Sort of amazing that investors are will to take zero interest for a safe place to park cash: 30 day TBills...

From Wednesday's WSJ, excerpted:
"Investors gave the U.S. government 0% financing and the yield on other Treasury bills fell below 0% on
Tuesday...

The Treasury sold four-week notes at a 0% yield for the first time, with investors in effect giving their
cash to the government for safe-keeping until 2009. This rush to safety occurred last year, too, when
investors wanted only to own the very safest, most liquid investments when they closed their books at
the end of the year."

The same nervous investors snapped up three-month Treasury bills, pushing their prices up and yield
down below zero for a brief period."
