问题如下：
Many FMUs have developed innovative ways to
clear and settle transactions that reduce the overall operating liquidity
required by the system (i.e., liquidity savings mechanism). About the liquidity
savings mechanism, which of the following is NOT correct?
选项：
A. These tactics essentially
increase transaction throughput for a given amount of liquidity by reducing the
size of settlement positions (and settlement risk) and minimizing the cost of
idle liquidity for a participant.
Examples of liquidity savings mechanisms include
transaction netting (bilateral and multilateral)
FMUs use transaction throughput requirements (e.g.,
requiring a certain percentage of outgoing transactions to be submitted by a
mid-day deadline) to achieve liquidity savings mechanisms.
In a deteriorating credit situation, an FMU may begin to monitor a participant’s risk position and its initial and variation margin collateral values in real-time to ensure sufficient coverage.
