Understanding Multi-Currency Transactions and Reporting

Why document currency, exchange rates and base-currency reporting must be kept distinct.

A business may buy, sell or hold bank balances in foreign currencies while keeping its statutory accounting records in a base currency. A sound system preserves both the original transaction currency and its base-currency equivalent.

Each foreign-currency document should record the currency, applicable exchange rate, foreign amount and converted base amount. Payments may occur at a different rate, creating realised exchange differences. Outstanding balances may also require revaluation at a reporting date.

Operational users need to see the currency in which a document was agreed, while finance teams need consistent base-currency ledgers and reports. Hiding either side makes reconciliation and audit work more difficult.

Exchange-rate sources, approval rules and revaluation policies should be documented and applied consistently in line with the organisation’s accounting policies.

Key considerations

• Preserve transaction and base-currency amounts
• Record the rate and date used for conversion
• Recognise exchange differences through controlled entries
• Report consistently in the company base currency
