- Banks provide a safe place for individuals and businesses to park their money.

- Credit control:

- This is more commonly a function of central banks, not commercial banks.

- Central banks influence the credit policies of commercial banks.

- Loaning to other banks:

- This is not a primary function of commercial banks.

- Interbank lending occurs but is not a main focus.

- All the above:
