In a move that reverberates through both ethical investing and global energy markets, Norway’s Government Pension Fund Global (GPFG)—the largest sovereign wealth fund in the world—has announced the complete divestment of its fixed-income holdings in Mexico’s state-owned oil giant Petróleos Mexicanos (Pemex). The decision, made public on Sunday, stems from longstanding corruption concerns linked to Pemex's operations between 2004 and 2023.
