD (24.67%). 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 RHB and other banks in Malaysia

USD on the 16 boards AllRatesToday reads in Malaysia, all captured on 15 November 2026 (the Bank Negara Malaysia official rate was 4.085):

RHB had the 15th narrowest USD spread of the 16. One call to /api/v1/bank-rates/my returns every board in the table at once.

Board rate or official rate?

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

FAQ

Where do the RHB Bank rates come from?

From the bank's own public rates page (https://www.rhbgroup.com/treasury-rates/foreign-exchange/index.html), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price RHB shows, with the mid, the spread and the Bank Negara Malaysia rate added.

Are these the official MYR exchange rates?

No. They are RHB's retail prices for customers. The official rate in Malaysia is the Bank Negara Malaysia 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 RHB 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 RHB 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.
