WHEN THE WORLD鈥橲 financial markets hit turbulence, could you really turn to China鈥檚 yuan as a store of value?

The idea of the yuan as a refuge has gained some traction in recent weeks as it capped its best quarter in 12 years relative to the dollar. That label would put it on par with currencies traditionally deemed as safe in a market downturn, like the Japanese yen or Swiss franc.

In addition to dollar weakness, the yuan is being underpinned by a wide interest-rate premium over the rest of the world, as well as signs that China鈥檚 economy is recovering from the shock of the pandemic. But unlike a haven, China鈥檚 tightly managed currency is gaining just as money flows into risk assets such as US stocks or high-yield credit. In other words, it is strengthening in a relatively benign market.

Buying the yuan as a shelter from market volatility isn鈥檛 new: in 2017, the Chinese currency proved to be a better bet than the yen when North Korea fired missiles into the Sea of Japan. But history also shows it鈥檚 a risky strategy 鈥 when the yuan showed haven-like resilience in early 2018, it slumped to a decade low that year after the Trump administration slapped its first tariffs on Chinese goods.

Considering the policy risk in China and its capital controls, viewing the yuan as a haven will be inappropriate, according to George Magnus, research associate at Oxford University鈥檚 China Centre.

鈥淭he yuan can be considered a 鈥榞ood trade,鈥 which is a cyclical phenomenon and has nothing to do with haven status 鈥 the conditions for that are largely unfulfilled,鈥 said Mr. Magnus. 鈥淚t is not and cannot be, as things stand, a viable alternative to the dollar or the euro, which have economic and institutional properties to which Xi鈥檚 China鈥檚 yuan cannot aspire.鈥

Yuan鈥檚 rally this year stokes discussion on whether it鈥檚 a haven currency

The central bank maintains a tight grip on its currency, and can often dictate its direction with the fixing which restricts movement by 2% on either side. The People鈥檚 Bank of China (PBoC) has recently allowed gains in the yuan, on Friday setting its daily reference rate at a stronger-than-expected level.

But on Saturday, the PBoC made betting against the yuan cheaper, a sign that it may be growing uncomfortable with the currency鈥檚 rapid appreciation. It reduced the cost of trading some foreign-exchange forwards, or derivatives often used to speculate against currencies, to zero from 20%.

A haven yuan would require China to have a more liquid financial market and open capital account, according to Eswar Prasad, a senior fellow at Brookings Institution. China would also need to show some of the key elements of an institutional framework, such as an independent central bank and a political system that鈥檚 typically associated with a democratic government, said Prasad, who once led the International Monetary Fund鈥檚 China team.

The Communist Party also controls the amount of money flowing out of the country, with citizens permitted $50,000 worth of foreign exchange purchases per year.

The yuan jumped about 4% in the three months through September, the largest quarterly gain since early 2008 and beating the Swiss franc and Japanese yen. The yuan is also particularly stable, with expected swings the lowest among 30 major exchange rates apart from the pegged Hong Kong dollar.

Haven or not, the yuan will likely stay strong given the attractive yield of China鈥檚 10-year government bonds, which is at the highest since December. FTSE Russell, Bloomberg Barclays and JPMorgan Chase & Co. now include onshore bonds in their indexes, a move that will help attract steady capital inflows in the coming years. Bloomberg LP owns Bloomberg Barclays and Bloomberg News.

鈥淚nvesting in China is likely to remain a good bet as the economy strengthens, and with it the renminbi鈥檚 value,鈥 said Prasad, using the yuan鈥檚 official name. 鈥淏ut that does not mean the currency has become a safe haven. It is unlikely that the renminbi will be seen as a true safe-haven currency in the absence of more far-reaching institutional reforms, which appear unlikely.鈥 鈥 Bloomberg
