Answer:
$2 billion
Step-by-step explanation:
Let us recall the following statement from the question:
The purchase made by Fed = $200 million of U.S securities from the public
The requirement reserve is = 10%
Now,
let us recall the formula,
(1/r -1)
r = the reserve requirement of 10% or 0.1%
The initial money deposited is = $200 million
By applying the formula (1/r- 1)
The money generated from Fed is = $200 million * (1/0.1-1)
which is
$200 million * 9 = $1.8 billion
The money supply increase or growth = $200 million = 1.8 billion = 2 billion
The total impact on the money supply is $ 2 billion
