Interest Income Drives Neobank Survival

Higher rates split the neobank market into survivors and casualties, because they rewarded banks with real balances and lending engines while cutting off easy venture funding for everyone else. Once money stopped being free, a neobank could no longer live on a branded debit card and thin interchange margins. The winners turned deposits into interest income and profits, while weaker and more niche players hit layoffs, shutdowns, or failed fundraises.

• Monzo shows what survival looked like in practice. In its March 2024 fiscal year, revenue more than doubled and net interest income rose 167%, enough to push the business to its first full year of profit. That is a very different model from relying mainly on card swipe fees.

• The pressure on weaker neobanks was immediate. Aspiration cut more than half its staff in April 2023 as its SPAC path slipped. Daylight said in May 2023 that it was shutting down. GloriFi shut down in November 2022, less than a year after launch.

• This was especially brutal for identity or mission led banks, because a strong brand can win signups but it does not create balance sheet earnings. When customer acquisition got expensive and investors demanded clearer unit economics, narrow positioning stopped being enough to finance losses.

The next phase belongs to neobanks that look more like real banks and less like lightweight card apps. That means more deposits, more lending, more subscriptions, and broader product bundles that raise revenue per customer. As rates normalize, the durable players will be the ones that used this period to build recurring earnings beyond interchange.
