China's August retail sales miss forecast while investment slump deepens, piling pressure on Beijing

China's investment slump deepened and retail sales growth slowed further in August while industrial output topped estimates with authorities warning of acute supply-demand imbalance at home.

Retail sales grew 0.4% in August from a year earlier, data from National Bureau of Statistics showed on Tuesday, slowing from 0.6% in the prior month and missing economists' forecast for a 0.8% growth in a Reuters poll.

Industrial output expanded 5.2% last month, accelerating from 4.5% growth in July and outperforming economists expectations for a 4.8% rise.

For the first eight months of the year, urban fixed-asset investment, which covers property and infrastructure investment, shrank 7.2% from a year earlier, steepening from 6.7% decline in the January-to-July period, matching analysts' expectations.

The urban survey-based unemployment rate in August ticked up to 5.3% from 5.2% in July.

"We should be aware that the adverse impact of (the) external environment has intensified," the statistics bureau said in an English-language release. It noted "acute" imbalance domestically between "strong supply and weak demand," adding that some businesses still faced operational difficulties.

In the statement, the NBS called for stepping up macro-policy adjustments and boosting domestic demand, while advancing industrial upgrades for "innovation-led" development.

Growth in the world's second-largest economy slowed to 4.3% in the second quarter, the weakest pace in more than three years, veering further from Beijing's annual target of 4.5% to 5%. Policymakers have so far resisted more aggressive stimulus, relying instead on incremental measures to shore up growth.

Export resilience has powered the economy, as a global investment boom in artificial intelligence lifts demand for Chinese semiconductors and tech hardware. The country's massive oil stockpiles have also offered a further buffer against surging energy prices, allowing the world's biggest crude importer to scale back imports.

China's official manufacturing purchasing managers' index showed new orders and output both returned to expansion in August after contracting in July.

Efforts to fire up appetite for new debt have, however, fallen short. China's credit expansion in August missed forecasts by a wide margin, with government bond financing unable to offset sluggish corporate and household demand.

New bank loans expanded by just 60 billion yuan ($8.95 billion), versus a roughly 400 billion yuan forecast and down from 590 billion yuan a year earlier, while outstanding loan growth slowed to a record-low 4.9%.

A team of economists led by Raymond Yeung, China economist at ANZ Research, said in a note earlier this month that "September could represent an important policy window to revive business confidence ahead of October's Golden Week holidays." More fiscal support is needed, but a policy rate cut remains unlikely, they added.
