"Citigroup said Wednesday it plans to pursue an initial public offering of its Mexico business, Banamex, scuttling a 16-month effort to find a buyer for the unit. The bank expects to complete the separation in the second half of 2024, with a public offering likely to follow in 2025, Citigroup said in a release. It hasn’t yet decided on a listing destination, but a dual listing in Mexico and the U.S. is possible, a source familiar with the plans told CNBC."
