REST, JavaScript and Python examples." canonical: https://allratestoday.com/blog/cimb-bank-singapore-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: 2026-11-15T19:13:43.373Z --- CIMB Bank Singapore is the Singapore arm of Malaysia’s CIMB Group. Its foreign exchange rates page lists TT and demand-draft selling and buying rates for about 15 currencies against the Singapore dollar. 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 Singapore, and the calls that return them. ## What the CIMB Singapore board shows - **13 currencies against the Singapore dollar**: AUD, CAD, CHF, DKK, EUR, GBP, HKD, JPY, NOK, NZD, SEK, THB and USD. Every value is SGD per 1 unit of the foreign currency. - **The telegraphic transfer buy / sell pair.** The Monetary Authority of Singapore manages the Singapore dollar against an undisclosed basket of currencies rather than a single peg. Singapore banks price transfers in tiers by amount; the rate shown is the telegraphic-transfer pair for the smallest tier, the one a retail transfer gets. The MAS official rate is shown next to each row. - **USD on 15 November 2026**: CIMB Singapore bought at 1.2672 and sold at 1.3074 SGD, a spread of 3.12%. The Monetary Authority of Singapore official rate was 1.2863, so the bank's mid sat +0.08% from it. - **The bank's own timestamp.** The page prints a last-updated stamp (`6:15 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 HKD (2.80%), GBP (2.86%), CHF (2.91%) and the widest THB (7.14%), NZD (6.55%), NOK (5.82%). 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 CIMB Singapore and other banks in Singapore USD on the 10 boards AllRatesToday reads in Singapore, all captured on 15 November 2026 (the Monetary Authority of Singapore official rate was 1.2863): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | OCBC | 1.2755 | 1.3001 | 1.91% | +0.12% | | DBS Bank | 1.2757 | 1.3011 | 1.97% | +0.16% | | United Overseas Bank | 1.275 | 1.299 | 1.86% | +0.05% | | Maybank Singapore | 1.2737 | 1.3167 | 3.32% | +0.69% | | RHB Singapore | 1.2718 | 1.3021 | 2.35% | +0.05% | | State Bank of India Singapore | 1.2685 | 1.2985 | 2.34% | -0.22% | | Bank of China Singapore | 1.28 | 1.296 | 1.24% | +0.13% | | **CIMB Bank Singapore** | 1.2672 | 1.3074 | 3.12% | +0.08% | | HSBC Singapore | 1.2613 | 1.313 | 4.02% | +0.07% | | ICBC Singapore | 1.2782 | 1.2982 | 1.55% | +0.15% | CIMB Singapore had the 8th narrowest USD spread of the 10. One call to `/api/v1/bank-rates/sg` 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 Monetary Authority of Singapore rate is the one tax, accounting and customs rules in Singapore name; nobody transacts at it. CIMB Singapore'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 Singapore endpoint](https://allratestoday.com/central-bank-rates-api/mas/) when a rule asks for the official rate. ## FAQ ### Where do the CIMB Bank Singapore rates come from? From the bank's own public rates page (https://www.cimb.com.sg/en/personal/help-support/rates-charges/rates/foreign-exchange-rates.html), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price CIMB Singapore shows, with the mid, the spread and the Monetary Authority of Singapore rate added. ### Are these the official SGD exchange rates? No. They are CIMB Singapore's retail prices for customers. The official rate in Singapore 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 CIMB Singapore 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 CIMB Singapore 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. ## CIMB Bank Singapore rates, as JSON Free API key, hourly board captures, the official rate alongside.
