After the latest global slowdown and financial crisis, a debate is going on, on "Dollar Hegemony". 'What does it really mean ? In simple terms
(A)it is the trade practice prevalent all over the world in which USA provides dollars and the rest of the world manufactures the commodities which dollars can purchase.
(B) it is the situation in which all the nations are forcefully required to evaluate their local currencies against the value of the dollars. Hence countries are forced to keep as many dollars as they can to operate safely in global markets.
(C) now economists all over the world are trying to nd out a solution to come out of this dollar trap as this hegemony prevents exporting nations from spending domestically the dollars they have earned from USA.
