What the MEF rate is
The Ministry of Economy and Finance (MEF) of Cambodia publishes a daily reference exchange rate for the Cambodian Riel against major foreign currencies. This rate is the official basis used by government agencies, the General Department of Taxation, and many regulated industries when translating foreign-currency amounts into KHR.
Each working day, MEF posts a single bid, ask, and average value per currency. On weekends and public holidays the previously posted rate continues to apply until a new one is issued.
Why accounting teams should use it
Cambodian tax law requires foreign-currency transactions to be translated into KHR at a recognised exchange rate. Using the MEF rate gives you a defensible position in any tax audit because it is the same source the tax authority uses.
Using a single source also makes month-end close more consistent: invoices, supplier bills, and bank movements are all translated against the same benchmark, removing FX noise from your books.
Practical workflow
Most teams take the rate on the invoice date for revenue and expense items, and the rate on the reporting date for balance-sheet items denominated in foreign currency. Keep a copy of the rate you used — auditors increasingly ask for the screenshot or API response that supports each translation.
Because our dashboard pulls the MEF feed directly, you can pick any historical date and reproduce the exact rate that applied on that day.
