注意到这是Economist 上面的一篇文章中的一段,试着翻译如下：
目前最大的市场是抵押物管理：帮助金融机构和公司管理人们欠他们的抵押物,或是监管机构要他们公示的、在与中央对手方（CCP）进行衍生交易（所形成）的抵押物.
两个that都是修饰the collateral,作定语.that regulators want them to post with central counterparties on their derivative transactions.that定语从句那 central counterparties on their derivative transactions这一部分算什么？that regulators want them to post with central counterparties on their derivative transactions.第二个that也是指前面的collateral, regulators want them to post with CCP......就是监管机构要求他们与中央对手方一起将他们在衍生交易中所获得的collateral进行公示。这个them是指前面的financial institutions and companies，on their derivative transactions: 在他们衍生交易过程中。
