Han, Song and Nikolaou, Kleopatra, Trading Relationships in the OTC Market for Secured Claims: Evidence from Triparty Repos (May 27, 2016). Available for download at SSRN: http://ssrn.com/abstract=2785586

“We use a new panel data set on intraday transactions of triparty repos (TPR) to study trading relationships in the over-the-counter market. We test the prediction that search frictions lead to relationship formation. We find that TPR trading parties form relationships with a broad number of counterparties but tend to focus their transaction volumes on only a small set of counterparties. We also find that having stable relationships and broader interactions across other funding markets positively shapes the relationships of investors with dealers in the TPR market. Finally, our results suggest that relationships affect the likelihood of a trade and terms of trade and help buffer demand and supply shocks to liquidity. Specifically, the Fed’s Reverse Repurchase (RRP) exercise draws funds away from lenders in the TPR market, effectively generating a negative shock to the supply of funds for dealers. Meanwhile, Treasury auctions introduce a positive shock to the demand for funds by dealers. We find that in both cases, shocks are absorbed better by trade partners with stronger relationships.”
