Why are there so many stock exchanges in the world?
Stock exchanges have been undergoing a period of consolidation for the past hundred years for the exact reasons you mentioned. The existence of digital trading, harmonized laws and regulations, and fewer relevant currencies have made it more practical for mergers and acquisitions between exchanges. Stock exchanges are most often times private companies that compete with other exchanges, so that also promotes the existence of many exchanges.
