Settlement risk has historically been a problem in foreign exchange markets
because each currency must be delivered in its home country. Due to time
zone differences, several hours might elapse between a payment being made in
one currency and the offsetting payment being made in another currency.
Continuous
Linked Settlement (CLS) is a
settlement system for foreign exchange trades that eliminates this
problem. The system is run by the CLS
Bank International, which is a special purpose bank dedicated to
settling foreign exchange trades. The bank and associated companies are
owned by (as of 2006) seventy-one of the world's largest financial
institutions, each of which owns an equal
share in an overall holding
company.
All transactions settle through the CLS Bank during a
single 5-hour window each business day. The CLS Bank is based in New York
but maintains accounts in the various countries whose currencies it
settles trades for. To settle a foreign exchange trade through the system,
a firm delivers the currency it owes to the CLS Bank. That payment is not
released to the counterparty unless that counterparty deposits the
offsetting payment for the transaction. Payments are
netted, so each participant in the
system only has to make one net payment per currency each day.
Direct participation is limited to the financial
institutions that are shareholders of the system. They are called
Settlement Members. User Members are institutions that are sponsored by
Settlement Members. They can submit settlement instructions for themselves
and their clients, but their transactions flow through the accounts of
their sponsoring Settlement Members. Other parties may not submit
settlement instructions directly to the CLS Bank, but they may indirectly
utilize the system as a client of a Settlement Member or User Member.
