What would happen if banking didn’t exist?

In case banking did not exist:

The housing industry would take a major hit. People would have to save their money at home.

Paying bills would be very difficult, as you would have to take cash to the bill owner.

Paychecks would not exist and instead you would be paid in cash.

Loans could not be granted.

Banking system refers to a network of commercial, savings, and specialized banks that provide financial services.

Before banking existed, no one was able to get loans or safely store their money. They used to store all of their money in small clinch bags. Hope my answer was useful, and don't forget to make this answer the best answer!
