There was also Islamabad stock exchange with about 20 billion USD market cap.
The idea was to usher in an era of privately owned and operated stock markets so that the necessary investment in upgrading the infrastructure of the exchanges could be mobilised and superior oversight could restrain the power of the large brokers to manipulate the market and engage in unethical trading practices.
The integration of the three exchanges is an essential step in that direction. With three separate stock markets, and with one of these dominant, the search for a private investor was complicated because it was hard to find an interested party for the Lahore and Islamabad exchanges, given their tiny size, and any private investor was wary of acquiring ownership of one exchange in Karachi while the other two remained in government hands.
