Liechtensteinische Landesbank Exchange Rate API: CHF Buy and Sell Rates as JSON

Liechtensteinische Landesbank (LLB) is the oldest bank in Liechtenstein and is majority-owned by the Principality. Its Foreign exchange and precious metal page lists non-cash buy and sell rates in francs for 25 currencies up to CHF 10’000, with bank-note and metal prices alongside. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Swiss National Bank official rate and with other banks in Liechtenstein, and the calls that return them.

What the LLB board shows

• 25 currencies against the Swiss franc: AED, AUD, BAM, CAD, CZK, DKK, EUR, GBP, HKD, HUF, ISK, JPY, MXN, NOK, NZD, PLN, RON, RSD, RUB, SEK, SGD, THB, TRY, USD and ZAR. Every value is CHF per 1 unit of the foreign currency.
• The foreign exchange (non-cash) buy / sell, up to CHF 10'000 pair. Liechtenstein uses the Swiss franc, so its banks quote foreign currencies in francs, with Devisen (non-cash) and bank-note lists like Swiss banks and per-100 quotes for currencies such as SEK, NOK, DKK and JPY. The Swiss National Bank rate is the reference shown next to each row.
• USD on 15 November 2026: LLB bought at 0.8252 and sold at 0.8543 CHF, a spread of 3.46%. The Swiss National Bank official rate was 0.837, so the bank's mid sat +0.33% from it.
• The bank's own timestamp. The page prints a last-updated stamp (2026-11-13 22:05:30 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 GBP (3.41%), EUR (3.41%), NOK (3.41%) and the widest RSD (9.28%), ISK (9.24%), BAM (9.22%). 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.

Board rate or official rate?

The Swiss National Bank rate is the one tax, accounting and customs rules in Liechtenstein name; nobody transacts at it. LLB'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 Swiss National Bank endpoint when a rule asks for the official rate.

FAQ

Where do the Liechtensteinische Landesbank rates come from?

From the bank's own public rates page (https://www.llb.li/en/private/investing/direct-investments/foreign-exchange-and-precious-metal), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price LLB shows, with the mid, the spread and the Swiss National Bank rate added.

Are these the official CHF exchange rates?

No. They are LLB's retail prices for customers. The official rate in Liechtenstein is the Swiss National Bank 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 LLB 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 LLB 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.
