According to CNBC , CME is the largest derivatives exchange operator in the world, so this disruption has been felt in cities as far away as London and Kuala Lumpur. This exchange lets you trade almost everything on the market, including agriculture, energy, equity indices like S&P 500 and Nikkei 225, foreign exchange, interest rates, metals, crypto, and more.
