Citigroup has cut 200 to 300 jobs, or about 2 percent of its global markets workforce, The Wall Street Journal reported citing a person familiar with the matter.
The bank is tightly managing expenses and "making targeted head count reductions in light of current market conditions,'' the Journal quoted a company spokeswoman.
Steve Prince, the younger brother of former Citigroup Chief Executive Charles Prince, was among those who lost their job, the report said.
