The big five, which recently helped the world through financial crisis but are now experiencing marked growing pains, are Brazil, Russia, India, China and South Africa, the BRICS.
On their heels come the MINT, PPICS and CIVETS: acronyms created by economists and investors to describe groups of countries of similar type which could lead the next wave of emerging energy.
Last week more signs of economic tensions became evident in China and Brazil, just as the French trade insurance group Coface produced its list of what it called "neo-emerging" economies: the PPICS.
All of them have strong growth potential exceeding 4.0 per cent, diversified economies, are not unduly dependent on exporting raw materials and have financial systems capable of supporting growth and of absorbing a degree of external shocks.

Coface came up with a second list of countries, making 10 in all, comprising Kenya, Tanzania, Zambia, Bangladesh and Ethiopia.
These countries also offer growth potential but carry higher intrinsic risks.
Coface said that analysis of which countries, albeit smaller than the big five, could take over as leading emerging economies was needed because the big five were losing their competitive edge and had not yet become competitive in producing high valued-added goods and services.
Economist Jim O'Neill put the term BRIC on the map when he was an economist at US investment bank Goldman Sachs. He has now identified a new group, called MINT, comprising Mexico, Indonesia, Nigeria and Turkey.
The Economist Intelligence Unit has let loose another animal, going by the name of CIVETS, for Colombia, Indonesia, Vietnam, Egypt, Turkey and South Africa.
