    While liberalisation essentially involves dismantling the barriers to entry and exit and the lifting of controls, it does not automatically imply no regulation at all. In fact, regulation assumes its own level of sophistication in terms of letting the system operate without unnecessarily restraining it, while at the same time protecting the financial system from its own excesses. In the banking sector, for instance, while liberalisation can bring about a removal of barriers on the entry of new banks and credit restrictions, it is accompanied by a more stringent set of prudential, supervisory and regulatory structure. Similarly, in the area of capital market, while liberalisation could mean the opening up of markets to new products and new participants, regulation is put in place to protect investors' interests and no prevent excessive speculation. The financial system needs to have some regulation even in a free-market economy.
