G10 Currencies: The List, the Mismatch and What It Means

The G10 currency list holds ten currencies. The Group of Ten holds eleven countries. Three of the ten currencies belong to countries that are not members of it at all.

None of that is a trick question. It is what happens when a label outlives the arrangement that produced it, and knowing which of the two a page is talking about settles most of the confusion around the term.

The Ten Currencies on the List

In everyday market usage the list runs: US dollar, euro, yen, sterling. Then the Canadian dollar, the Swiss franc and the Swedish krona. Then three more that are the reason this page exists, being the Norwegian krone, the Australian dollar and the New Zealand dollar.

That set is what a dealer means by G10 FX, and it is stable across desks. What it is not is a published list with a custodian, which is the first thing to establish about it and the subject of a later section here.

Read against the country group whose name it borrows, that last trio is the anomaly. Norway, Australia and New Zealand are all on the currency list through their currencies, and not one of the three countries belongs to the Group of Ten.

The Group of Ten Has Eleven Countries

The Group of Ten is an actual institution rather than a market shorthand. In its own account of the period the BIS describes coordinating central bank responses through it, and names who took part. Five of those participants now share the euro: Italy, Belgium, the Netherlands, Germany and France.

The remaining six kept their own money. They are the United States, Japan, the United Kingdom, Canada and Sweden, together with Switzerland, which the BIS records as an associated member rather than a full one.

Count that and the total is eleven. The name records how many the group had when it formed, not how many it ended with, and it was never renamed.

The group was built for a monetary purpose, not a trading one. Its work through the BIS in the 1960s ran to a common gold pool, a central bank currency swap network and repeated joint support operations for individual currencies.

So a reader who finds the phrase in a policy document and the phrase on a dealing screen is looking at two different objects that happen to share four characters.

The name has survived because nothing depends on it being accurate. There is no register to amend, no members to consult and no consequence to leaving it, which is the ordinary reason a label outlives its own definition rather than being corrected.

Why the Euro Broke the Arithmetic

Five members of the group no longer issue a currency of their own. Belgium, France, Germany, Italy and the Netherlands all use the euro, so five memberships collapse into one entry on any currency list built from the group.

Work it through and the group yields seven currencies: the US dollar, the Canadian dollar, the yen, sterling, the Swedish krona, the Swiss franc and the euro that stands in for the other five.

The convention then fills the three empty places from outside the membership altogether, taking in the krone of Norway and the dollars of Australia and New Zealand. That is where the arithmetic stops following the group, and ten was preserved as a number after it had stopped describing anything.

This is a different failure from the one our page on major and minor pairs examines, where the classification has no author at all. Here there was an author, and the list has drifted away from what the author actually defined.

Who Actually Publishes This List, and Who Does Not

The BIS publishes the country group. The IMF arrangements that created it are documented. Neither publishes a list of ten currencies called the G10, and no central bank maintains one.

The practical consequence is that nobody can be wrong about it in a formal sense, and that is why the edges move. A page listing eleven entries by adding the renminbi, or nine by dropping the krone, is not contradicting a standard, because no standard exists to contradict.

Where a definition does exist, it is worth using instead. The dollar index basket has a named calculator, a published weighting and a rule for changing it, and that is the difference between an index and a convention.

G10, G7 and the Majors Are Three Different Groupings

Three labels circulate for overlapping sets, and they answer different questions.

G7 is political and economic, covering Canada, France, Germany, Italy, Japan, the United Kingdom and the United States. Applied to currencies it produces five: the euro replaces three of the seven, and the remaining four issue their own.

The majors, as brokers use the term, is a trading classification about liquidity and spread rather than about membership of anything, and it usually names pairs rather than currencies.

G10 sits between them, taking its name from an institution and its contents from custom. When a report says G10 currencies it means the ten above, and when it says G10 countries it means the eleven, and the reader has to decide which from context because the words do not distinguish them.

The overlap between the three is what makes them easy to confuse. Every G7 currency is on the G10 list, and every G10 currency appears somewhere in a broker majors table, so a claim made about one grouping will usually look true of the others until a case arrives where they diverge. The krone, the krona and the New Zealand dollar are where that happens, and they are on the G10 list precisely because it is the widest of the three.

What the Ten Share: Turnover, Settlement and Free Floating

If the list is not a membership, the reasonable next question is whether it at least tracks something measurable. Two candidates are usually offered, and both fall short.

The first is turnover. The BIS Triennial Central Bank Survey put global over-the-counter FX turnover at 9.6 trillion US dollars a day in April 2025, up 28 per cent from 7.5 trillion three years earlier, and gave the shares of individual currencies on one side of a trade.

The last two rows are the answer. A currency that is on neither the list nor the membership traded on more sides than one that is on both, so the ten cannot be described as the ten most traded currencies without contradicting the survey.

The second candidate is settlement. CLS states that it settles more than 8 trillion US dollars of payments a day in 18 of the most actively traded currencies, and its published currency page includes the Hungarian forint, the South African rand, the Singapore dollar and the Hong Kong dollar alongside the ten. Eligibility there is a wider set, so it does not define this one either.

What genuinely holds across the ten is that each floats, each has a deep forward and options market, and none is administered against a peg, which is the distinction our page on pegged currency regimes works through.

That shared property is worth stating in what it delivers rather than as a description. A freely floating currency with a deep forward market can be hedged out to a distant date at a price set by interest rate differentials, and it can be traded in size without the quote widening at every clip.

Those two things are what a desk is buying when it treats a currency as developed-market, and they are what an administered currency cannot offer at any volume. It is also the property that survives when the label is questioned, which makes it the one worth carrying away.

What the Label Means When a Bank or Broker Uses It

In practice G10 FX is a desk boundary. It marks the currencies a bank runs on its main developed-markets book, as opposed to the emerging-markets book, and it sets which pricing, hours and credit arrangements apply.

For a retail trader the label carries no entitlement, in the same way that the safe haven currencies label describes past behaviour rather than a guarantee. It does not fix a spread, guarantee an execution standard or mean a broker offers all ten, and two firms using the term may list different instruments behind it.

The check is the instrument list, not the label. A firm advertising G10 coverage may quote eight of the ten, or quote the krone and the krona only against the euro and the dollar, and the answer sits in the contract specification rather than in the marketing.

Its usefulness is as a rough proxy for where the deepest two-way pricing sits during the sessions those currencies belong to, which is why it reads more naturally beside our page on session hours than beside any regulatory term.

Where the Grouping Stops Being Useful

The label stops helping the moment it is used to predict behaviour. The ten do not move together: they contain commodity currencies, safe-haven currencies and the currency everything else is quoted against, and their relationships shift with conditions in the way our page on currency correlation describes.

It also stops helping for anything that depends on policy. Rate decisions inside the ten are made by separate central banks with separate mandates, and reading a stance for one from a grouping is the mistake our page on central bank stance is written against.

And it stops helping as a filter for what to trade. Ten currencies produce forty-five possible pairs, of which a broker will quote a fraction, and the ones with the tightest pricing are decided by which pairs the market actually trades rather than by which currencies share a label.

Used for what it is, a shorthand for a set of freely floating, deeply traded currencies, the term is convenient. Used as a ranking, a standard or a membership, it will mislead, because it is none of those things.

Frequently Asked Questions

Which currencies are on the G10 list?

US dollar, euro, yen and sterling, then the Canadian dollar, Swiss franc and Swedish krona, then the Norwegian krone, Australian dollar and New Zealand dollar. The set is a market convention rather than a published standard, so no institution maintains it.

Are the G10 currencies the same as the G10 countries?

No. The BIS records eleven participants, of which five now share the euro, namely Italy, Belgium, the Netherlands, Germany and France, while the United States, Japan, the United Kingdom, Canada and Sweden keep their own, and Switzerland is listed as an associated member. Australia, New Zealand and Norway appear on the currency list without being members at all.

How do the G10 currencies differ from the G7 currencies?

G7 is a smaller and separate grouping of seven countries, and because the euro covers three of them it yields five currencies rather than seven. The G10 currency list is longer and includes currencies from countries in neither group.

Why are the Australian dollar and the New Zealand dollar counted as G10 currencies?

By convention rather than by membership. Once the euro absorbed the currencies of five member countries the list built from the group ran short, and the two, along with the Norwegian krone, filled the remaining places because they float freely and trade deeply.

What does a bank mean by G10 FX?

The developed-markets side of a foreign exchange desk, as opposed to emerging markets. It describes which book a currency sits on and which pricing and credit arrangements apply, and it confers nothing on a retail account.
