Can I cash my $450?

According the Nikkei, "Japan's most authoritative and influential business news publisher" (Isn't it more straightforward to just say "Japan's WSJ"):

WASHINGTON (Nikkei)--China has outstripped Japan as the top holder of U.S. Treasury securities, according to data released Tuesday by the U.S. Treasury Department.

China is holding America's T-Notes in the amount of 585 billion US Dollars.

585/1.3=450.

I mean, CAN I CASH MY $450? With that money I can get lots of good food to pull me through the finals, and a beautiful floor lamp so that I can stay in my cozy little room.

Knock on wood.
