Where a central bank neither floats a currency nor pegs it to a named anchor, the official rate has to come from somewhere else. In Algeria it comes from a model: the International Monetary Fund records that the Bank of Algeria targets a real effective exchange rate derived from an econometric model taking in variables such as the oil price and the budget deficit. The Fund classifies the arrangement as de jure managed floating and de facto crawl-like, and records a parallel market premium that widened from 50 to 70 per cent over the two years to its 2025 consultation.
Most published exchange rates are observations. Somebody traded, and the number records it. A smaller group are not observations at all: they are outputs, produced by a process, and the difference determines what the number can be used for.
Key Takeaways
- Algeria's central bank targets a real effective exchange rate derived from an econometric model, on the Fund's account.
- The model's inputs include the oil price and the budget deficit, which are not things a currency market trades.
- The Fund classifies the arrangement as de jure managed floating and de facto crawl-like.
- A persistent second price, not a narrow spread, is what marks an administered rate: deep markets have narrow spreads too.
- The parallel premium widened from 50 to 70 per cent over the two years to the 2025 consultation.
The three places an official rate comes from
One of three places, and they are not interchangeable.
A floating currency's official rate is a summary of trading. Somebody bought and somebody sold, and the published figure describes what happened, usually as a weighted average over a defined window.
A pegged currency's official rate is a commitment. It is whatever the authority has said it will hold, and holding it is the work; the number itself was decided once and is then defended.
The third case is the one that gets least attention. Where a central bank neither leaves the rate to a market nor fixes it to a named anchor, the rate has to be produced. The International Monetary Fund's record of Algeria describes exactly that: the Bank of Algeria targets a real effective exchange rate that is derived from an econometric model considering various variables, and the Fund gives the oil price and the budget deficit as examples of them.
Read that carefully, because it is a stronger statement than "managed". The target is not a level against the US dollar or the euro. It is a modelled measure of competitiveness, and the inputs include a commodity price and a fiscal aggregate, neither of which is something a foreign exchange market prices.
The measure Algeria targets
A measure of relative prices, not a rate anybody transacts at.
An effective exchange rate is a weighted average of a currency's value against the currencies of the countries it trades with, with the weights reflecting how much trade goes each way. The real version adjusts that average for differences in inflation, so it describes whether a country's goods are becoming more or less expensive relative to its partners' goods.
That makes it a competitiveness measure. A country targeting one is aiming at a relationship between two sets of prices rather than at a screen. It is a perfectly reasonable thing to aim at, and the Fund's own external assessment for Algeria uses the same measure from the other side, putting the real effective rate at a moderate overvaluation of 6.3 per cent in 2024.
The consequence is that the number on the board is downstream of a judgement about competitiveness, and the judgement is made using inputs that have nothing to do with anybody wanting to buy dinars today. The Fund's classification captures the result: managed floating in law, crawl-like in observed behaviour.
Telling an administered rate from a traded one
By whether a second price persists, not by the width of the spread.
The spread is the test most people reach for, and it points the wrong way. A narrow gap between buying and selling prices is the mark of a deep and liquid market: the most heavily traded currency pairs in the world quote the tightest spreads there are, precisely because the risk of holding a position between the two sides of a trade is small and briefly held. A narrow spread on its own tells you nothing about whether a number was traded or set.
What does distinguish them is what happens when a second price appears. In a market that clears, two prices for the same thing cannot both survive: somebody buys at the lower and sells at the higher until they meet. Where the official rate is administered and demand exceeds supply at it, the second price is not competed away, because the first one is not available in the quantity people want. A second price that persists for years is therefore the diagnostic, and its distance from the official rate measures how much is unavailable at that rate.
For completeness, the Fund does record the Bank of Algeria's transactions in foreign exchange as carrying a very narrow spread, giving 0.015 dinars on US dollar transactions as its example. In this case that margin is administrative rather than competitive, but only because everything else about the arrangement establishes that first.
| Signal | A traded rate | An administered rate |
|---|---|---|
| What a second price means | An arbitrage, and it closes | A separate market, and it can persist |
| Where the number comes from | Recorded transactions | A target or a model output |
| What moves it | Order flow | A decision, or a model input |
| Buy and sell prices | Narrow where the market is deep | Narrow because they were set |
The first row is the one that does the work, and the last is there as a warning: a narrow spread appears in both columns for opposite reasons, so it separates nothing on its own. That distinction is why the mid-market rate on a converter is a different kind of object depending on which column a currency sits in.
What the gap to the other price measures
The distance between the administered number and what people are paying.
The Fund records Algeria's parallel market premium as having widened from 50 to 70 per cent over the two years to its 2025 consultation, and identifies three drivers: expansionary fiscal policy, tight restrictions on some imports and some foreign exchange transactions, and declining remittances.
Two of those three are about supply rather than about the currency's value. Restrictions on imports and on foreign exchange transactions reduce the amount of foreign currency that can be obtained through the official channel, and declining remittances reduce the amount arriving in the first place. Demand that cannot be met at the official price does not evaporate; it goes somewhere else and pays what is asked.
That is why the premium is better read as a measure of rationing than as a verdict on the currency. It says how much foreign exchange is unavailable at the official rate, expressed as a price.
The policy response
More supply through the official channel, and, from the Fund, more flexibility in the rate.
The Fund's recommendation is decisive measures to increase foreign exchange availability for current transactions, noting that greater exchange rate flexibility would also help reduce the spread between the official and parallel rates. It also reminds the authorities of the obligation under Article VIII of the Fund's articles to ensure sufficient foreign exchange is available for current international transactions.
The authorities' own position, as the Fund records it, is that their current monetary and exchange rate policies are appropriate, and that they are taking steps to reduce parallel market activity. Among those steps are increases in the amounts residents may obtain officially through the allowance system, which the AUD to DZD page sets out. They work on one principle: meet at the official price demand that would otherwise be met at the other one.
For anyone converting from Australia, the practical reading is short. The Australian dollar to Algerian dinar rate is a real number and it is the rate at which official transactions are done. It is not a market clearing price, and in a country with a premium of this size the two are answering different questions.

Common questions
How is Algeria's official exchange rate decided?
By targeting a modelled outcome rather than by clearing a market. The International Monetary Fund records that the Bank of Algeria targets a real effective exchange rate derived from an econometric model that considers various variables, giving the oil price and the budget deficit as examples. The Fund classifies the arrangement as de jure managed floating and de facto crawl-like.
What is a real effective exchange rate?
A weighted average of a currency's value against the currencies of its trading partners, adjusted for differences in inflation. It is a measure of competitiveness rather than a price anybody transacts at, so a country targeting one is aiming at a relationship between its own prices and its partners' prices rather than at a number on a screen.
How can you tell an administered rate from a market one?
Not by the spread, which is the test people reach for and it does not work: the deepest markets in the world quote the narrowest spreads of all. The reliable sign is a second price that persists. In a market that clears, two prices for the same thing are an arbitrage and they converge. Where an official rate is administered and demand exceeds supply at it, a second price can sit alongside it for years, and its distance from the official one is a measure of how much is unavailable at the official price.
What does the gap to the parallel rate measure?
The distance between the administered price and the price at which foreign currency is actually changing hands. The Fund records Algeria's parallel market premium as having widened from 50 to 70 per cent over the two years to its 2025 consultation, and attributes the widening to expansionary fiscal policy, tight restrictions on some imports and some foreign exchange transactions, and declining remittances.
What is being done about it?
Supply, mainly. The Fund's recommendation is decisive measures to increase foreign exchange availability for current transactions, and greater exchange rate flexibility to reduce the spread between the official and parallel rates. It also records the authorities as considering their current policies appropriate and as having increased the amounts residents may obtain officially, in order to reduce demand reaching the parallel market.
