That move comes just two weeks after Afreximbank, as it is known, excited the City by saying it wanted to tap London’s capital markets as part of expansion plans. While City watchers questioned why banking advisers at JPMorgan and HSBC could advise a U-turn in such a short space of time, they acknowledge that markets have been turbulent, making floats risky. WeWork pulled a $50 billion New York float at the end of September. Saudi Aramco is reportedly readying the largest ever stock-market listing after numerous false starts. In London, ditched floats include the £4 billion IPO of Kazakhstan tech firm Kaspi, which said in October that “unfavourable and uncertain market conditions, particularly in the technology sector”, made a shares sale impossible.
