The World’s Most Powerful Reserve Currencies

When we think of network effects, we’re usually thinking of them in the context of technology and Metcalfe’s Law.

Metcalfe’s Law states that the more users that a network has, the more valuable it is to those users. It’s a powerful idea that is exploited by companies like LinkedIn, Airbnb, or Uber — all companies that provide a more beneficial service as their networks gain more nodes.

But network effects don’t apply just to technology and related fields.

In the financial sector, for example, stock exchanges grow in utility when they have more buyers, sellers, and volume. Likewise, in international finance, a currency can become increasingly entrenched when it’s accepted, used, and trusted all over the world.

What’s a Reserve Currency?

Today’s visualization comes to us from HowMuch.net, and it breaks down foreign reserves held by countries — but what is a reserve currency, anyways?

In essence, reserve currencies (i.e. U.S. dollar, pound sterling, euro, etc.) are held on to by central banks for the following major reasons:

To maintain a stable exchange rate for the domestic currency
To ensure liquidity in the case of an economic or political crisis
To provide confidence to international buyers and foreign investors
To fulfill international obligations, such as paying down debt
To diversify central bank portfolios, reducing overall risk

Not surprisingly, central banks benefit the most from stockpiling widely-held reserve currencies such as the U.S. dollar or the euro.

Because these currencies are accepted almost everywhere, they provide third-parties with extra confidence and perceived liquidity. This is a network effect that snowballs from the growing use of a particular reserve currency over others.

Reserve Currencies Over Time

Here is how the usage of reserve currencies has evolved over the last 15 years:

Currency composition of official foreign exchange reserves (2004-2019)
	🇺🇸 U.S. Dollar	🇪🇺 Euro	🇯🇵 Japanese Yen	🇬🇧 Pound Sterling	🌐 Other
2004	65.5%	24.7%	4.3%	3.5%	2.0%
2009	62.1%	27.7%	2.9%	4.3%	3.0%
2014	65.1%	21.2%	3.5%	3.7%	6.5%
2019	61.8%	20.2%	5.3%	4.5%	8.2%

Over this timeframe, there have been small ups and downs in most reserve currencies.

Today, the U.S. dollar is the world’s most powerful reserve currency, making up over 61% of foreign reserves. The dollar gets an extensive network effect from its use abroad, and this translates into several advantages for the multi-trillion dollar U.S. economy.

The euro, yen, and pound sterling are the other mainstay reserve currencies, adding up to roughly 30% of foreign reserves.

Finally, the most peculiar data series above is “Other”, which grew from 2.0% to 8.4% of worldwide foreign reserves over the last 15 years. This bucket includes the Canadian dollar, the Australian dollar, the Swiss franc, and the Chinese renminbi.

Accepted Everywhere?

There have been rumblings in the media for decades now about the rise of the Chinese renminbi as a potential new challenger on the reserve currency front.

While there are still big structural problems that will prevent this from happening as fast as some may expect, the currency is still on the rise internationally.

What will the composition of global foreign reserves look like in another 15 years?

Visualizing the Rise of the U.S. Dollar Since the 19th Century

As the world’s reserve currency, the U.S. dollar made up 58.4% of foreign reserves held by central banks in 2022, falling near 25-year lows.

Today, emerging countries are slowly decoupling from the greenback, with foreign reserves shifting to currencies like the Chinese yuan.

At the same time, the steep appreciation of the U.S. dollar is leading countries to sell their U.S. foreign reserves to help prop up their currencies, in turn buying currencies such as the Australian and Canadian dollars to help generate higher yields.

The above animated graphic from James Eagle shows the rapid ascent of the U.S. dollar over the last century, and its gradual decline in recent years.

Dollar Dominance: A Brief History

In 1944, the U.S. dollar became the world’s reserve currency under the Bretton Woods Agreement. Over the first half of the century, the U.S. ran budget surpluses while increasing trade and economic ties with war-torn countries, expanding its influence as the world’s store of value.

Later through the 1960s, the U.S. dollar share of global foreign reserves rapidly increased as political allies stockpiled the dollar.

By 2000, dollar dominance hit a peak of 71% of global reserves. With the creation of the European Union a year earlier, countries such as China began increasing the share of euros in reserves. Between 2000 and 2005, the share of the dollar in China’s foreign exchange reserves fell by an estimated 15 percentage points.

The dollar began a long rally after the global financial crisis, which drove central banks to cut their dollar reserves to help bolster their currencies.

Fast-forward to today, and dollar reserves have fallen roughly 13 percentage points from their historical peak.

The State of the World’s Reserve Currency

In 2022, 16% of Russia’s export transactions were in yuan, up from almost nothing before the war. Brazil and Argentina have also begun adopting the Chinese currency for trade or reserve purposes. Still, the U.S. dollar makes up 80% of Brazil’s reserves.

Yet while the U.S. dollar has decreased in share of foreign reserves, it still has an immense influence in the world economy.

The majority of trade is invoiced in the U.S. dollar globally, a trend that has stayed fairly consistent over many decades. Between 1999-2019, 74% of trade in Asia was invoiced in dollars and in the Americas, it made up 96% of all invoicing.

Furthermore, almost 90% of foreign exchange transactions involve the U.S. dollar thanks to its liquidity.

However, countries are increasingly finding alternative options than the dollar. Today, Western businesses have begun settling trade with China in renminbi. Looking further ahead, digital currencies could provide options that don’t include the U.S. dollar.

Even more so, if the U.S. share of global GDP continues to shrink, the shift to a multipolar system could progress over this century.
