Local-currency settlement is often cheaper
Paying a Thai supplier directly in THB is usually cheaper than paying in USD and letting them convert. Several Cambodian banks now support direct THB and VND transfers via regional payment rails.
Watch the spread
Bank spreads on THB and VND can be 2–3 percent wider than on USD. For large payments, request a quote rather than accepting the rack rate.
Document the rate
Capture the actual rate applied by the bank, not just the MEF reference rate. The difference is a real cash cost and should be booked as bank charges or FX loss.
How to Verify the MEF Rate for Your Filing
Whether you are posting a USD invoice, computing month-end FX revaluation, or preparing a customs declaration, the rule is the same: anchor your figure to the official MEF daily bulletin for the relevant valuation date. Use today's official MEF rate from the Cambodia Exchange dashboard for live work, or pick any past date to retrieve the exact rate that applied on that day. Archive the rate evidence (a screenshot or API response) alongside the supporting document — GDT auditors increasingly request the source for every FX translation.

Frequently Asked Questions
- Which exchange rate should I use to book a THB or VND supplier invoice?
- Use the MEF rate for THB or VND on the invoice date for the bookkeeping translation. The actual bank conversion rate may differ; the difference is a realised FX gain or loss when the supplier is paid.
- Why is the bank rate different from the MEF rate?
- Banks add a spread to cover their risk and operating costs. MEF publishes a neutral reference rate; commercial transactions almost always settle at a slightly less favourable rate. Both are normal — they just live in different lines of your ledger.
- Can I batch THB or VND payments to reduce FX cost?
- Often yes. Many Cambodian importers consolidate weekly or fortnightly supplier runs to negotiate a better commercial rate from their bank and reduce per-transaction fees.
