Itaú Unibanco (ITUB4) Q3 2026 earnings review
Itaú Unibanco expands loans fast, but lending spreads narrow
Itaú Unibanco, Brazil's largest private-sector bank, is growing its loan book fast in safer products while its lending spreads narrow. Loans rose 11% from a year ago excluding the sold Colombian retail unit, but net interest earned from clients grew 7% because growth came from lower-yielding mortgages and payroll loans. Chief executive Milton Maluhy Filho kept every full-year operational target unchanged and lowered the expected tax rate, lifting recurring profit to R$12.6 billion.
| Loan portfolio growth (excluding Colombia sale) | +10.9% +10.2% headline to R$1,544B |
|---|---|
| Financial margin with clients (excluding Colombia sale) | +6.9% +6.6% headline to R$33.3B |
| Recurring profit, excluding one-offs | R$12.6B +6.7% from a year ago ex-Colombia |
| Full-year tax rate outlook | Cut to 28–29% prior 29.5–32.5%; all other lines held |
⚖️ Verdict: ⚪ Neutral
The story is unchanged because lower overhead costs, strong trading gains and a lower tax bill offset flat service fees and tighter lending spreads. Core capital rose to 12.7% of risk-weighted assets, building a buffer for year-end payouts. Two cautions stand out: investment banking fees dropped by a quarter on slower bond issuance, and reserve coverage for problem corporate loans fell below 50%.
The question now is whether fast growth in secured loans can lift client interest income off the bottom of the full-year plan without higher credit costs. Either fourth-quarter client interest margin accelerates toward the 12% pace implied by the middle of the outlook, or it lands near the 5% floor while corporate loan reserves need rebuilding. Fourth-quarter results and the 2027 outlook in February will settle both.
🐂 Bull Case
Tight Cost Control Drove Better Brazil Efficiency
Itaú is keeping a lid on overhead even as it invests in technology and absorbs annual union pay raises. Non-interest expenses — salaries, branch costs and administrative bills — rose 1.7% from a year ago to R$17.1 billion, and dropped by 1.3 percentage points as a share of managerial operating revenue, to 34.8% by our math.
- Brazil efficiency ratio (costs as a share of revenue): 35.7%, improved by 1.4 percentage points from a year ago
- Consolidated efficiency ratio: 37.5%, improved by 1.3 percentage points from a year ago
- Nine-month non-interest expenses: up 3.1%, near the middle of the 1.5% to 5.5% full-year plan
Quarterly expenses rose 2.4% from the second quarter because the annual union agreement raised bank wages by 4.6% starting in September. Personnel and technology expenses in Brazil each stayed flat compared with a year ago, showing that earlier branch closures and headcount reductions are paying for software upgrades.
What to watch: fourth-quarter non-interest expenses, which will carry a full three months of the September wage hike. Staying near the 3.5% middle of the full-year outlook would confirm that digital savings offset union pay inflation.
Capital Rebuilt Ahead of Year-End Payouts
The Brazilian lender is building capital faster than its loan book is consuming it. Common Equity Tier 1 (CET1) — a bank's core loss-absorbing capital measured against risk-weighted assets — rose 0.4 percentage points from June to 12.7%, sitting well above the bank's 11.5% internal benchmark.
Quarterly earnings added 0.8 percentage points to the ratio, while loan and risk-weighted asset growth used 0.4 points and regular dividends took 0.1 points. Tangible equity (net worth excluding goodwill, intangibles and net deferred tax credits) climbed 6.7% in the quarter to R$138.7 billion. That surplus gives chief financial officer Gabriel Amado de Moura room for extra year-end payouts.
What to watch: the extraordinary dividend or buyback announcement with fourth-quarter results. A payout that brings CET1 back toward 12.0% would return several billion reais of excess capital to shareholders.
Trading Gains and Tax Cut Lifted Profit
Two non-lending lines carried third-quarter profit growth when client fees stood still. Financial margin with the market — profit from treasury trading and asset-liability management — rose 46.9% from a year ago to R$1.33 billion, as gains in Brazil jumped to R$1.7 billion and the cost of hedging foreign capital shrank to R$0.6 billion.
At the same time, Itaú lowered its full-year effective tax rate outlook from 29.5%–32.5% to 28.0%–29.0%, "reflecting the change in the Long-Term Interest Rate (TJLP) trajectory", which raises the tax deduction on interest on own capital payouts. Nine-month market margin of R$3.08 billion already sits inside the R$2.5–5.5 billion full-year plan.
What to watch: fourth-quarter financial margin with the market against the R$924 million needed by our math to reach the R$4.0 billion middle of the full-year outlook. A reading near that level would show treasury gains are holding up despite high Brazilian interest rates.
🐻 Bear Case
Loan Growth Outpaces Client Interest Income
Itaú's loan book is expanding fast because the bank is leaning into safer, lower-yielding loans, which also explains why interest income lags behind. Excluding the Colombian retail portfolio sold in July, total loans grew 10.9% from a year ago to R$1,544.4 billion (up 10.2% on a headline basis), while financial margin with clients — net interest earned on loans and deposits — rose 6.9% (up 6.6% headline).
- Private-sector payroll loans: up 93.7% from a year ago
- Mortgages: up 15.8% to R$158.8 billion, larger than the R$153.4 billion credit card book
- Government-sponsored small business loans: up 32.4% from a year ago
- Consolidated annualized average margin with clients: 9.0%, down 0.2 percentage points from a year ago
The company said client interest income was held back by "growth in secured portfolios, including mortgages, payroll loans and Government Program sponsored facilities, as well as by asset spread compression". Nine-month client interest margin is up 5.4%, sitting near the bottom of the 5.0% to 9.0% full-year plan.
What to watch: fourth-quarter financial margin with clients, which by our math must grow 3.8% from a year ago to meet the 5.0% outlook floor, or 11.7% to reach the middle of the range. A reading near the floor would show that safer loan mix permanently caps interest margin growth.
Corporate Provision Buffers Fell Below Half
Chief executive Milton Maluhy Filho highlighted "the quality of our portfolio" as headline 90-day delinquency held near 2.0%, and over-15-day corporate delinquency sat at 2.9% against 5.8% for the rest of the Brazilian market. Beneath those headline ratios, the bank is using up its corporate loan-loss reserves and selling bad loans to keep delinquency flat.
- Stage 3 coverage for companies (reserves against problem corporate loans): 49.5%, down from 52.9% in June and 57.8% a year ago
- Brazil small and medium business 90-day delinquency: 2.1%, up from 2.0% in June and 1.7% a year ago
- Sold overdue loans in Q3: R$251 million in total (R$140 million in small businesses, trimming that ratio by 0.05 percentage points)
- Renegotiated and restructured loan portfolio: R$37.0 billion, up from R$36.3 billion in June
Cost of credit — the quarterly charge for expected loan losses — rose 10.2% from a year ago to R$10.42 billion, outpacing the 5.5% rise in operating revenue. Because corporate Stage 3 coverage has dropped 8.3 percentage points in a year, new corporate defaults will require fresh income-statement charges rather than drawing on existing buffers.
What to watch: Brazil small business 90-day delinquency and companies' Stage 3 coverage in the fourth quarter. A rise in small business delinquency above 2.1% or another drop in corporate coverage would mean credit costs must rise in 2027.
Fee Income Stalled as Debt Issuance Slowed
After cutting its full-year fee and insurance growth outlook from 5.0%–9.0% down to 2.0%–5.0% last quarter, Itaú saw service revenues flatten out in the third quarter. Combined commissions, fees and insurance results edged up 0.2% from a year ago to R$14.1 billion (up 0.5% excluding the sold Colombian retail unit).
Asset management fees grew 17.8% from a year ago to R$2.2 billion and card issuance fees rose 5.8% to R$3.5 billion. However, investment banking and brokerage advisory fees dropped 26.6% to R$0.9 billion "mainly due to lower fixed-income securities issuance", while current account fees for individuals fell 16.9% to R$0.5 billion and payments and collections slipped 5.8% to R$1.9 billion.
What to watch: fourth-quarter commissions, fees and insurance growth, which by our math needs to reach 5.1% from a year ago to hit the 3.5% middle of the full-year outlook. Weak capital markets activity in the fourth quarter would push full-year fee growth toward the 2.0% bottom of the plan.

NeoSpace Buyout and SuperApp AI Rollout
On October 23, Itaú agreed to acquire NeoSpace, a Brazilian startup building foundational artificial intelligence models, for R$2.93 billion paid over five years. During the quarter the bank also launched ia.i, a conversational assistant inside its mobile app, launched the Itaú Pay digital checkout tool, and integrated reward points into Brazil's Pix instant payment system, "enabling clients to use their reward program points directly for PIX transactions".
💲 Other KPIs
Retail banking carried profit growth while corporate and investment banking slipped. Retail recurring net income rose 10.6% from a year ago to R$5.22 billion on higher loan volumes and lower efficiency costs. Wholesale recurring net income fell 4.6% from a year ago to R$5.68 billion as investment banking fees dropped and corporate credit costs rose 14.9%.
Customer deposits grew 4.3% over the first nine months of 2026 from R$1,114.5 billion at year-end, led by an 8.2% rise in time deposits to R$854.1 billion. Because funding grew faster than the net loan book after the Colombia sale, the ratio of loans to funding dropped 1.7 percentage points in the quarter to 78.6%.
Profit per diluted share under international accounting rules rose 8.9% from a year ago, outpacing the 6.2% rise in recurring managerial net income. Weighted average diluted shares edged down 0.3% from a year ago to 11.15 billion as the bank bought back R$1.76 billion of preferred stock over the first nine months.
🔮 Guidance
Cut. The bank lowered its full-year tax rate plan by 2.5 percentage points at the middle of the range, to 28.5%. Management said the move reflects a higher Long-Term Interest Rate (TJLP), which increases the tax shield from interest on own capital distributions. Through nine months, the managerial effective tax rate is already 28.4% by our math.
Unchanged. The plan still calls for 7.0% growth at the middle of the range. With nine-month client interest margin up 5.4%, by our math fourth-quarter growth must accelerate to 11.7% from a year ago to hit the middle of the range, or reach 3.8% to stay above the 5.0% floor.
Unchanged. Total loans are up 10.2% from September last year (10.9% excluding the Colombia sale), sitting above the top of the full-year range. Because fourth-quarter 2025 had a high seasonal base of R$1,490.8 billion, by our math the portfolio still needs to add R$58.2 billion in the fourth quarter to hit the 7.5% middle of the plan.
Unchanged. Nine-month loan-loss charges reached R$30.51 billion, up 7.4% from a year ago. By our math, that leaves R$10.49 billion for the fourth quarter to land at the R$41.0 billion middle of the range, virtually flat against the R$10.42 billion recorded in the third quarter.
Unchanged. After cutting this target from 5.0%–9.0% last quarter, management kept the 2.0%–5.0% range. Nine-month fee and insurance revenue is up 3.0%. By our math, fourth-quarter growth must pick up from 0.2% in the third quarter to 5.1% to reach the 3.5% middle of the range.
Unchanged. Nine-month expenses are up 3.1%, below the 3.5% middle of the range. By our math, the middle of the full-year plan leaves room for 4.5% expense growth from a year ago in the fourth quarter, absorbing the 4.6% September union wage hike.
Unchanged. Nine-month trading and treasury margin reached R$3.08 billion after a R$1.33 billion third quarter. By our math, reaching the R$4.0 billion middle of the range requires R$924 million in the fourth quarter, compared with R$597 million in the fourth quarter of last year.
