The interest rate is one of the variables that most influences the Brazilian business environment. In this regard, Pedro Daniel Magalhães—a finance executive and advisor—states that its effects on companies go far beyond the cost of credit: they shape investment decisions, define financing strategies, and largely determine which companies grow and which fall behind during high-interest-rate cycles.
In a country that has lived for decades with real interest rates among the highest in the world, understanding how this mechanism operates in the corporate environment is an indispensable skill for managers, investors, and financial market professionals.

How do high interest rates directly affect corporate investment decisions?
Every corporate investment decision goes through a viability analysis that considers the cost of capital. When interest rates rise, this cost increases, raising the minimum rate of return a project must offer to be approved. The result is a natural contraction of viable investment options: projects that would be profitable in a lower interest rate environment no longer pass the financial filter and are either discarded or postponed.
Pedro Magalhães is precise in noting that this effect does not only affect expansion decisions. Investments in technology, operational efficiency, and team training are also deferred during periods of high interest rates. The cumulative result is a company that grows less, innovates less, and becomes progressively less competitive compared to rivals operating in environments with a more favorable cost of capital.
The decision-making paralysis generated by high interest rates is one of the least visible yet most damaging effects on the competitiveness of Brazilian companies. As soon as managers spend more time managing liabilities than developing growth strategies, the business loses momentum and drifts away from market opportunities.
How do high interest rates reshape corporate financial strategy?
In high-interest-rate environments, corporate financial strategy must adapt. Liability management takes center stage, and decisions regarding the term, cost, and profile of debt become just as relevant as decisions regarding revenue and margins. Companies that fail to develop this capability leave themselves exposed to risks that could compromise their medium-term sustainability.
As Pedro Daniel Magalhães analyzes, the most resilient companies are those that diversify their funding sources, maintain leverage indicators within sustainable limits, and adapt their capital structure to market conditions at each stage of the economic cycle. These skills require investing in qualified teams, robust monitoring systems, and a culture that treats financial management as a strategic function.
The impact of interest rates on valuation is also direct. Since the discount rate reflects the cost of capital, an increase in interest rates reduces the present value of future cash flows and compresses corporate valuations. For Pedro Magalhães, this effect creates opportunities for disciplined acquirers who can identify undervalued assets and structure viable M&A transactions even in a more restrictive credit environment.
Interest rates, decision-making, and resilience: what separates companies that grow from those that merely survive
The impact of interest rates on Brazilian companies is inevitable, but its effects are not uniform. Companies that have developed disciplined financial management, diversified their capital sources, and treat the cost of credit as a central strategic variable manage to not only survive adverse cycles but emerge from them in a superior competitive position.
Pedro Daniel Magalhães reinforces that the difference between companies that grow and those that merely survive lies largely in the quality of the financial decisions made before the adverse cycle sets in. Structuring liabilities in advance, maintaining adequate liquidity, and developing solid relationships with multiple credit sources are practices that prove decisive when the environment deteriorates.
For managers, investors, and financial market professionals, understanding how interest rates shape corporate decision-making is a practical and indispensable lens for evaluating companies, identifying risks, and making more informed decisions in any market environment.
