Hedging Foreign Currency Exposures and Hyperinflation in ACCA SBR

Updated 11 October 2026 · Fact-checked

A net investment hedge uses a hedging instrument, such as a foreign loan, to offset exchange differences on a foreign operation's net assets, with effective gains and losses held in OCI. IAS 29 restates the financial statements of a hyperinflationary entity into a current measuring unit before translation at the closing rate.

Understand Hedging Foreign Currency Exposures and Hyperinflation

A parent with a foreign subsidiary has an exposure. The subsidiary's net assets are in a foreign currency. When you translate them at the closing rate under IAS 21, exchange differences arise each year. These go to other comprehensive income (OCI) and sit in a translation reserve. They do not hit profit or loss until disposal.

A net investment hedge protects against this. The parent might borrow in the subsidiary's currency. If the currency weakens, the net assets fall in value, but the loan falls in value too. The loan's exchange gain is an offsetting amount. Without hedge accounting, the loan gain would go to profit or loss while the matching loss on the net assets goes to OCI. That creates a mismatch. Hedge accounting removes it.

Under IFRS 9, the hedge of a net investment in a foreign operation is accounted for like a cash flow hedge. The effective portion is the part of the gain or loss on the hedging instrument that offsets the change in the hedged net assets. It goes to OCI. Any excess is ineffective and goes to profit or loss. On disposal of the foreign operation, both the cumulative translation difference and the cumulative hedge gain or loss in equity are reclassified to profit or loss. The hedged item is the designated amount of the net assets of the foreign operation, including goodwill, not profit. That amount may be all of the net assets or only part of them, so always compare the instrument with the designated amount, not with the total net assets. Goodwill is part of the net investment because it is treated as an asset of the foreign operation under IAS 21.

To qualify, you need formal designation and documentation at inception, an economic relationship between hedged item and instrument, credit risk that does not dominate, and a hedge ratio that reflects the risk management actually used. The hedged risk is the foreign currency risk between the functional currency of the foreign operation and the functional currency of the parent. The hedging instrument can be a derivative or a non-derivative such as a foreign currency loan. The hedge can be held by any entity in the group, subject to the conditions in IFRS 9.

Hyperinflation is a different problem. IAS 21 normally translates at closing rates. In a hyperinflationary economy, money loses value so fast that historical-cost figures become meaningless. IAS 29 requires the entity to restate its statements into the measuring unit current at the reporting date, using a general price index. Then you translate the restated figures at the closing rate. IAS 29 does not give a fixed inflation rate that defines hyperinflation. It lists indicators, and one of them is cumulative inflation over three years approaching or exceeding 100%.

Key rules to remember

Net investment hedge: effective portion: OCI (hedge reserve) = the lower, in absolute terms, of the cumulative gain or loss on the instrument and the cumulative change in value of the designated hedged amount of net assets; The hedged amount may be only part of the net assets, so do not compare with the total net assets difference. Any excess gain or loss on the instrument is ineffective and goes to profit or loss.
Foreign loan hedging net assets: exchange difference: Loan exchange difference = Loan in foreign currency × (closing rate − opening rate) using the quoted rate as foreign currency per parent currency unit, so divide, do not multiply; If the rate is quoted as foreign units per $1, the loan in foreign units is divided by the rate. A weaker foreign currency (higher units per $) lowers the dollar value of the loan, giving a gain.
Translation of net assets under IAS 21: Exchange difference in OCI = closing net assets at closing rate − (opening net assets at opening rate + profit at average rate); This formula applies only to a foreign operation that is not hyperinflationary. For a hyperinflationary subsidiary, translate the restated profit and all other current-year amounts at the closing rate (where the presentation currency is not hyperinflationary). Include goodwill in net assets for a foreign operation. Adjust for dividends at the rate on the date paid.
Disposal reclassification: Reclassify to profit or loss = cumulative translation reserve + cumulative net investment hedge reserve (effective portion); Reclassification is made on disposal of the foreign operation, as a reclassification adjustment.
IAS 29 restatement of non-monetary items: Restated amount = historical cost × (price index at reporting date ÷ price index at date of acquisition or revaluation); Monetary items are not restated. Non-monetary items carried at historical cost are restated. Items already at current value at the reporting date are not restated.
IAS 29 net monetary position: Gain or loss on net monetary position goes to profit or loss; net monetary liabilities give a gain and net monetary assets give a loss during inflation; Holding cash loses purchasing power. Owing money gains because the debt is repaid in cheaper units. Income statement items are restated using the index from the date of the transaction, and equity components from the date they were contributed or arose.
Translation of hyperinflationary subsidiary: Restate under IAS 29 first, then translate the current-year restated amounts at the closing rate. Comparatives are the prior-year presented amounts, unchanged (if the presentation currency is not hyperinflationary); Where the presentation currency is not that of a hyperinflationary economy, comparatives are the amounts presented in the prior year, not restated further and not translated at the current closing rate.

How to solve Hedging Foreign Currency Exposures and Hyperinflation questions

Use this order for any question on hedging a foreign operation or a hyperinflationary subsidiary. It keeps you on the marking scheme and stops you mixing up the two standards.

1Identify the issue: is it a hedge of a foreign operation, a hyperinflationary subsidiary, or both? Look for words such as loan in the subsidiary's currency, designated, or inflation index.
2For a hedge, check the criteria: formal designation and documentation, economic relationship, credit risk not dominant, sensible hedge ratio. State which are met in the scenario.
3Translate the foreign operation's net assets at opening and closing rates, including goodwill, and find the exchange difference on the net investment.
4Calculate the exchange difference on the hedging instrument. Be careful with the direction of the rate quote.
5Compare the two amounts. Put the effective portion in OCI (hedge reserve) and the excess in profit or loss. Show the reserve and the translation reserve separately.
6For hyperinflation, confirm the economy is hyperinflationary using the IAS 29 indicators, then restate non-monetary items using the price index. Do not restate monetary items.
7Calculate the net monetary gain or loss for profit or loss, then translate the restated figures at the closing rate.
8Conclude with the effect on group profit, OCI and equity, and add a comment on judgement, such as whether the economy qualifies or whether the hedge is documented.

Quickest way: Four-line check for hedge or hyperinflation questions

When to use it: Use this when time is short and you need a reliable skeleton answer with the right numbers in the right place.

Write one line naming the standard: IFRS 9 and IAS 21 for the net investment hedge, IAS 29 then IAS 21 for hyperinflation.
Do the numbers on two lines. Put the change in value of the designated hedged amount of net assets and the instrument's exchange difference side by side. Take the lower in absolute terms as the effective portion for the OCI hedge reserve.
Post the entries: translation difference to OCI, effective hedge gain or loss to OCI, excess to profit or loss. For hyperinflation, index non-monetary items, then translate.
Finish with the disposal rule: both reserves are recycled to profit or loss. State it in one sentence, even if not asked, if the scenario mentions a sale.

Common mistakes in Hedging Foreign Currency Exposures and Hyperinflation

Taking the whole gain on the hedging loan to profit or loss.
Students treat a foreign currency loan as an ordinary monetary item under IAS 21, where gains go to profit or loss.
Fix: Check whether the loan is designated as a net investment hedge. If it is, the effective portion goes to OCI. Only the ineffective part goes to profit or loss.
Excluding goodwill from the net investment.
Goodwill feels like a group figure, not a subsidiary figure.
Fix: Under IAS 21, goodwill and fair value adjustments are assets of the foreign operation and are retranslated at the closing rate. Include them in the exposure.
Getting the direction of the exchange gain wrong.
Rates are quoted as foreign units per parent currency unit, and students multiply when they should divide.
Fix: Convert every foreign amount by dividing by the quoted rate. Then compare dollar values at opening and closing to decide gain or loss.
Restating monetary items under IAS 29.
Students apply the index to every line in the statement of financial position.
Fix: Monetary items are already in the current unit. Restate only non-monetary items carried at historical cost. Items at current value need no restatement.
Translating hyperinflationary figures at average rate or before restating.
Students carry over the normal IAS 21 income statement rule.
Fix: Restate first under IAS 29, then translate the current-year restated amounts at the closing rate. Never translate first and restate afterwards. Leave comparatives as the prior-year presented amounts when the presentation currency is not hyperinflationary.
Forgetting reclassification on disposal.
OCI items feel permanent, so students leave them in equity.
Fix: On disposal of the foreign operation, recycle both the translation reserve and the effective hedge reserve to profit or loss.

Worked examples

Example 1

Parent P has the dollar ($) as its functional currency. It owns a subsidiary S whose functional currency is the dinar (D). On 1 January, S's net assets including goodwill are D 10,000,000. The rate is D 2 = $1. P borrows D 4,000,000 on 1 January and designates the loan as a hedge of part of its net investment in S. At 31 December the rate is D 2.5 = $1. Ignore profit and tax. Calculate the exchange difference on the net assets and on the loan, and state the accounting.

Show the solution

Net assets at 1 January: D 10,000,000 ÷ 2 = $5,000,000.
Net assets at 31 December: D 10,000,000 ÷ 2.5 = $4,000,000.
Exchange loss on net assets = $1,000,000, recognised in OCI under IAS 21.
Loan at 1 January: D 4,000,000 ÷ 2 = $2,000,000.
Loan at 31 December: D 4,000,000 ÷ 2.5 = $1,600,000.
Exchange gain on loan = $400,000.
The designated hedged amount is D 4,000,000 of the net assets. That part falls from D 4,000,000 ÷ 2 = $2,000,000 to D 4,000,000 ÷ 2.5 = $1,600,000, a loss of $400,000. The loan gain of $400,000 fully offsets it. The lower of the two, $400,000, is the effective portion.
Record the $1,000,000 loss on the net assets in OCI (translation reserve) and the $400,000 loan gain in OCI (hedge reserve). Show the two reserves separately. The net OCI loss is $1,000,000 − $400,000 = $600,000. Nothing goes to profit or loss.

Answer: The $1,000,000 loss on the net assets goes to the translation reserve in OCI. The $400,000 loan gain fully offsets the loss on the designated D 4,000,000 of net assets, so it goes to the hedge reserve in OCI. The net OCI loss is $600,000 and profit or loss is unaffected.

Example 2

Subsidiary H operates in a hyperinflationary economy. At 31 December its financial statements show cash of H 500,000 and plant of H 2,000,000 at historical cost. The plant was bought when the price index was 100. The index at 31 December is 250. The closing rate is H 50 = $1. Show the plant and cash in the group's financial statements in dollars, assuming the dollar is not hyperinflationary.

Show the solution

Cash is a monetary item. It is not restated: H 500,000.
Plant is a non-monetary item at historical cost. Restate: H 2,000,000 × 250 ÷ 100 = H 5,000,000.
Translate all amounts at the closing rate.
Cash: H 500,000 ÷ 50 = $10,000.
Plant: H 5,000,000 ÷ 50 = $100,000.

Answer: Cash is $10,000 and plant is $100,000. The plant is restated before translation, and the cash is not restated.

Exam tips

Show a short table of opening and closing net assets with the rates used. Markers award method marks even if a rate is misread.
Always say whether the hedge criteria are met. Documentation at inception is a common scenario trap.
State the IAS 29 indicators when asked whether an economy is hyperinflationary, and say that judgement is needed because there is no single rate.
Answer the requirement and tie it to the scenario: say what happens to the group's profit, equity and gearing, not only the double entry.
Use the professional skills marks: explain clearly to a non-specialist why OCI treatment avoids a mismatch.

Practice questions from Foreign transactions and entities

Hedging Foreign Currency Exposures and Hyperinflation: frequently asked questions

What is the difference between IAS 21 and IAS 29 for a hyperinflationary subsidiary?

IAS 21 sets the rules for translating a foreign operation into the presentation currency. IAS 29 comes first. It restates the subsidiary's own statements into the current measuring unit using a price index. Then IAS 21 translation at the closing rate is applied.

Where does a net investment hedge gain go?

The effective portion goes to OCI and is held in a hedge reserve in equity. The ineffective portion goes to profit or loss. Both are reclassified to profit or loss when the foreign operation is disposed of.

Can a foreign currency loan be a hedging instrument?

Yes, for a net investment hedge. IFRS 9 allows non-derivative financial instruments to hedge foreign currency risk. The loan must be formally designated and documented at inception.

Which items are restated under IAS 29?

Non-monetary items carried at historical cost are restated using a general price index. Equity components are restated from the date they were contributed or arose. Income statement items are restated from the date of the transaction. Monetary items are not restated. Items already at current value at the reporting date are not restated either.
