3. Give an example of a bank balance sheet with a leverage ratio of 10. If the value of the bank’s assets rises by 5 percent, what happens to the value of the owners’ equity in this bank? How large a decline in the value of bank assets would it take to reduce this bank’s capital to zero?
please refer from the textbook MACROECONOMICS by N Gregory Mankiw
Solution:
3.
The leverage ratio is ratio of book value of core capital to total assets,
where
core capital = book value of equity + qualifying cumulative perpetual preferred stock + minority interests
Assuming that bank has only equity with no preferred stock and minority interests, then leverage ration is given by:
for leverage to be 10, ratio between equity and total assets should be 2:1.
Bank Balance Sheet |
|
---|---|
Assets | Liabilities & Net Worth |
Reserves 20,000 | Deposits 70,000 |
Loans 50,000 | Debt 20,000 |
Securities 30,000 | Capital 10,000 |
In the above table,
Total Assets = 100,000.
Capital = 10,000
then
Leverage = 10.
If bank assets increase by 5%, to maintain constant leverage, owner's equity should increase in same proportion i.e. by 5%.
Bank Assets should decline by 10% (i.e 10,000) to reduce bank's capital to zero.
