Introduction
Banco do Brasil (BBAS3) is one of Brazil’s largest and oldest financial institutions and one of the major banking companies listed on B3, Brazil’s stock exchange.
Because of its size, market presence and exposure to Brazil’s financial system, the stock is frequently monitored by investors looking for established companies and potential shareholder returns.
But an important question remains:
Is BBAS3 actually cheap, or is the market discount reflecting significant risks?
Answering that question requires more than simply looking at the share price. Bank analysis should consider net income, return on equity, credit quality, delinquency, valuation and the broader economic environment.
This article provides an educational analysis based on the latest information available for the second quarter of 2026.
Disclaimer: This article is provided for educational and informational purposes only. It does not constitute investment advice or a recommendation to buy or sell securities. Investing in stocks involves risk, and investors should consider their own financial situation and risk tolerance.
1. What is Banco do Brasil?
Banco do Brasil is a major Brazilian financial institution with operations covering banking services, lending, investments, insurance and agricultural financing.
Its common shares trade on B3 under the ticker BBAS3.
The bank maintains an Investor Relations website where investors can access financial statements, market announcements, shareholder remuneration information and other corporate documents.
2. How did Banco do Brasil perform in 2Q26?
In the second quarter of 2026, Banco do Brasil reported adjusted net income of approximately R$3.9 billion.
The result increased compared with the same period of the previous year and also improved compared with the first quarter of 2026. Gross financial margin reached approximately R$27.5 billion, while the expanded loan portfolio surpassed R$1.3 trillion.
Adjusted net income for the first half of 2026 reached approximately R$7.3 billion.
These figures demonstrate that the bank remains highly profitable. However, they do not tell the whole story.
The main concern is credit quality.
3. Delinquency is a key risk
One of the most important indicators for bank investors is loan delinquency.
In the second quarter of 2026, Banco do Brasil’s non-performing loan ratio above 90 days reached 5.61%. In agricultural lending, the ratio was approximately 6.27%. Delinquency among individuals also remained elevated.
This helps explain why a stock can trade at apparently low valuation multiples and still not be an obvious investment opportunity.
When delinquency increases, banks generally need to increase provisions for expected credit losses. This can reduce earnings and, consequently, return on equity.
For this reason, investors should monitor not only reported earnings but also the quality and sustainability of those earnings.
4. Agricultural lending deserves special attention
Agriculture is particularly important to Banco do Brasil.
As of June 2026, the bank’s agricultural credit portfolio stood at approximately R$421.6 billion, with delinquency at around 6.27%.
Weather conditions, crop losses, commodity prices, producer indebtedness and debt restructuring can all affect the bank’s results.
Government measures aimed at restructuring rural debt are also important because they can influence credit recovery and future provisioning requirements.
Therefore, BBAS3’s performance depends not only on management decisions. Macroeconomic conditions and the health of Brazil’s agricultural sector also play an important role.
5. ROE is essential when evaluating banks
ROE, or return on equity, measures how efficiently a company generates earnings from shareholders’ equity.
For banks, it is one of the most important profitability indicators.
Banco do Brasil reported an ROE of approximately 8.3% in 2Q26.
Although this represents an improvement, it remains below the profitability levels achieved by some major private Brazilian banks.
That helps explain part of the valuation discount applied to BBAS3.
A bank trading at a low price-to-book ratio can be attractive when it generates strong returns on equity. However, when ROE is low, the market may be signaling that the bank’s equity base is not currently generating sufficient earnings.
6. P/E and P/B: Is BBAS3 cheap?
From a valuation perspective, BBAS3 stands out.
The price-to-earnings ratio (P/E) was around 9 times based on the figures considered in this analysis.
The price-to-book ratio (P/B) was close to 0.6 times.
A P/B below 1 means the market is valuing the shares below their accounting book value.
That can represent an opportunity, but the indicator should not be analyzed in isolation.
For banks, the combination of:
Low P/B + high ROE
can be particularly attractive.
On the other hand:
Low P/B + low ROE + high delinquency
requires much more caution.
Banco do Brasil currently looks closer to the second scenario.
7. Is EBITDA useful for BBAS3?
Not particularly.
This is important because investors sometimes use the same valuation methodology for companies in completely different industries.
EBITDA is widely used for industrial, retail and service companies. For banks, however, it is not one of the most useful indicators.
Interest income and interest expenses are fundamental components of a bank’s business model.
For BBAS3, investors should focus more on:
- net income;
- ROE;
- net interest income;
- credit costs;
- provisions;
- delinquency;
- loan growth;
- efficiency;
- regulatory capital;
- P/E;
- P/B;
- dividends and interest on equity.
8. What about operating cash flow?
Operating cash flow also needs to be interpreted differently for banks.
For traditional companies, operating cash flow can help investors determine whether accounting earnings are being converted into cash generation.
For banks, however, changes in deposits, lending and other financial operations can produce large cash-flow variations that do not have the same meaning as they do for an industrial or service company.
Therefore, for BBAS3, investors should give greater weight to asset quality, profitability, capital strength, delinquency and sustainable earnings generation.
9. Five factors to monitor before investing in BBAS3
A fundamental analysis of Banco do Brasil can be summarized into five major factors.
1. Earnings
The bank needs to demonstrate the ability to recover and grow earnings over time.
2. ROE
The bank should generate an adequate return on shareholders’ equity.
3. Delinquency
The evolution of delinquency is essential to understand credit risk.
4. Valuation
P/E and P/B can help determine whether the price paid for the stock appears reasonable relative to earnings and book value.
5. Macroeconomic conditions and agriculture
Interest rates, economic activity, employment, inflation, weather conditions and agricultural credit conditions can directly affect the bank’s results.
10. So, is BBAS3 cheap?
The answer depends on the investor’s assumptions and investment horizon.
Based on valuation multiples, BBAS3 appears discounted, particularly because its P/B ratio is close to 0.6.
However, there is a reason for that discount.
The bank is facing pressure on credit quality, especially in agricultural lending, while ROE remains below levels that would normally support a higher valuation multiple.
The second quarter of 2026 showed positive signs, including adjusted net income of R$3.9 billion and ROE of 8.3%, but delinquency remains one of the major obstacles to a stronger recovery in profitability.
Therefore, the key investment question is not simply:
“Is BBAS3 cheap?”
It is:
“Can Banco do Brasil recover profitability and reduce credit costs?”
If the answer is yes, the current valuation discount could represent an interesting opportunity.
If credit deterioration continues, the stock could remain cheap for a long period.
Conclusion
Banco do Brasil has characteristics that may appeal to fundamental investors: large scale, a strong position in the Brazilian financial system, a substantial equity base and relatively low valuation multiples.
At the same time, investors should not ignore the risks.
Credit quality is the main issue, particularly because of the bank’s significant exposure to agricultural lending. High delinquency can increase provisions and limit ROE recovery.
Therefore, BBAS3 can be viewed as a potentially interesting value stock, but one that requires close monitoring of credit quality and profitability indicators.
Future quarterly results will be important to determine whether the improvement seen in the second quarter of 2026 represents the beginning of a sustainable recovery or only a temporary improvement.
