To avoid being financially strangled, China’s policymakers have accelerated the pace of diversifying its forex assets now dominated in the US dollar, while also empowering the home-grown Cross-Border Interbank Payment System and striving to boost the yuan’s use overseas.
However, China’s ambition to build the yuan into an international currency is curtailed by the fact that it is not as convertible as the US dollar or euro, and Chinese leadership also remains concerned about potential financial risk contagions.
Ju brought forward a concept of a progressive tax on cross-border capital flows to guard against external risks, after the country’s capital exodus from 2015-17 significantly slowed the pace of financial liberalisation.
“Such a policy design would be like installing a firewall and thus solving the dilemma of capital account liberalisation and yuan convertibility,” he said.
The professor did not speculate on possible rates or levy details for any such proposed tax arrangement.
Beijing has already imposed strict capital controls to counter portfolio investment outflows that surged last year amid China’s economic slowdown and zero-Covid policy, and more foreign direct investors are being courted to maintain the capital account balance.
The yuan’s overseas use has made strong inroads since Beijing started yuan-denominated trade settlements a decade ago. However, the yuan’s reach – accounting for just 2.19 per cent of global payments, 3.5 per cent of global forex transactions, 2.76 per cent of reserves held by central banks, and 12.28 per cent in the International Monetary Fund’s special drawing rights (SDR) currency basket – is still low compared with China’s roughly 18 per cent share of the global gross domestic product.
The Tsinghua professor said he believes that the US dollar is over-represented, relative to its economic strength, pointing to its 41.1 per cent proportion in global payments, 88 per cent of global forex transactions and 41.73 per cent of the SDR basket.
However, Ju pointed to one of the bright spots for China’s yuan – its burgeoning central bank digital currency known as the e-yuan. China has carried out research and pilot programmes for the last few years, and it is a world leader in the digital currency realm.
“If China can innovate the entire system through digital currency and establish a digital international currency system, it may have the opportunity” to strengthen the yuan’s overseas use, he said.
China’s central bank has already conducted e-yuan pilot schemes in more than 20 cities, involving nearly 5 million merchants and 100 billion yuan (US$14.5 billion) worth of transactions. However, no official timetable has been given for the digital yuan’s full roll-out.
The Chinese government also has not set any quantitative goals for the yuan’s overseas use. Instead, it said the work will be pushed forward “orderly”.
