IAS 21 answers three separate questions that are routinely conflated: what currency does this entity actually operate in, how do transactions in other currencies get recorded, and how does a foreign subsidiary's financial statements get folded into a group presented in a different currency.

The first question has no answer the entity may choose. The third question has an answer the entity may choose entirely. Confusing the two produces some of the most persistent errors in foreign currency accounting.

The distinction that runs through everything else is monetary versus non-monetary. Get that classification right and the translation rules follow almost mechanically. Get it wrong and the error compounds through every subsequent reporting date.


Functional Currency Is Determined, Not Selected

The functional currency is the currency of the primary economic environment in which the entity operates. It is a matter of fact to be determined from evidence, not a policy choice.

This is the single most important structural point in IAS 21. A reporting entity has no choice regarding its functional currency and must determine the currency that reflects its operations. Where the determination is wrong, essentially every number in the financial statements is affected, because functional currency determines which items are foreign currency items in the first place.

Primary Indicators

The primary indicators carry the most weight and address the currency that dominates the entity's operating economics:

The currency that mainly influences sales prices for goods and services, which is often the currency in which sales prices are denominated and settled.

The currency of the country whose competitive forces and regulations mainly determine the sales prices of the entity's goods and services.

The currency that mainly influences labour, material and other costs of providing goods or services, which is often the currency in which such costs are denominated and settled.

Secondary Indicators

Where the primary indicators are not decisive, secondary indicators provide supporting evidence:

The currency in which funds from financing activities are generated, meaning issuing debt and equity instruments.

The currency in which receipts from operating activities are usually retained.

Additional Factors for a Foreign Operation

Where the entity is a foreign operation within a group, further factors address whether it operates as an extension of the reporting entity or with significant autonomy:

Whether the activities are carried out as an extension of the reporting entity rather than with a significant degree of autonomy.

Whether transactions with the reporting entity are a high or low proportion of the foreign operation's activities.

Whether cash flows from the foreign operation's activities directly affect the reporting entity's cash flows and are readily available for remittance.

Whether cash flows from the foreign operation's activities are sufficient to service existing and normally expected debt obligations without funds being made available by the reporting entity.

A sales office that simply distributes goods imported from its parent, remits proceeds immediately, and depends on parent funding is an extension of the parent and will typically have the parent's functional currency. A subsidiary that manufactures locally, sells locally, borrows locally, and retains its own cash generally has the local currency as its functional currency.

Where indicators are mixed and the determination is not obvious, management uses judgment, giving priority to the primary indicators, and discloses the judgment where it is significant.

Changing Functional Currency

An entity's functional currency changes only when there is a change in the underlying transactions, events and conditions. It does not change because management would prefer a different currency, and it does not change simply because exchange rates have moved.

Where the functional currency does change, the entity applies the translation procedures applicable to the new functional currency prospectively from the date of the change. Prior periods are not restated.


Presentation Currency Is a Choice

By contrast, an entity may present its financial statements in any currency it chooses.

An Indian company may present in rupees, US dollars, or any other currency, provided it applies the translation requirements correctly and discloses both the presentation currency and the functional currency where they differ.

The functional currency drives measurement. The presentation currency drives display. An entity with a rupee functional currency presenting in dollars measures everything in rupees first and then translates for presentation; it does not simply record transactions in dollars.


Monetary Versus Non-Monetary: The Definition That Drives Everything

Monetary items are units of currency held, and assets and liabilities to be received or paid in a fixed or determinable number of units of currency.

Non-monetary items lack the right to receive, or the obligation to deliver, a fixed or determinable number of units of currency.

The test is whether the item represents a claim to, or obligation for, a fixed or determinable number of currency units. Not whether it is a financial instrument, not whether it is current or non-current, and not whether it will eventually be settled in cash.

MonetaryNon-monetary
Cash and bank balancesProperty, plant and equipment
Trade receivables and payablesIntangible assets
Loans receivable and payableGoodwill
Debt securities heldInventories
Accrued interestEquity investments
Provisions to be settled in cash at a determinable amountAdvance consideration paid or received
Lease liabilitiesRight-of-use assets
Dividends payablePrepaid expenses

Two entries in that table deserve comment.

Advance consideration is non-monetary. A prepayment made in a foreign currency does not confer a right to receive currency; it confers a right to receive goods or services. It is therefore non-monetary and is translated at the rate on the date the advance was paid, and not retranslated afterwards. This has a direct consequence for the exchange rate used to record the eventual purchase, which is the subject of IFRIC 22, covered in Post 87.

A lease liability is monetary while the corresponding right-of-use asset is not. The liability is an obligation to pay a determinable number of currency units and is retranslated at each reporting date; the ROU asset is measured at historical cost in the functional currency and is not. For an Indian airline with USD-denominated aircraft leases, this asymmetry produces exchange differences in profit or loss on the liability with no offsetting movement on the asset, which is precisely the pattern noted in Post 32.


Translation at Each Reporting Date: Three Rules

At the end of each reporting period:

Monetary items are translated at the closing rate, being the spot exchange rate at the reporting date.

Non-monetary items measured at historical cost are translated at the historical rate, being the exchange rate at the date of the transaction. They are not retranslated.

Non-monetary items measured at fair value are translated at the rate on the date the fair value was determined.

The logic is consistent. Monetary items represent claims to a fixed number of foreign currency units, so their functional currency value moves as the rate moves. Non-monetary items at historical cost were measured once, at a point in time, and that measurement is not affected by subsequent rate movements. Non-monetary items at fair value are remeasured at a specific date, so the rate at that same date is the appropriate one.


Where Exchange Differences Go

On monetary items, exchange differences are recognised in profit or loss in the period in which they arise. This is the general rule and it covers the great majority of exchange differences.

On non-monetary items, the exchange component follows the item. Where a gain or loss on a non-monetary item is recognised in other comprehensive income, any exchange component of that gain or loss is also recognised in OCI. Where the gain or loss is recognised in profit or loss, the exchange component is recognised in profit or loss.

This follow-the-item principle mirrors the treatment established for deferred tax in Post 62 and applies for the same reason: an exchange difference on a revaluation surplus recognised in OCI belongs in OCI, because the underlying movement it relates to is there.

On a monetary item forming part of a net investment in a foreign operation, exchange differences are recognised in OCI in the consolidated financial statements, accumulated in a separate component of equity, and reclassified to profit or loss on disposal of the foreign operation.

A monetary item qualifies as part of the net investment where settlement is neither planned nor likely to occur in the foreseeable future. A long-term intragroup loan to a foreign subsidiary with no repayment expectation is the standard case. In the individual financial statements of either entity, the exchange difference still goes to profit or loss; the OCI treatment applies only on consolidation.

Hedging of a net investment in a foreign operation raises further questions addressed by IFRIC 16, covered in Post 85.


Translating a Foreign Operation for Consolidation

Where a group includes a foreign operation whose functional currency differs from the group's presentation currency, that operation's results and financial position are translated as follows:

Assets and liabilities, including goodwill and fair value adjustments arising on acquisition, are translated at the closing rate at the reporting date.

Income and expenses are translated at the exchange rates at the dates of the transactions. An average rate for the period may be used as a practical approximation, provided rates have not fluctuated significantly.

All resulting exchange differences are recognised in other comprehensive income and accumulated in a foreign currency translation reserve within equity.

The translation reserve arises because assets and liabilities are translated at closing rate while income and expenses are translated at transaction or average rates, and because the opening net assets are translated at a different rate from the closing net assets. The difference is not an error; it is the arithmetic consequence of applying different rates to different components.

On disposal of the foreign operation, the cumulative amount in the translation reserve relating to that operation is reclassified from equity to profit or loss.

Worked Example: Consolidating a Foreign Subsidiary

An Indian parent with a rupee functional and presentation currency holds a wholly owned US subsidiary with a USD functional currency.

At the start of the year the subsidiary's net assets were USD 40 million and the exchange rate was Rs. 83.00. During the year the subsidiary earned a profit of USD 6 million, with an average rate of Rs. 84.50. At the year end the closing rate was Rs. 86.00, and closing net assets were USD 46 million.

USD millionRateRs. crore
Opening net assets4083.00332.00
Profit for the year684.50 (average)50.70
Sub-total46382.70
Closing net assets at closing rate4686.00395.60
Exchange difference to OCI12.90

The Rs. 12.90 crore arises entirely from translating the same USD 46 million of net assets at Rs. 86.00 rather than at the mixture of Rs. 83.00 and Rs. 84.50 used for the opening balance and the profit. It goes to OCI and accumulates in the translation reserve.


The 2023 Amendments: Lack of Exchangeability

In August 2023 the IASB amended IAS 21 to address a gap the standard had not previously covered: what an entity should do when a currency is not exchangeable into another currency.

The amendments are effective for annual reporting periods beginning on or after 1 January 2025, with early application permitted, and are relevant to entities with transactions or operations in a currency that is not exchangeable into another currency at a measurement date for a specified purpose.

Two elements were added. First, a framework for assessing whether a currency is exchangeable, based on whether an entity is able to obtain the other currency within a normal administrative delay and through a market or exchange mechanism that creates enforceable rights and obligations. Second, a requirement, where exchangeability is lacking, to estimate the spot exchange rate at the measurement date, being the rate that would have applied in an orderly exchange transaction between market participants.

Substantial disclosure requirements accompany the amendments, covering the nature and financial effects of the lack of exchangeability, the spot rate used, the estimation process, and the risks to which the entity is exposed.

The amendments matter for entities operating in economies with capital controls or restricted currency access, and for groups consolidating subsidiaries in such economies.


The Hyperinflationary Presentation Currency Amendments

A further amendment to IAS 21 addresses translation to a hyperinflationary presentation currency, following an exposure draft issued in July 2024.

The situation addressed is a specific one: a reporting entity or its foreign operation has a functional currency of a non-hyperinflationary economy, while the reporting entity's presentation currency is the currency of a hyperinflationary economy.

The amendment requires the entity to translate amounts from a functional currency of a non-hyperinflationary economy to a presentation currency of a hyperinflationary economy using the closing rate at the date of the most recent statement of financial position.

The IASB's reasoning was that an entity applying the amendment expresses all amounts subject to translation in terms of a current measuring unit, which removes the need to separately consider the applicability of IAS 29, covered in Post 79.

Lack of exchangeability amendmentsEffective from 1 January 2025Corresponding amendment notified for Indian application

The D13AA option is the substantive Indian difference and it exists for a specific historical reason. Under the previous Indian framework, companies could capitalise exchange differences on long-term foreign currency monetary items into the cost of related assets or amortise them over the item's remaining life, rather than recognising them immediately in profit or loss. Indian companies with substantial external commercial borrowings had built that treatment into their reported results, and requiring immediate recognition on transition would have produced large one-off charges.

The relief is transitional and closing. It applies only to items existing at the date of transition to Ind AS, and only until those items are settled. It is not available for borrowings taken on after transition, and the population of companies still applying it shrinks each year as the legacy borrowings mature.


What Big 4 Auditors Focus On

Functional currency determination for foreign subsidiaries. Auditors test the assessment for each entity in the group, particularly where a subsidiary's local currency differs from the currency in which it prices, borrows, and holds cash. Assuming local currency without performing the assessment is a recurring finding, and an incorrect determination affects every subsequent number.

Monetary and non-monetary classification. Auditors test the classification of less obvious items: advance payments and receipts, deposits, provisions, contract assets and liabilities, and deferred consideration. Retranslating a non-monetary item, or failing to retranslate a monetary one, produces errors that compound across periods.

Rates used for non-monetary items measured at fair value. Auditors verify that the rate applied is the rate on the date fair value was determined, not the closing rate and not the original transaction rate.

Net investment classification of intragroup balances. Auditors test whether balances treated as part of the net investment genuinely meet the condition that settlement is neither planned nor likely in the foreseeable future, since misclassification moves exchange differences between profit or loss and OCI.

The follow-the-item principle for non-monetary items. Auditors verify that exchange components on revalued assets and other items with gains or losses in OCI have been recognised in OCI rather than profit or loss.

Translation reserve computation and recycling. Auditors recalculate the translation reserve movement and, on disposal of a foreign operation, verify that the cumulative amount relating to that operation has been reclassified to profit or loss.

Lack of exchangeability assessment. For groups with operations in economies with currency restrictions, auditors test whether the exchangeability assessment has been performed and, where exchangeability is lacking, whether the estimated spot rate and the associated disclosures meet the amended requirements.


Dip IFRS Exam Angle

IAS 21 is examined consistently, usually combining a classification question with a translation calculation.

Most tested areas:

Determining functional currency from a described set of facts, applying primary indicators first.

Classifying items as monetary or non-monetary, with advance consideration and prepayments as frequent test items.

Applying the three translation rules at the reporting date and calculating the resulting exchange differences.

Determining whether an exchange difference goes to profit or loss or to OCI, including the net investment case and the follow-the-item principle.

Translating a foreign operation for consolidation and deriving the translation reserve movement.

Common traps:

Treating functional currency as an accounting policy choice. It is a matter of fact.

Retranslating non-monetary items at the closing rate. Items at historical cost stay at the historical rate.

Treating advance consideration as monetary. A prepayment confers a right to goods or services, not to currency.

Recognising exchange differences on a net investment monetary item in profit or loss in the consolidated financial statements. They go to OCI on consolidation, though they remain in profit or loss in the individual statements.

Translating income and expenses of a foreign operation at the closing rate. Transaction date rates, or an average as an approximation, apply.

Restating prior periods when the functional currency changes. The change is applied prospectively.

Forgetting to recycle the translation reserve to profit or loss on disposal of a foreign operation.


FAQ

Can a company choose its functional currency to reduce reported volatility?

No. Functional currency is determined from the facts of the entity's primary economic environment. Presentation currency is a free choice, but changing presentation currency does not change measurement; it only changes display.

Why is a prepayment non-monetary when it was paid in cash?

Because what the entity holds afterwards is a right to receive goods or services, not a right to receive a fixed or determinable number of currency units. The cash has already gone. The remaining asset does not carry currency risk in the IAS 21 sense.

Does an exchange difference on a right-of-use asset arise?

No. The right-of-use asset is non-monetary and is measured at historical cost in the functional currency, so it is not retranslated. The lease liability is monetary and is retranslated at each reporting date, producing exchange differences in profit or loss with no offsetting movement on the asset.

When does a monetary item become part of a net investment in a foreign operation?

When settlement is neither planned nor likely to occur in the foreseeable future. The classification affects only the consolidated financial statements, where exchange differences go to OCI; in the individual financial statements of both entities, the differences remain in profit or loss.

What happens to the translation reserve if a foreign subsidiary is partially disposed of but control is retained?

Where control is retained, the transaction is an equity transaction under IFRS 10 and a proportionate share of the cumulative translation reserve is reattributed to non-controlling interests within equity, rather than being reclassified to profit or loss. Reclassification to profit or loss occurs on loss of control.

Why did the IASB need to amend IAS 21 for lack of exchangeability?

Because the standard assumed a spot rate would always be observable and did not address what to do when a currency cannot be exchanged at all. Entities operating in economies with capital controls were applying inconsistent approaches, and the 2023 amendments introduced both an assessment framework and an estimation requirement, with extensive disclosure.
