High interest rates squeeze StoneCo ahead of third-quarter earnings
Payment processor StoneCo faces a critical test on November 12, 2026, as Brazil's benchmark interest rate remains at 13.75%, squeezing margins and testing its credit book.
American retail investors holding high-growth financial technology companies are facing a crucial test of how macroeconomic pressure can disrupt even the most promising business models. On Thursday, November 12, 2026, after the market closes, the payment processor StoneCo Ltd. is scheduled to release its third-quarter financial results. The upcoming report will spotlight how the company is managing its credit expansion under the weight of a high interest rate environment.
In Brazil, the central bank's benchmark interest rate, known as the Selic, stands at 13.75% as of November 2026. This high rate environment creates a direct mechanical headwind for StoneCo. The company funds merchant prepayments and a growing credit book, meaning its funding costs are highly sensitive to local interest rates. Management previously noted during its second-quarter earnings call on August 13, 2026, that every 100-basis-point increase in the Selic rate exerts a pretax profit headwind of approximately 200 million to 250 million Brazilian reais ($36 million to $45 million).
The macroeconomic pressure has already forced StoneCo to manage expectations. During its previous quarterly update, executives warned that the elevated rate environment would likely force full-year results toward the lower end of its guided ranges, which include an adjusted gross profit of 6.6 billion to 7.0 billion reais. Wall Street analysts expect the company to post third-quarter earnings of $0.48 per share on revenue of $715.69 million, representing a key test of whether merchant volumes can sustain corporate growth despite the rate squeeze.
This rate pressure is part of a broader post-election repricing across Brazilian financial assets. Following the October 2026 presidential runoff, in which Luiz Inácio Lula da Silva won a close victory over Flávio Bolsonaro, investors have closely monitored the country's fiscal path. To calm market jitters, Lula's economic team is preparing to submit a fiscal package to Congress aiming for up to 60 billion reais ($10.8 billion) in spending curbs for next year. How the government manages this fiscal transition will directly influence inflation expectations and the future trajectory of Brazil's central bank rates.
