Start at Equilibrium

The market for dollars begins in equilibrium where the demand for dollars (D$) equals the supply of dollars (S$). The vertical axis measures foreign currency per dollar.

Higher US Inflation: The Dollar Depreciates, step by step

  1. 1

    Start at Equilibrium

    The market for dollars begins in equilibrium where the demand for dollars (D$) equals the supply of dollars (S$). The vertical axis measures foreign currency per dollar.

  2. 2

    US Inflation Rises, Supply Shifts Right

    US inflation rises, so American-made goods become relatively more expensive than foreign goods. Americans buy more imports, and to pay for them they must supply more dollars to the foreign exchange market, so the supply of dollars shifts right.

  3. 3

    The Dollar Depreciates

    At the new equilibrium the exchange rate is lower, so each dollar buys less foreign currency and the dollar has depreciated. The equilibrium quantity of dollars traded rises as the larger supply is absorbed by the market.

Where it ends up

The dollar depreciates while the equilibrium quantity of dollars traded rises, as Americans supply more dollars to buy relatively cheaper foreign goods.

Now draw it yourself
