Foreign currency translation of the banking book and net investment exposures

Banks routinely carry foreign-currency-denominated monetary assets and liabilities (loans, deposits, debt securities) that must be retranslated at the closing rate at each reporting date with the exchange difference taken to profit or loss, while a net investment in a foreign branch or subsidiary with a different functional currency is translated as a whole and the resulting difference is recognized in OCI until disposal. Confusing the two, most often by running an intercompany loan that is, in substance, part of the net investment through P&L instead of OCI, misstates both current-period earnings and equity, and because FX-sensitive positions are large relative to a bank's capital, the error can be material even when individual balances look routine.

Has the functional currency of each foreign branch or subsidiary been determined by the currency that primarily drives its pricing, funding, and operating costs, rather than the currency of incorporation or presentation currency? Are foreign-currency monetary items (loans, deposits, securities) retranslated at the closing rate through profit or loss, distinct from net investments in foreign operations translated through OCI? Has any intercompany monetary item that is, in substance, part of the net investment (settlement neither planned nor likely) been identified so its exchange differences go to OCI rather than profit or loss?

1. Determine the functional currency of each foreign branch or subsidiary based on the currency that primarily drives its pricing, funding, and operating costs, not the currency of incorporation or the group's presentation currency.
2. For monetary items held directly (loans, deposits, securities) denominated in a currency other than the entity's own functional currency, retranslate at the closing rate at each reporting date and recognize the exchange difference in profit or loss.
3. For a foreign operation with a different functional currency, translate its assets and liabilities at the closing rate and income and expenses at rates approximating transaction dates, recognizing the resulting translation difference in OCI (foreign currency translation reserve).
4. Identify any intercompany monetary item that is, in substance, part of the net investment in the foreign operation (settlement neither planned nor likely in the foreseeable future) and recognize its exchange differences in OCI, not P&L, reclassifying the cumulative amount to profit or loss only on disposal or substantial liquidation of that operation.
5. Reassess functional currency only when there is a genuine change in the underlying economic indicators, not routine currency mix fluctuations.

Retranslate foreign-currency monetary items at the closing spot rate at each reporting date; non-monetary items measured at historical cost remain at the exchange rate on the transaction date and are not retranslated. For net investment translation, use the closing rate for the statement of financial position and a rate approximating actual transaction-date rates (e.g., an average rate if it is a reasonable approximation) for the income statement. Track the cumulative foreign currency translation reserve by foreign operation so the correct amount can be identified and reclassified to profit or loss on disposal, and monitor which intercompany balances qualify as net investment items versus ordinary receivables/payables expected to be settled.

Disclose: (1) the amount of exchange differences recognized in profit or loss during the period; (2) the amount recognized in OCI as part of the foreign currency translation reserve, with a reconciliation of the opening and closing balance including reclassifications on disposal; (3) the functional currency of significant foreign branches or subsidiaries and the judgment applied in determining it; (4) which intercompany monetary items are treated as part of the net investment and the basis for that conclusion; (5) foreign exchange sensitivity of the banking book as part of market risk disclosures under IFRS 7.

• treating the group'

• failing to reclassify the cumulative translation reserve to profit or loss on disposal or substantial liquidation of a foreign operation
• using a period-end spot rate to translate income and expenses when rates have fluctuated significantly, without a reasonable averaging approximation
• not distinguishing monetary from non-monetary foreign currency items when applying retranslation.
