Introducing Open Banking

Open Banking is an industry term that’s often misunderstood. We explain more about what it is, where it came from and how it’s disrupting payments.

What is Open Banking?

Open Banking describes a way of securely sharing data held by banks, if customers consent to this. Some countries mandate a standardized format for this data-sharing.

Better bank payment is just one of the stand-out use cases of Open Banking. This connects customers to their bank accounts locally so they can pay sellers worldwide in seconds.

Open Banking payments are not only speedier, simpler and safer for consumers. They also help e-commerce merchants boost conversion, customer satisfaction and cost savings.

Where did Open Banking come from?

Open Banking was introduced in the EU and UK in January 2018, originally as a regulatory initiative to improve competition in banking and payments.

The revised payment services directive, or PSD2, regulates how Open Banking is implemented in the EU and EEA. However, the reach and scope of Open Banking is expanding.

Banks and authorities in Australia, Brazil, Canada, India, Hong Kong, Singapore, the US and more are actively exploring Open Banking opportunities.

Meanwhile the scope is growing to include financial data around savings, loans, pensions and insurance for more of an Open Finance proposition.

What problems does Open Banking solve for PSPs and their customers?

Open Banking tackles various intractable payment problems that PSPs and their customers face head on:

  • Coverage – the reach of Open Banking is potentially anyone with a bank account. No subscriptions or additional on-boarding via intermediaries are needed.
  • Cost – it’s cheaper than card payments with no ad valorem interchange fees, chargebacks PCI DSS costs.
  • Adoption – the consistent, intuitive UX of Open Banking helps to boost adoption and success rates for bank transfers done better.
  • Fragmentation – using existing infrastructure gives sellers access to thousands of banks and customer accounts through a single integration. And enables payers to make local bank payments to thousands of sellers worldwide.
  • Security – it’s based on bank-grade security without cumbersome 3DS processes, or the exchange of sensitive card data, putting transactions in scope of PCI DSS.

How is Open Banking being used?

Open Banking is the technical rails on which providers run services, so there are countless possibilities for new products and solutions. Here are just three use cases:

Payments – making it possible for sellers to accept payment direct from customers’ local bank accounts quicker, easier and better than ever before.

Financial management – providing a more joined-up view of money, making it easier for consumers and businesses to manage their finances. And enabling providers to tailor products and services better.

Know your customer – helping providers know their customers better, which presents new opportunities around verifying accounts, identities and affordability. This improves access to service and capital as well as management of risk and more.

Why get involved in Open Banking now?

Several overlapping trends are driving the interest in and uptake of Open Banking. Payment volumes and values are growing as a result.

At the same time, your customers, whether they are large e-commerce retailers, iGaming operators or banks, want to hold on to their customers and own those relationships. They want to compete strongly in the digital remittance and pay-in/pay-out space.

Open Banking is embedded into the financial system. And transformation of cross-border payments has already started. It’s time to get on board and develop your own compelling propositions, tailored to particular use cases, customer segments and payment corridors.

Drivers of Open Banking

Bank account-funded payments have always been popular, especially in Europe. They’re what customers know and feel comfortable with. However, several overlapping trends are turbo-charging the interest and reach of Open Banking.

  • Connected customers – today’s customers are increasingly connected via mobile, smart watches, speakers etc. They lead busy, on-the-go lives and expect speed, convenience, value and choice as the default. And are known to move to providers for a better solution or UX.
    With Open Banking payments, there’s no need to top up wallets or type in card details on the tiny keyboard of a mobile device. The UX is slicker and quicker than cards. It’s also easier than logging into online banking and manually go through the payment process step-by-step.
  • Covid kick-start – the global pandemic changed how people bank, shop, meet, date, game and more. Friction-free, digital-first journeys are now must-haves.
    Open Banking plays to this by giving consumers a better way to make local bank payments to sellers globally. It gives sellers access to hundreds, if not thousands, of banks and customer accounts through a single integration.
  • Rise in real-time – there were 64 live real-time payment schemes globally in 2022, accounting for nearly $525 billion in e-commerce transaction value. This is set to grow at a CAGR of 13% through 2026.
    Real-time payments will transform speed of payment for consumers. But also settlement and certainty of payment for sellers, with all the extra benefits around cashflow and working capital efficiencies.
  • Payment as an operating systemevery company will be a fintech company, according to venture firm Andreessen Horowitz. This means more opportunities to embed financial services and payment at the point of need. But also, more new entrants who don’t necessarily have a finance background.
    Opportunities as well as possible disintermediation threats for incumbents exist in the same future. Open Banking is a great alternative to cards and direct debits, especially for cross-border sales. And a great way to embed bank-funded financing in all types of use cases.
