Treasury may let investors pay to lend to U.S. government
(Reuters) - The U.S. government may ask investors to pay for the privilege and safety of holding short-term debt issued by its Treasury Department.
In response to clamor from investors, the Treasury said on Wednesday it was looking closely at allowing negative-yield auctions. This would mean bidders who want the security of U.S. government debt in the face of global insecurity, might have to pay a premium for it. Doing so would allow the U.S. government to benefit from something that is already occurring on the secondary market, where investors have accepted negative yields in recent months to protect their cash from financial strains.
