In case you’ve missed it there’s been a boom in cement demand in China during the current quarter. Henan province saw a run on cement prices in November 2019 that the local press described as ‘crazy.’ Some companies were issuing price adjustments twice a day, according to the China Cement Association. The article on the CCA’s website also includes a video showing dozens of cement trucks queuing at a mill with the caption ‘all the plants are like this, don’t ask the price any more.’
The CCA’s blamed the situation in Henan on pollution controls on production and a rebound in cement demand. Weather-based pollution controls enacted in late October 2019 shut-down or limited production at 66 of the province’s 72 clinker production lines. Builders were then forced to source cement from neighbouring Shanxi, Hebei and Shaanxi provinces. At the same time demand for cement from real estate and infrastructure sectors picked up in the fourth quarter of 2019. Following advice from the local cement manufacturers’ association, the provincial government relaxed the rules on peak shifting that normally run from November to February in a bid to control the situation. Cement prices in Henan hit a high in mid-to-late November 2019 and have since subsided somewhat.
Nationally, Chinese cement prices hit a high in late November 2019 beating the highest level in 2018 and also setting the highest price since 2011. The key regions driving the increase have been in central and south China, including Guangxi, Guangdong and Henan. One more thing to note here is that peak shifting or seasonal shutdown of production capacity has different dates in different provinces. So, potentially, the situation could repeat itself if unexpected demand continues and provincial governments fail to monitor the situation.
Recently a couple of economic indicators in China have suggested a recovery in infrastructure spending in recent months, supporting increased cement demand. Data from Wind quoted by the Financial Times newspaper suggests that the cement price rose by 15% since September 2019 in large cities. Reinforced steel (rebar) and aggregates prices have increased similarly. At the same time the South China Post newspaper has reported a growth in the Purchasing Managers’ Index (PMI), an indicator of manufacturing activity that could also point to renewed infrastructure spending. Central government is also reported to be taking measures to support provincial infrastructure development.
If true then this may be creating some pretty direct lessons in economic interventionism. The Chinese government appears to be stimulating demand for cement via infrastructure growth while restricting production at the same time. Cement prices have reacted in a ‘crazy’ fashion. The real tension here is between two conflicting desires: protecting the economy and protecting the environment. The state planners may be grappling with this one for a while.
