Oil prices surpassed the $100 mark again this Monday, April 13, due to escalating tensions between the US and Iran. Following the collapse of negotiations between the US delegation, including Vice President JD Vance, and Iranian officials, Donald Trump announced a blockade of Iranian ports. This move aims to cut off a major source of funding for the Iranian state, with the US Navy on high alert in the region. The situation has created significant market uncertainty, threatening global crude supply and driving up prices, while oil company stocks like Galp Energia continue to see gains.
