REST, JavaScript and Python examples." canonical: https://allratestoday.com/blog/jmmb-bank-exchange-rate-api/ source: AllRatesToday (https://allratestoday.com/) — Markdown mirror of the page above; index of all pages at https://allratestoday.com/llms.txt generated: 2026-11-15T19:12:07.257Z --- JMMB Bank is the banking arm of the Jamaica-based JMMB Group. Its rates page lists cash and cheque buying rates and a selling rate for USD, EUR, GBP and CAD. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of Jamaica official rate and with other banks in Jamaica, and the calls that return them. ## What the JMMB board shows - **4 currencies against the Jamaican dollar**: CAD, EUR, GBP and USD. Every value is JMD per 1 unit of the foreign currency. - **The cheques (non-cash) pair.** Jamaican banks print separate buying rates for cash and for demand drafts, cheques and transfers, against one selling rate; the Jamaican dollar floats and boards are mostly USD, GBP, CAD and EUR. The rates here are the non-cash buying rate against the selling rate. The Bank of Jamaica official rate is shown next to each row. - **USD on 15 November 2026**: JMMB bought at 154.5 and sold at 159.5 JMD, a spread of 3.19%. The Bank of Jamaica official rate was 159.22, so the bank's mid sat -1.39% from it. - **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 GBP (2.87%), USD (3.19%), EUR (3.43%) and the widest CAD (4.17%), EUR (3.43%), USD (3.19%). 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 JMMB and other banks in Jamaica USD on the 5 boards AllRatesToday reads in Jamaica, all captured on 15 November 2026 (the Bank of Jamaica official rate was 159.22): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | Scotiabank Jamaica | 152.67 | 159.55 | 4.41% | -1.95% | | **JMMB Bank** | 154.5 | 159.5 | 3.19% | -1.39% | | National Commercial Bank Jamaica | 152.3 | 159.3 | 4.49% | -2.15% | | First Global Bank | 153 | 160 | 4.47% | -1.71% | | JN Bank | 152.5 | 159.5 | 4.49% | -2.02% | JMMB had the narrowest USD spread of the 5. One call to `/api/v1/bank-rates/jm` 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 Bank of Jamaica rate is the one tax, accounting and customs rules in Jamaica name; nobody transacts at it. JMMB'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 of Jamaica endpoint](https://allratestoday.com/central-bank-rates-api/bojm/) when a rule asks for the official rate. ## FAQ ### Where do the JMMB Bank rates come from? From the bank's own public rates page (https://jm.jmmb.com/rates-fees), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price JMMB shows, with the mid, the spread and the Bank of Jamaica rate added. ### Are these the official JMD exchange rates? No. They are JMMB's retail prices for customers. The official rate in Jamaica is the Bank of Jamaica 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 JMMB 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 JMMB 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. ## JMMB Bank rates, as JSON Free API key, hourly board captures, the official rate alongside.
