Which exchange is known as the first pan-European exchange?

Euronext is recognized as the first pan-European exchange because it was formed through the merger of various national exchanges in Europe, specifically Amsterdam, Brussels, and Paris. This integration aimed to create a unified marketplace that fosters cross-border trading and enhances liquidity, allowing investors access to a broader array of stocks across multiple European countries from a single platform. The establishment of Euronext marked a significant step in the evolution of European financial markets, promoting efficiency and connectivity among different national markets.

In contrast, the other exchanges mentioned do not share the same pan-European characteristic. SGX (Singapore Exchange) primarily serves the Asian market, JPX (Japan Exchange Group) focuses on Japan, and LSE (London Stock Exchange) is a major exchange but does not encompass multiple European countries as part of its operational framework in the same way Euronext does.
