UBS Poll Aggregator Places Flávio Bolsonaro at 50.4 Percent Against Lula at 49.6 Percent in Projected Runoff
UBS data shows a statistical tie in Brazil's presidential runoff that directly affects sovereign debt costs and regional political alignment. Primary polling and market positioning indicate fiscal credibility will determine whether real rates fall 250 basis points or remain elevated. The simultaneous legislative elections will constrain whichever candidate prevails.
The 4 October first-round vote and subsequent runoff will determine control of the Chamber of Deputies and two-thirds of the Senate simultaneously, locking in the legislative arithmetic for any fiscal adjustment. UBS baseline forecasts remain unchanged until after both rounds conclude.
UBS: Real interest rates fall below 6 percent within six months only if the elected government passes primary-surplus legislation by Q1 2027.
