Market gloom over the health of the Chinese economy has flipped to optimism that government stimulus has taken it past its soft patch. But Tuesday’s disappointing manufacturing surveys show that investors should be wary of getting too carried away by this year’s bumper market rally. Beijing responded to gross domestic product growth of 6.6 percent last year – stellar by developed market standards, but China’s slowest in three decades – with a mix of fiscal and monetary stimulus, including tax cuts and a reduction in the share of deposits that banks must hold in reserve.  That response had appeared to be working, by some measures at least. Big increases in the likes of cement production, new energy vehicles and steel drove slightly higher than expected GDP growth in the first quarter, figures showed in mid-April.

But the downbeat numbers from the two more recent Chinese manufacturing surveys – one official and one from the private sector – have injected some healthy skepticism into a market consensus emerging around Beijing’s ability to support its economy. That should act as a check on China ‘s rampant stock market. After falling by a quarter in 2018, the  300 benchmarks has rocketed 30 percent this year, helping hedge fund managers such as Paul Tudor Jones who bet on a recovery. The more gloomy manufacturing data should also make investors think twice about bets that stimulus will be a big positive for economies dependent on China.

Silvia Dall’Angelo, a senior economist at Hermes Investment Management, has penciled in GDP growth of 6 percent to 6.5 percent for China this year but warns that “the [stimulus] measures are way more targeted and way more limited” than previous rounds. “The external spillover will be less,” she said. For similar reasons, Ms. Dall’Angelo is negative on the Australian dollar, which is down sharply over the past year. In Germany, “the green shoot of Chinese data has not been expressed yet into Germany’s manufacturing data”, according to Citigroup.
