For the past 70 years, the International Monetary Fund and the World Bank have been the pillars of the world's economic system, coming to the rescue of countries in trouble and supporting development projects, respectively.
But the Bretton Woods institutions are regularly criticised for their inability to reflect the growing and important contributions of the major emerging economies to the global economy.
China, the world's second-largest economy, continues to have just slightly more voting power in the IMF than Italy, about five times smaller.
"Broader global governance reforms have become stalled, despite the many commitments made by advanced economies to emerging markets to give them a more prominent role in international financial institutions and other international forums," said Eswar Prasad, a trade policy professor at Cornell University and a former IMF expert.

In this context, the launch Tuesday of a development bank and an emergency reserve fund by the BRICS - Brazil, Russia, India, China and South Africa - appears to be a concrete attempt to address those inequities.
The mere creation of the two BRICS institutions sends a strong signal to Western powers, where some doubt the ability of the five powerhouses to surmount their individual needs and ambitions.
The launches "are significant actions that represent a game changer as they turn statements and rhetoric about cooperation among these countries into reality," Prasad said.
For now, only the BRICS countries will be able to draw from the USD50 billion in the New Development Bank and USD100 billion in the Contingent Reserve Arrangement.
