Problems of financial powers keep prices up
According to some European and American analysts, nations of the world have been regrouped into a new "three-world fixture": developed countries have turned into financial powers while developing nations have become manufacturing powers and exporting powers of energy and materials resources.
Before the prices of production materials shot sky high, the opening up of the global market brought by the liberalization of international trade created an opportunity for manufacturing powers to develop further and they grew the fastes. That said, as the prices of production materials soared, the financial powers and energy- and materials-exporting powers seemed to be doing even better than manufacturing powers.
Financial powers and especially the US have a kind of currency hegemony. The US dollar is the leading currency in the world and the pricing currency for many bulk commodities such as oil. When the US dollar depreciated, the prices of such commodities went up. There is a mechanical co-relation between them.
