Open Banking: everything you need to know about this advantageous banking system

1. What is open banking?

Open banking is a financial services concept that allows customers to share their financial data with third-party providers, such as fintech companies and other financial institutions, through the use ofAPIs. This gives customers more control over their financial data and allows them to access a wider range of financial services, such as budgeting tools, investment platforms and other financial management tools.

The concept ofopen banking was first introduced in the UK in 2016, through the introduction of the Payment Services Directive(PSD2). This directive requires banks to provide third-party providers with access to customer financial data, with the consent of the customer. This has led to the widespread development of fintechs, offering a wide range of financial services to customers, using their bank account data.

The benefits ofopen banking are numerous. Customers have more control over their financial data and can access a wider range of financial services. For fintech companies, they have access to a large amount of customer financial data, which they can use to develop new products and services. For banks, this means they can partner with fintech companies to offer new services to customers, and also that they can use customer financial data to offer more targeted products and services.

Despite the many benefits, there are also some concerns associated with open banking. One is that customers may not fully understand the implications of sharing their financial data with third-party providers. Another concern is the security risks associated with sharing financial data through APIs.

To address these concerns, a number of regulatory measures have been taken. For example, PSD2 requires banks to implement strong customerauthentication measures to ensure that only authorized parties can access customer financial data. In addition, there are a number of security standards that third-party providers must adhere to, such as the Open Banking Security Profile.

Open Banking is a financial services concept that has the potential to revolutionize the way we manage our money. By giving customers greater control over their financial data and access to a wider range of financial services, it creates a more competitive and innovative financial services marketplace.

2. How does the open banking system work?

Open Banking allows customers to share their financial data with third-party providers through the use ofAPIs (application programming interfaces).

This gives clients greater control over their financial data and access to a wider range of financial services, such as budgeting tools, investment platforms and other financial management tools.

Theopen banking process typically begins when a customer gives permission for a third-party provider to access their financial data. This is done through a secure online portal, where the customer can see what data is being shared and with whom.

Once the customer agrees, the third-party provider can access the customer's financial data through the bank'sAPI . This allows the third-party provider to access information such as transaction history, account balances and other financial data.

The third-party provider can then use this data to develop new products and services for the customer. For example, a budgeting application may use transaction history to create a budget for the customer, or an investment platform may use account balances to recommend investment opportunities.

Data is shared in real time and the customer will always have the option to revoke access to their data.
