在一篇讲英国现金管理的文章中有如下文字：

The Chancellor decided to transfer Exchequer cash management responsibilities to the Treasury as part of the new monetary policy arrangements to clarify the roles of the Bank and the Treasury and to avoid any perception of conflicts of interest in market operations. Another benefit of this approach is that the management of the short- and long-term government borrowing programmes can be fully integrated.

请问文中的“ Exchequer”与“Treasury”是英国的什么部门？怎么翻译？多谢多谢！
