When failure is an option: Fragile liquidity in over-the-counter markets

Markets can give false impressions of liquidity and stability if failed attempts to trade are ignored. For collateralized loan obligations, we quantify this bias by estimating the total cost of immediacy (TCI) which incorporates failure rates and failure costs. TCI is substantially higher than the observed cost, 0.3–3.8% versus 0.04–0.12% across credit-quality tranches because trade failures are frequent, failure costs are large, and failure costs and rates are correlated. TCI is almost double the realized gains from trade for low-rated tranches. Overall, auction-based over-the-counter markets become illiquid and fragile, especially during stressful periods for low-rated assets.
