Introduction to Open Banking Concepts
Open banking refers to securely sharing bank customer financial data with authorized third party apps and services via APIs (application programming interfaces)
This represents a fundamental shift compared to closed legacy banking models where…
- Banks entirely controlled silos of customer data
- Customers lacked easy ability to analyze finances across institutions or access innovative third-party offerings
With open banking:
- Banks provide granular access to customer data via standardized APIs
- Customers retain ownership and authorize secure sharing with trusted recipients
- Recipients can develop customized services catering to diverse financial needs leveraging shared data
The Geekflare open banking intro article nicely summarizes it as:
"Banks are open to interacting with third-party providers and sharing customers‘ financial information with ease. But it’s open yet safe!"
Now that we‘ve covered the basic ideas, let‘s unpack how this works.
Understanding Open Banking Technology Stack
At the heart of open banking is API connectivity allowing apps to interface with bank data systems. But how exactly?
Here is high-level sequence when you authorize a third-party finance app using open banking:
- You provide consent to fintech app to access your accounts
- App initiates API request to bank identifying you as customer
- Bank verifies app‘s identity through client credentials and your consent
- Bank returns financial data to app per request parameters
- App leverages data to deliver customized offerings to you
Key aspects that make the above secure data sharing possible:
Standardized APIs
Banks provide access to financial data via documented open APIs instead of proprietary closed methods. These APIs are developed as per common industry-wide specifications like UK Open Banking or PSD2 standards.
This simplifies integration for third party developers to build innovative apps.
As Mike Ralfini, CIO, M&T Bank notes:
"Standardized APIs lower barriers to entry for leveraging bank data securely by external providers."
Secure Authentication
Secure user authentication and maintaining ongoing consent lies at the heart of open banking architecture.
Industry standards like OAuth 2.0 and OpenID Connect play vital role here. They allow apps to access protected APIs without ever handling user credentials.
Banks issue unique API keys to vetted apps. Apps then use OAuth libraries to request access tokens confirming identity and customer consent. This means apps never directly see your login password.
Additional security mechanisms like multi-factor authentication (MFA) provide enhanced account protection against fraudulent access.
Regulatory Mandates
In many countries, regulations are catalysts driving financial institutions to adopt open APIs:
- EU revised Payment Services Directive (PSD2)
- UK‘s Open Banking governance
- Australia Consumer Data Right
- Canada‘s Finance Dept Open Banking Review
They aim to increase customer data transparency and options in a regulated manner.
Widely followed industry groups like the OpenID Foundation also publish open banking standards many regulators mandate around security, encryption and compliance – further catalyzing consistent adoption.
Real Life Open Banking Benefits
Now that you know the foundations, let‘s cover why open banking matters for consumers like you. Benefits span:
1. Financial Data Portability
Before open banking, customers lack easy mechanisms to export financial data outside their original bank. This reduces transparency into full financial situations across accounts at different institutions.
With open banking APIs, you retain portable data access regardless where accounts reside. This makes federated analysis possible through specialized apps described next.
2. Money Management Insights
By providing holistic read access across accounts, finance apps leverage open banking to deliver superior monitoring and intelligence. For instance:
-
Spending analytics – Pinpoint expenditure patterns from comprehensive transaction history you share across credit cards, bank accounts and wallets – allowing you to budget smarter. e.g. Monzo‘s Insights
-
Portfolio tracking – Consolidated view helping analyze asset allocation, returns and risks across diverse investments in one dashboard e.g. Wealthica
-
Cash flow analysis – Assessing real-time income and outflows across accounts greatly helps planning and liquidity e.g. Moneytis
Such 360 insights around personal finances are only possible thanks to open banking fueled data consolidation.
3. Access to Personalized Services
Specialist apps leverage your shared financial history to tailor offerings specifically matched to your profile:
-
Individualized saving plans like UK‘s MoneyBox analyze income and spend patterns to create custom monthly saving schedules helping you effortlessly build wealth.
-
Pre-approved lending offers through providers like OAKNorth Bank based on cash flow health checks from your transaction history rather than manual credit checks. Minimizes delays and paperwork.
-
Fraud prevention by correlating your spending history with detection of suspicious payment anomalies – helping alert much faster.
The above demonstrate open banking fueling superior personalization of service delivery thanks to increased data visibility.
4. Enhanced Financial Options
Open banking fosters more competition and choice. Rather than relying solely on your bank‘s restrictive proprietary apps and payments platforms – you can access services from the most innovative, trusted providers via open APIs.
For instance:
-
Authorizing an expense management system like Pleo to directly access transaction feeds from business accounts held at multiple banks – removing reconciliation overheads.
-
Allowing an investment service to automatically factor daily account balances across savings and checking accounts into dynamic portfolio allocation recommendations.
This flexibility to leverage services from specialists augments capabilities compared to being locked into just one institution.
As more sectors adopt open data protocols – we‘ll see open insurance, open pensions similarly foster choice.
Global Open Banking Adoption Patterns
