This balkanization of the global economy is deeply stagflationary, and it is coinciding with demographic aging, not just in developed countries, but also in large emerging economies such as China. Because young people tend to produce and save, whereas older people spend down their savings, this trend also is stagflationary.

The same is true of today’s geopolitical turmoil. Russia’s war in Ukraine, and the West’s response to it, has disrupted the trade of energy, food, fertilizers, industrial metals, and other commodities. The Western decoupling from China is accelerating across all dimensions of trade (goods, services, capital, labor, technology, data, and information). Other strategic rivals to the West may soon add to the havoc. Iran crossing the nuclear-weapons threshold would likely provoke military strikes by Israel or even the United States, triggering a massive oil shock; and North Korea is still regularly rattling its nuclear saber.

Now that the US dollar has been fully weaponized for strategic and national-security purposes, its position as the main global reserve currency may begin to decline, and a weaker dollar would of course add to the inflationary pressures. A frictionless world trading system requires a frictionless financial system. But sweeping primary and secondary sanctions have thrown sand in this well-oiled machine, massively increasing the transaction costs of trade.
