UK Debt-to-Income Ratio Hits Record Low Despite Rising Credit Balances: TransUnion Report

UK consumer credit balances are surging, with credit card debt rising 9.1% year-over-year, yet a concurrent rise in median incomes has pushed debt-to-income ratios to their lowest levels since 2019. For fintech professionals, this signals a market defined by increased lender risk appetite and deeper penetration among existing customers rather than a broadening of the overall borrower base.

What was announced

TransUnion’s Q2 2026 UK Credit Industry Insights Report highlights a complex landscape where absolute debt is growing but remains manageable relative to earnings. Unsecured loan balances grew by 7.9% year-over-year (YoY), while credit card debt outpaced the Q2 2026 annual price inflation rate of 2.8% significantly, rising by 9.1%. Despite these headline figures, the debt-to-income ratio fell to 3.79, down from 3.85 in Q2 2025 and well below the 5.78 recorded in Q2 2019, prior to the pandemic.

The data reveals a shift in lender behavior, with risk appetite returning to pre-pandemic norms. Average credit scores for newly opened accounts have dropped by 32 points for credit cards and 28 points for unsecured loans since the conservative peak of Q2 2023. This increased risk-taking has been accompanied by a rise in serious delinquency; the proportion of credit-active consumers with at least one account 90 or more days past due rose by 30 basis points YoY to 3.50%. Unsecured loans saw the sharpest deterioration, with delinquency rates climbing 68 basis points to 4.39%.

Crucially, the report notes that the number of credit participants is stagnating. The proportion of adults holding credit rose only slightly to 70.0% in Q2 2026, remaining below the 73.5% seen in 2019. Growth is instead being driven by "interconnectedness," where existing borrowers hold more concurrent accounts with multiple lenders, rather than a comparable expansion in the number of people using credit.

"The increase in consumer unsecured delinquency rates should not be overlooked, particularly within unsecured loans, where the movement has become more pronounced. However, overall consumer delinquency rates are still sitting well below pre-pandemic norms, debt remains historically low relative to income and performance has improved across mortgages and motor finance. The evidence points to segments of emerging pressure among an otherwise stable and resilient consumer base."

What this means

The UK credit market is entering a phase of "intensive" rather than "extensive" growth. The fact that fewer people are using credit than in 2019, while those who do are holding more products, suggests a saturation point among the prime borrower demographic. This puts immense pressure on traditional lenders and fintechs to differentiate through service and responsible limit management rather than just availability. The rising delinquency in unsecured loans, coupled with lower entry scores, indicates that the industry's drive for volume is beginning to test the limits of consumer resilience. The real challenge for the sector is no longer just managing debt-to-income ratios, but navigating the systemic risk of highly interconnected borrowers who hold concurrent relationships with multiple lenders.
