As Interest Rates Fall, Will Digital Banks Thrive or Struggle? Discover the Key Strategies Shaping Their Future

As global central banks adjust interest rates, digital banks face a new set of opportunities and challenges. With central banks in Europe, the USA, and LATAM beginning to reduce interest rates, the profitability model that digital banks thrived on is shifting. This blog will explore how digital banks in these regions have benefited from high interest rates and what the future holds as rates begin to fall.

In our next blog, we will explore the ranking of the digital banks with the highest level of deposits, so stay tuned!


Key Points Discussed in the Blog:

  • Adapting to Falling Interest Rates: Digital banks in Europe, the USA, and LATAM are shifting strategies to maintain profitability, focusing on product diversification and cost efficiency as interest margins tighten.

  • Regional Growth and Expansion: Banks are seizing opportunities in regions like the Middle East, Colombia, and Argentina through tailored services and cross-border expansion.

  • Leveraging Technology and Innovation: Digital banks, exemplified by Klarna, Revolut and Monzo, are using AI-driven solutions and new product offerings like stablecoins and investments to enhance competitiveness in a low-rate environment.


How Digital Banks Benefited from High Interest Rates


During the period of elevated interest rates, digital banks capitalized on the environment by:

  • Enhancing Profit Margins: Digital banks took advantage of the widening gap between the interest rates they offered on savings accounts and the higher rates they charged on loans, significantly boosting their profitability. This allowed them to maintain strong financial performance with lower overhead costs compared to traditional banks. Additionally, their ability to quickly adjust to market conditions and offer competitive rates attracted more customers, further increasing their profit margins during the high-interest-rate period.



  • Attracting Depositors: Digital banks capitalized on higher savings rates, offering more attractive returns than traditional banks, which drew in customers seeking better financial benefits. Their user-friendly platforms, combined with competitive rates, made them appealing to tech-savvy individuals who valued both convenience and profitability. This influx of depositors not only strengthened their customer base but also increased their liquidity, enabling them to fund more lending activities and expand their services.

  • Lending Growth: Digital banks capitalized on higher loan rates, boosting their revenues from lending products such as personal loans, mortgages, and business loans. While higher rates sometimes tempered demand, especially among risk-averse customers, digital banks offset this by offering more streamlined and accessible lending processes, often with faster approvals. Their ability to attract younger and underserved customers, who valued flexibility and transparency, helped them maintain steady loan growth despite the challenges posed by higher interest costs.

However, with interest rates now poised to fall, the digital banking sector must pivot and adapt.


Europe: Strategic Adaptations Amid Slowing Rate Cuts


In September 2024, the European Central Bank (ECB) cut rates to 3.5%, marking the second reduction this year. While interest rates are falling, economists believe they may not return to the ultra-low levels of 0.25% seen before. This new baseline of around 3% could still offer digital banks opportunities to capture decent margins. Banks like Starling Bank and Revolut stand out as strong players due to their focus on product diversification and innovation, allowing them to remain profitable in a lower-rate environment.


Examples of European Digital Banks Adapting:


  • Bunq is adapting to lower interest rates with strategies like Freedom of Choice, allowing users to control deposit investments, and MassInterest, offering a 3.36% bonus rate to reward savers. Additionally, Bunq's entry into the insurance market with worldwide travel coverage caters to its growing base of 12.5 million users and over 8 billion euros in deposits, diversifying its income streams and reducing reliance on interest margins. These innovations position Bunq for continued growth and resilience.

  • N26 has expanded into investment products, offering services like stock trading and portfolio management through its mobile app. This strategic move not only diversifies its revenue streams but also attracts a broader customer base, particularly those looking for easy access to financial markets. By reducing its reliance on traditional banking income from interest-based products, N26 can better cushion against fluctuations in interest rates. Additionally, offering investment services enhances customer engagement, positioning N26 as a more comprehensive financial platform that meets both banking and investment needs.



  • Revolut continues to offer a broad suite of services, including travel insurance, stock trading, and budgeting tools, which help diversify its revenue streams and reduce reliance on traditional banking margins. Additionally, Revolut is preparing to launch its own stablecoin, expanding its presence in the cryptocurrency market. This move into stablecoins further enhances Revolut's service offerings, catering to crypto enthusiasts and generating new income from crypto trading and transactions. Revolut is also pursuing cross-border expansion with plans to enter the Middle East by seeking an electronic money institution (EMI) licence from the Central Bank of the UAE. This expansion will enable Revolut to offer remittance services, tapping into a region with significant growth potential. By providing such diverse financial products and expanding globally, Revolut can better withstand interest rate fluctuations, offering value-added services that go beyond core banking.


With interest rates unlikely to fall significantly below 3%, digital banks in Europe still have opportunities to maintain profitability by focusing on more sophisticated savings and investment products. This rate environment also provides opportunities for innovation, such as integrating AI-driven wealth management solutions.


UK: A Focus on Innovation and Customer Engagement


In the UK, where digital banking adoption has surged, the Bank of England is expected to follow suit with interest rate cuts in 2024. The current rate environment has been favorable for digital banks like Monzo, Starling, and Revolut, which have all benefited from higher margins on loans and deposit products. However, with the Bank of England’s future cuts, digital banks will need to shift their strategies to maintain growth.

Monzo is positioning itself for a lower interest rate environment through product diversification. Key moves include the launch of a pension consolidation product with BlackRock, aimed at long-term savings, and expansions into sole trader loans, investments, and potentially mortgages. This broad product range enables Monzo to reduce reliance on interest-based income by generating fee-based revenue from various financial services. Additionally, by targeting younger customers with under-16 accounts, Monzo is cultivating future loyalty, which will be crucial in maintaining a solid customer base as interest margins shrink. This multi-faceted strategy ensures that Monzo can remain competitive and sustain growth even with tighter lending margins.

Starling Bank is diversifying its revenue streams. A key pillar of this strategy is its expansion into business banking, where it offers tailored services for SMEs, providing a more stable and long-term income source compared to consumer lending. This helps cushion the effects of reduced lending margins.

In addition, Starling’s Engine by Starling platform is expanding globally, offering Software-as-a-Service (SaaS) to other financial institutions, creating new fee-based revenue streams that are less dependent on interest rates. Recent partnerships in Australia and Romania highlight the bank's commitment to scaling this technology​

While the bank faces challenges from increased competition and tighter margins, its strategy of expanding customer acquisition through a new brand platform "The Bank Built for You" and its continued push for international growth position it to navigate the shifting interest rate environment effectively​.



LATAM: Interest Rates, Innovation and Regional Expansion


Colombia: A War on Interest Rates and Product Innovation

Colombia is currently experiencing an intense focus on interest rates as inflationary pressures ease, following the Central Bank’s reduction of the benchmark rate by 50 basis points to 10.75% in 2024. Analysts and the market expect rates to fall further, potentially closing the year at 8.5%. According to Ricardo Bonilla, the Minister of Finance, the Central Bank may lower rates by 75 basis points in each of the remaining three meetings of the year. This shift is creating a new environment for digital banks.


Lulo Bank, Colombia's first fully digital bank, has set itself apart by offering innovative financial products, including personalized lending options and enhanced user experiences through advanced technology. With interest rates on the decline, Lulo is well-positioned to capture market share by appealing to younger, tech-savvy consumers seeking agile banking solutions. Currently, competitors like Rappipay offer savings rates around 14%, making it essential for Nubank, Lulo, Ualá and others to remain competitive in this changing landscape.

Additionally, the central bank’s push to lower interest rates opens up opportunities for digital banks to expand their lending products while managing risks associated with economic volatility. For example, banks could introduce more accessible lines of credit for small businesses, a sector that remains underserved in Colombia.


Argentina: Opportunities in a Recovering Economy


Looking forward, Argentina’s economy is expected to improve by 2025, providing fertile ground for regional expansion in LATAM. As Argentina emerges from its economic crisis, digital banks could play a critical role in helping stabilize and support the financial sector by offering accessible credit, savings solutions, and innovative products. Digital banks like Ualá and Brubank are well-positioned to capitalize on this recovery, potentially expanding their customer base by catering to the underbanked population.


In terms of interest rates, Argentina’s central bank is expected to maintain high rates in the near term to combat inflation but may begin easing monetary policy as the economy stabilizes toward 2025. This presents both challenges and opportunities for digital banks. On the one hand, high rates make borrowing more expensive, limiting credit demand, but on the other, they attract deposits with attractive savings rates. As rates potentially decrease with economic recovery, digital banks will be able to offer more affordable credit options, stimulating growth in consumer spending and small business investments.


Additionally, with the expected rise in consumer spending and demand for more efficient financial services, these banks could introduce new products such as digital payments and remittance services, which are vital in a recovering economy. This expansion into Argentina would allow digital banks to benefit from increased consumer demand for accessible financial services as the economy recovers, while also fostering greater financial inclusion.


The Impact of Nubank’s Strategic Shift


A significant development in LATAM is Nubank’s decision to close its cryptocurrency offering. Nubank initially embraced cryptocurrency as part of its product diversification strategy, but recent regulatory concerns and shifting market conditions prompted the bank to pull back. This highlights the risks digital banks face when expanding into volatile sectors, but also underscores the need for strategic agility as they navigate a changing environment.

Despite this, Nubank remains one of the best-positioned digital banks in LATAM, thanks to its strong consumer base, broad product offering, and focus on innovation. As interest rates fall, Nubank will likely shift its focus to more stable revenue streams like lending and credit products, particularly for underserved markets.


USA: Navigating the Fed’s Rate Cut


In the USA, the Federal Reserve on Wednesday cut its benchmark interest rate by an unusually large half-point, marking a dramatic shift after more than two years of high rates aimed at taming inflation. While these high rates made borrowing expensive for American consumers, this reduction signals the beginning of a rate-cutting cycle, the first in over four years. Historically, Fed rate cuts have bolstered equities and housing markets, but for digital banks, the challenge lies in maintaining profitability as loan margins shrink.


SoFi and Ally Bank are well-positioned to navigate this shift due to their diverse product offerings. SoFi, for example, has expanded into student loan refinancing, investments, and other services, making it less dependent on interest rate-driven income. Similarly, Wealthfront is leveraging its investment and robo-advisor services to attract long-term customers who seek more than just traditional banking products.


Additionally, in the teen and kids market, GoHenry, has partnered with Google to allow children under 13 to make purchases using Tap to Pay through Fitbit Ace LTE smartwatches. As interest rates drop, banks and fintech companies may face tighter margins from traditional lending products, making it crucial to explore new revenue streams and expand customer bases. Targeting younger demographics not only promotes financial literacy but also helps digital banks like GoHenry build long-term relationships with future customers.

By integrating wearable technology into banking, GoHenry is positioning itself to grow user engagement from an early age. This strategy ensures that when these young users become financially independent, they are more likely to continue using GoHenry’s services. As interest rate-driven income shrinks, cultivating lifelong customer loyalty through innovative products like Tap to Pay offers digital banks a way to diversify their revenue streams while creating a new generation of financially savvy customers.


Although interest rates are unlikely to return to the ultra-low levels of the past, digital banks in the US still have room to maintain profitability by diversifying services, enhancing customer experience, and exploring new revenue streams through partnerships and financial technology.


Tech-Driven Innovation: Klarna’s Use of AI for Cost Reduction


One standout example of how digital banks can use technology to stay ahead in a lower interest rate environment is Klarna. The Swedish fintech giant has implemented AI-driven solutions to significantly reduce operational costs, allowing it to remain competitive even as margins tighten. By using AI to automate customer service, credit assessments, and fraud detection, Klarna is not only improving its cost structure but also enhancing customer experience, giving it a strategic edge in the highly competitive Buy-Now-Pay-Later (BNPL) space.


Digital banks across all regions could learn from Klarna’s approach by leveraging AI to improve efficiency, reduce costs, and personalize the customer journey, ensuring that they remain competitive as interest rates decline.


What to Expect as Interest Rates Stabilize at Lower Levels


While rates may not fall to the ultra-low levels seen in past years, the stabilization of lower interest rates presents digital banks with new opportunities:


  • Moderate Borrowing Costs: With borrowing costs significantly lower than recent highs, digital banks have the opportunity to expand lending to businesses and consumers who were previously priced out of the market. Lower rates can stimulate demand for personal loans, mortgages, and SME financing, allowing digital banks to capture new customers while maintaining profitability through streamlined operations and innovative underwriting processes.


    Banks with robust lending offerings, like SoFi and Starling Bank, are particularly well-positioned to take advantage of this. Additionally, SME-focused players such as OakNorth, Allica Bank, Kompasbank, and Aprila Bank are set to benefit from increased demand for business loans as small and medium-sized enterprises seek affordable financing options. These banks’ specialized lending products and focus on business customers enable them to capture market share while maintaining solid profitability in a lower-rate environment. A strong lending portfolio allows these banks to maximize opportunities and meet rising demand for credit.

  • Diversification into Fee-Based Services: As interest margins shrink, digital banks will increasingly rely on fee-based services to maintain profitability. Products like subscription models for premium services, investment platforms, insurance, and wealth management tools can provide stable income streams. Banks such as Revolut and Monzo have already diversified into areas like investments and travel insurance, which are less reliant on interest rates. This shift helps balance revenue streams and reduces dependency on lending income.

  • Customer Acquisition through Competitive Products: Digital banks that offer innovative, technology-driven solutions will continue to gain market share, particularly by targeting younger, tech-savvy users. Products like mobile wallets, budgeting tools, and financial literacy apps cater to a generation that values convenience and personalized banking experiences.

  • Cross-Border Expansion: The stabilization of lower interest rates can encourage digital banks to explore cross-border opportunities because it reduces the cost of capital, making it more affordable to fund expansion into new markets. With lower borrowing costs, digital banks can invest in entering regions with high growth potential, such as Argentina, where economic recovery is expected by 2025. As the economy improves, demand for accessible financial products, such as digital payments and lending services, will likely rise, creating an attractive market for new entrants


    Beyond Argentina, countries like Brazil and Mexico also offer fertile ground for digital banks, as their growing fintech ecosystems and large underbanked populations create opportunities for new entrants. In India, the rapid growth of digital banking driven by government initiatives and mobile adoption further underscores the potential for cross-border expansion in emerging markets.


    Recently Revolut has announced plans to enter the Middle East, submitting licence applications to the Central Bank of the UAE. Revolut is seeking an electronic money institution (EMI) licence in the UAE to offer its remittance services. This move highlights how digital banks can take advantage of favorable financial conditions to tap into new regions with significant growth potential and demand for innovative financial services.


A New Phase of Strategic Adaptation


As interest rates come down across Europe, the USA, and LATAM, digital banks must adapt to a new financial reality. Those institutions that can diversify their revenue streams, leverage technology to reduce costs, and expand into underserved markets will thrive. Banks with robust lending offerings and strong deposit bases, such as SoFi, Starling Bank, OakNorth, and Allica Bank, are particularly well-positioned to capitalize on moderate borrowing costs by expanding SME lending and consumer loan portfolios. A high level of deposits provides these banks with more liquidity, allowing them to offer loans more competitively and sustain lending growth even as interest margins shrink.


Equally important is their ability to maintain and grow their deposit bases. As interest rates drop, keeping depositors engaged with attractive savings options and user-friendly banking experiences becomes crucial. Banks that successfully retain and grow their deposits will be better equipped to fuel lending and maintain liquidity without relying on costly external funding.


At the same time, the strategic closure of high-risk ventures, like Nubank’s cryptocurrency offering, highlights the importance of agility and focus in this rapidly evolving sector. By shifting away from volatile products and emphasizing core financial services, these banks are better equipped to manage risk.


In addition, expected interest-rate cuts could boost startup investment and help reopen the IPO market, creating opportunities for digital banks to access new capital. This could accelerate growth and enable more fintech players to go public, driving innovation and competition in the sector.


By focusing on innovation, operational efficiency, customer-centric solutions, and deposit retention, digital banks are well-positioned to navigate this new environment and continue their growth in the years ahead. The combination of strong deposits, competitive lending products, and the ability to adapt quickly to market changes will be key to thriving in a lower-rate financial landscape.
