According to CoinMeta, as reported by the Portuguese national news agency Lusa, the Portuguese government has approved the imposition of a temporary windfall tax on oil extraction and refining companies. This tax measure was approved at a cabinet meeting on Thursday and will target the portion of corporate profits that significantly exceed the average levels of previous years. A spokesman for the Portuguese government confirmed this report. The move is aimed at alleviating the pressure of rising fuel costs on households and vulnerable businesses against the backdrop of the Iran war driving up fuel prices. It will also be used for investment to reduce dependence on fossil fuels. Following the announcement of the news, the stock price of Galp Energia, Portugal's largest listed company, fell by 3.2% on the Lisbon market.
