This is troubling

This concerns me -
It has been mentioned that the Government - Treasury and the Fed - have begun to monetize the national debt. First sale was today and drew a less than enthusiastic turnout (oh, also today - In Great Britain, a routine sale of Government bonds today fell short. The Treasury failed to find buyers for £120million worth of debt.
It was the first time since 2002 that the Government has been unable to sell its debt, and this will be seized on by those who have warned that there is insufficient demand for the volume of debt being sold by the Treasury.

The central bank cut its main rate to almost zero in December and switched its focus to emergency credit programs.
On the power to sell debt, “I would feel happier having it now” so the Fed could use that authority to adjust its balance sheet, Yellen told reporters yesterday after a New York speech. Even without that tool, “there is a great deal we can do,” she said, “but it would certainly be a nice thing to have.” “
