Brent took +4.81% to $105.99 today. This increase echoes the failed attempt of the President of the United States Joe Biden to convince the Saudi Crown Prince Mohammed Ben Salman – and through him the Organization of the Petroleum Exporting Countries (Opec) – to open the black gold tap more widely. His desire to loosen the grip of inflation that strangles household finances in the United States has not been fulfilled for the moment in any case. Over the past year, the price of a barrel of Brent has increased by 41.43%, from 64.60 to 139.13 dollars.
