Wall Street Expects U.S. Short-Term Treasury Issuance of Approximately $1 Trillion
nashnova research
Three major banks forecast the U.S. will add roughly $1 trillion in net new T-bills over the next year, pushing short-debt share near pandemic highs — this means Washington's interest bill is growing more sensitive to every rate move.
How far apart are the three forecasts?
Bank of America projects $1.07 trillion in net new T-bills for fiscal 2027; JPMorgan sees $1.09 trillion for calendar 2027; Goldman Sachs is slightly lower at $961 billion.
Different time frames, same order of magnitude: roughly $1 trillion.
This means → the call is not one bank's outlier; it is Wall Street consensus on a short-debt surge.
Why does short-debt share matter?
Bank of America estimates outstanding T-bills will reach about $8 trillion by next September — 24.3% of total marketable Treasuries.
Goldman projects that share rising to 24.9% by 2028, near the pandemic-era peak.
In plain terms = the Treasury Borrowing Advisory Committee's comfort zone is around 20%. The current trajectory overshoots that by nearly five points. In the past two decades, the share briefly topped 25% only twice — during the 2008 crisis and during COVID.
What risk does heavier short-debt carry?
T-bills — government debt maturing within one year — must be continuously rolled over, and their yields track the Fed's policy rate closely. The one-year T-bill currently yields about 4.4%; the Fed funds rate sits at 3.75%-4%, with signals of further hikes.
This means → every rollover reprices at the latest rate. The higher rates go, the faster interest costs balloon.
BofA rates strategy head Mark Cabana says heavy T-bill issuance is creating "larger and more volatile" interest-expense risk. Maya MacGuineas, chair of the Committee for a Responsible Federal Budget, warns: "Heavy reliance on short-term debt leaves us highly exposed to rollover risk."
How does the government defend this?
Treasury officials point to a longer history: since 1970, T-bill issuance has averaged 24.3% of total issuance; as of last month, the actual share was 22.8% — below that long-run mean.
Joe LaVorgna, former Treasury economic adviser and now chief economist at SMBC Nikko Securities Americas, argues the rising share is "not a big deal." The absolute numbers look large mainly because the deficit itself is massive; in ratio terms, "it's not entirely out of control by historical standards."
In plain terms = the official logic is that the current ratio looks normal on a fifty-year scale. Critics counter that TBAC's target is around 20%, not the 1970s average.
Who is buying all these T-bills?
The Fed alone purchased $250 billion in T-bills in the first half of this year. This means → the net supply the open market must absorb is well below the banks' headline forecasts.
Money-market funds — holding roughly $8 trillion in assets — are a steady source of T-bill demand. Treasury Secretary Scott Bessent has also flagged stablecoins as a potential new buyer.
Some analysts expect, however, that Treasury's expanded long-bond buyback program — designed to cap long-end yields — will be funded by issuing more T-bills, creating a feedback loop: suppressing long rates by adding to short supply.
How long can this strategy hold?
The core tension: short-term debt is cheaper to issue (one-year at 4.4% vs. thirty-year at 5.3%), but it rolls over frequently and is highly rate-sensitive.
For now, the Fed and money-market funds provide a demand backstop; there is no sign of indigestion.
This means → whether T-bill share can keep climbing without triggering market disruption is the critical test of the current funding strategy — if demand falters or the Fed scales back purchases, rollover costs will surface fast.
