What happens when you cap consumer credit interest rates at 10%? In the UK, we debated this for years. Then in 2015, the FCA introduced price caps on high-cost short-term credit. Wonga collapsed in 2018. The payday loan market shrank by half then disappeared completely. The industry fundamentally changed. Switzerland went further. In 2016 they capped all consumer credit at the 3-month SARON (Swiss Averade Rate Overnight)+10%, and +12% for Overdrafts and Credit Cards. I've been researching Swiss consumer finance recently and the findings challenge some assumptions we hold in UK financial services...
The Swiss Model
Since the most recent rate review in January 2026, Swiss personal loans are now capped at 10% APR. Credit cards at 12% APR. For context:
- UK credit card rates average around 21.5%
- UK personal loan rates average 8.85%
- UK high-cost short-term credit is capped at 0.8% per day with a 100% total cost cap
The Swiss go further than rate caps though. Before any funds are released, there's a mandatory 14-day cooling-off period. Every application is checked against ZEK, Switzerland's single mandatory credit bureau. And lenders must prove the borrower can repay within 36 months from income alone. That last point is worth exploring.
The 36-Month Affordability Test
This is where it gets interesting. Under Swiss law (the Konsumkreditgesetz or KKG), a borrower is only deemed creditworthy if they can repay the entire loan within 36 months from disposable income. Not "can they make the monthly payment". Can they clear the debt in three years.
Worked example
A borrower wants CHF 30,000 at 10% APR over 36 months. Monthly repayment: CHF 962. To qualify, their disposable income (after rent, taxes, existing debts, dependants) must be at least CHF 962 per month. If it falls short, they don't get the loan. Simple. Now compare that to the UK. A borrower wants £30,000 at 10% APR over 72 months. Monthly repayment: around £550. UK affordability checks under FCA rules ask: can they afford £550 a month based on income and expenditure? If yes, approved. The Swiss would calculate it differently. They work out the total repayment over 72 months (roughly £39,500 including interest), then check if the borrower could clear that amount in 36 months. That needs disposable income of around £1,100 per month. Same loan. Same borrower. Very different outcomes. (Source: Moneyland.ch, Swiss Consumer Credit Act Article 28)
The Subprime Question
When you cap rates at 10% across all consumer credit, high-cost lending becomes mathematically impossible. The risk premium simply cannot be priced in. The UK took a different approach. The FCA's 2015 price cap targeted high-cost short-term credit specifically:
- 0.8% per day maximum on interest and fees
- £15 cap on default charges
- 100% total cost cap (borrowers never repay more than double what they borrowed)
This shrank the UK payday market from roughly 10 million loans per year in 2013 to 5.4 million by 2018. Several major lenders exited, including Wonga, QuickQuid, and Dollar Financial and then the market collapsed completely. Switzerland's broader cap produces different outcomes: (Sources: Statista UK Consumer Credit Write-offs; Swiss Info) Swiss consumers face higher rejection rates, but those who do borrow are less likely to default. The question is whether that trade-off is right for a given market.
Swiss Consumer Attitudes
Perhaps the most interesting finding is cultural. Research from the Swiss Journal of Economics and Statistics shows debt carries genuine social stigma in Switzerland. Particularly in German-speaking regions. Over-indebtedness is described as "tabooed, socially undesired, and highly stigmatised." Only 1.5 million Swiss residents out of 8.8 million are even registered with ZEK. Most people simply don't engage with consumer credit at all. They save for purchases, use debit cards, and treat borrowing as a last resort. Compare that to the UK where credit is normalised, marketed, and actively encouraged. We celebrate points, cashback, and rewards. We spread costs as a lifestyle choice. Neither approach is inherently right or wrong. But they produce very different market dynamics.

Where the UK Leads: Open Banking and Digital Lending
The UK is dramatically ahead on fintech infrastructure.
Open banking adoption
- 16+ million UK users as of late 2025 (up from 8 million in late 2023)
- 70% year-on-year growth in open banking payments between 2024 and 2025
- 351 million payments processed via open banking in 2025
This infrastructure enables real-time affordability checks, transaction-based underwriting, and instant lending decisions that Swiss incumbents cannot match.
Market projections
- UK fintech lending market: £14.28 billion in 2024, projected to reach £43.4 billion by 2033 (CAGR 13.15%)
- UK fintechs attracted £7.97 billion in investment in 2024, nearly half of all fintech funding across EMEA
Switzerland is not in the same conversation on fintech scale. (Sources: Open Banking UK; IMARC Group)
Where Switzerland Lags: The Digital Maturity Gap
This is where it gets interesting from a transformation perspective. According to Deloitte's 2024 Digital Banking Maturity Study, Swiss banks achieved an average digital maturity score of only 39 points out of 100. That's below the global average of 41. None qualified as "Digital Champions." The numbers tell a mixed story:
- 73% of Swiss residents use online banking (above the EU average of 55%)
- But mobile banking adoption sits at just 43% overall
- Three institutions control over 90% of the consumer finance market
- Legacy core banking systems remain widespread
Swiss banks increasingly recognise that innovation comes through partnership rather than internal development. But the gap between consumer expectations and institutional capabilities is widening. Younger Swiss consumers have used Revolut and N26. They expect digital-first experiences. The incumbents know this. They're just struggling to respond.

The Technology Opportunity
If you're a UK fintech or transformation specialist looking at Switzerland, the opportunity is clear: operational excellence within a strict regulatory framework. The regulation isn't changing. The 10% cap, the 14-day wait, the ZEK check, the 36-month affordability test. These are fixed. But nothing prevents:
Process automation
- Manual ZEK checks could be API-integrated and instant
- Paper-based application journeys could be mobile-first
- The 14-day cooling-off period could be managed with digital education and document preparation
Embedded finance
- UK retailers have offered sophisticated point-of-sale finance for years through broker platforms and waterfall decisioning
- Swiss embedded finance is nascent by comparison
- IKEA, Lidl, furniture retailers, solar installers are all exploring POS finance but the technology infrastructure lags
Data and decisioning
- Open banking equivalents are emerging in Switzerland but adoption is years behind
- Transaction-based underwriting is rare
- There's room for scoring innovation within KKG constraints
Core banking modernisation
- The digital maturity gap (39 vs 41 global average) suggests significant infrastructure investment ahead
- Several Swiss banks have announced digital transformation programmes
- Instant payments only launched in Switzerland in November 2023
The Swiss market doesn't need UK-style product innovation. It needs UK-style operational execution.
What Could the UK Actually Learn?
I'm not advocating for Swiss-style rate caps across all UK consumer credit. The markets are too different. But there are lessons worth considering:
- The 36-month income test Asking "can they repay in full from income within three years?" rather than "can they service the monthly payment?" would fundamentally change affordability assessments. The FCA has moved in this direction under Consumer Duty, but Switzerland shows how far the principle can be taken.
- Single bureau systems The UK's three-bureau model (Experian, Equifax, TransUnion) creates inconsistencies and arbitrage opportunities. Switzerland's single mandatory check through ZEK provides cleaner data and fewer loopholes. Worth considering as the UK debates credit information reform.
- Mandatory cooling-off periods The 14-day wait before funds release sounds archaic. But it forces reflection. How many UK borrowers would still take that loan if they had to wait two weeks? The FCA's focus on "sludge practices" and customer friction is related territory.
- BNPL regulation urgency Both countries have regulatory gaps for short-term credit. Switzerland exempts loans under three months from the KKG entirely. The UK has delayed BNPL regulation repeatedly. Someone will get hurt in both markets if this isn't addressed.
The Bigger Picture
The UK and Switzerland have made different choices about the same fundamental tension: access versus protection. The UK prioritises access. More people can borrow. More innovation happens. More products exist. But more people also end up in debt advice. Switzerland prioritises protection. Fewer people borrow. Less innovation occurs. But those who do borrow are more likely to repay. Neither system is perfect. The combination of UK fintech capability with Swiss affordability discipline would be genuinely powerful. Perhaps that's where both markets need to go.
