Brazil pre-election: Datafolha poll and TV debate to drive market, Iran caution caps gains

Brazilian markets brace for election-driven volatility as a new Datafolha poll and a presidential debate on TV Globo are set to shape investor sentiment days before the first round. However, risk appetite is tempered by stalled US-Iran negotiations and Brent crude near $100 per barrel, which may limit domestic gains. The outcome of the poll and debate could shift electoral odds, while external geopolitical and energy pressures add a cautious overlay.
