Accounting in Hyperinflationary Economies (IAS 29): How to Adjust Statements to Maintain Value?
When inflation reaches “hyper” levels, historical statements become less capable of explaining reality:
the same pound today is not the same as it was months ago, causing nominal increases to mix with real increases and eroding comparability.
Here, the Hyperinflation Standard (IAS 29) steps in to restore meaning to figures by
restating financial statements using a general price index and measuring purchasing power losses.

1) What is the Hyperinflation Standard (IAS 29)?
IAS 29 aims to make financial statements economically meaningful when a currency rapidly loses its purchasing power. In this situation, “historical” figures can be misleading: assets recorded at old costs and revenues appearing high while, in reality, a large portion is just the effect of inflation (nominal increase).
The solution in IAS 29 is to restate financial statements so they are presented in a “current measuring unit” using a general price index, while showing the effect of inflation on monetary items through purchasing power gains/losses.
2) When is an economy considered hyperinflationary?
Judgment does not rely on a single figure; rather on a set of indications (quantitative and qualitative). The practical idea: when holding cash becomes a significant risk, and daily transactions are priced “anticipating inflation” rather than based on stable costs.
| Indicator | How it appears in reality? | Why it matters for accounting? |
|---|---|---|
| Rapid erosion of purchasing power | Prices change frequently over short periods | Historical figures lose comparative meaning. |
| Preference for non-monetary assets | Individuals/companies convert cash to goods/currencies | Holding cash leads to purchasing power losses. |
| Pricing linked to foreign currency | Contracts are linked to USD or a price index | Affects recognition, disclosure, and risks. |
| Very high nominal interest rates | Financing costs rise, liquidity pressures increase | Dual impact on statements and financing. |
3) Core Idea: Current Measuring Unit
The fundamental problem in hyperinflation is that the measuring unit itself changes. Traditional accounting implicitly assumes currency is “relatively stable,” while in hyperinflation, comparing two figures over time becomes unfair because they were effectively measured by two different units.
4) Monetary vs Non-monetary (Why does it matter?)
To understand IAS 29 quickly, remember this rule: Monetary items are not restated by the index (as they will be received/paid in fixed “nominal” units), but they result in an inflation effect recorded as purchasing power loss or gain. Non-monetary items are usually restated by the index to present “current” values for comparison.
| Type | Examples | What do we do in IAS 29? | Logic |
|---|---|---|---|
| Monetary | Cash, receivables, loans, bonds | Not restated using index | Nominal value is fixed… but purchasing power changes. |
| Non-monetary | Inventory, fixed assets, certain investments, equity | Restated using index (based on acquisition date) | We need to unify measuring units to “current”. |
5) Steps to restate financial statements under IAS 29
The core of restating financial statements is using the price index to convert figures from “historical amounts” to “amounts in a current measuring unit”. Practically, you will work on 3 paths: Balance Sheet, Income Statement, and Equity/Disclosures.
5.1 Selecting the appropriate Index
- A general index with wide coverage (not a narrow sectoral index).
- Reliable and consistent source over time.
- Compliance with regulatory/audit requirements.
5.2 Restating non-monetary items in the Balance Sheet
- Identify non-monetary items measured at historical cost (e.g., fixed assets, inventory, equity).
- For each item: use a restatement factor based on (closing index ÷ recognition date index).
- Record the restatement difference within the required treatments (per standard and presentation).
5.3 Restating Income Statement elements
Revenues and expenses are usually restated to “period-end measuring units”. The goal: for margins and profit to be “measured” by the same unit used in the Balance Sheet.

5.4 Equity
Equity (capital, reserves, retained earnings) is affected by restatement because it represents cumulative value over years. The goal is to restate it to current measuring units to enable fair comparison and true understanding of value.
6) Purchasing Power Loss: Simple understanding and measurement
In inflation, holding cash (or a net positive monetary position) usually means a loss of purchasing power: the same cash buys less later. This idea is translated in IAS 29 via the purchasing power gain/loss (Monetary Gain/Loss) line item.
- Net positive monetary position (Cash + Receivables − Monetary Liabilities) → usually a purchasing power loss during inflation.
- Net negative monetary position (Higher monetary liabilities) → may generate a purchasing power gain because you settle obligations with “real” lower value later.
Practically, accurate measurement requires tracking monetary items during the period, but you can start with a simplified estimate based on average net monetary position and the inflation factor (change in index).
7) Numerical Example to apply the concept
The following example aims to clarify the trend (not replace a detailed model). Assume the general price index rose during the year from 100 to 160.
| Item | Type | Historical Value | Recognition Index | Closing Index | Restated Value (Approx) |
|---|---|---|---|---|---|
| Machine/Fixed Asset | Non-monetary | 1,000,000 | 110 | 160 | 1,454,545 |
| Closing Inventory | Non-monetary | 500,000 | 140 | 160 | 571,429 |
| Average Net Monetary Position | Monetary | +300,000 | — | — | Purchasing power loss (estimated) based on index change |
8) Disclosures and Best Practices
IAS 29 success lies in clear disclosure: Which index was used? How was hyperinflation determined? What is the restatement methodology? Investors and management want to understand “what changed and why”.
- Stating the Index used, its source, and measurement period.
- Explaining the professional judgment used to determine hyperinflation.
- Clarifying the methodology for restating non-monetary items and the Income Statement.
- Presenting the purchasing power loss impact and how it was calculated.
9) Impact of IAS 29 on Financial Analysis and Decisions
After restating financial statements, ratio readings will change: Margins, ROA, ROE, leverage ratios, inventory turnover, and working capital. The reason isn’t necessarily “performance change,” but a change in measuring units and the comparative base.
Often, the real pressure appears in monetary items (liquidity, collection, and financing). If your activity involves imports/exports or strong exchange rate exposure, risk management becomes part of the story:
10) Practical Tools and Useful Models
In periods of high inflation, payment behaviors change and credit risks rise, making receivable tracking and credit estimates more sensitive. If you are building ECL estimates or forecast models, these ready-made templates will be useful:
11) Quick Checklist for implementation
- Verify hyperinflation indicators and document professional judgment.
- Select an appropriate general index and agree on its source internally.
- Classify Balance Sheet items into monetary and non-monetary (with recognition dates).
- Restate non-monetary items using price index (Period-end ÷ Recognition date).
- Restate the Income Statement to the period-end measuring unit.
- Calculate/estimate purchasing power loss for monetary items and clarify methodology.
- Review comparison and disclosure consistency so statements are understandable and comparable.
12) Frequently Asked Questions
What is the Hyperinflation Standard (IAS 29) in brief?
It is a standard requiring the restatement of statements when an entity operates in a hyperinflationary economy to make numbers comparable and meaningful, by adjusting items using a general price index and recognizing purchasing power gains/losses.
When do we apply IAS 29?
When hyperinflation indicators (quantitative and qualitative) are present, making historical statements unrepresentative without restatement, considering regulatory framework requirements.
What is the difference between monetary and non-monetary items?
Monetary items (cash, receivables, loans) are not restated by index but generate a power effect. Non-monetary items (inventory, fixed assets, equity) are restated to maintain value and comparative meaning.
How are purchasing power losses calculated?
Based on net monetary position during the period and the general price index change. A net positive position usually leads to a loss, while a net negative position may generate a gain.
Does IAS 29 affect financial analysis?
Yes, because it changes measurement bases and restates items, altering ratios. The key is comparing consistent periods (all restated) before interpreting trends.
13) Conclusion
The Hyperinflation Standard (IAS 29) is not “extra complexity,” but a lifeline for statement meaning when currency becomes unstable. By applying statement restatement using a general price index and understanding the effect on monetary items via purchasing power losses, you get fairer, more comparable statements—and more accurate analysis and decisions.
