- R$ 4.9 billion is the potential amount that could be added to the earnings of the most liquid companies on the B3 stock exchange as interest rates fall.
- Utilities (electric power and sanitation) account for the largest share of this relief because they carry large volumes of CDI-linked debt.
- Higher free cash flow means an immediate improvement in accounting net income, which serves as the basis for dividend payments.
A study featured by InfoMoney mapped the capital structures of publicly traded companies and concluded that monetary easing could return billions of reais to corporate balance sheets. For investors focused on passive income, lower financial expenses have a practical and direct effect on the dividend per share.
How Can Lower Interest Rates Inject R$ 4.9 Billion into Corporate Earnings?
By directly reducing the net financial expenses of indebted companies. As the InfoMoney study pointed out, the calculation evaluated the exposure of the most liquid companies on the B3 to floating-rate liabilities indexed to the CDI and inflation (IPCA), subtracting cash and cash equivalents.
When the Selic rate declines, CDI-linked debt service falls at the same pace, requiring less cash outflow to pay creditors and debenture holders. Because this expense comes directly out of a company's financial results, every real saved on interest flows almost entirely into pre-tax income.
The effect mapped by the study focuses precisely on net positions, avoiding distortions in companies that hold significant cash balances earning floating rates. The final balance points to an aggregate gain of up to R$ 4.9 billion in corporate results.

Why Do Utilities Lead the Study's Gains?
Because they operate with high structural leverage and long-term debt contracts. Electric power generation, transmission, distribution, and basic sanitation concessions require heavy investments in physical assets before they begin operations, financing their construction through robust local debenture issuances.
This corporate debt is predominantly indexed to the CDI or inflation plus a spread. When the cost of money declines, the amount these concessionaires must provision for financial expenses shrinks significantly, without their operating revenue suffering sharp swings, as tariffs are indexed by stable concession contracts.
Unlike cyclical companies, which must rely on a recovery in consumer spending to boost revenue, utilities experience a turnaround in financial results without depending on an immediate jump in economic activity. Operating and financial cost savings arrive in the exact same quarter as the rate cut.
What Determines Whether This Interest Savings Becomes a Dividend?
The distribution policy and the need for new capital expenditures. Not every cent of saved interest automatically lands in the investor's bank account as a distribution, as management teams must evaluate their amortization schedules for past commitments and expansion plans.
Even so, because minimum mandatory dividends and the practices of the B3's top payers are calculated as a percentage of accounting net income (the payout ratio), arithmetic earnings growth tends to drive nominal distributions higher. If the accounting base jumps with interest relief, the slice reserved for dividends and interest on equity (JCP) gains proportional traction.
For investors seeking passive income, the distinction between revenue growth and financial cost containment is critical. A company that earns more because it pays less interest to banks keeps its operations intact and generates unencumbered additional cash.
- Payout indexed to earnings: Companies that maintain a fixed distribution of 50% to 100% pass on the gains without requiring new shareholder meetings.
- Predictable operating margin: Transmission and generation companies do not suffer sales contractions during monetary transitions, preserving cash flow.
- Debt rollover needs: Older issuances contracted with high spreads may require additional costs if the credit market demands a higher risk premium.
- Ongoing auctions: Companies with an appetite to bid for new concessions may choose to retain extra cash to finance future capital expenditures (CapEx).
What Does This Mean for Your Portfolio?
It changes dividend yields and relative valuations compared to government bonds. With high Selic rates, many investors migrated to Tesouro Selic or private floating-rate bonds, causing price devaluations for companies considered defensive on the B3.
Utility investors could see a dual recovery: higher dividends per share and a positive stock price revaluation. As returns on conservative fixed-income investments cool, the growing dividends of these concessionaires will likely attract institutional capital back, compressing dividend yields through stock price appreciation.
The studied trend reinforces the principle that monetary cycles affect companies in two ways: through consumer spending and through the cost of existing debt. In the first case, the response takes months; in the second, cost cuts appear on the very first income statement released after the benchmark rate changes.
What to Watch in Upcoming Quarterly Reports
Three metrics are essential to confirm whether the relief has translated into reality. Investors do not need to wait for a complete interest-rate cycle to validate the study; quarterly financial statements released by publicly traded companies to Brazil's securities regulator, the CVM, already signal this trajectory.
Net financial expense — compare quarter-over-quarter to see if the amounts paid for debenture and bank loan charges are declining in nominal terms.
Debt indexation profile — check the explanatory notes on financial instruments to verify the exact proportion indexed to the CDI versus fixed-rate or dollar-denominated debt.
Interest coverage ratio — review the metric of net debt divided by EBITDA to check whether the solvency structure is opening room for an effective increase in payout ratios.
By monitoring these three items, shareholders can identify which companies are converting macroeconomic rate cuts into free cash and dividends in their pockets, separating firms that pass on the relief from those using it merely to plug excessive leverage.
