A Sophisticated Approach to Data Will Be Key to Open Finance’s Success
2
By Tom Bull, UK FinTech Growth Leader, EY
Unlocking the value of open finance will ultimately come down to how newly accessible data is used; for many banks, this will require a whole new approach.
Open banking is transforming financial systems internationally. Allowing consumers and businesses to share their bank-account data securely with other institutions and authorise direct account-to-account payments opens up a broad array of new products and services that will increase competition. More than 70 countries are now on a path to open banking, including the United States, which has traditionally taken a market-led approach to customer-data sharing.
Consumers are taking notice. In the United Kingdom, for example, more than one million people paid their self-assessment tax bills using open banking in the year to January 2024, up from 140,000 the previous year.1
Today, open finance represents an expansion of open banking’s capabilities, broadening the potential datasets beyond bank accounts to include a wider range of financial products, such as investments, pensions and mortgages, all personalised and often cheaper.
Consumer demand for products based on these new capabilities is strong. Research conducted by EY (Ernst & Young) and The Investing and Saving Alliance (TISA) found that 90 percent of consumers would be likely to use open finance-based dashboard applications that provide a consolidated view of their finances.2 The innovation is also relevant to small and medium-sized enterprises (SMEs), providing support as they manage their cashflows and connect banking data to cloud accounting packages.
However, implementing and adapting to open banking and open finance is a huge task for banks. As customers gain greater control of their financial data and can share it more freely, banks need to ensure they continue to adhere to the same high security standards.
This is a profound shift for banks, which have traditionally built their systems solely to ensure customer data is protected without giving much consideration to interoperability. Maintaining high levels of protection while allowing data to be shared represents a major change in approach.
So, seizing the opportunities that open finance presents could be transformative for banks, and for those that can successfully navigate the risks, the upside is enormous. Inaction from banks will only serve to heighten competition from technology firms with presences in the financial-services space.
Building for the future
Taking advantage of open finance requires banks to fundamentally change their approaches to data. Today, operations across many banks are underpinned by legacy, closed-architecture systems that were never designed for easy integration with third parties.
Simply maintaining the status quo requires huge amounts of work. EY research indicates that financial institutions currently spend up to 65 percent3 of their information technology (IT) budgets on maintaining current systems rather than innovating and developing new propositions.
These legacy platforms and processes constrain agility, hindering banks’ ability to get products to market and stay ahead of evolving customer needs.
To set themselves up for success, banks need to invest in areas more typically associated with technology platforms. This includes prioritising areas that may be unfamiliar, such as:
- Application programming interface (API) channels that are fast, secure and reliable, making it easy to connect with other companies and share customer data (with permission). Speed is crucial here, as fast response times are critical for smooth user experiences, especially for products that aggregate data from many sources in one place.
- Great developer experience to encourage others to engage with the bank’s API. This requires building easy-to-use software development kits (SDKs), as well as providing documentation, tools and community support for developers.
- A commercial model underpinning the bank’s open banking strategy that recognises the needs of both the bank itself and the companies that hope to partner with it. This should be driven by a strong sales organisation that can actively promote the bank’s API to potential partners and drive usage.
As open finance gains momentum, banks and other financial institutions will be required to handle a far greater volume of data than ever before. By taking the necessary steps to improve their data infrastructures, they will be better positioned to succeed in the future.
Looking at data in new ways
Open finance creates a novel situation for banks, enabling them to become consumers of datasets to which they have never had access before. This presents opportunities to launch new product offerings and engage with customers in new ways, as long as they are able to access, utilise and exploit the new data fully.
Many of these opportunities revolve around new ways to gain a better understanding of existing customers by using new data sources to build more complete views of their overall financial pictures.
An enhanced data picture can also make it possible to offer a wider range of products to existing customers. For example, an estimated five million people in the UK are currently considered “thin-file”, meaning they have little or no credit history.4 For people in this group, accessing loans can be prohibitively expensive or even impossible, even if they earn a good wage and are financially responsible.
Open finance allows banks to view a wider array of data sources to assess creditworthiness—for example, transaction data to understand spending patterns and budgeting. This has the potential to open up access to credit to a much broader population.
Adaptation will be a three-step process
The possibilities offered by open finance are expansive and can be overwhelming. Banks need to be selective about the use cases and customer segments they target. With this in mind, adapting should be approached as a three-step process.
The first step is screening. A bank should take the time to understand the new capabilities on offer, not just through access to new data sources but also regarding its ability to trigger payments from within a customer’s account, bypassing traditional payment gateways and networks.
These capabilities and the new data sources available should then be screened for commercial-opportunity size, operational complexity and the priorities of the business unit, as well as the costs and technical complexity of deployment.
Having built a shortlist, the next step is to begin building out business cases and testing the propositions with customers to test demand and refine the offering.
The challenge during this phase is striking the right balance between protecting existing business lines against cannibalisation while simultaneously testing potentially transformative products. Pay-by-bank payments, for example, have the potential to cannibalise revenues from card payments, but banks must be willing to disrupt their own business models before someone else does.
As new products are developed and brought to market, the third step, customer education, will be key. People will not use financial products if they do not understand the benefits, so banks must enable customers to understand how these new capabilities can improve their financial lives.
Open finance should be seen as an opportunity for banks to engage more deeply with their customers and serve them in better ways. Harnessing it will require an evolution in approach but could unlock incredible growth for the banks that embrace it.

Morgan Stanley sees writing on wall for Citi before major change
Banks have had a stellar first quarter. The major U.S. banks raked in nearly $50 billion in profits in the first three months of the year, The Guardian reported.
That was largely due to Wall Street bank traders, who profited from a volatile stock exchange, Reuters showed.
But even without the extra bump from stock trading, banks are doing well when it comes to interest, the same Reuters article found. And some banks could stand to benefit even more from this one potential rule change.
Morgan Stanley thinks it could have a major impact on Citi in particular.
Upcoming changes for banks
To understand why Morgan Stanley thinks things are going to change at Citi, you need to understand some recent bank rule changes.
Banks make money by lending out money, which usually comes from depositors. But people need access to their money and the right to withdraw whenever they want.
So, banks keep a percentage of all money deposited to make sure they can cover what the average person needs.
But what happens if there is a major demand for withdrawals, as we saw during the financial crisis of 2008?
That’s where capital requirements come in. After the financial crisis, major banks like Citi were required by law to hold a higher percentage of money in order to avoid major bank failures.
For years, banks had to put aside billions of dollars. Money that couldn’t be lent out or even returned to shareholders.
Now, that’s all about to change.
Capital change requirements for major banks
Banks that are considered globally systemically important banking organizations (G-SIBs) have a higher capital buffer than community banks as they usually engage in banking activity that is far more complicated than your average market loan.
The list depends on the size of the bank and its underlying activity, according to the Federal Reserve.
Current global systemically important banks
A proposal from U.S. federal banking regulators could drastically reduce the amount that these large banks have to hold in reserve.
Changes would result in the largest U.S. banks holding an average 4.8% less. While that might seem like a small percentage number, for banks of this size, it equates to billions of dollars, according to a Federal Reserve memo.
The proposed changes were a long time coming, Robert Sarama, a financial services leader at PwC, told TheStreet.
“It’s a bit of a recognition that perhaps the pendulum swung a little too far in the higher capital requirement following the financial crisis, making it harder for banks to participate in some markets,” he said.

Couple forced to live in caravan buy first home as ‘stars align’ in off-market sale
Natasha Luscri and Luke Miller consider themselves among the lucky ones. The couple recently bought their first home in the northwest suburbs of Melbourne.
It wasn’t something they necessarily expected to be able to do, but some good fortune with an investment in silver bullion and making use of government schemes meant “the stars aligned” to get into the market. Luke used the federal government’s super saver scheme to help build a deposit, and the couple then jumped on the 5 per cent deposit scheme, which they say made all the difference.
“We only started looking because of the government deposit scheme. Basically, we didn’t really think it was possible that we could buy something,” Natasha told Yahoo Finance.
RELATED
Last month they settled on their two bedroom unit, which the pair were able to purchase in an off-market sale – something that is becoming increasingly common in the market at the moment.
Rather perfectly, they got it for about $20-30,000 below market rate, Natasha estimated, which meant they were under the $600,000 limit to avoid paying stamp duty under Victoria’s suite of support measures for first home buyers.
“They wanted to sell it quickly. They had no other offers. So we got it for less than what it would have gone for if it had been on market,” Natasha said.
“We didn’t have a lot of cash sitting in an account … I think we just got lucky and made some smart investment decisions which helped.”
It’s a far cry from when the couple couldn’t find a home due to the rental crisis when they were previously living in Adelaide and had to turn to sub-standard options.
“We’ve managed to go from living in a caravan because we were living in Adelaide and we couldn’t find a rental with our dogs … So we’ve gone from living in a caravan, being kind of tertiary homeless essentially because we couldn’t get a rental, to now having been able to purchase our first home,” Natasha explained.
Rate rises beginning to bite for new homeowners
Natasha, 34, and Luke, 45, are among more than 300,000 Australians who have used the 5 per cent deposit scheme to get into the housing market with a much smaller than usual deposit, according to data from Housing Australia at the end of March. However that’s dating back to 2020 when the program first launched, before it was rebranded and significantly expanded in October last year to scrap income or placement caps, along with allowing for higher property price caps.

WHO says its finances are stable, but uncertainties loom – Geneva Solutions
A year after the US exit from the global health body, WHO officials say finances are secure, for now. But amid donor cuts, rising inflation, and future economic uncertainties, will funding be sufficient to meet its needs?
Earlier this month, senior officials at the World Health Organization (WHO) told journalists in a newly refurbished pressroom at the agency’s headquarters that its finances were “stable”. Following a year that saw its biggest donor withdraw as a member, forcing it to cut 25 per cent of its staff, its financial chief said that 85 per cent of its 2026 and 2027 budget had been financed.
“While we are looking at resource mobilisation, we’re also looking at tightening our belts,” Raul Thomas, assistant director general for business operations and compliance, explained, admitting that the WHO “will have great difficulty mobilising the last 15 per cent”.
Sitting at the centre of the press podium, surrounded by his deputies, Tedros Adhanom Ghebreyesus, WHO director general, backed up Thomas’s outlook. “We are stable now and moving forward”, since the retreat of the United States from the health body, he said. The Ethiopian noted that the WHO’s financial reform, allowing for incremental increases in state member fees, has been a big plus.
Mandatory contributions have historically accounted for only a quarter of the organisation’s total funding. States have agreed to raise their contributions by 20 per cent twice, in 2023 and in 2025. Further increments are scheduled to be negotiated in 2027, 2029 and 2031 to bring mandatory funding up to par with voluntary donations that the agency relies on. The WHO also reduced its biennial budget for 2026 and 2027 from $5.3 billion to $4.2bn.
“Our financing actually is better,” Tedros emphasised. “Without the reform, it would have been a problem.”

Nonetheless, the director general, now in his final year at the UN agency, warned that member states should not assume that the financial road ahead will be clear. “The future of WHO will also be defined by how successful we are in terms of the assessed contribution increases or the financial reform in general.”
As west retreats, others step in
Suerie Moon, co-director of the Global Health Centre at the Geneva Graduate Institute, explains that every year at the WHO, there’s “a non-stop effort” to ensure funding. She says a continued reliance on non-flexible, voluntary funding earmarked for specific projects, as well as donors withholding contributions – sometimes for political leverage – complicates the organisation’s financial plans. Meanwhile, ongoing cuts and predictions of a global economic downturn stemming from the war in the Middle East may further aggravate the situation, as costs rise and member states focus on national spending needs.
Soaring prices driven by the conflict and supply chain disruptions have already affected the WHO’s procurement of emergency health kits for crises, officials at the global health body said. “We are continuing to negotiate at least from a procurement standpoint on how we can bring down a little bit the prices or reduce the increases, but we are seeing it across the board,” said Thomas.
Altaf Musani, WHO director of health emergencies, meanwhile, said aid cuts have already deprived roughly 53 million people in crisis situations of access to healthcare.
Last month, Thomas told the Association of Accredited Correspondents at the UN at the end of April that the agency is looking at non-traditional, or non-western, donors for funding to close the biennial 15 per cent funding gap. “It’s not that we won’t go to the traditional donors, but we’re expanding that donor base.”
Since the dramatic drop in funding from the US, formerly the WHO’s biggest contributor, Moon highlights that there hadn’t been a “sudden jump by non-traditional states to compensate for the US”. Last May, at the World Health Assembly, China pledged $500 million in voluntary funding until 2030, a sharp rise from the $2.5m it contributed over 2024 and 2025.
The WHO did not respond to questions from Geneva Solutions about how much of the pledged amount had been disbursed. China’s mission in Geneva did not respond to questions raised about the funding.
Other countries, particularly Gulf states, have meanwhile been increasing their voluntary contributions to the organisation in recent years. Similarly to “western liberal democracies have in the past”, Moon explains that they may be seeking “to raise their profile and prioritise health as one of the issues that they would like to be known for”. She noted that the shift in the UN agency’s list of top donors may affect how it manages the money.
‘Sustainable’ spending
Amid these financial uncertainties, WHO executives say the organisation is also reviewing its expenditure through “sustainability plans”. This includes working more closely with collaborating centres, including universities and research institutes that support WHO programmes and are independently funded. On influenza, for example, the WHO works with dozens of national centres around the world, including the Centers for Disease Control and Prevention in the US,
When asked about any plans for further job cuts, Thomas denied that these were part of the WHO’s current strategies, but could not rule them out entirely as a future possibility. Instead, he said, the organisation was “looking at ways to use funding that may have been for activities to cover salaries in the most important areas”.
Meanwhile, WHO data shows that the number of consultants employed by the agency by the end of 2025 decreased by 23 per cent, slightly less than the staff reductions. Global heath reporter Elaine Fletcher explained to Geneva Solutions that consultants continue to represent a significant proportion of the agency’s workforce, at 5,844 – including an overwhelming number hired in Africa and Southeast Asia – compared with regular staff numbering 8,569 in December.
Upcoming donor politics
The upcoming change in leadership will also be a strategic moment for the organisation to boost its coffers. Moon says the race for the top job at the organisation may attract funding from candidates’ home countries, which could be seen as a strategic opportunity.
Given the relatively small size of the WHO budget, compared to some government or agency accounts, “you don’t have to be the richest country in the world to dangle a few 100 million dollars, which could go a long way in their budget,” the expert notes.
The biggest ongoing challenge, however, will be whether major donors will announce further aid cuts. In the medium and longer term, “countries will have to agree on the step up every two years, and there’s always drama around that.”
