Exploring the data sources listed above, try to understand the banking sector in your country/region through—depending on data availability—the following indicators:

(a) Size: total bank assets relative to GDP. How is the size of the banking sector evolving over time?

(b) Types of banks: 

i. How many types of banks are defined by law? How many banks are there in each category? What is the share of each category in total bank assets? 

ii. How many foreign-owned banks are there? What is the share of foreign banks in total bank assets? Among them, how many are foreign subsidiaries and how many are foreign branches?

(c) How important is bank funding, versus market funding?

Would you categorize the economy as “market-oriented” or “bank-oriented”?

(d) Bank performance: 

i. How is banks’ average return on assets (ROA) evolving over time? How about banks’ average return on equity (ROE)? 

ii. How is banks’ average net interest margin (NIM) evolving over time? 

iii. Do banks rely more on interest income or non-interest income? How is the dependence evolving over time?

(e) What is the share of retail deposits in banks’ total liabilities?
What is the share of wholesale funding?

(f) Were there any banking crises, or influential episodes of failed banks in history? What were the causes and major consequences?
