We make the case for the U.S. government to issue a new security with a coupon tied to the United States’ current dollar GDP. This security might pay, for example, a coupon of one-trillionth of the GDP, and we propose the name “Trill” be used to refer to this new security. This new debt instrument should be of great interest to the Government for its stabilizing influence on the budget (as coupon payments fall in a recession with declining tax revenues) and for its yield, based on our valuation. Standard asset pricing analysis also suggests that Trills would enable important new portfolio diversiﬁcation strategies and, in contrast to available assets that protect relative standards of living in retirement, Trills would have virtually no counterparty risk. We believe there would be a lively appetite for the Trill from institutional investors, public and private pension funds, as well as the individual investor.
