PARIS: As the top global currency, the US dollar has enjoyed decades as the cash of choice for investors but it is now facing a growing challenge tothatstatus.

The greenback has been used for almost everything in terms of international trade and global finance, from ordering planes, buying oil, or issuing debt. But a number of developing economies, particularly China, have been leading a drive against overreliance on the US currency.

`In many developing coun-tries there is desire to be less dependent on the dollar, particularly on the trade side,` said Paola Subacchi, professor of International Economics at the Global Policy Institute at Queen Mary University of London.

On a visit to China in April, Brazilian President Luiz Inacio Lula da Silva asked why `all countries are forced to trade based on the dollar`, before signing an agreement with Beijing to provide commercial contracts denominated in yuan and reals. And Bangladesh announcedrecently it paid Russia for a nuclear power plant in Chinese yuan, as well as using its own currency for a delivery of liquefied natural gas from France`s TotalEnergies.

Sanctions The widely-used dollar gives the United States a big competitive advantage.

Emerging and developing countries are dependent on the movements of the US currency, which influences the price of their imports and their exports. US-set interestrates also influence the cost of dollar-denominated debt. But the dollar`s dominance has come under the spotlight since the war in Ukraine, which saw Washington and western countries impose sweeping sanctions on Moscow after it invaded Ukraine last year.

`The US uses its dollar hegemony to sanction Russia, said Larry Yang, chief economist at Shenzhen-based First Seafront Fund Management.

`Other countries feel concerned that they might be sanctioned by the US as well, andhence they have decided to opt for more currencies for payment and settlement,` he added.

`This change is good for the stability of international trade and it is definitely a long term trend.` China, the world`s second-largest economy and Washington`s great political rival, has been internationalising its currency for several years. But its currency is still largely restricted and regulated by the Chinese authorities.

Yang said the internationalisation of the Chinese yuan, also known as RMB, will meanmore countries choose the currency for international deals in the future.

`With China`s trade volume on a long term rapid ascending trajeetory ...

the level of RMB internationalisation will increase and there will be more trading partners opt for RMB payment and settlement,` he said.

Politics vs economics But others warn any significant move away from the dollar would require a number of key factors to be in place,including a transparent government framework, independent central bank, and investor security.

`Clearly, we`re entering a very delicate moment for the world economy, with lots of geopolitical tension and the world splitting into two large poles,` said Alessandra Ribeiro, an economist at the Tendencias Consultoria consultancy in Sao Paulo.

But she said proposals against the dollar are often `more political than economic`.-AFP
