Alternative currencies are too unstable for the dollar to lose dominance

Some governments such as that of China might try to offer alternatives to the US dollar, but they are unlikely to succeed.

Government-to-government transactions, for example for crude oil between China and Saudtti Arabia, could be denominated in yuan. But then the Saudi government would have to find something to do with the Chinese currency it receives. Some could be used to pay for imports from China, but  a lot less from China (about US$30 billion) than it exports (about US$49 billion) to the country.

The US$600 billion  (PIF), Saudi Arabia’s sovereign wealth fund, could of course use the yuan to invest in China. But this is difficult on a large scale because Chinese currency remains only partially “convertible”. This means that the Chinese authorities still control many transactions in and out of China, so that the PIF might not be able to use its yuan funds as and when it needs them. Even without convertibility restrictions, few private investors, and even fewer western investment funds, would be keen to put a lot of money into China if they are at the mercy of the Communist party.

China is of course the country with the strongest political motives to challenge the hegemony of the US dollar. A natural first step would be for China to diversify its foreign exchange reserves away from the US by investing in other countries. But this is easier said than done.

There are few opportunities to invest hundreds or thousands of billions of dollars outside of the US.  show that the euro area bond market – a place for investors to finance loans to Euro area companies and governments – is worth less than one third of that of the US.

Also, in any big crisis, other major OECD economies like Europe and Japan are more likely to side with the US than China – making such a decision is even easier when they are using US dollars for trade. It was said that states  refused to condemn Russia’s invasion of Ukraine, but this half does not account for a large share of global financial markets.

Similarly, it shouldn’t come as a surprise that democracies dominate the world financially. Companies and financial markets require trust and a well-established rule of law. Non-democratic regimes have no basis for establishing the rule of law and every investor is ultimately subject to the whims of the ruler.

When it comes to global trade, currency use is underpinned by a self-reinforcing network of transactions. Because of this, and the size of the US financial market, the dollar’s dominant position remains something for the US to lose rather for others to gain.
