Citigroup is a zombie company. It was a too-big-to-fail bank that nearly collapsed during the Global Financial Crisis in 2007-2008 but was rescued by the central bank. In order to persist, C needed decades of limitless monetary easing. Now, in the face of record inflation, the central bank's money lifeline is being challenged in unprecedented ways. In order to continue helping zombie banks, the central bank has to effectively increase the money supply. Increasing the money supply at a time of record inflation is risky business. The central bank will likely face a crisis of some kind: a severe liquidity crisis or an inflationary spiral... perhaps both.
