The Prague Stock Exchange, in a bid to increase liquidity and investor interest, is planning to open a derivatives market in the second half of the year, according to Vladimir Ezr, secretary general deputy and director of trading in Prague. He said the exchange is awaiting approval from the Czech Securities Commission, which should happen in the coming months, before going forward with the plan later in the year. The market would consist of listed derivatives, likely for local interest rates and the index, Ezr said. He said it could encompass other products as well, though he declined to speculate given the plan has yet to be approved by local regulators.
