Its currency page lists general buy and sell rates in krónur for about 27 currencies, with the rate time. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Central Bank of Iceland official rate and with other banks in Iceland, and the calls that return them. ## What the Íslandsbanki board shows - **27 currencies against the Icelandic króna**: AUD, BGN, BRL, CAD, CHF, CZK, DKK, EUR, GBP, HKD, HUF, ILS, INR, JPY, KRW, MXN, NOK, NZD, PLN, RUB, SEK, SGD, TRY, TWD, USD, XDR and ZAR. Every value is ISK per 1 unit of the foreign currency. - **The general (almennt) exchange rate for transfers and accounts, buy / sell pair.** Icelandic banks quote krónur per 1 unit of foreign currency and publish a general (almennt) rate for transfers and accounts, separate from notes and card rates; the general rate is the pair shown here. The Central Bank of Iceland publishes one reference rate per business day, shown next to each row. - **USD on 15 November 2026**: Íslandsbanki bought at 123.4 and sold at 124.22 ISK, a spread of 0.66%. The Central Bank of Iceland official rate was 123.6, so the bank's mid sat +0.17% from it. - **The bank's own timestamp.** The page prints a last-updated stamp (`2026-11-13T16:47:00.000Z` 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 KRW (0.65%), DKK (0.66%), EUR (0.66%) and the widest TRY (0.81%), CAD (0.74%), XDR (0.73%). 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 Íslandsbanki and other banks in Iceland USD on the 5 boards AllRatesToday reads in Iceland, all captured on 15 November 2026 (the Central Bank of Iceland official rate was 123.6): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | Landsbankinn | 123.23 | 124.2 | 0.78% | +0.09% | | Arion banki | 123.45 | 124.32 | 0.70% | +0.23% | | **Íslandsbanki** | 123.4 | 124.22 | 0.66% | +0.17% | | Kvika banki | 123.18 | 124.04 | 0.70% | +0.01% | | Smári sparisjóður | 123.18 | 124.04 | 0.70% | +0.01% | Íslandsbanki had the narrowest USD spread of the 5.

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