No, that is expansion of the monetary base. Inflation is an increase in price levels. If a country’s money supply contracts while prices rise that’s inflation.

The problem with the metallic definition is a country that loses half its territory and most of its reserves after losing a 19th-century war, thereby setting off double-digit price increases across its economy, doesn’t “inflate” from a monetary base perspective. Once we understood these concepts were separate, we segregated the terms. Insisting inflation refers exclusively to monetary-base expansion is phlogiston-theory stuff.
