China's Q1 economic rebound faces rough seas as Iran war jolts global outlook

Highlights

• China's Q1 GDP growth picks up to 5.0% from Q4's 4.5%
• Retail sales growth and industrial output cool in March
• Iran war raises growth risks, set to test policymaking
• More fiscal stimulus expected if exports falter

China's economy picked up speed early in 2026, riding an export surge before the Iran war sent energy costs soaring and put global demand - vital to Beijing's growth ambitions - at risk.

The 5.0% year-on-year pace in the first quarter sits at the top of China's full-year target range of 4.5%-5.0%, highlighting a resilience that sets it apart from much of Asia, helped by ample strategic oil reserves and a diversified energy mix.

Yet the Middle East conflict lays bare a core vulnerability: an export-led growth model that delivers annual trade surpluses the size of the Dutch economy depends on open sea lanes - for China and for the customers it sells to.

And as the world's biggest energy importer and manufacturing powerhouse, soaring oil prices threaten to drive up production costs and squeeze already thin margins at factories that employ hundreds of millions of people. The longer the conflict drags on, the higher the risks, and the pressure is already mounting.

Peng Xin, general manager of Guangdong Rongsu New Materials, which buys petrochemical feedstock from refineries and turns it into plastic pellets for injection-moulding factories, says prices for two types of nylon spiked roughly 40%-60%.

Peng is passing the increases on, while some of his customers rush to place orders and stockpile before costs climb further.

"The current coping method is to negotiate the price for every single order. If you accept my price, we cooperate. Otherwise, there's nothing we can do," he said.

"The entire industry chain is under pressure."

Imbalances expose China to global demand risks

The first-quarter GDP growth beat forecasts of 4.8% and October-December's three-year low of 4.5%, which a statistics bureau official described as a "rare and commendable" achievement, while warning of a "complex and volatile" external environment.

But the trade data for March earlier this week pointed to strains. Exports grew just 2.5% last month, slowing sharply from 21.8% in January–February.

And while factory-gate prices rose out of deflation in March for the first time in more than three years, analysts warn "bad inflation" driven by input costs could be even worse for growth.

"The solid start to the year on the back of strong export performance suggests the direct impact of the Middle East conflict remains contained for now," said Junyu Tan, North Asia economist at Coface.

"But the outlook is not all rosy despite China's relative resilience," Tan added. "The export engine could still be constrained by weaker global demand if the conflict persists."

And the economy remains imbalanced, with consumers unlikely to pick up the slack if exports falter.

Retail sales, a gauge of consumption, grew 1.7% last month, down from 2.8% in January-February, and - as has been the norm in recent years - underperformed industrial output, which rose 5.7% in March versus 6.3% in the first two months.

Lending data earlier this week also showed sluggish credit demand from households and businesses.

Breaking China's protracted property slump will be critical to reviving consumption, but fresh data showing new home prices still falling suggest further pain for the country's embattled developers.

"On one hand you see resilience - the Iran war's impact on China is very limited. On the other hand you see imbalance - a strong export sector versus modest domestic demand," said Tianchen Xu, senior economist at the Economist Intelligence Unit.

Beijing to ramp up stimulus if exports slow

Analysts do not expect the central bank to ease policy significantly, but say Beijing could deploy more fiscal firepower if the target comes under threat, adding to a debt burden more than three times the size of the economy.

Fiscal expenditure rose 3.6% in January–February, picking up from a 1% increase in 2025.

"The net exports' contribution to Chinese growth could turn negative in the second quarter," said Dan Wang, China director at Eurasia Group.

"If that happens, then the domestic infrastructure spending and fiscal spending will step up in order to bridge the gap."

There is one silver lining for China, however. Cut off from the West after invading Ukraine, Russia now supplies it with discounted oil and gas. Heavy use of coal, rapid expansion of renewables and a growing electric vehicle fleet further shield China from energy shocks.

As the Iran crisis jolts markets, Chinese manufacturers may emerge in better shape than rivals in Europe and elsewhere, where production costs rise even faster.

"In a cost-push inflation cycle, firms normally cannot fully pass on the cost increase to consumers, and this will hit their profit margin," said EIU's Xu.

"That said, Chinese manufacturers still enjoy lower production costs relative to peers in other countries. That will help to preserve, if not increase, their global market share."
