Asset-Backed Commercial Paper (ABCP) Run
The Formal Definition
A systemic liquidity crisis where institutional investors refuse to roll over short-term commercial paper debt issued by conduits holding long-term, illiquid securitized assets, forcing sudden fire-sale liquidations or sponsor bank bailouts.
Refinancing Shortfall = Maturing Commercial Paper Principal - Uncommitted Conduit Liquidity Lines (When Short-Term Rollover Demand = 0)
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Commercial paper is how major corporations borrow money for 30 or 90 days to fund payroll. In an ABCP conduit, financial engineers put 30-year mortgages inside an entity and funded them by issuing 30-day paper to money market funds. When investors smelled toxic debt in 2007, they refused to roll the paper. The short-term cash vanished, leaving conduits with long-term debts they could not pay."

Examining the real numbers for: Institutional treasury fund managing $10,000,000 in short-term liquidity during a banking credit crunch
| Execution Metric | Pure Treasury Bill Allocation (Sovereign Collateral) | Yield-Chasing ABCP Conduit Investor |
|---|---|---|
| Fee / Rate | $0.00 | Standard institutional custody |
| Spread / Buffer | Invested strictly in 4-Week US Government T-Bills | Chased an extra 45 basis points in yield by buying bank-sponsored ABCP notes |
| Execution / Status | Rollover demand backed by the full faith and credit of the sovereign issuer | Investors refused to roll the conduit's maturing paper; fund froze redemptions |
| Total Cost / Result | Zero exposure to commercial credit freezing | Suffered illiquidity lockup and capital write-downs chasing fractional yield |
How Brokers Weaponize This Term
Money market funds and corporate sweep accounts historically marketed prime and ABCP-backed yields as 'cash equivalents', obscuring that rolling short-term debt backed by illiquid collateral carries catastrophic run risk.

What happens when a money market fund 'breaks the buck'?
It means the fund's Net Asset Value (NAV) falls below the fixed $1.00 per share baseline due to credit losses in its commercial paper or debt holdings.
What role did ABCP play in the 2008 Financial Crisis?
Conduits funded subprime mortgage-backed securities with short-term ABCP; when the paper could not be rolled in late 2007, sponsor banks had to absorb hundreds of billions in toxic assets.
