Open Banking—far more than PSD2

Open Banking refers to the practice of securely sharing financial data, subject to customer consent. The exchange of data between the bank and authorized third parties (such as financial institutions, fintech companies and enterprises that are not necessarily active within the financial sector at present) is enabled via so-called Application Programming Interfaces, in short “APIs”.

This drastic reduction of data barriers within the banking industry will lead to significant product and service innovations, improvements in cyber security, and will ultimately simplify the customer journey. Open Banking is therefore part of a broader trend toward sharing data and eliminating barriers to data access while increasing the customers’ control over their data.

The evolution of Open Banking

Open Banking emerged from the EU PSD2 regulation, whose original intent was to introduce increased competition and innovation into the financial services sector. PSD2 forces banks to offer dedicated APIs for securely sharing their customers’ financial data for account aggregation and payment initiation. Although PSD2 does not require a specific open standard, it sets a legal framework within which both the UK’s and the EU’s Open Banking standards (e.g. STET, Berlin Group) have to operate.

PSD2, however, is not the only trend forcing a shift of the sector towards Open Banking. We identify four general industry trends forcing incumbents to revise their business models in order to maintain their current market positions.

The combination of these four trends has resulted in the phenomenon that we call Open Banking.

Impact along three dimensions

Open Banking is much more comprehensive than PSD2; it is a systematic paradigm shift in the way financial services are delivered along the entire value chain. We believe that the impact can be felt along three dimensions and will cause significant changes in banking ecosystems, platforms and portals.

  1. Product and service offerings
    Will Open Banking result in a modularized product and service offering, i. e. some level of specialization, or will we continue to see full product and service offerings from established players within the future market?
  2. Industry concentration
    Will Open Banking result in a single EU-wide dominant platform, which, due to winner-takes-all effects, other financial services providers will be forced to use, or will multiple players and platforms be able to coexist in the future market?
  3. Players
    Will Open Banking allow non-bank players such as big techs (Apple, Facebook etc.) to enter the market, or will the traditional banks succeed in maintaining their market dominance in the financial services sector?

The direction along each of these axes must be carefully observed and can be influenced by multiple factors. Banks will be able to aggregate and distribute their (customer) data and services beyond the regulatory requirements in order to enrich their own product portfolio.


Banks and non-banks will be able to benefit from new partnerships and a broader base of accessible data from other financial and non-financial service providers by offering new value-added services to their customers. Services they do not have to build or run themselves.

Open Banking also enables banks to build relationships with external developers, which leads to a better understanding of both the market and the end users and also allows them to make smarter decisions about products and channels.

In summary, the PSD2 was brought to life to increase the competition in the financial services industry, but Open Banking reaches far beyond. It starts with a continuous improvement in customer centricity and leads to an increased financial integration with value-added services and further improvements such as the reduction of overdraft fees. It is clear that Open Banking will continue to change the classic bank-customer relationship and the banking business in general, long after PSD2 is in place.
