Brazil’s Copom is widely expected to deliver a fifth consecutive 25-basis-point Selic cut to 13.75% at its September 16 meeting, producing the 99.3% market-implied probability for that outcome. The consensus rests on recent disinflation, with the August IPCA print showing a 12-month rate near 4.25% alongside moderating economic activity and trimmed 2026 growth forecasts. Policymakers have framed the easing as data-dependent calibration while keeping policy restrictive relative to the 3% inflation target. Surveys from Bloomberg and Valor show near-unanimous analyst support for the quarter-point move ahead of the presidential election. A hold or larger adjustment remains possible only if fresh data or oil-price pressures prompt a sharper focus on upside inflation risks, though such scenarios currently carry negligible market weight.

The resolution source will be official information from the Bank of Brazil, including the statement or release from its September 2026 Monetary Policy Committee meeting, scheduled for September 14-15, 2026, as listed on the official Bank of Brazil calendar (https://www.bcb.gov.br/en/about/bcb-calendar?categoria=Monetary%20Policy%20Committee%20(Copom)). This market may resolve as soon as the statement or release of the Bank of Brazil's September 2026 Monetary Policy Committee meeting with relevant data is issued.
If the specified rate is defined by an upper and lower bound, the relevant change will be the change to the upper bound.
If the specified rate is changed to a level not expressed in the displayed options, the change will be rounded according to the following guidelines. Increases or decreases of less than 25 bps will be rounded to 25 bps (e.g. an increase or decrease of 10 bps would be considered to be an increase or decrease of 25 bps). Increases or decreases of greater than 25 bps will be rounded to the nearest 25 bps and will be rounded away from 0 in cases of equidistance (e.g., an increase or decrease of 37.5 bps would be considered to be an increase or decrease of 50 bps). Displayed options of “Increase” or “Decrease” will include policy rate increases or decreases of any size.
If the specified meeting is postponed to a date and time before the start of the next scheduled meeting, this market will resolve based on the outcome of that postponed meeting. If the specified meeting is cancelled, or postponed such that no decision is announced by the start of the next scheduled meeting, this market will resolve to the “No Change” bracket. Emergency changes to the specified rate not resulting from the specified meeting will not be considered.
