On Wednesday, October 11, the dollar started the trading session marginally higher, rising 0.02% to be traded at R$ 5.1581 around 9:05 AM. This increase is occurring in the context of heightened investor attention to international developments, particularly in the Middle East. Although U.S. President Donald Trump claimed the war was 'practically over' the day before, the region saw intensified airstrikes by the U.S. and Israel against Tehran, marking some of the most severe actions in the ongoing conflict.

The Iranian Revolutionary Guard responded to these airstrikes by threatening to block oil shipments from the Persian Gulf, highlighting the fragile state of the oil market. The Strait of Hormuz remains a critical chokepoint for global oil transportation, and any disruption in this area could significantly affect oil supply and, consequently, global prices. Investors are closely monitoring these developments, as potential restrictions on oil shipments may lead to serious fluctuations in commodity prices worldwide.

As the Brazilian stock market prepares to open around 10 AM, there are concerns about the broader implications of Middle Eastern conflicts on global market dynamics. With Brazil's economy closely tied to commodity prices, particularly oil, fluctuations in the dollar and local stock indices are indicative of how external geopolitical issues can have immediate impacts on Brazil's economic landscape.
