What Is a Dollar, Actually?

The Signal Report — Series I: The Foreign Country of Money — Entry 1

The dollar is the medium through which nearly every economic decision in your life is conducted — every paycheck, every purchase, every investment, every debt. It's the substrate of your financial existence. It's also, despite its omnipresence, one of the least-examined objects in ordinary economic life. The familiarity of the instrument has erased the strangeness of what the instrument actually is.

This entry takes the dollar as its first specimen. The questions it's meant to answer are basic ones, but the answers aren't. What, materially and institutionally, is the thing in your wallet? What does it promise, and what does it not promise? What sustains its value, if not the commodity that once stood behind it? And why does the structure of those answers matter for the analysis of everything the Signal Report will subsequently examine — markets, capital flows, valuations, political-economic outcomes — given that all of those phenomena are denominated in, and conducted through, the medium under examination here?

The dollar is a useful first specimen for a particular reason. The forces this publication will examine are forces that exceed the resolution of unaided perception. They're difficult to see. The dollar is the opposite case — a thing that's in front of nearly everyone, several times a day, and is nevertheless functionally invisible because its very ubiquity has rendered it transparent. If careful attention can't be brought to the most familiar instrument in economic life, the more demanding work that follows will have nowhere to begin.

Begin with what’s printed on it.
