The Chinese yuan’s best quarter in 12 years is drawing renewed international attention to the currency.

The onshore renminbi gained 3.8% in the three-month period ending Sept. 30, the most since early 2008, while its offshore counterpart advanced more than 4%. That’s more than Group-of-10 currencies including traditional havens like the Swiss franc and Japanese yen.

China’s success in fighting the coronavirus and its economic fallout has attracted both praise and investment, and prompted some speculation that the yuan could eventually become a new sanctuary for the risk-averse. Of course, the nation still tightly controls its exchange rate versus a basket of currencies, and determines how much money is able to cross its borders -- taboo for many international asset managers -- but those measures have also stabilized the currency even as price swings pick up elsewhere.

The offshore yuan has been “less volatile throughout this time period and the liquidity in the currency remains quite good relative to many currencies,” Brad Bechtel, global head of foreign exchange at Jefferies, said in a Bloomberg TOPLive blog on Wednesday. “China has done a lot of work on improving their capital markets and access to those markets and that is likely to continue which will improve liquidity and attract capital flows.”

Investors sent the offshore yuan to its highest since May 2019 on Wednesday, with the currency rallying as much as 0.8%, the most in almost three months. Overseas holdings of Chinese sovereign debt have meanwhile risen 22% this year through August.

China is set to be the only major economy to grow this year after the Covid-19 outbreak battered the world’s productivity. Economists surveyed by Bloomberg expect the nation’s GDP to rise 2.1% compared to a 4.4% estimated drop in the U.S., where disagreement around further stimulus, fears of a virus resurgence and election risk are damping expectations.

The yuan now often trades as much per day as the franc or sterling, Bechtel said. Trading in the currency grew 41% between 2016 and 2019, with a snapshot of turnover taken by the Bank for International Settlements in April last year showing an average $285 billion-a-day changed hands, just behind volumes in the Swiss currency.

It’s having a greater impact on the rest of the foreign-exchange market as a result, with correlation between the offshore yuan and currencies including the pound and Australian dollar strengthening since the start of the pandemic, according to HSBC Holdings Plc.

But despite the yuan’s growing influence, barriers remain to its wider use. While global reserves in the Chinese currency have grown to 2.1%, up from 1.4% two years ago, the dollar remains dominant; more than 60% of holdings are still denominated in the U.S. currency, according to data from the International Monetary Fund.

The yuan also carries more risks than its G-10 counterparts. Not only does China’s managed exchange rate make for policy surprises, such as 2015’s devaluation, investors must also stay savvy to global trade tensions.

“Recent Chinese output data has been reassuring, but this can be linked with state support and pent-up demand from abroad,” says Jane Foley, head of foreign-exchange strategy at Rabobank. “Looking ahead, U.S.-China tensions and trends toward on-shoring makes us very cautious.”
