China’s exports unexpectedly fell in August as shipments to the US slowed sharply, pointing to further weakness in the world’s second-largest economy and underlining a pressing need for more stimulus as the Sino-US trade war escalates.

Beijing is widely expected to announce more support measures in coming weeks to avert the risk of a sharper economic slowdown as the US ratchets up trade pressure, including the first cuts in some key lending rates in four years.

On Friday, the central bank cut banks’ reserve requirements for a seventh time since early 2018 to free up more funds for lending, days after a cabinet meeting signalled that more policy loosening may be imminent.

August exports fell 1 per cent from a year earlier, the biggest fall since June, when it fell 1.3 per cent, customs data showed on Sunday. Analysts had expected a 2.0 per cent rise in a Reuters poll after July’s 3.3 per cent gain.

That’s despite analyst expectations that a falling yuan would offset some cost pressure and looming tariffs may have prompted some Chinese exporters to bring forward or “front-load” US-bound shipments into August, a trend seen earlier in the trade dispute.

China let its currency slide past the key 7 per dollar level in August for the first time since the global financial crisis, and Washington labelled it a currency manipulator.

“Exports are still weak even in the face of substantial yuan currency depreciation, indicating that sluggish external demand is the most important factor affecting exports this year,” said Zhang Yi, economist at Zhong Hai Sheng Rong Capital Management.

Among its major trade partners, China’s August exports to the US fell 16 per cent year-on-year, slowing sharply from a decline of 6.5 per cent in July. Imports from America slumped 22.4 per cent.

Many analysts expect export growth to slow further in coming months, as evidenced by worsening export orders in both official and private factory surveys. More US tariff measures will take effect on October 1 and December 15.

“China-US trade friction has led to a sharp decline in China’s exports to the US,” said Steven Zhang, chief economist and head of research at Morgan Stanley Huaxin Securities.

Exports to Europe, South Korea, Australia, and Southeast Asia (Asean) also worsened on an annual basis, compared with July, while shipments to Japan and Taiwan posted slightly better growth than the previous month.

Sunday’s data showed China’s imports shrank for the fourth consecutive month since April. Imports dropped 5.6 per cent on-year in August, slightly less than an expected 6.0 per cent fall and unchanged from July’s 5.6 per cent decline.

Sluggish domestic demand was likely the main factor in the decline, along with softening global commodity prices.
