Itaú Unibanco Holding S.A. (ITUB) Balance Sheet

The balance sheet grew 23% from 2024Q1 to 2026Q2, with investment securities rising from $1.9T to $2.1T, indicating a strategic shift toward interest-bearing assets. Loan growth appears to be funded by securities sales and wholesale funding, as cash flow data suggest, while equity grew only 17%, implying increasing leverage. This expansion appears to be organic, with no evidence of M&A activity in the data.

The bank's funding advantage is evident in its stable net interest margin, which recovered to 0.7% in 2026Q2 from a low of 0.2% in 2025Q4, suggesting deposit betas remain favorable. The absence of explicit deposit data in the balance sheet table limits direct analysis, but the low-cost float from payroll accounts and high-net-worth deposits appears to support profitability. Investors should monitor deposit competition from digital banks, which could pressure funding costs.

The provision expense has remained elevated, reflecting high household leverage in Brazil and potential stress in retail portfolios. However, the stability of provisions relative to total assets (around 0.3%) suggests credit quality is not deteriorating sharply. The 90-day delinquency bucket is a key metric to watch, as it could signal future provisioning needs. The bank's ability to maintain ROE above 20% despite these costs indicates strong risk management.

The equity-to-assets ratio of 0.07 in 2026Q2 is low for a bank, but typical for Brazilian banks with high leverage. The debt-to-equity ratio of 4.71 is elevated, but for banks, this reflects deposit funding rather than industrial debt. Regulatory capital ratios (CET1) are not disclosed in the data, but the stable ROE of ~5% (quarterly) suggests adequate capital generation. The potential JCP tax deduction changes could reduce distributable income, impacting capital retention.

The bank holds a large securities portfolio, which can be sold to meet funding needs, as evidenced by net sales of $43.1B in 2026Q2. This suggests a reliance on wholesale funding and securities sales rather than core deposits, which are not directly visible. The loan-to-deposit ratio is not disclosed, but the cash flow data indicate loan growth is being funded by securities sales, implying a potential liquidity risk if markets tighten. However, the size of the securities book provides a cushion.

The extreme NIM volatility suggests the bank's earnings are highly sensitive to the SELIC rate, with rising rates initially expanding spreads but eventually increasing credit risk. The recovery in NIM to 0.7% in 2026Q2 may indicate a favorable rate environment, but the lack of updated guidance limits forward visibility. Investors should monitor deposit betas and loan repricing to gauge NIM trajectory. The efficiency ratio improvement to 21.5% suggests cost discipline, but revenue volatility remains a concern.
