What We Bring to the Securities Lending Industry          

Transparency and Price Discovery: When borrowers and lenders view and transact in an open and accessible market, the overall market quality tends to improve.  With AQS, operating procedures, fees, market data and algorithms are published in the interest of contributing to a trusted, reliable and open market center.

Access: The Essence of a Centralized Market: AQS provides equal access to an automated centralized market. Through a single point of contact for trading, access, clearing, settlement and post-transaction processing, AQS enables individual lenders and borrowers to trade in a common instrument in a common credit environment for the benefit of all market participants. Additionally, AQS operates on a world-class global exchange infrastructure to promote faster, automated execution and processing capabilities.  AQS members transact on a highly reliable trading platform through secure market access via AQS:GUI, AQS:API or an existing service provider. The AQS market has been designed to attract broad-based participation by lenders and borrowers to create alternative, stable pools of supply and demand.

Reduced Risk, Increased Confidence:  Central counterparties reduce traditional lending risks, including counterparty default risk, and provide guaranteed mark-to-market payments, mandatory corporate action settlements, and rebate rate payments.  AQS’s central counterparty, OCC, is the world’s largest equity derivatives clearing organization, and guarantees the counterparty creditworthiness of all lenders and borrowers.
