Here's One Way to Get Buyers for Treasury Securities...

Force money market mutual funds to buy them.

NYT's Joe Nocrea writes:

The Securities and Exchange Commission, meanwhile, is proposing new rules for money market funds: stricter limits on the kinds of securities they can hold, for instance, and new liquidity requirements. There is even talk of a “liquidity facility” to help the industry though another crisis of the list for safety

You just know that a top rank for safety is going to go to Treasury securities. There will be some type of risk index, which will result in every money market mutual fund buying certain amounts of Treasury securities to meet the risk index requirements.

In the column, Nocrea actually proposes the correct solution. Let the markets take care of money markets and let the funds trade around par, but not necessarily at par.
