Except for the price of foreign oil - and that is another story - surging foreign currencies means products from those countries will be more expensive in the US and US products will be cheaper in those countries - unless those governments raise tarriffs to protect their products.
The US consumer hardly notices monetary exchange rates unless he buys foreign goods. In addition, travel abroad may be more expensive.
The biggest danger is that foreign countries which hold US dollars may start dumping those dollars for more attractive, valuable currencies. However, with the US government one of the most stable in the world and the strength of the US economy, vast dumping of US dollars is doubtful.
Maybe what is going on will force China to float it’s own currency?
