Banco Comercial de Macau Exchange Rate API: MOP Buy and Sell Rates as JSON

Banco Comercial de Macau (BCM) is a Macau bank owned by Hong Kong’s Dah Sing Financial group. Its exchange-rate page lists telegraphic transfer buy and sell rates in patacas and Hong Kong dollars for ten currencies, as used on its e-banking channels. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Monetary Authority of Macao official rate and with other banks in Macau, and the calls that return them.

What the BCM board shows

• 10 currencies against the Macanese pataca: AUD, CAD, CHF, CNY, EUR, GBP, HKD, JPY, NZD and USD. Every value is MOP per 1 unit of the foreign currency.
• The telegraphic transfer buy / sell (e-channel rates) pair. The pataca is pegged to the Hong Kong dollar (about MOP 1.03 per HKD), so Macau banks quote against both the pataca and the Hong Kong dollar. The rates here are pataca per unit for remittances. The Monetary Authority of Macao official rate is shown next to each row.
• USD on 15 November 2026: BCM bought at 8.0739 and sold at 8.1024 MOP, a spread of 0.35%. The Monetary Authority of Macao official rate was 8.0798, so the bank's mid sat +0.10% from it.
• The bank's own timestamp. The page prints a last-updated stamp (2026-11-13 18:58 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 HKD (0.15%), USD (0.35%), CAD (0.50%) and the widest CNY (1.82%), GBP (0.57%), NZD (0.55%). 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 Monetary Authority of Macao rate is the one tax, accounting and customs rules in Macau name; nobody transacts at it. BCM'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 Monetary Authority of Macao endpoint when a rule asks for the official rate.

FAQ

Where do the Banco Comercial de Macau rates come from?

From the bank's own public rates page (https://www.bcm.com.mo/en/market_n1.php), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price BCM shows, with the mid, the spread and the Monetary Authority of Macao rate added.

Are these the official MOP exchange rates?

No. They are BCM's retail prices for customers. The official rate in Macau is the Monetary Authority of Macao 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 BCM 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 BCM 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.
