City Index is a global provider of spread betting, contracts for difference (CFD) trading and foreign exchange (FX) trading services. Founded in the United Kingdom in 1983, it currently operates as part of the Nasdaq-listed financial services group StoneX. City Index serves retail clients globally, holding regulatory licences from the Financial Conduct Authority (FCA) in the UK, the Australian Securities and Investments Commission (ASIC) in Australia, the Cyprus Securities and Exchange Commission (CySEC), the Monetary Authority of Singapore (MAS), and the UAE's Capital Market Authority (CMA). Initially focusing on spread betting, City Index expanded its services from the early 2000s, acquiring several other brokerage businesses and establishing international offices in Asia and Australia. The company experienced substantial financial difficulties during the 2008 financial crisis, leading to restructuring and eventual acquisition by GAIN Capital in 2014. GAIN Capital itself was later acquired by StoneX Group in 2020, making City Index part of StoneX's retail brokerage division.
