This paper traces the evolution of extreme illiquidity discounts among Treasury securities during the financial crisis; bonds fell more than six percent below more-liquid but otherwise identical notes. Using high-resolution data on market quality and trader identities and characteristics, we find that the discounts amplify through feedback loops, where cheaper, less-liquid securities flow to investors with longer horizons, thereby increasing their illiquidity and thus their appeal to these investors. The effect of the widened liquidity gap on transactions costs is further amplified by a surge in the price liquidity providers charged for access to their balance sheets in the crisis.

The risk of customers affects corporate financial policy by limiting the ability of firms to securitize customer receivables. We find that firms with riskier receivables, based on the credit risk and diversification of the firms' principal customers, have lower financing capacity and lower leverage in their asset-backed securitizations. Because securitizations are designed to create a very safe claim by separating the risk of the securitized assets from the risk of the originating firms, increases in the risk of the receivables directly inhibit originating firms' ability to securitize assets and indirectly inhibit the originating firms' access to external finance. The study highlights a novel link between the financing of supplier firms and the financial health of their customers and shows how an increase in risk can limit access to external capital.
