A Roadmap for Fintechs and Financial Institutions
THE NEW DATA REALITIES IN BANKING
Scott Harkey, chief strategy officer and head of payments at payments consultancy Levvel, wrote recently in Forbes:
鈥淚t has been stated many times that data is the key to unlocking the next wave in financial services. In the last decade, we鈥檝e seen this play out in countries across the globe to various degrees; some have legislated openness of financial services data between different institutions and service providers, while others, like the U.S., have approached things more cautiously. Regardless of the method, the financial services ecosystem is evolving in a way that encourages the opening up of data sources previously locked down inside large organizations.鈥
The discussion about open banking and open finance in the United States typically revolves around statements like, 鈥淲e need to enable consumers to move their data wherever they want.鈥 Much of the conversation, however, ignores how data is shared and for what purposes. The most common use case is account verification, and data is typically shared one of three ways:
- Tokenized APIs. Industry associations like FDX are working to standardize application programming interfaces (APIs), while data platforms from companies like 糖心传媒 and Plaid are developing libraries of open-source API documentation that matches FDX guidelines to help financial institutions connect without having to develop their own APIs.
- Screen scraping. This is fast becoming an unacceptable approach because regulations in some countries prohibit it, there is a lack of traceability, data quality isn鈥檛 very strong, and there are security concerns, particularly around sharing login credentials.
- Manual data entry and verification through microdeposits. Speed of the process is the biggest drawback here as it can typically take one to three days to verify an account.
What鈥檚 a bank to do? Scarlett Sieber, chief strategy and growth officer for Money 20/20, wrote in Forbes:
鈥淔or many U.S. financial institutions, the starting point to open banking and API enablement will be their core provider. Currently, the three leading providers in the U.S.鈥擣IS, Fiserv, and Jack Henry鈥攁re creating API gateways that expose the data and functionality inside of their core systems, allowing banks to easily work with third parties.鈥
Jim Marous, CEO of the Digital Banking Report, isn鈥檛 so sure about that. According to Marous:
鈥淩esearch of financial institutions indicates that core providers are not regarded as ready to support the technical or innovation needs for the development of open banking solutions.鈥
Digital Banking Report found that most financial institutions see open banking as an important contributor to a wide range of business objectives including customer experience improvement, new customer generation, new revenue generation, and new product development (Figure 1).

While the term may be overused and misused, banking industry constituents鈥攚hich include financial institutions, fintechs, and end customers (whether they be consumers or businesses)鈥攈ave three underlying needs regarding open banking: the need to 1) acquire, 2) use, and 3) analyze data.
The common thread that runs through those three needs is the reliance on third-party partners or vendors (sometimes referred to as data aggregators) to meet those needs. No single financial institution or fintech鈥攅ven the largest banks in the United States鈥攃an create and manage the connections necessary to accomplish the promise of open banking.
The goal of this report is not to preach the need for open banking, however. The goal is to help financial institution and fintech executives make smart choices about which partners or vendors they use to meet their data acquisition, utilization, and analytical needs.
Making these choices will require financial institutions and fintechs to make tough decisions about their 1) strategy in a changing industry, 2) the role they need to and want to play in a highly interconnected network of providers, and 3) the business and technical capabilities they need to build to operate in the ecosystems in which they participate.聽
THE OPEN BANKING IMPERATIVE
Conventional wisdom holds that open banking in the United States is lagging. According to an American Banker article titled 鈥淯.S. way behind the curve on open banking鈥:
鈥淧olicymakers, fintech companies, and financial services firms are finally beginning an earnest dialogue about open banking. It鈥檚 good because the U.S. has a lot of catching up to do. In the U.S., there鈥檚 no legal requirement stipulating a financial institution must make a consumer鈥檚 financial data available to a third party if a consumer provides affirmative consent.鈥
The rationale for that view is often supported with meaningless consumer survey statistics like this one from the American Banker article:
鈥淐onsumers have demonstrated their desire for open banking. 87% of individuals prefer to adopt a fintech app rather than use a product or service offered by a traditional financial services provider.鈥
How does that data point demonstrate a desire for 鈥渙pen banking?鈥 If consumers prefer a fintech app to a traditional provider鈥檚 products and services, then why would traditional firms need to share data? In addition, fewer than 87% of consumers do their banking on a mobile device today, so it鈥檚 hard to believe that that many consumers would prefer a fintech app to their traditional bank account.
Instead of embracing the benefits of open banking, U.S. banks have fought against it and the data aggregation providers that have worked to enable it. As the CEO of a North American bank recently expressed:
鈥淚 truly believe it is my data and I don鈥檛 have to share it, and I don鈥檛 have to give it to my customers if I don鈥檛 want to.鈥
However, this anti-competitive attitude is increasingly at odds with the sentiments of consumer advocates who preach that consumers should own and be in control of their own data, and with regulators like the Consumer Financial Protection Bureau (CFPB), which views open banking as a critical tool for leveling the competitive playing field:
鈥淲e can only accrue the benefits of competition if customers can vote with their feet. Unfortunately, switching bank accounts isn鈥檛 easy. It involves new account numbers, new debit cards, updating direct deposit, updating auto-debits, and much more. If America can shift to an open banking infrastructure, it will be harder for banks to trap customers into an account for the purpose of fee harvesting.鈥
CONSUMERS鈥 INCREASINGLY COMPLEX FINANCIAL LIVES
But consumers aren鈥檛 鈥渧oting with their feet.鈥 The new reality is that fintechs co-exist with鈥攏ot replace鈥攖raditional providers. It鈥檚 not uncommon for a young couple to do business with 30 to 40 financial providers (Figure 2).

This picture doesn鈥檛 even include consumers鈥 insurance relationships or the borrowing side of the coin, where many consumers have student loans, car loans, mortgages, and other personal loans. And you can bet that they don鈥檛 have all those loans with one provider.
The result: consumers鈥 financial lives have become more complex. What are the implications of consumers鈥 new, complex financial lives?
- Financial products鈥攏ot the banks鈥攈ave been unbundled. There was a graphic from CB Insights that became popular a few years ago (you don鈥檛 really want to see it again, do you?) titled, 鈥淭he unbundling of a bank.鈥 Pithy, but it missed the point鈥攊t鈥檚 the product that鈥檚 been unbundled, not the institution.聽
- Financial advice and guidance have been compromised. As personal financial management (PFM) and credit management tools have been unbundled from checking account and credit cards, consumers鈥攁nd their providers鈥攇et an incomplete view of their finances. This means consumers are making financial decisions based on incomplete data, but just as damaging is the fact that financial institutions鈥 advice and guidance are also based on incomplete data, making it wrong and potentially harmful.
- Primary status is meaningless. Ask a Gen Zer or Millennial who their primary financial institution is and you鈥檙e likely to get a blank stare. They may have a primary checking account or primary investment account, but that doesn鈥檛 guarantee any wallet share for the provider of that account. Likewise, 鈥渢op of wallet card鈥 status is no longer a valid concept. Point-of-transaction convenience and value drive choice of payment mechanism.
- Managing money is more important than moving money. Of 鈥渂uy now, pay later鈥 (BNPL) users who have been late with a payment, 66% were late because they lost track of the bill due date. Among the 45% of Millennials with more than one checking account, about half overdrew on those accounts in 2020. For most of them, it was because they failed to keep track of their account balance or didn鈥檛 transfer funds from other accounts in time鈥攏ot because they didn鈥檛 have the money. Conclusion: today鈥檚 consumers need more help managing their money鈥攁nd they need the ability to manage and view their entire financial life in one place.
A Morning Consult study found that just 45% of Americans said they鈥檝e heard of open banking and 63% are worried that increased data sharing will lead to more fraud. The study was conducted before President Biden鈥檚 July 2021 executive order about which Bloomberg Law wrote:
鈥淸Biden] gave a boost to Consumer Financial Protection Bureau鈥檚 decade-long effort to kickstart open banking in the U.S. when he signed an executive order last week aimed at boosting competition in the economy. The president鈥檚 executive order includes a provision that strongly encourages the CFPB to issue Dodd-Frank Act regulations that would make it easier for consumers to access their bank data and transfer it to other banks and outside apps, such as Venmo or Robinhood.鈥
The real impact of the executive order is likely to be more contractual than technological. It will enable data sharing constituents to rely on data standards instead of the one-off developed contracts and agreements that dominate the industry today.
This fragmentation of consumers鈥 financial lives increases the urgency for financial institutions to create鈥攅ither by building or buying鈥攐pen banking data aggregation capabilities. Without these capabilities, they鈥檙e left with an increasingly narrow view into their customers鈥 financial lives, which makes it more difficult to provide those customers with financial advice and relevant cross-sell offers.
The imperative for open banking is growing. As the financial services industry embraces open banking and works with third-party data aggregators to create new capabilities and offerings, it will need to address an important question: How should financial institutions select an open banking data aggregation vendor?聽
SELECTING AN OPEN BANKING VENDOR
Selecting a technology vendor is as much art as it is science.
This is especially true in the open banking data aggregation market because the market itself is relatively immature. It鈥檚 only existed for a couple of years. There are no RFP templates for selecting a data aggregation vendor and few (if any) contract negotiation services specializing in open banking or open finance.
Compared to decisions regarding established technology vendors鈥攍ike a core apps provider or credit bureau鈥 deciding which data aggregator to use can feel a lot like stumbling around in a dark room without a flashlight.
To better understand how to make a smart open banking data aggregation vendor decision, Cornerstone Advisors spoke with bank and fintech executives who have gone through the process of evaluating open banking data aggregation vendors.
We鈥檝e distilled the hard-earned wisdom of these executives 鈥 which was shared with us candidly and anonymously 鈥 into six recommendations for banks and fintechs to follow when embarking on this selection decision (Figure 3).
