(This may be on economic section... but I feel it is more suitable on politics section) Dollar.
As recent incident, it is now really hard for US government and economy to protect the dollar as basic currency.
With recent financial incidents indicate that the value of dollar would further decrease, since US just spent some
good money on saving companies.
Now, with dollar value decreasing, this may change the minds of oil nations and give chance to Euro and/or RMB as new basic currency.
Well, Euro has been got stronger in recent years, but the crucial point would be when OPEC begins to regard Euro as major currency for trading the oil. Currently about 70% of oil trade is done via dollar, while other 30% is made of Euro (20%) and other currencies.
Big question is what will be happen if dollar is no longer major currency for oil trading, thus losing its status as basic currency in the world?
Or in less extent, what will be happen if all major banks more inclined to favoring mix of currencies for all the transactions? (for example, now you have to trade with some dollars, some euros and RMB together, not dollar alone like you could before)
As I understand, this means US will lose its control over world economics (well, the overall dollar value/storage in the world will decline since it wouldn't be necessary to keep and obtain the dollar,) and there won't be enough 'returns' for US economics for 'spending'. I am pretty sure there are other effects, but these two alone will cause some very undesirable consequences for the people of US (and of course it won't be good for my nation, since our new president is just idiot and underwhelming.)
I hope dollar would keep its position as same as today in future as well, but the chance to save dollar is getting slim; now the question is, are there any politicans ready for this? How about two US presidental candidates?
