Today at a Glance: China’s energy crisis is best understood through the simple, Econ 101 lens of supply and demand, with a particular focus on the coal market. Demand-side drivers primarily include a booming recovery from COVID-19 lows and a hotter-than-normal year that increased residential power usage. Supply-side drivers include coal shortages, import restrictions, utility price fixing, and CCP emissions targets. Net-net, we have demand up and supply down, leading to widespread shortages, rising costs, and a ripple effect that extends across the globe—the stage is set for what could be a long, cold winter. China’s Energy Crisis In last week’s newsletter piece—the aptly named Supply Chain Apocalypse —I made brief reference to China’s burgeoning energy crisis as a supply dislocation further compounding our global supply chain woes. In the days since that piece was released, China’s energy crisis went from under-the-radar to front page news—hitting “above the fold” in the Wall Street Journal, Reuters, and Bloomberg, among others, as experts bemoaned its potential to hammer our weakened supply chains and derail the global recovery. I’ve always been fascinated by energy—it is, quite literally, what makes our world work—so yet again, I found myself going down the rabbit hole, exploring the crisis in detail and attempting to distill its key drivers and potential effects. Here’s a simple breakdown of what I learned. Spoiler Alert: This may be China’s Energy Crisis , but in an interconnected global economy, nobody is insulated from this disruption. Background The growing Chinese energy crisis had (mostly) happened outside the spotlight of the mainstream media. To be sure, among real energy market observers, it had been a key topic for months, alongside European natural gas price spikes, carbon credit markets, and the normal course OPEC debates—but the narrative accelerated meaningfully on the back of other China woes ( Evergrande , supply chain disarray , etc.). China is most definitely feeling the pain, but we may be in the early innings (sorry, baseball analogies stick with you!), with the contagion likely poised to spread globally. The Impact What are the visible impacts of China's energy crisis? More than half of China's mainland provinces have been forced to limit electricity usage due to shortages. According to a recent Bloomberg article , the Chinese microblogging site Weibo is filled with stories of people sharing how their daily lives are being impacted by the crunch—no tap water, no cell service, no traffic lights, and even a shortage of candles. In the industrial sector, the largest industrial provinces are facing significant cuts just as they try to dig their way out of the backlog that has been created by COVID restrictions and supply chain kinks. Looking outside of China, we see widespread concerns among politicians and energy market experts over rising coal and natural gas prices (the latter of which deserves its own piece in the future). Policymakers are expressing real angst over the ability of their countries to adequately heat homes as winter months approach. The price chart of European natural gas tells a pretty scary story—much of Europe could be in for a long, cold winter. Suffice to say, the impact of the energy crisis is already quite bad—but it has the potential to get much, much worse. The Drivers of China’s Energy Crisis In attempting to understand the situation, it's important to understand that the economy is an interconnected web of activity. Nothing happens in a vacuum. This means that an energy crisis in China is not just about China—it has a complex set of causes and effects. In this situation, China's crisis is primarily related to coal. Why? Well, China is very reliant on coal—it has been the driving force of their economic growth. Here are two great visualizations of that reliance. While out of vogue due to its environmental impact, coal does remain a key source of electric power globally. The science is pretty simple (see the diagram below). Coal is burned, the heat released boils water, which produces steam, which drives a turbine, which produces electricity. To dissect the coal-driven crisis (and its ripple effects), we need a simple framework. Let's turn back to our Econ 101 classic: Supply & Demand. Note: In this framework, supply will refer to everything related to energy production, while demand will refer to everything related to energy consumption. Demand-Side Drivers First, demand. This is relatively straightforward: demand for coal (and the electricity it produces) is very high (and rising). The robust global recovery from COVID—and the resulting impact on goods manufactured in China—is one key driver of the demand surge. Domestic residential coal-powered electricity demand is also up, with a hot summer and lower than normal hydroelectric production. This latter point is worth noting, as it's a supply constraint in one area (hydroelectric) creating a demand surge in another (coal electricity). As the chart below shows, China has never before seen single year growth in thermal power demand of this magnitude. That creates significant strain on the system. Supply-Side Drivers Next, supply. This one is more complex, with several distinct—yet interconnected—dislocations. The main supply dislocations that I see here are: Coal Shortages Import Restrictions Utility Price Fixing CCP Emissions Targets (*impacts both supply and demand*) Let’s cover each one in a bit more detail: Coal Shortages Global coal supply has been seriously constrained due to a variety of factors. Coal mines globally have faced COVID-related shutdowns—with such closures hitting the news in the United States and Colombia , among others. In Colombia, energy giant Glencore walked away from its contra...
