Brazil’s Ibovespa closed at 195,733.51 points on April 17, down 0.55% and accumulating a weekly loss of 0.81%, pressured by petroleum sector selloffs following Iran’s announcement of full reopening of the Strait of Hormuz. The dramatic reversal in oil prices, with Brent crude tumbling 9% to below $90 per barrel, erased approximately one quarter of Petrobras’s market capitalization gains accumulated since the onset of Middle East tensions.
