Which one of the following statements about multilateral netting systems is not accurate?
选项：
A. Systemic
risks can actually increase because they concentrate risks on the central
counterparty, the failure of which exposes all participants to risk.
B. The
concentration of risks on the central counterparty eliminates risk because of
the high quality of the central counterparty.
C. By
altering settlement costs and credit exposures, multilateral netting systems
for foreign exchange contracts could alter the structure of credit relations
and affect competition in the foreign exchange markets.
D. In
payment netting systems, participants with net debit positions will be
obligated to make a net settlement payment to the central counterparty that, in
turn, is obligated to pay those participants with net credit positions.
解释：
ANSWER: B
Answers C and D are both correct. Answers A and B are contradictory. A multilateral netting system concentrates the credit risk into one institution. This could potentially create much damage if this institution fails.
