Financial generation companies have been to start with the most important losers of rate of interest hikes via international central banks in 2022, which ended in tumbling valuations.
With time even though, this transformation within the rate of interest setting continuously boosted income for fintechs. This is as a result of upper charges spice up what is known as internet hobby source of revenue — or the variation between the charges charged for loans and the hobby paid out to savers.
In 2024, a number of fintechs — together with Robinhood, Revolut and Monzo — noticed a spice up to their backside strains because of this. Robinhood reported $1.4 billion in annual benefit, boosted via a 19% bounce in internet hobby source of revenue year-over-year, to $1.1 billion.
Revolut additionally noticed a 58% bounce in internet hobby source of revenue final yr, which helped elevate income to £1.1 billion ($1.45 billion). Monzo, in the meantime, reported its first annual benefit within the yr finishing March 31, 2024, buoyed via a 167% building up in internet hobby source of revenue.
Now, fintechs — and particularly virtual banks — face a key check as a extensive decline in rates of interest raises doubts concerning the sustainability of depending in this heightened source of revenue over the long run.
“An environment of falling interest rates may pose challenges for some fintech players with business models anchored to net interest income,” Lindsey Naylor, spouse and head of U.Okay. monetary products and services at Bain & Company, instructed CNBC by way of electronic mail.
Falling benchmark rates of interest may well be “a test of the resilience of fintech firms’ business models,” Naylor added.
“Lower rates may expose vulnerabilities in some fintechs — but they may also highlight the adaptability and durability of others with broader income strategies.”
It’s unclear how important an affect falling rates of interest may have at the sector general. In the primary quarter of 2025, Robinhood reported $290 million of internet hobby revenues, up 14% year-over-year.
However, within the U.Okay., effects from bills infrastructure startup ClearBank hinted on the affect of decrease charges. ClearBank swung to a pre-tax lack of £4.4 million final yr at the again of a shift from hobby source of revenue towards fee-based source of revenue, in addition to expenditure associated with its growth within the European Union.
“Our interest income will always be an important part of our income, but our strategic focus is on growing the fee income line,” Mark Fairless, CEO of ClearBank, instructed CNBC in an interview final month. “We factor in the declining rates in our planning and so we’re expecting those rates to come down.”
Income diversification
It comes as some fintechs take steps to take a look at to diversify their income streams and cut back their reliance on source of revenue from card charges and hobby.
For instance, Revolut provides crypto and proportion buying and selling on best of its fee and foreign currency products and services, and lately introduced plans so as to add cell plans to its app within the U.Okay. and Germany.
Naylor stated that “those with a more diversified mix of revenue streams or strong monetization of their customer base through non-interest services” are “better positioned to weather changes in the economy, including a lower rates environment.”
Dutch neobank Bunq, which objectives principally “digital nomads” preferring to not paintings from one location, is not fazed via the chance of rates of interest coming down. Bunq noticed a 65% bounce in annual benefit in 2024.

“We’ve always had a healthy, diverse income,” Ali Niknam, Bunq’s CEO, instructed CNBC final month. Bunq makes cash from subscriptions in addition to card-based charges and hobby.
He added that issues are “different in continental Europe to the U.K.” given the area “had negative interest rates for long” — so, in impact, the company needed to pay for deposits.
“Neobanks with a well-developed and diversified top line are structurally better positioned to manage the transition to a lower-rate environment,” Barun Singh, fintech analysis analyst at U.Okay. funding financial institution Peel Hunt, instructed CNBC.
“Those that remain heavily reliant on interest earned from customer deposits — without sufficient traction in alternative revenue streams — will face a more meaningful reset in income expectations.”
