The adoption of open banking is leading to innovation across financial solutions such as account-to-account payments (A2A), personal finance management (PFM) apps, embedded finance, and banking-as-a-service (BaaS) by enabling real-time data-driven insights and personalized financial services. It is paving the way for a more dynamic financial landscape. Open banking has evolved rapidly since the revised Payment Services Directive (PSD2) came into force in Europe. While challenges exist, adopting open banking solutions, aided by introducing regulatory and security measures, holds the potential to revolutionize the financial services sector.

The introduction of APIs transformed banking services

Open banking has emerged as a transformative force, changing how financial data is shared, and services are offered to consumers. It securely provides third-party financial service providers access to consumer’s financial information with their consent through an application programming interface (API). It aims to foster innovation in financial services, encourage healthy competition, and give consumers more control over their banking information. Several banks across countries, including Citi, Barclays, and Deutsche Bank, have started providing access to their APIs.

Regulatory initiatives and consumer demand lead to open banking growth

While open banking has existed for a long time, it gained traction when the PSD2, a European regulation focused on creating a more open, competitive, and secure payment landscape across Europe, came into effect in 2018.

Since then, several countries have introduced open banking regulations to support its adoption. For instance, in the UK, the open banking initiative, led by the Competition and Markets Authority (CMA, the UK’s principal authority responsible for strengthening business competition and preventing anti-competitive activities), became effective in 2018. In addition to the European countries, Australia, New Zealand, Brazil, and South Africa, among others, have introduced regulatory measures to drive the adoption of open banking.

Countries across the globe are adopting various approaches to open banking, including regulatory-led, market-led, and hybrid approaches. While Europe has taken a regulatory-led approach, adopting open banking in the USA, Canada, and China is driven by consumer demand and technological innovations. Consumers prefer to have control and transparency over their financial data. While there are currently no regulatory frameworks for open banking in the USA, the Consumer Financial Protection Bureau (CFPB) has proposed rules to protect consumer data rights, which will aid in facilitating the adoption of open banking.

Several countries, such as India, South Korea, Japan, Hong Kong, Russia, and Singapore, have adopted a hybrid model, including both regulatory and market-led initiatives. These countries do not have mandatory open banking regimes, but policymakers are looking to introduce initiatives to accelerate open banking adoption. For instance, in Singapore, the Monetary Authority of Singapore (MAS) and the Association of Banks have published an API playbook. This publication aims to support data exchange between banks and fintech players.

The growing emphasis on introducing regulatory measures to ensure data security will likely drive the adoption of open banking.

Open banking is driving innovation in financial solutions

The adoption of open banking is transforming financial solutions, including A2A payments, variable recurring payments (VRP), PFM apps, BaaS, and embedded finance, by enabling faster, more convenient, secure, and personalized financial services.

A2A payments and VRP

Open banking allows secure access to real-time bank data to third-party providers, enabling process automation, speeding up A2A payment transfers, and providing a better user experience. Increasing adoption of open banking globally is expected to make international A2A payments more viable and secure.

Digital wallet platforms such as Apple Pay, Google Pay, and Stripe are looking to integrate open banking on their platforms to provide enhanced user experience. In September 2023, Apple soft-launched a new iPhone wallet app in the UK integrated with an open banking framework to replace traditional banking apps as the preferred platform for accessing information related to their account balance, spending history, etc.

Open banking also encourages the widespread adoption of variable recurring payments by giving consumers more transaction control and transparency. The use of variable recurring payments is expected to increase across various commercial payment services, such as utility bills, subscriptions, and insurance premiums, in the coming years.

PFM apps

Access to financial data enables PFM apps to share more effective and personalized financial advice with consumers. A real-time snapshot of the overall financial health of the consumers helps them make long-term financial decisions.

BaaS

Banking-as-a-service platforms are likely to develop due to the adoption of open banking, allowing non-banking entities to provide financial services without becoming certified banks. This offers consumers a variety of payment and credit options, as well as more personalized finance solutions, expanding the industry offering.

Integrating BaaS in retail is being explored to improve customer loyalty programs and provide seamless payments. Also, the scope of services is likely to expand rapidly, from offering banking services to individual consumers to small and medium-sized enterprises (SMEs) and large corporations in the near future.

Embedded finance

Open banking has become the driving force behind the rise of embedded finance, enabling businesses and corporate clients to enhance operational efficiency and user experience. While retail and e-commerce platforms are some of the first to adopt embedded finance, the adoption is likely to increase in less digitalized spaces such as real estate as well.

Synergy with AI and blockchain offers scope for advanced innovation and security

Open banking provides a data-rich environment by aggregating data from various financial institutions for AI algorithms to analyze and utilize for decision-making. It is expected to benefit AI algorithms further by incorporating new features such as data categorization and anomaly detection in the coming years.

On the other hand, AI is likely to increase the effectiveness of open banking by analyzing individual consumer data and enabling the offering of personalized services. AI and open banking will likely help financial institutions develop innovative products.

While both AI and open banking complement their financial services, they can lead to data misuse or unauthorized access concerns, highlighting the need for strong regulatory measures to keep up with the evolution of open banking and AI.

Blockchain technology will likely become more common in open banking as it will enhance the security and transparency of financial transactions. It will likely reduce the risk of data breaches and unauthorized access to consumers’ finances. Additionally, it will likely make it easier for consumers to share their data by simplifying the authentication and consent processes.

Open banking services have expanded from basic payment initiation to open finance

The open banking framework has evolved from basic account information and payment initiation services to open finance, including access to data from various accounts, including savings, investments, pensions, insurance, and mortgages.

Countries such as India, South Korea, Australia, and Brazil have moved from open banking to open finance to develop a more connected financial ecosystem. In February 2024, South Korea also introduced two initiatives focused on including business data and providing offline open banking services.

In Europe, the European Commission is also pushing towards open finance by introducing the Financial Data Access (FiDA) regulation, a framework to enable secured sharing and access of financial data.

Open banking will diversify consumer options, with non-financial companies such as telecom providers, e-commerce platforms, and utility companies offering innovative financial products. They will likely enter into partnerships with banks to provide integrated services to consumers, enhancing their offerings and creating an interconnected financial ecosystem.

Lack of standardized APIs affects the open banking adoption

While open banking is gaining traction, specific challenges, such as lack of standardized APIs, integration with legacy systems, privacy compliance, and data security, are affecting its adoption.

The lack of standardization of APIs across financial institutions is the key challenge in adopting open banking. Third-party providers are usually unable to adapt to different APIs and provide seamless data sharing between systems.

Various financial institutions also face difficulty integrating open banking into their legacy systems, making the integration process complex and expensive. Banks must first update their systems by investing in technology upgrades and partnering with fintech solutions providers to overcome integration challenges.

As the adoption of open banking increases, the chances of data breaches might also increase, highlighting the need to protect customer data and compliance with privacy regulations. Banks are looking to adopt measures such as encryption, clear usage policies, and regular audits to protect customer data. The European Union has also put regulations such as the General Data Protection Regulation (GDPR) and the Digital Operational Resilience Act (DORA) in place to protect customer data and improve the digital security of financial institutions. Advanced security measures solutions, including tokenization and dedicated API gateways, can also help safeguard customer data.

Lack of awareness among consumers is another key challenge. Users are often unaware of open banking and are reluctant to share their financial data due to privacy concerns. Initiatives aimed at educating the users about security and regulatory norms related to open banking by banks can help overcome this challenge and drive adoption.

EOS Perspective

The shift to an open banking model can transform the future of digital banking. The key driving factors for the users are the ease and clarity of the interface, which are likely to replace the traditional banking infrastructure and ownership of consumer data.

The expected introduction of PSR1 in 2026 will likely improve competition and consumer protection in the payments market, which will likely drive the adoption of open banking. PSR1 will help enhance fraud prevention, improve consumer rights and protection, standardize payment regulations, and enhance open banking functions.

The introduction of regulatory and security measures and growing awareness about open banking and its benefits are also likely to aid this growth. A phased implementation of open banking will help with greater adoption of open banking by gradually introducing the concept to the consumers and helping them adapt.

Open banking will benefit banks by providing better customer insights, encouraging innovation, and creating an additional revenue stream through API monetization. However, increasing competition from fintech and non-financial institutions entering the market will likely pressure banks to transition to open banking. The shift to open finance will further increase the competition in the industry. We will likely witness banks entering partnerships with fintech players to develop and offer innovative financial services for their consumers.

The financial sector is embracing open banking as a means to offer creative and innovative financial solutions to enrich the user experience. Open banking will likely evolve into a broad ecosystem of connected services, streamlining the consumers’ products, services, and applications into one, providing a seamless experience.
