"This description of the relationship between monetary policy and money differs from the description in many introductory textbooks, where central banks determine the quantity of broad money via a ‘money multiplier’ by actively varying the quantity of reserves.(3) In that view, central banks implement monetary policy by choosing the quantity of reserves. And, because there is assumed to be a stable ratio of broad money to base money, these reserves are then ‘multiplied up’ to a much greater change in bank deposits as banks increase lending and deposits. Neither step in that story represents an accurate description of the relationship between money and monetary policy in the modern economy. Central banks do not typically choose a quantity of reserves to bring about the desired short-term interest rate.(4) Rather, they focus on prices — setting interest rates.(5)"
Does that mean the whole "Fractional Reserve Banking" explanation is not how it works?
