Brazil's consumer debt trap

Brazil's personal loan default rate reached 7.8% in July — the highest level since 2009. Corporate defaults climbed to 4.2%. Nearly half the adult population, some 80 million people, carry delinquent debts. The numbers describe a household balance sheet stretched to its limit. The more interesting question for investors is what is being done about it, and who profits from the answer.

The answer, for the moment, is more credit.

President Luiz Inácio Lula da Silva's administration has responded to a slowing economy and an October election by expanding access to consumer finance. The headline programme is payroll-deductible lending, previously restricted by employer-lender agreements. The government opened it to all formal private-sector workers, including domestic and rural employees. The result has been a boom: outstanding payroll loans rose 48% in the first half of 2026 to 113 billion reais ($22 billion), tripling the pre-reform level. Defaults within that programme alone hit 8.6% in June. The central bank's statistics chief acknowledged most of the growth represents new borrowing rather than refinancing existing debt.

A broader driver-financing scheme was launched in May with 30 billion reais in funding. It gained little traction. The government then broadened eligibility and extended repayment from 72 to 84 months. A debt-renegotiation programme has restructured more than 22 billion reais. A measure cleared in late June allows lenders to seize workers' severance-fund balances to cover overdue loans, strengthening bank guarantees rather than reducing household obligations.

The central bank finds itself on the opposite side of the ledger. It began cutting its benchmark Selic rate in March, bringing it from 15% to 14% by August — a four-step easing cycle. Yet the governor, Gabriel Galípolo, warned that stimulating credit while household debt sits at 50% of disposable income "exacerbates indebtedness and complicates the fight against inflation." The bank flagged upside risks to inflation from government measures that stimulate consumption. It is one of the highest real interest-rate environments among major economies, and credit costs reflect it: the average personal loan carries a 60% annual rate; revolving credit card debt, 436%.

The conflict between monetary policy and fiscal stimulus is not new. What is notable is its distributional consequence for investors who hold Brazilian financial stocks.

Brazil's four largest banks — Itaú Unibanco, Bradesco, Banco do Brasil, and Santander Brasil — set aside $9.1 billion for bad loans in the second quarter, up from $7.7 billion the quarter before. Provisions are growing faster than the loan book. The response has been a coordinated retreat from riskier lending. Itaú's chief executive warned that household income commitment levels were "excessively high" and tilted the portfolio toward secured credit. Bradesco's chief reported "far more selective" underwriting with reduced appetite for lower-income clients. Santander cut exposure to borrowers earning under 4,000 reais per month — roughly 2.5 times the minimum wage — and now requires collateral above that threshold. Banco do Brasil faces agricultural loan defaults that doubled year-on-year to 6.27%.

Yet all four remained profitable in the second quarter. Itaú, the largest, earned 12.4 billion reais — its 11th consecutive quarterly profit increase. The high-rate environment is a double-edged sword: it drives up default rates, but it also keeps net interest margins wide. The banks are earning more per outstanding loan even as they lend to fewer people and to safer borrowers. Itaú's cost of credit sat at roughly 2.7% of its loan book. Bradesco's profit grew 16%. The trade-off is a slower credit book, but a more defensible one.

Nubank, the publicly traded digital lender listed on the New York Stock Exchange under the ticker NU, occupies a different position. Its business is concentrated in unsecured consumer lending — precisely the segment the traditional banks are abandoning. Loans over 90 days past due rose to 6.9% in the second quarter, up from 6.5% the quarter before and the same period last year. The company still reported a record $1.06 billion in quarterly profit, a 49% year-over-year increase, with revenue up 39% to $5.88 billion and a return on equity of 33%. Cost of credit fell 9% quarter-on-quarter to $1.7 billion. Management stated there is no "broad-based deterioration" among consumers.

The arithmetic is legible. Nubank's cost of credit of $1.7 billion against net income of roughly $1.1 billion means provision expenses consume about 60% of reported profit. That is a manageable ratio so long as delinquency stabilises. The question is whether it will. The central bank's own statistics chief said there was no statistical evidence that delinquency rates had peaked. Nubank's sequential improvement in cost of credit is a seasonal pattern — early delinquencies typically ease in the second quarter — rather than a structural resolution.

For a U.S. investor, the implication turns on what each business model is buying.

Itaú Unibanco, accessible through its ADR ITUB on the New York Stock Exchange, offers exposure to a bank that is actively shrinking its risk. Provisions rose sharply, but the bank earned more. Its 11-quarter profit streak suggests management has navigated the credit cycle with discipline. The risk is that a retreat from consumer lending caps growth. Brazil's economy is projected to grow around 1.5% to 1.6% in 2026 and 2027, well below its potential rate. A bank that lends less in a slow economy earns stably, but not spectacularly. Itaú trades at a valuation that reflects its franchise quality: AInvest's aggregate signal rates its fundamentals strongly, at 7.72 out of 10.

Nubank trades at a premium that reflects its growth. AInvest's composite rating of 2.24 and fundamental score of 1.52 out of 10 signal that its valuation is not supported by traditional fundamentals — the stock is priced for continued expansion. The structural question is whether expansion can continue while defaults rise. The government's credit stimulus programme may temporarily sustain loan growth by pushing more borrowers into the system. It may also accelerate the deterioration that follows, as more households reach their borrowing ceiling. Nubank's business depends on the former without the latter. That is a wager, not a certainty.

There is a third variable: the real. The currency has hovered around 5.15 reais to the dollar in recent weeks. A weaker real hurts the dollar-denominated earnings of both ITUB and NU. A stronger real — which could follow sustained Selic cuts if inflation cooperates — would boost reported earnings. The central bank's easing cycle depends on the government's fiscal discipline. The government has not demonstrated a willingness to restrain the very stimulus that complicates the bank's mandate. The currency will price that tension.

The political dimension cannot be ignored. October's election sits ahead. The government's strategy — expand credit, stimulate consumption, restructure debt — is the sort of programme that looks like action and delivers relief to a visible constituency. Its cost is diffuse: higher inflation, a delayed rate-cutting cycle, and a banking system managing a structural deterioration in household creditworthiness. The central bank must bear the responsibility for the outcome it did not engineer. That is the institutional dilemma, repeated in many countries: fiscal stimulus that looks helpful today becomes the constraint on monetary policy tomorrow.

Investors who hold Brazilian financial stocks are not betting on the quality of Brazilian consumers. They are betting on how banks price and manage the risk of those consumers, and on which government wins the October election. The traditional banks have answered by tightening and earning more per loan. Nubank has answered by growing faster and absorbing the cost. Both strategies can work for a while. Both assume the deterioration stops before the balance sheet breaks. The evidence so far does not confirm either assumption.
