The international financial system is an abstraction of reality. It evaluates the value of production and transaction and provides a framework for the flow of investment and financing. These are real and important things, but looking at the economy from a financial point of view captures only what has happened while lagging behind what is happening and what will happen.
The Mechanics of the Global Supply Chain
The concept of a supply chain is simple. All products begin with a primary element, from oil to manganese to corn. That element is refined so it can be sold to someone who will use it for purposes as diverse as cooking a meal or making a cellphone. Industrial production involves moving the primary element from its place of origin – like a mine or a farm – to locations where it is made into a specific product and moved to another factory or node, where it is further developed using components from other factories, then sent on to a string of other factories where it is further refined, until it can finally be sent to a consumer. The chain has multiple parts with branches and alternative movements that take a particular item to many points that produce seemingly unconnected things. A piece of cloth can become a shirt, or it might become a component of an electric drill, or perhaps used to wrap jewelry.
The global supply chain is, by its nature, enormously complex. It is also very difficult to create an abstract model of it because it is completely heterogeneous. Dissimilar things with utterly different histories are in constant motion. Whereas financial transfers are frequently abstract, without a physical dimension, the supply chain is inherently physical.
The immediate challenge to this model is the internet. But even that is a very physical thing. The cloud is a vast array of servers, located in a particular place, using physical entities that are manufactured and delivered to the site, and delivering its product through vast networks of physical fiber to other physical servers and then on to the user. The fastest way to take out the internet is not through cyberwar but with missiles targeting server farms. Transmission of any sort is a physical event. It can be interdicted.
The Supply Chain and the Trade War
Geopolitics is the study of the nation-state and its external and at times internal dynamics. It sees economics, politics and war as different dimensions of national behavior but still integrated into a single system. It uses geography to understand the constraints and imperatives in which the nation-state and its parts exist. Geopolitics looks at the military as a physical and therefore geographically constrained force. It sees the political system as shaped by geography as a nation comes to be in a certain time and place. And while its view of economics is aware of the abstract prism of finance, it is far more aware of the physical and geographical dimension of the economy – the supply chain.
The U.S.-China confrontation is expressed in the first interest as a financial relationship, generated by political forces. But it is intimately connected to China’s fear of a U.S. military blockade of the South China Sea and the United States’ fear of Chinese movement into the Western Pacific. China is afraid that its supply chains of both exports of finished products and imports of raw materials will be disrupted. The tariffs are a financial matter. The South China Sea is a military matter. Both become supply chain-focused economic matters.
