Financial meltdown

Seems that most businesses will be affected by the current financial tsunami. USA has been managing its economy like a big ponzi scheme and when there is no more takers (or suckers) to play, the scheme just shut down. What will happen to Malaysia? If we were to evaluate the current conditions, our banks are not exposed to the financial derivatives, which is the main cause to the current meltdown. But then, why are some of the banks still pursuing some investment schemes which are based on US currency? Should we consider gold dinar and euro currency to trade?
