@f4d89779: Got it. According to the World Federation of Exchanges, the top ten stock exchanges in the world by market capitalization as of 2021 are:
1. New York Stock Exchange (NYSE) - $28.5 trillion
2. NASDAQ - $17.5 trillion
3. Tokyo Stock Exchange (TSE) - $6.2 trillion
4. Shanghai Stock Exchange (SSE) - $5.0 trillion
5. Hong Kong Stock Exchange (HKEX) - $4.4 trillion
6. Euronext - $4.1 trillion
7. Shenzhen Stock Exchange (SZSE) - $3.9 trillion
8. Toronto Stock Exchange (TSX) - $2.3 trillion
9. Bombay Stock Exchange (BSE) - $2.2 trillion
10. National Stock Exchange of India (NSE) - $2.2 trillion
As for the total value of all markets, that's a bit more difficult to determine as it would require adding up the market capitalization of all stock exchanges, as well as the value of all currencies, commodities, and derivatives. Do you have a specific source or estimate in mind?
