Debate and experimentation are on-going, regarding the introduction of central bank issued digital currencies (CBDC) amongst central bankers. Some countries are more advanced in their CBDC work while others are still on the drawing table. Examine the pace of CBDC progress in these countries --- Singapore, US and China and rank their relative progress. Discuss and explain the factors behind the differences in pace of CBDC progress in these three countries. Make good uses of examples, statistics and events to augment and conclude your discussion.
