SA Acceptable Securities

At LCH SA, Clearing Members and their clients are able to post debt securities issued by high quality sovereign government issuers and certain government agencies to meet initial margin obligations.

LCH SA accepts three forms of non-cash margin:

  1. Securities collateral: deposited via Full Title Transfer Accounts opened by LCH in various Central Securities Depositories (CSDs)

  2. Central Bank Guarantee offers provided by the National Belgium Bank (NBB) or Dutch National Bank (DNB)

  3. Pledge Solution: enables CDSClear and RepoClear members to enter into a collateral arrangement whereby it deposits eligible collateral via a Single Pledgor Pledged Account (SPPA) opened by LCH SA in Euroclear Bank


Securities Collateral Haircuts

All securities posted as collateral are subject to “haircuts”. The size of the haircut is influenced by the tenor of the bond pledged. Haircuts are typically smaller for bonds with shorter maturities and higher for securities with longer tenors.
