Gulf Bank Exchange Rate API: KWD Buy and Sell Rates as JSON

Gulf Bank is a Kuwaiti commercial bank founded in 1960. Its treasury exchange rates page lists buying and selling rates against the dinar; currencies it prints with a selling rate only are left out here. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Central Bank of Kuwait official rate and with other banks in Kuwait, and the calls that return them.

What the Gulf Bank board shows

• 18 currencies against the Kuwaiti dinar: AED, AUD, BHD, CAD, CHF, DKK, EUR, GBP, HKD, JPY, NOK, NZD, OMR, QAR, SAR, SEK, SGD and USD. Every value is KWD per 1 unit of the foreign currency.
• The counter board pair. The Kuwaiti dinar is pegged to an undisclosed basket of currencies, so it moves a little against the US dollar each day, and banks quote rates to five or more decimals. The boards here are the banks’ counter rates; several remittance currencies (INR, PKR, BDT, PHP) are printed with a selling rate only and are left out where the bank gives no buying rate. The Central Bank of Kuwait’s official rate is shown next to each row.
• USD on 15 November 2026: Gulf Bank bought at 0.3083 and sold at 0.3104 KWD, a spread of 0.68%. The Central Bank of Kuwait official rate was 0.3088, so the bank's mid sat +0.16% from it.
• No timestamp on the bank's page. Gulf Bank does not print a last-updated time, so bank_updated_at is null and captured_at (when AllRatesToday read the page) is the only time available.
• 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 USD (0.68%), SAR (2.13%), AED (2.13%) and the widest AUD (3.51%), CHF (3.40%), NZD (3.35%). 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 Gulf Bank and other banks in Kuwait

USD on the 8 boards AllRatesToday reads in Kuwait, all captured on 15 November 2026 (the Central Bank of Kuwait official rate was 0.3088):

Gulf Bank had the 2nd narrowest USD spread of the 8. One call to /api/v1/bank-rates/kw returns every board in the table at once.

Board rate or official rate?

The Central Bank of Kuwait rate is the one tax, accounting and customs rules in Kuwait name; nobody transacts at it. Gulf 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 Central Bank of Kuwait endpoint when a rule asks for the official rate.

FAQ

Where do the Gulf Bank rates come from?

From the bank's own public rates page (https://www.e-gulfbank.com/en/treasury/tools/exchange-rates/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Gulf Bank shows, with the mid, the spread and the Central Bank of Kuwait rate added.

Are these the official KWD exchange rates?

No. They are Gulf Bank's retail prices for customers. The official rate in Kuwait is the Central Bank of Kuwait 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 Gulf Bank board updated?

AllRatesToday reads the page every hour. The bank prints no timestamp, so captured_at tells you when the rates were read.

Can I get Gulf Bank 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.
