Global oil prices fell significantly on Friday following the announcement that the Strait of Hormuz has been reopened to commercial traffic. While European stock markets saw gains, the Lisbon stock index, the PSI, fell as energy companies like Galp experienced an abrupt correction in share prices. The reopening follows a ceasefire agreement between Israel and Lebanon, though the long-term stability of the route remains a focus for investors.
