Dollar firms to R$5.22 as Trump rejects Iran ceasefire, Brazil election polls weigh

The dollar strengthened against the Brazilian real to R$5.22, driven by global risk aversion after President Trump rejected a ceasefire with Iran, pressuring US bonds and oil. Domestic factors, including a Quaest poll favoring Lula, limited the real's gains from higher commodity prices. The move reflects a shift in sentiment as external geopolitical risk and local election uncertainty converge.
