The LA Times writes "Treasury bond yields dive again; some T-bill buyers said to take less than zero". It says, "Shorter-term yields also slid. Heavy demand for three-month Treasury bills -- considered the ultimate safe parking place -- drove their annualized yield to a mere 0.008% from 0.015% on Wednesday. Some trading services said T-bill yields actually went negative for a time, meaning investors would in effect be paying the government to hold their money. The latest slide in T-bill yields may reflect decisions by U.S. money market mutual funds to cash out some of the short-term European bank debt they own and bring the money home, as investors focus on potential risks stemming from the ongoing European government-debt crisis."
