How does Continuous Linked Settlement Work?

What is Continuous Linked Settlement (CLS)?

Continuous Linked Settlement System was introduced to provide settlement services for forex transactions to its participants/members to mitigate settlement risk and help financial markets remain relatively unscathed from systemic risks. CLS helps in the mitigation of risks, does not eliminate them.

Motivations behind the establishment of CLS and its working methodology:

Continuous Linked Settlement was introduced in 2002 post fallout on the potential default of financial liabilities to be honored in forex transactions (German Bank). Forex markets have volumes worth trillions of dollars and the trades represent multi-currency trades with exposure worth much more than real capital. Such trades have to be settled on a regular settlement day.  Foreign exchange transactions take place during multiple time zones and the exchange of currencies doesn’t happen concurrently exposing both parties and financial institutions to potential liquidity, credit, settlement, and systematic risks.

Let’s examine how the introduction of CLS helps forex markets. There’s a party that sold the currency before it received the proceeds from the counterparty. If the counterparty couldn’t honor obligations, the seller party could likely face default risks. CLS helps in mitigating settlement risks by simultaneously transferring funds by the Payment Versus Payment method while keeping liquidity requirements to a reasonable threshold.

Involved parties in forex transactions transfer the amount to CLS and CLS settles both trades simultaneously. When such large amounts are settled, they involve sacrificing huge liquidity in turn affecting daily turnovers as well. CLS comes as a savior in two ways- it helps in gross settlement(acts as an agent)-mitigating settlement risks and only netting of balances of aggregate long/short positions are required to be paid out to parties which reduces liquidity requirements drastically.

CLS settles all transactions during 5 hours window through RTGS when all currency jurisdictions are open. Participant member countries are required to hold multi-currency accounts with CLS for convenient transactional settlements.

How Foreign Exchange Transactions take place?

Here, Bank A sells Japanese Yen (JPY) to Bank B in exchange for US Dollars (USD) & trades are settled on normal settlement day. Bank A sells JPY & sends instructions to its correspondent bank Ja to send JPY to Bank B’s correspondent bank JB. Bank Ja executes the transaction by debiting Bank A’s account on relevant settlement day & sending Yen to Bank Jb. Bank Jb credits Yen to Bank B’s account & informs Bank B of the arrival of JPY.

In a similar fashion, Bank B instructs its correspondent Bank Ub to send USD to Bank A’s correspondent Bank Ua. Bank Ua credits USD to Bank A & informs the Bank A of the arrival of USD.
