Not a main currency supply factor?

• A. Inflation
• B. Trade
• C. Gov Policy
• D. Speculation

Answer: (A)

Money supply is determined by the central bank’s actions and related government policy—things like policy interest rates, open market operations, and reserve requirements. These tools directly change how much currency is in circulation. Trade flows and speculative activity mainly influence the value of the currency in foreign exchange markets by affecting demand for it, not the total amount of money the central bank creates. Inflation, on the other hand, is a consequence of money and price dynamics: when the money supply grows faster than output, prices tend to rise. It doesn’t drive the creation of money itself, but responds to it and to other factors in the economy. So inflation isn’t a main currency supply factor.
