Money Multiplier
Model

The money multiplier model traces how the banking system expands the monetary base into a larger money supply. The multiplier m = (1 + cr)/(cr + rr) depends on the currency-deposit ratio and the reserve-deposit ratio, so M = m * MB.

Compare

Side-by-side scenario comparison. Static equilibrium — point equilibria only.
