Stablecoin issuers are rapidly becoming the most significant buyers of US T-bills, projected to drive $1 trillion in excess demand. Standard Chartered analysts warn this trend could fundamentally reshape US debt issuance over the next three years. The stablecoin market cap is expected to reach $2 trillion by 2028, generating fresh T-bill demand as issuers seek liquid reserves. While stablecoin growth stalled post-GENIUS Act, combined with Fed measures, total demand could swell to $2.2 trillion—far exceeding the $1.3 trillion new supply if Treasury maintains current debt ratios. Without intervention, T-bills could become 'too scarce' for the private sector.

Treasury Secretary Scott Bessent faces a unique opportunity. The $0.9 trillion in excess demand offers a tactical opening: increasing T-bill issuance share from 21.7% to offset shortages. This shift could effectively suspend all 30-year bond auctions for three years, dramatically flattening the yield curve. Standard Chartered notes this would represent a 'bull flattening' scenario, contrasting with their 2026 'bear steepening' base case. Bond investors must now monitor the rising influence of digital asset reserves.

This development forces Treasury to reconsider its debt strategy. By reallocating $0.9 trillion from bonds to bills, Bessent could stabilize the front end of the curve while mitigating scarcity risks. The move would likely accelerate curve flattening, with implications for long-term rates and investor positioning. Market participants are now watching how digital asset reserves will reshape Treasury's issuance priorities in the coming quarters.
