The Most Liquid Currency Pairs

The Most Liquid Currency Pairs

Liquidity – the ability of assets to be sold quickly at the price closest to the market one.

However, one definition is not enough to answer the question «What currency pair is the most liquid?» since the liquidity must somehow be measured.

Ideally, we must calculate the total volume of all pending orders for a specific currency pair and compare it with the volume of the rest pairs. By doing so we can rank the currency pairs from the most liquid to the most illiquid ones.

Nevertheless, we are unable to calculate these volumes due to the fact that the Forex market has no single center, and God knows how many open orders are currently there indeed.

On the other hand, we have some data on the activity of different currency pairs, namely, the percentage of the total volume for every pair.

Thus, if we take the entire volume of transactions in the Forex market as 100%, each pair will constitute a certain share in the total volume.

The Most Liquid Currency Pairs

We obtained a chart displaying the share of each currency pair as of January 2018 for you:

Note: We cannot guarantee that this chart is 100% accurate in terms of the current market situation, but the possible error does not exceed 5-10%.

So, the most liquid currency pair is EURUSD, which accounts for more than 20% of the total volume of transactions in the Forex market.

The second most liquid forex pair is USDJPY with a share of 14%.

The third most liquid is AUDUSD (9%).

Information on other currency pairs can be found on this chart above.

By the way, the least liquid currency pair on the above chart is GBP/CHF. The XAG/USD is not a currency pair.

Of course there are other a lot of other pairs, mainly exotic ones, but nobody knows which one of them is least liquid. Probably they all are illiquid comparing to majors.

What makes liquid pairs interesting for us?

If you take interest in the most liquid currencies, it matters to you. Indeed, the quality of orders execution is highly dependent on the liquidity and commission costs.

More liquid pairs are characterized by:

  • rare slippage;
  • lower spread.
  • fast execution of orders.

This is the reason why many traders prefer trading in more liquid currency pairs only, and some of them «get stuck to» EURUSD and don’t even consider other pairs for trading.

Truly speaking, the difference in liquidity among the seven major pairs is not substantial enough to confine yourself to trading in one of them only.

By the way, now that we're talking about the major currency pairs… Not the pairs themselves have the liquidity, but the currencies constituting the pairs.

Put the phrase «currency pair» in the definition of the liquidity and you’ll get: “Liquidity is the ability of a currency pair to be sold quickly…". However, we don't sell a currency pair itself but sell/buy a specific currency. Accordingly, the liquidity of a currency pair derives from the liquidity of the currencies making it up.
