First, we can expect that Asia's share of the world economy will continue to grow. For various reasons, Asian nations have traditionally had a higher rate of savings than other economies.

The reasons this has not happened include: –  lack of commitment of the Primary Dealers to undertake Government securities transactions as a line of business  –  the weak financial strength of licensed brokerage firms that do not have the required wide net work to reach the non-bank public  –  over 80% of Government securities are taken up and held by Banks.
