> Inflation is an increase in the money supply which also happens to increases prices.
This is not a definition I have seen used by academic or working economists. If the purchasing power of $1 decreases, we can say there has been inflation. Even if the money supply is constant, if shirts used to cost $10 but now cost they cost $100 due to increased demand, a supply shock, a union strike, a tax, or a speculative shirt buying bubble, it would be considered inflation in all of those cases, regardless of the cause.
It sounds like you mean monetary inflation, but the fed’s mandate is not to control monetary inflation (which would be a lot simpler) but to ensure stable prices. The mandate has no exception for non-monetary causes of price instability.
Of course measuring how much a dollar can purchases is an enormously complex and subtle task that can be approached in many different ways. But the whole argument for tariffs is that foreign producers of goods are selling them so cheaply that American producers cannot compete. So if we increase the price of those foreign goods by adding a tax on it and shift some good consumption to more expensive American producers, that’s obviously going to reduce what a dollar can purchase.
