The world is evolving digitally, and industries are competing to provide digital experiences faster. In return, consumer behavior is also evolving accordingly. With personalization and multiple online payment options, the way transactions take place has completely evolved. However, this leads to a big problem of how banks will safely share the necessary financial data of customers with third-party vendors. 

A slight vulnerability in the system can expose consumer data to fraudsters and bots built with malicious intent. To help resolve this problem, the methodology of open banking came into existence. It enables safe and secure data sharing between vendors and financial institutions with the help of application programming interfaces (API). There are several fintech companies and payment processors that use this approach to offer their financial services and ensure safe banking for all users. 

In this article, we’re going to discuss in more depth about what is open banking, how does it work, and what its various benefits are.

What is Open Banking in Layman Language?

When you make payment on some eCommerce websites, need a financial software to analyze your portfolio, or are simply filling tax returns and need to link your bank account with a government website or third-party accountant, chances are that the vendor first needs to communicate with your bank.

This communication does not happen directly, which would be extremely difficult, time consuming, or even unsafe because of a non-standardized approach. Instead, vendors use an application programming interface. This approach to sharing essential customer data and financial information is called open banking.

You may think of this as a digital doorway that banks use to talk to third-party apps. From traditional banks to modern private banks, nearly all of them rely on open banking to ensure safe and sound financial operations. 

How Open Banking Works in Practical Sense?

Banks often store sensitive customer data, such as account numbers, transaction details, account balance, identity proofs, and transaction data in their own private systems. These systems are designed for advanced data protection, are compliant with consumer data rights, and have next-gen fraud prevention measures in place. 

When an external vendor asks for some information, open banking standards apply. These mandate data formats and communication protocols, which can be followed with the help of APIs. This way, open banking enables interoperable financial services and secure exchange of information between banks and authorized third-party providers. 

Usually, the following types of APIs calls happen to ensure data privacy:

  • Data APIs: These only provide read-only access to third-party vendors. They can only view information for which you provide an explicit consent. 
  • Transaction APIs: These are often called by payment initiation services and can lead to an authorized fund transfer. 
  • Product APIs: Instead of sharing customer data, these APIs are called by third-party financial websites to review and list a bank’s financial products, rates, and terms, on their website.

Is Open Banking Safe?

When thinking about what is open banking, you must be thinking if it is safe. Exploring financial ecosystem through open banking is generally considered safe because of the following reasons:

  • Open banking works on a consent-first model. Meaning, banks can only share financial information when customers provide an explicit consent. This consent can also be limited to certain data only.
  • Even with the use of standardized and authorized APIs, data encryption technologies are always in place to encrypt sensitive information. The shared data is only decrypted when it reaches the authorized third-party provider. 
  • Along with banks and APIs, even the providers using open banking must meet all regulatory compliance. Vendors that do not comply with or follow data protection measures cannot use open banking. There are several organizations in the world, like Competition and Markets Authority (CMA) and Consumer Financial Protection Bureaus (CFPB) who timely update regulations for these vendors.
  • In the end, consumers retain complete control and transparency over the process. They can review their data was shared with which lender and can revoke access and permission any time from the API.

Note: Not all types of security risks can be resolved through the aforementioned measures in open banking. Certain risks vary depending on complexity or how your bank system works to proactively prevent and resolve them.

Common Uses of Open Banking

Here are some examples of how open banking is used in real-life scenarios:

  • For purchasing products and services through eCommerce platforms and OTT apps. These apps often allow customers to make direct transfers from their banks without including debit cards or credit cards.
  • For viewing your financial information like account balance, spending patterns, and more through third-party apps.
  • For aggregating account details in one place. Meaning, instead of opening multiple bank apps to review details, open banking can be used to view details from all banks in a single app.
  • For receiving financial advice related to investment and stocks from third-party apps.
  • To use specialized financial technologies like accounting software, budgeting software, and more.
  • To enable recurring payments for software subscriptions, recurring orders, and more.
  • Also used by banks and government regulatory bodies for inspecting compliance and identifying vulnerabilities in the open banking process. 
  • Credit institutions review your financial statements, spending patterns, and deduct payments for loan repayments.
  • Small businesses to set up billing and invoicing on your bank.
  • Sometimes, even banks use open banking to review your statements, financial products usage, and recommend personalized loan offers and financial products.
