China singling out Australian coal is a sign of their influence on global energy markets
Energy markets are a hot topic now with gas prices going vertical in Europe and coal prices breaking all-time highs. There have been numerous hypotheses lodged online blaming some very plausible causes including reduced gas storage and nuclear and some where the causal link appears to be missing, like renewables. Renewables are variable, but without them Europe would undoubtedly need more gas and be in more strife.
Over the last year I’ve been working on a project with Australian National University on China’s coal markets and logistics and how domestic drivers lead to massive changes in imports. This focus has perhaps given me a different lens to look through recent energy market developments.
China’s energy markets and global markets, especially for LNG and pipeline gas, have become increasingly integrated over the last five years.
For gas producers this has been a boon – a major new customer with strong growth while European demand has broadly been declining to flat over the period. It also means that what happens in China’s domestic energy markets does not often stay in China’s energy markets but is propagated throughout the world. When China has shortages or surpluses of gas, coal or electricity they spread rapidly across the world as China is a major and volatile importer of these commodities.
By mid to late 2020, coal was looking to be in serious trouble. Chinese inventories were high and shipping data showed that much of the supply of coal to southern China was now coming from Northern China ports leaving little room for thermal coal imports and not just from Australia which was singled out for special treatment. Then something strange happened.
From early 2021 China started to draw its coal inventories down hard and deliveries from northern ports to southern ports started to drop. This might not be a big deal, but China’s power demand was flying at the time with electricity consumption up ~14% year-over-year in April-June and steel output up 21%. Coal stocks started to decline rapidly.
So demand was very strong but supply fell behind sharply both for domestic production and imports. China’s coal production is heavily concentrated in a few provinces.
Over this period Inner Mongolia and Shaanxi output was poor – especially in the context of surging electricity consumption driven by industrial output of metals.
Imports were also weak from two major suppliers: Australia for political reasons and Mongolia ostensibly for Covid reasons.
There is however another possible reason. During this period there was something of an anticorruption crackdown in Inner Mongolia which borders Mongolia.
Around March, Xi Jinping was making explicit reference to anticorruption measures around the coal sector in Inner Mongolia. The collapse in imports and production over this period likely led to a shortage of approximately 30MT attributable to lost production and another 12MT from Mongolian imports. If you look at global seaborne coal imports, that is about two months of global imports, including China.
In gas equivalent terms, we know China takes about 330kg of coal per MWh of power, and a combined cycle gas turbine uses around 7GJ of gas per MWh. All in you are looking at bump in LNG demand to fill this hole equal to 5% of *annual* gas demand in Europe per IEA data.
What can or should we take away from this?
- Firstly that global energy markets are tightly coupled now via fossil fuels. Expansions in LNG infrastructure and pipelines mean that regional prices should in general be more tightly correlated.
- European gas demand is falling but varies with renewable generation and weather. More storage of gas but also pumped hydro and nuclear will be required.
- China is so big that seemingly obscure provincial corruption crackdowns in key areas can roil energy markets.
- China does not seem to be stepping back from mass campaigns and the like any time soon.
- The cost of fossil fuels is not just emissions but also in exposure to this volatility – if the energy transition seems expensive, remember that heating your home this winter in Northern Europe means you are paying a premium for China’s institutional and political volatility.
With China’s inventories low and winter heating and power demand starting to rise soon China can be expected to increase imports – although this will likely last only until China can supply its own needs again.
