US Treasury to Ramp Up Q3 Borrowing by 82%, with Major Short-Term Bond Issuance

TradingKey - On Monday, July 28, the US Treasury announced that it expects to borrow $1.3 trillion in net marketable debt for the third quarter, a sharp increase from the previously projected $554 billion in April—an 82% jump. This borrowing is necessary to cover maturing debts and replenish depleted cash reserves.

Cash Reserves Depleted

The increased borrowing projection is attributed to low cash reserves at the start of July and anticipated weak cash flows in the coming months.

After the US government hit its $36 trillion debt ceiling earlier this year, the Treasury reduced bond issuance to avoid default, depleting cash reserves to meet its obligations. 

The recent Big Beautiful Bill Act, raising the debt ceiling by $5 trillion, temporarily averted a debt crisis. Consequently, the government plans to expand borrowing and accelerate debt issuance to rebuild the Treasury General Account (TGA), targeting an $850 billion reserve by the end of September.

Preference for Short-Term Bonds

Treasury Secretary Besent noted in June that long-term debt issuance would only be considered viable if interest rates fell, as high yields make it less attractive.

President Trump has advocated issuing short-term Treasury bills, maturing in 6-9 months, and shifting to long-term debt post-Powell's term when rates might decrease. Short-term borrowing is more cost-effective, avoiding the premiums demanded by long-term bond investors. Therefore, the market expects the Treasury to stabilize long-term bond issuance while increasing short-term bill sales.

Tepid Demand at US Debt Auctions Amid Fiscal Challenges

BlackRock's analysis highlights concerns about the market's capacity to absorb increasing US debt supply. Despite potential Federal Reserve rate cuts, bond yields might continue to rise due to oversupply, thereby increasing borrowing costs and fiscal pressure. The declining foreign demand for US debt raises the risk of insufficient buyers. 

Ray Dalio of Bridgewater Associates warned that sustaining debt through new issuance and Fed rate cuts is unsustainable, potentially triggering market panic and financial instability. 

On Monday, the Treasury's $70 billion 5-year note auction saw weak demand, with a high yield of 3.983%, 0.8 basis points above pre-auction levels—the largest tail since last October.

The Treasury is set to announce its medium- and long-term debt issuance plans on Wednesday, expected to significantly impact bond market trends and draw substantial market attention.
