300 billion dollars of residual value sits off the coupon stack

The debt sits in the vehicle, the promise on the guarantor

Over the past year technology companies issued up to 300 billion dollars of residual-value guarantees tied to data centres and chips. Investors lend to a special-purpose vehicle; if the facility or chips later sell below an agreed value, the guarantor covers part of the shortfall. Meta supported about 27 billion dollars of Hyperion project debt in Louisiana with a roughly 28 billion dollar guarantee; Broadcom took on about 29 billion dollars around chips destined for Anthropic; Nvidia provided 105 billion dollars of guarantees tied to a SoftBank data-centre development for OpenAI.^[1]

Because the debt sits primarily in that vehicle, much of the exposure does not initially appear as ordinary debt. If residual values fall below the guaranteed floor, losses that were not sitting on the headline balance sheet become a cash claim on the guarantor. Credit-rating agencies examine those guarantees even when accounting keeps them away from headline liabilities. The fault line is a guaranteed floor that turns into a cash call.^[1]

A cheap coupon shows a different door

The 19 September column tied CoreWeave's 2.875 per cent coupon on 3.7 billion dollars of convertibles, together with maturity and the unsecured stack, to the share. That door still stands: the lowest-rated borrower's coupon ties a sale to the equity price. Up to 300 billion dollars of residual-value guarantees move the same spending wave through a different door. The guarantor pays if asset values print below the floor. The two doors share a shock and stand on separate balance sheets.^{[1], [3]}

Short tenor is another rollover wall

The same day, Wall Street expects the United States to raise about 1 trillion dollars of net funding through short-term Treasury bills. Bank of America sees 1.07 trillion dollars in the fiscal year to September 2027 excluding refinancing of maturing debt, JPMorgan 1.09 trillion dollars in 2027 and Goldman Sachs 961 billion dollars; outstanding bills may reach about 8 trillion dollars by next September, or 24.3 per cent of marketable paper, against a Treasury Borrowing Advisory Committee guide near 20 per cent. Mark Cabana said heavy short-term issuance could make interest expenses larger and more volatile. The shared constraint is shorter tenor: the technology guarantor rolls residual value, short-term bill supply rolls. If residual-value guarantees become a cash call, or a rating agency consolidates a larger share of the 300 billion dollars as on-credit, guarantor exposure moves toward headline debt.^{[1], [2]}
