T-Bill Yields Plunging
Yields on the shortest term treasury debt collapsed towards zero last week:
As yields approach zero, this means that investors are willing to get almost nothing in return for holding government paper in the short term. In fact, according to a report from Reuters, 1- and 3-month T-bills actually went negative very briefly last week, meaning people were actually paying the government for the chance to lend it money.
