--- title: "State Bank of Mongolia Exchange Rate API: MNT Buy and Sell Rates as JSON" description: "State Bank of Mongolia's non-cash rates for 7 currencies against the Mongolian tugrik, read hourly from the bank's own page and served as JSON with the Bank of Mongolia official rate alongside. REST, JavaScript and Python examples." canonical: https://allratestoday.com/blog/state-bank-of-mongolia-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: 2026-11-15T19:13:51.751Z --- The State Bank of Mongolia (Töriin Bank) is a state-owned bank headquartered in Ulaanbaatar. Its site lists cash and non-cash buying and selling rates against the tugrik for seven currencies with the Bank of Mongolia rate. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of Mongolia official rate and with other banks in Mongolia, and the calls that return them. ## What the State Bank board shows - **7 currencies against the Mongolian tugrik**: AUD, CNY, EUR, GBP, JPY, KRW and USD. Every value is MNT per 1 unit of the foreign currency. - **The non-cash pair.** Mongolian banks print separate cash and non-cash buying and selling rates against the tugrik for a dozen or more currencies, with the Bank of Mongolia rate alongside. The non-cash US dollar spread is usually around 0.3%, and cash spreads are wider. The Bank of Mongolia official rate is shown next to each row. - **USD on 15 November 2026**: State Bank bought at 3596 and sold at 3604 MNT, a spread of 0.22%. The Bank of Mongolia official rate was 3603.46, so the bank's mid sat -0.10% from it. - **The bank's own timestamp.** The page prints a last-updated stamp (`2026/11/15` on the board above), returned as `bank_updated_at` next to our `captured_at`. - **Every day's board is kept permanently, from 14 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 USD (0.22%), CNY (0.81%), JPY (1.86%) and the widest KRW (4.08%), AUD (3.87%), EUR (2.21%). 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 State Bank and other banks in Mongolia USD on the 8 boards AllRatesToday reads in Mongolia, all captured on 15 November 2026 (the Bank of Mongolia official rate was 3603.46): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | Khan Bank | 3594 | 3604 | 0.28% | -0.12% | | Golomt Bank | 3595 | 3605 | 0.28% | -0.10% | | XacBank | 3598 | 3605 | 0.19% | -0.05% | | **State Bank of Mongolia** | 3596 | 3604 | 0.22% | -0.10% | | Chinggis Khaan Bank | 3593.5 | 3605.5 | 0.33% | -0.11% | | Trans Bank | 3596 | 3604 | 0.22% | -0.10% | | Bogd Bank | 3596 | 3604 | 0.22% | -0.10% | | Trade and Development Bank of Mongolia | 3596 | 3604 | 0.22% | -0.10% | State Bank had the 2nd narrowest USD spread of the 8.

The Bank of Mongolia rate is the one tax, accounting and customs rules in Mongolia name; nobody transacts at it. State Bank'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 Mongolia endpoint](https://allratestoday.com/central-bank-rates-api/bom/) when a rule asks for the official rate. ## FAQ ### Where do the State Bank of Mongolia rates come from? From the bank's own public rates page (https://statebank.mn/personal), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price State Bank shows, with the mid, the spread and the Bank of Mongolia rate added. ### Are these the official MNT exchange rates? No. They are State Bank's retail prices for customers. The official rate in Mongolia is the Bank of Mongolia 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 State Bank 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 State Bank rates for a past date? Yes, from 14 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. ## State Bank of Mongolia rates, as JSON Free API key, hourly board captures, the official rate alongside.
