Macro needs Argentina to heal

01 Running thesis

A bank tied to Argentina's turn

Banco Macro's upside starts with a simple idea: Argentina has very low banking use, and lending can grow fast if inflation falls, rules get clearer, and households and companies borrow again. BMA has the capital to fund that growth. It also has a deposit base that can be cheap when customers keep money in everyday accounts.

The story has cooled. Management cut its 2026 outlook to 20% real loan growth and 6% real deposit growth. That is still growth after inflation, but it is much lower than the much bigger targets management discussed earlier in 2025.

The profit picture is also not clean yet. Lower real interest rates and a slow economic pickup can hold down earnings. Management is working around an 8% adjusted ROE for 2026, and the internal view does not expect the full restructuring benefit and a return to mid-teen ROEs until 2028, when inflation accounting adjustments are expected to stop.

Digital expansion is the main extra option. BMA bought 50% of Personal Pay, Telecom Argentina's wallet, and agreed with Fintech Digital LLC to jointly acquire Banco Sáenz S.A. These moves could help the bank reach more customers without only relying on branches.

Apr 2026The 2026 20-F confirmed the planned joint acquisition of Banco Sáenz and said most foreign exchange restrictions were eliminated in April without major difficulties. That supports the digital and macro normalization parts of the thesis.
Feb 2026Management cut 2026 expectations to 20% real loan growth and 6% real deposit growth, and guided to about 8% adjusted ROE. It also set 2026 cost of risk near 5.2% and NPLs in the mid to low 3s area.
Dec 2025Q3 2025 showed worse credit pressure, with cost of risk at 6.5% and NPLs expected to peak around October or November. Management also lowered its 2026 real loan growth forecast to 35%.
Aug 2025Management kept a strong 2025 loan growth target and introduced a 45% real growth target for 2026. The offset was rising credit risk, with NPLs expected to move toward 2.5% to 3% and cost of risk near 4% in the second half.
May 2025The thesis shifted toward faster movement from public assets into private loans and stronger deposit growth guidance of 45%. Profit expectations were lower, with 2025 ROE guided to 8% to 10%.
Apr 2025The 2025 20-F grounded the macro backdrop, including Argentina's 2.4% GDP contraction in 2024 after a 1.6% contraction in 2023. The case still depended on stabilization and loan growth.
Feb 2025Management raised 2025 real loan growth expectations to 60%, helped by faster consumer lending. The stronger growth came with higher expected cost of risk of more than 2% and possibly 2.5%.
Dec 2024Q3 2024 strengthened the growth case as management lifted 2025 real loan growth guidance to around 40%. Transactional accounts reached about 62% of deposits, helped by Tax Amnesty demand deposit inflows.
02 Business model

Cheap deposits fund loans

Banco Macro makes money like a classic bank. It takes deposits, pays customers an interest rate, and lends money at a higher rate. The gap is the spread. Fees from accounts, cards, payroll, payments, and other services add to that income.

The key asset is funding. Transactional accounts represented about 65% of total deposits at the end of 2024. These are everyday accounts, and they can be cheaper than term deposits. Argentina's Tax Amnesty also helped bring in demand deposits.

BMA keeps a very liquid, high-capital balance sheet. The 2026 20-F says it had excess regulatory capital of Ps. 3,614,321.3 million and a 30.6% capitalization ratio as of December 31, 2025. That capital can support loan growth, absorb shocks, or help fund deals.

The weak spot is the same one that creates the upside. Argentina's rates, inflation, currency rules, and government bond market can change quickly. BMA holds sovereign exposure partly to manage inflation effects, but that also ties the bank's health to the state.

03 Product portfolio

What Macro sells

Cash cow

Transactional deposits

Savings, checking, payroll, and demand deposits are the funding engine. Low-cost money lets the bank earn a spread when it lends or invests.

Growth engine

Personal loans

Personal lending is a core way BMA monetizes retail customers. In 2025, the bank said more than 1.5 million personal loans were granted.

Steady

Credit cards

Cards bring interest income, fees, and daily customer activity. The bank is trying to grow card use while watching credit losses.

Growth engine

SME and corporate lending

BMA lends to SMEs, agricultural companies, larger companies, and corporates. This can grow fast if Argentina's economy improves, but it is also where sector stress can show up.

Cash cow

Payroll services

Plan Sueldo payroll accounts give BMA stable customer relationships and deposits. The bank serves payroll and retiree customers for private employers and provincial governments.

Option

Personal Pay and bank-as-a-service

The 50% Personal Pay deal gives BMA a wallet-based growth path. Management described it as a bank-as-a-service business.

Option

Banco Sáenz digital ecosystem

The planned joint acquisition of Banco Sáenz is meant to expand BMA's digital ecosystem. It still depends on closing conditions and Central Bank approval.

04 Business segments

Customer mix, not profit segments

Companies42%modest
Individuals41%declining

Government2%growing fast

Banco Macro says in its 2026 20-F that it does not manage profitability by segment. The mix below uses its disclosed 2025 customer portfolio participation by banking segment, so it is a customer portfolio view, not a profit split.

05 Risk factors

What could break the case

Argentina macro relapse

High impact · Medium odds

BMA is mostly an Argentina bank. If inflation stays high, growth stalls, or confidence falls, households and companies may borrow less and repay worse. That would hit both growth and credit costs.

We watchArgentina inflation, real GDP growth, and management's real loan and deposit growth guidance.

Credit losses stay high

High impact · Medium odds

Asset quality has already been under pressure. Management expects NPLs in the mid to low 3s area and a 5.2% cost of risk for 2026. If those numbers move higher, the lending growth story becomes much less attractive.

We watchNPL ratio versus the mid to low 3s area, and cost of risk versus 5.2%.

Manufacturing stress spreads

Medium impact · Medium odds

Management called out textiles and automotive as sectors hurt by Argentina opening its economy. If stress spreads from those areas into more SMEs and employers, BMA could see more defaults and weaker payroll relationships.

We watchDelinquencies and loan restructurings in textiles, automotive, SMEs, and regional business clients.

Lower rates squeeze earnings

Medium impact · High odds

Lower real rates can help the economy, but they can also reduce bank spreads. Management is already working around an 8% adjusted ROE for 2026. That means near-term profits may lag the growth story.

We watchAdjusted ROE, net interest margin, and management comments on real rates.

Currency rules change again

High impact · Medium odds

The Central Bank eliminated most foreign exchange restrictions in April 2026 without major difficulties. That is positive for normalization, but it also changes currency risk. A new round of controls or a sharp peso move could hurt confidence and balance sheet planning.

We watchCentral Bank foreign exchange rules, peso volatility, and deposit behavior after policy changes.

Digital deals fail to pay off

Medium impact · Medium odds

Personal Pay and Banco Sáenz are meant to extend BMA beyond classic branch banking. These deals could help growth, but they also need integration, customer adoption, and regulatory approval. If they do not scale, the digital option is worth less.

We watchPersonal Pay customer activity, Banco Sáenz approval status, and updates on bank-as-a-service revenue.
