Inflation is typically the symptom of an economy overheating. Workers can’t keep up with the demand for the vast array of things they make. Abundant dollars pursue scarce goods and services, forcing prices and wages up. The solution is simple enough: Central banks, such as the Federal Reserve, increase interest rates, applying brakes to the economy.
The Washington Post is either completely ignorant of economics, or they assumed that the phrase “expansion in the money supply” would mean nothing to their readers. I optimistically assume the former.
