Revolut's rate-driven margin squeeze
Revolut
Revolut’s recent profit jump says more about the rate cycle than about a permanently higher margin bank. When central bank rates are high, customer balances parked in current accounts throw off meaningful interest income with little extra sales effort. In 2024, interest income reached £790M, versus £500M in 2023, helping lift group revenue to £3.1B, or $4.0B. If rates fall back toward zero, that easy spread shrinks fast, and the mix shifts back toward card swipe fees and foreign exchange, which are higher volume but structurally thinner margin businesses.

Interchange is a small cut of card spend, usually around 0.7% to 1.5% of payment volume for neobanks after network economics. That works when users spend heavily, but it takes a lot more transactions to replace lost interest income than to earn it from deposits sitting on balance sheet.

This is a sector pattern, not just a Revolut issue. Monzo got 51% of 2023 revenue from interest, while N26’s interest revenue reached about half of total revenue in 2024 after deposits passed $11.1B. Higher rates made several European neobanks look suddenly much more profitable.

Revolut has been trying to reduce that exposure by adding businesses with better economics than interchange alone, including subscriptions, lending, wealth, and business banking. Wealth revenue reached $647M in 2024, and Revolut Business exceeded £460M of revenue, which matters because those lines are less directly tied to base rates than deposit spread income.
The next phase is about turning Revolut from a rate assisted neobank into a genuinely diversified financial app. If deposits become less lucrative, the winners will be the players that can get the same customer to borrow, invest, subscribe, and run a business through the same app, so revenue keeps compounding even when cash yields stop doing the work.
