GSE securities are issued by government sponsored entities. Moneyline Telerate, which is currently the only market data firm contracted to distribute TradeWeb data, says the initiative is consistent with the Bond Market Association's pending recommended voluntary practice guidelines for secondary market trading in certain GSE European-style callable securities (ECS). The data will consist of TradeWeb's benchmark agency yield curves as designated by the respective agencies and will be delivered on a real-time feed from MoneyLine Telerate to any company.
