Autarkic

Definition: a policy of establishing a self-sufficient and independent national economy

Why I Looked It Up

A book on the oil industry said this about an economic recession.

Only the Soviet Union, with its autarkic planned economy, was unaffected.

Postscript

I found this definition in a discussion of fascism:

Autarky: fascist countries reject both economic socialism and the free market of capitalism and prefer to be completely self-sufficient without relying on other nations.

I found this quote in a book about financial networks:

Mid-century dreams of autarky yielded to a glad, confident era where comparative advantage could once again be exploited.
