By [Madhushan](https://allratestoday.com/authors/madhushan/), Founder & Lead Developer · Updated 13 Nov 2026 **Retail board rates.** These are the prices PostFinance displayed on [its own rates page](https://www.postfinance.ch/de/support/services/tools-rechner/wahrungsrechner.html) when we last read it. They are indicative, change through the day, and are not official rates. For the reference rate, see the [Swiss National Bank](https://allratestoday.com/central-bank-rates-api/snb/). ![](https://allratestoday.com/logos/banks/postfinance.webp) ## About PostFinance [www.postfinance.ch](https://www.postfinance.ch/) PostFinance is the financial services arm of Swiss Post.

Board shown: **Giro (account) exchange rates, up to CHF 50'000**.

The others are on the bank’s own page. | Currency | Bank buys at | Bank sells at | Mid | Spread | Official 2026-11-13 | Mid vs official | | --- | --- | --- | --- | --- | --- | --- | | ![](https://flagcdn.com/24x18/us.png)`USD` | 0.8250 | 0.8458 | 0.8354 | 2.49% | 0.8370 | -0.19% | | ![](https://flagcdn.com/24x18/eu.png)`EUR` | 0.9133 | 0.9355 | 0.9244 | 2.40% | 0.9255 | -0.12% | | ![](https://flagcdn.com/24x18/gb.png)`GBP` | 1.0918 | 1.1194 | 1.1056 | 2.50% | 1.1076 | -0.18% | | ![](https://flagcdn.com/24x18/jp.png)`JPY` | 0.005161 | 0.005291 | 0.005226 | 2.49% | 0.005235 | -0.17% | | ![](https://flagcdn.com/24x18/ca.png)`CAD` | 0.5786 | 0.5932 | 0.5859 | 2.49% | 0.5859 | -0.01% | | ![](https://flagcdn.com/24x18/au.png)`AUD` | 0.5594 | 0.5764 | 0.5679 | 2.99% | 0.5790 | -1.92% | | ![](https://flagcdn.com/24x18/cz.png)`CZK` | 0.03734 | 0.03848 | 0.03791 | 3.00% | 0.03810 | -0.51% | | ![](https://flagcdn.com/24x18/dk.png)`DKK` | 0.1222 | 0.1252 | 0.1237 | 2.42% | 0.1242 | -0.41% | | ![](https://flagcdn.com/24x18/hk.png)`HKD` | 0.1049 | 0.1081 | 0.1065 | 3.00% | 0.1056 | +0.86% | | ![](https://flagcdn.com/24x18/hu.png)`HUF` | 0.002485 | 0.002573 | 0.002529 | 3.48% | 0.002539 | -0.39% | | ![](https://flagcdn.com/24x18/ma.png)`MAD` | 0.08245 | 0.08755 | 0.08500 | 6.00% | — | — | | ![](https://flagcdn.com/24x18/no.png)`NOK` | 0.08640 | 0.08860 | 0.08750 | 2.51% | 0.08759 | -0.10% | | ![](https://flagcdn.com/24x18/nz.png)`NZD` | 0.4562 | 0.4700 | 0.4631 | 2.98% | 0.4669 | -0.82% | | ![](https://flagcdn.com/24x18/pl.png)`PLN` | 0.2063 | 0.2135 | 0.2099 | 3.43% | 0.2119 | -0.94% | | ![](https://flagcdn.com/24x18/se.png)`SEK` | 0.08240 | 0.08440 | 0.08340 | 2.40% | 0.08320 | +0.24% | | ![](https://flagcdn.com/24x18/sg.png)`SGD` | 0.6395 | 0.6589 | 0.6492 | 2.99% | 0.6474 | +0.28% | | ![](https://flagcdn.com/24x18/th.png)`THB` | 0.02427 | 0.02513 | 0.02470 | 3.50% | 0.02463 | +0.29% | | ![](https://flagcdn.com/24x18/za.png)`ZAR` | 0.04880 | 0.05080 | 0.04980 | 4.02% | 0.05003 | -0.46% | All values are CHF per 1 unit of the currency.

Every price is CHF per 1 unit of `ccy`. | | `buy` | What the bank pays you in CHF for one unit of foreign currency. | | `sell` | What the bank charges you in CHF for one unit — the rate for sending money abroad. | | `mid`, `spread_pct` | Midpoint of buy and sell; spread = (sell − buy) ÷ mid, in percent. | | `official`, `vs_official_pct` | The Swiss National Bank rate for the same currency and how far the bank’s mid sits from it. | | `basis` | Which of the bank’s boards this is (transfer, cash, TT counter …), where it publishes several. | | `captured_at` | When AllRatesToday read the bank’s page (UTC).

Any plan’s key works, the free one included. - `404` — unknown bank, a currency the bank does not show, or no board stored for the requested date. - `400` — `date` not in `YYYY-MM-DD` form, or in the future. - Each call counts against your plan. Responses can be cached for five minutes; past-day boards never change. - Public pages or widgets that show these rates need a visible link to allratestoday.com. ## Why use bank board rates through an API? The Swiss National Bank official rate is what accounting, tax and customs rules name, but it is not what a customer pays at the counter or in an app. Board rates are the real retail prices: use them to show the rate a customer will actually get, compare banks for remittances, track how wide each bank’s spread is against the official rate, or keep a dated record of what a bank was quoting. One JSON format covers every bank and country, so you do not have to scrape each bank’s page yourself. ## Start calling the PostFinance board API Free key, JSON responses, hourly board captures with the official rate alongside.

JSON needs an API key: `https://allratestoday.com/api/v1/bank-rates/ch/postfinance`. ## Frequently asked questions ### Is the PostFinance rate the official Switzerland exchange rate? No. PostFinance sets its own buying and selling rates and changes them through the day. The official rate is published once per business day by the Swiss National Bank; it is shown in the Official column and is the figure accounting, tax and customs rules refer to. ### Which PostFinance rate applies when I send money abroad? The sell rate: you are buying foreign currency from the bank. When you convert foreign currency into CHF, the buy rate applies. Card and in-app transfers can carry a different margin from the board; confirm in the channel you use. ### How current is this table? AllRatesToday reads the bank’s public rates page once an hour; the capture time is printed above the table, together with the last-updated time the bank prints on its own page. Rates may have changed since. ## Compare [All Switzerland banks side by sideBest buy and sell per currency](https://allratestoday.com/bank-exchange-rate-api/ch/) [Zürcher KantonalbankBoard rates](https://allratestoday.com/bank-exchange-rate-api/ch/zkb/)[Raiffeisen SchweizBoard rates](https://allratestoday.com/bank-exchange-rate-api/ch/raiffeisench/)[Migros BankBoard rates](https://allratestoday.com/bank-exchange-rate-api/ch/migrosbank/)[Banque Cantonale VaudoiseBoard rates](https://allratestoday.com/bank-exchange-rate-api/ch/bcvaud/)[St.Galler KantonalbankBoard rates](https://allratestoday.com/bank-exchange-rate-api/ch/sgkb/)[Berner KantonalbankBoard rates](https://allratestoday.com/bank-exchange-rate-api/ch/bekb/) [Swiss National BankOfficial rate, daily, with history](https://allratestoday.com/central-bank-rates-api/snb/)
