Is this the death of the dollar?

After two smugglers were stopped last week with what at first appeared to be $134bn in US state bonds, the tension and paranoia surrounding the fate of the dollar hit a new high.

The dollar's fate is intertwined with that of the global economy

Border guards in Chiasso see plenty of smugglers and plenty of false-bottomed suitcases, but no one in the town, which straddles the Italian-Swiss frontier, had ever seen anything like this. Trussed up in front of the police in the train station were two Japanese men, and beside them a suitcase with a booty unlike any other. Concealed at the bottom of the bag were some rather incredible sheets of paper. The documents were apparently dollar-denominated US government bonds with a face value of a staggering $134bn (£81bn).

How on earth did these two men, who at first refused to identify themselves, come to be there, trying to ride the train into Switzerland carrying bonds worth more than the gross domestic product of Singapore? If the bonds were genuine, the pair would have been America's fourth-biggest creditor, ahead of the UK and just behind Russia.
