The darkest sign yet for the US dollar

Never mind the fact that three of the world's biggest oil exporters (Venezuela, Russia, and Iran) are now demanding payment in euros. Now rap stars are moving in the same direction:

Wads of dollar bills are usually as much a part of rap videos as fast cars, diamond-encrusted jewellery and scantily-clad models.

But in an apparent nod to the low value of the dollar, rapper Jay-Z's new video Blue Magic features another currency.

He is seen cruising the streets of New York in Bentleys and Rolls Royces (now owned by Germany's Volkswagen and BMW) with a briefcase of 500 euro notes.

Time to sell your greenbacks now, folks.
