Answer:
The correct answer is C. There was a significant increase in the monetary base during the recent financial crisis.
Step-by-step explanation:
The Central Bank determines the monetary base and from there, financial intermediaries generate bank money.
If we see the composition of the balance of a Central Bank, the monetary base is equivalent to total assets less non-monetary liabilities.
If the monetary base increases: money creation
If the assets of the Central Bank increase (increase in foreign exchange reserves, increase in credit to the banking system or the public sector) without increasing non-monetary liabilities, it will logically have to increase the monetary liability (creation of money).
If non-monetary liabilities decrease, without variation of the asset, you will necessarily have to increase the monetary liability.
