REST, JavaScript and Python examples." canonical: https://allratestoday.com/blog/jeonbuk-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: 2026-11-15T19:06:05.920Z --- Jeonbuk Bank is a regional bank based in Jeonju, North Jeolla, and the founding bank of JB Financial Group. Its exchange-rate page lists remittance send and receive, cash, traveller’s cheque and base rates for 25 currencies. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of Korea official rate and with other banks in South Korea, and the calls that return them. ## What the Jeonbuk Bank board shows - **25 currencies against the South Korean won**: AED, AUD, BHD, CAD, CHF, CNY, DKK, EUR, GBP, HKD, IDR, INR, JPY, KWD, MYR, NOK, NZD, PHP, SAR, SEK, SGD, THB, TWD, USD and VND. Every value is KRW per 1 unit of the foreign currency. - **The remittance receive / send (telegraphic transfer) pair.** Korean banks re-post their boards many times a day (Hana Bank numbers each notice) around a base rate (매매기준율) derived from the Seoul interbank market. Each board has cash, remittance and cheque columns; the pair here is remittance receive and send, the rates an incoming or outgoing transfer uses. Yen, rupiah and dong are quoted per 100 units by the bank and are shown here per 1. - **USD on 15 November 2026**: Jeonbuk Bank bought at 1324.32 and sold at 1351.07 KRW, a spread of 2.00%. The Bank of Korea official rate was 1332.4, so the bank's mid sat +0.40% from it. - **No timestamp on the bank's page.** Jeonbuk 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 15 November 2026, the day collection started.** 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 PHP (1.96%), TWD (1.99%), NOK (2.00%) and the widest VND (2.12%), INR (2.04%), IDR (2.04%). 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 Jeonbuk Bank and other banks in South Korea USD on the 11 boards AllRatesToday reads in South Korea, all captured on 15 November 2026 (the Bank of Korea official rate was 1332.4): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | Hana Bank | 1326.9 | 1353.1 | 1.96% | +0.57% | | KB Kookmin Bank | 1325.6 | 1351.4 | 1.93% | +0.46% | | Woori Bank | 1326.1 | 1351.9 | 1.93% | +0.49% | | IBK Industrial Bank of Korea | 1324.1 | 1349.3 | 1.89% | +0.32% | | SC First Bank | 1324.6 | 1349.9 | 1.89% | +0.36% | | Citibank Korea | 1322.2 | 1352.1 | 2.24% | +0.36% | | BNK Busan Bank | 1323.38 | 1350.12 | 2.00% | +0.33% | | BNK Kyongnam Bank | 1323.4 | 1348.79 | 1.90% | +0.28% | | Kwangju Bank | 1323.7 | 1349.9 | 1.96% | +0.33% | | **Jeonbuk Bank** | 1324.32 | 1351.07 | 2.00% | +0.40% | | Suhyup Bank | 1324.5 | 1350.7 | 1.96% | +0.39% | Jeonbuk Bank had the 10th narrowest USD spread of the 11. One call to `/api/v1/bank-rates/kr` 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 Korea rate is the one tax, accounting and customs rules in South Korea name; nobody transacts at it. Jeonbuk 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 Korea endpoint](https://allratestoday.com/central-bank-rates-api/bok/) when a rule asks for the official rate. ## FAQ ### Where do the Jeonbuk Bank rates come from? From the bank's own public rates page (https://ibs.jbbank.co.kr/P_FEX312011_10.act), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Jeonbuk Bank shows, with the mid, the spread and the Bank of Korea rate added. ### Are these the official KRW exchange rates? No. They are Jeonbuk Bank's retail prices for customers. The official rate in South Korea is the Bank of Korea 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 Jeonbuk 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 Jeonbuk Bank rates for a past date? Yes, from 15 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. ## Jeonbuk Bank rates, as JSON Free API key, hourly board captures, the official rate alongside.
