China risks making “big mistakes” as it cracks down on large swathes of its economy from technology, to private tutoring and real estate, said a former chief economist of the International Monetary Fund.

“I worry a lot about China because to some extent they’re attacking the basis of their growth so far,” Raghuram Rajan told CNBC’s “Squawk Box Asia” on Friday.  

“At some point they have to abandon that method of growth and go to a new one. The question is: Are they trying to do it too quickly, and in the process, leaving less to support growth,” he said.

China has relied on cheap labor and cheap finance to grow its economy, said Rajan, who was IMF’s chief economist from 2003 to 2006. Moving away from that growth model creates “an enormous amount” of uncertainties, even though it’s necessary, he added.

So essentially you’re tackling a lot of things at the same time. When you do that, there’s a risk of big mistakes.

If property prices fall as a result of government measures, homeowners will feel poorer and local governments may lose revenue from lower land sales, he said, and pointed out that local governments are an important source of funding for local firms.

“So essentially, you’re tackling a lot of things at the same time. When you do that, there’s a risk of big mistakes,” said the professor.

Economic challenges facing China have led major banks to downgrade their 2021 growth forecasts for the world’s second-largest economy.

‘Higher for longer’ inflation

Rising inflation is one major challenge for the global economy, Rajan warned.

Inflationary pressures are looking to be less transitory than what central bankers had thought, said Rajan, who served as the governor of the Reserve Bank of India from September 2013 to September 2016.

Major central banks such as the Federal Reserve and the European Central Bank have suggested that spikes in inflation are temporary and would eventually subside.

But Rajan said there are signs that higher prices could last longer than expected.

Supply constraints — a source of accelerating inflation — have spread across sectors and countries, he explained. And rising energy prices have caused power constraints, which impose “yet more damage” on global supply chains that are already struggling with major bottlenecks, he added.

In the U.S., higher housing prices have caused rents to increase and would take time to translate into higher consumer prices, said the professor.

“So when you put all these together, it suggests that inflation would be higher for longer,” said Rajan.
