Where Are Argentina's Coins?: This is for sure the strangest story of the week. Argentina is facing a mysterious coin shortage. Some small convenience stores would rather turn down business than give out change. Buying coins can require as much as a seven percent premium over face value, and markets owned by Chinese immigrants have banded together to issue their own currency.

America's AAA Rating Is At Risk: The U.S. has had the rating since 1917, but now Moody's is threatening to cut it. (How un-American.) I wonder, though, if anyone would care? Everyone knows the U.S. is the most financially reckless borrower in the world at the moment, but other countries still give us money hand-over-fist.

Are the Saudis Recession-Proof?: Perhaps not so much as we think.

Big Ships, Little Business: File it under fascinating: Near Singapore, "one of the largest fleets of ships ever gathered idles just outside one of the world's busiest ports, marooned by the receding tide of global trade...Hundreds of cargo ships — some up to 300,000 tons, with many weighing more than the entire 130-ship Spanish Armada — seem to perch on top of the water rather than in it, their red rudders and bulbous noses, submerged when the vessels are loaded, sticking a dozen feet out of the water."
