The odds on the U.S. Treasury's ultralongshot may just have narrowed.
Record-low interest rates make this an opportune time for the Treasury to revisit a proposal it's shelved in the past: To issue the longest-term debt it can. So for the second time since President Donald Trump took office, the department is exploring the prospect of selling bonds due in 50 or 100 years, going way beyond the current three-decade maximum.
The idea has fallen flat in the past, but now might be its moment. The world's spreading pile of negative-yielding securities — it's at $16.4 trillion and counting — is driving investors further out global yield curves, in part to finance retirees' longer lifespans. The rate on 30-year U.S. government debt fell to an all-time low sub-2% last week. It's now within about 60 basis points of what it would cost the Treasury to borrow for five years.
"The yield level for 30-year debt suggests there's still demand for duration and I don't think the Treasury expects that to change any time soon," said Thomas Simons, senior money-markets economist at Jefferies in New York.
The last time Treasury Secretary Steven Mnuchin broached the issue, in 2017, the dealer community snubbed it. Jefferies was among the more-receptive to the proposal then, too. But Simons said the prospects may be better now given the "significant pivots" of central banks toward lower rates and monetary easing.
And from the Treasury's perspective, the idea certainly seems timely as the department seeks to limit the cost to taxpayers of plugging a budget gap that's headed to $1 trillion annually.
"They might need an additional point on the curve to meet issuance needs," said NatWest Markets rates strategist John Briggs. While he sees the rationale for an ultralong bond, he said "there are no changes in the concerns I had in 2017."
Any such move is a long way off, according to Simons. But the Treasury is clearly keen to test the waters, posting a note on its refunding website at the end of last week that the Office of Debt Management is "conducting broad outreach to refresh its understanding of market appetite" for 50- or 100-year bonds.
