…Currency traders had a not-so-great year: The largest currency trader in the world by market share is Citigroup, according to a Euromoney Institutional Investor survey. This is the third straight year Citigroup led the ranking, Bloomberg says. It had a 12.9% market share and was followed by JPMorgan Chase & Co, UBS, and Deutsche Bank. Overall, trading volume dropped 23% from last year “and the top five banks’ share of the market plummeted to an all-time low.” What’s really interesting in the survey is that XTX Markets, a London-based computerized trading firm, came in ninth place in the survey in its debut. The market as a whole is under pressure: “Concern about the outlook for the U.S., Europe and China, as well as mixed policy signals from central bankers around the world, have contributed to what UBS Chief Executive Officer Sergio Ermotti called a ‘paralyzing volatility’ that’s scared away clients and caused industry-wide trading revenue to tumble to the lowest since 2009.” This is reflected in a large number of job cuts, and created a “void” in foreign-exchange liquidity and foreign-exchange credit-line markets that is being filled partially by non-bank firms.
