The Brazilian dollar opened at a slight decrease of 0.24%, trading at R$ 5.2336, after a substantial increase of 1.67% the day before. Investors are closely monitoring the implications of the ongoing conflict in the Middle East, particularly its impact on oil prices and global economic stability. This concern was heightened after a new wave of Iranian attacks on oil and transport facilities raised fears of a prolonged conflict and potential disruptions in oil supply through the Strait of Hormuz.

In addition to geopolitical factors, the market is reacting to the announcement from the US government investigating Brazil and over 60 other countries for forced labor practices. This could lead to new import tariffs, adding to the economic pressure within Brazil. Following the spike in the dollar's value on Thursday, which culminated in the Brazilian stock market dropping by 2.54%, investors are wary of potential repercussions from these international developments.

The ongoing volatility and risk aversion among investors highlight the intertwining effects of domestic and international issues on Brazil's economy. With oil prices once again exceeding $100 per barrel, the strength of the dollar, and Brazil's engagement in international trade contracts could significantly shape economic policies and investor confidence in the upcoming weeks.
