ACLEDA Bank Lao Exchange Rate API: LAK Buy and Sell Rates as JSON

ACLEDA Bank Lao is the Lao subsidiary of Cambodia’s ACLEDA Bank, headquartered in Vientiane. Its foreign-exchange page lists buying and selling rates in kip for nine currencies, with TT rates for the US dollar and Thai baht. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of the Lao PDR official rate and with other banks in Laos, and the calls that return them.

What the ACLEDA Lao board shows

• 9 currencies against the Laotian kip: AUD, CAD, EUR, GBP, JPY, KHR, THB, USD and VND. Every value is LAK per 1 unit of the foreign currency.
• The counter bid / ask (equal to the TT pair where printed) pair. Lao banks print separate buying rates for notes, bills and electronic transfers against one selling rate, set each morning around the Bank of the Lao PDR reference rate. The rates here are the electronic-transfer buy against the sell. The Bank of the Lao PDR official rate is shown next to each row.
• USD on 15 November 2026: ACLEDA Lao bought at 22504 and sold at 22631 LAK, a spread of 0.56%. The Bank of the Lao PDR official rate was 22630, so the bank's mid sat -0.28% from it.
• The bank's own timestamp. The page prints a last-updated stamp (November 13, 2026 10:27 am 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 USD (0.56%), THB (1.63%), EUR (1.98%) and the widest AUD (4.88%), VND (4.87%), CAD (4.87%). 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 Bank of the Lao PDR rate is the one tax, accounting and customs rules in Laos name; nobody transacts at it. ACLEDA Lao'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 the Lao PDR endpoint when a rule asks for the official rate.

FAQ

Where do the ACLEDA Bank Lao rates come from?

From the bank's own public rates page (https://www.acledabank.com.la/la/eng/ps_cmforeignexchange), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price ACLEDA Lao shows, with the mid, the spread and the Bank of the Lao PDR rate added.

Are these the official LAK exchange rates?

No. They are ACLEDA Lao's retail prices for customers. The official rate in Laos is the Bank of the Lao PDR 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 ACLEDA Lao 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 ACLEDA Lao 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.
