The U.S. dollar has shown a firmer bias against most major currencies, with the exception of the Australian dollar, which remained steady following a 25 basis point rate cut by the Reserve Bank of Australia (RBA) to 4.10%. The RBA's decision was described as hawkish, with the next cut not fully anticipated until August. Meanwhile, the dollar's strength comes amid ongoing geopolitical uncertainties, including U.S.-Russia talks aimed at resolving the Ukraine conflict, and concerns over potential U.S. tariffs. The dollar index rose by 0.2%. The euro and sterling experienced slight declines, while the yen weakened after recent gains spurred by expectations of a Bank of Japan rate hike. In Brazil, the dollar closed above R$ 5.70, influenced by tariff concerns and the ongoing war in Ukraine, closing at R$ 5.7128. The Brazilian stock market, represented by the Ibovespa, saw gains of 0.68%.
