LTD Acceptable Securities

LCH Ltd accepts a wide range of debt securities issued by high quality sovereign government issuers and certain government agencies to meet initial margin obligations.

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

The above link refers to securities collateral acceptable to LCH Ltd as initial margin cover for business cleared. Certain European regulators have agreed that OTC instruments registered with LCH Ltd should be exempt (following Directive 2000/12/EC of 20 March 2000) from credit equivalent amount add-on. Any such exemption applies to LCH Ltd Clearing Members only where initial margin requirements are met with cash or Government Securities acceptable by LCH Ltd. Clearing Members are responsible for ensuring that they comply fully with all regulatory requirements.

Securities collateral - Essential Details

Whenever securities are transferred to LCH Ltd, these securities are held by LCH Ltd under the terms of a deed of charge between LCH Ltd and the respective Clearing Member or client.

As such, before any securities are accepted, the Clearing Member (or client) must have executed the deed of charge.

In addition to the legal form of charge, where client securities are to be delivered to LCH Ltd under a form of charge, a Client Consent is also required (with the exception of SwapClear Clearing Members).

To facilitate margin delivery, Clearing Members may lodge securities either directly with LCH or using a tri-party arrangement. All Clearing Member proposals for the lodgement, release or substitution of securities must be submitted through the Collateral Management System (CMS).

Certain taxation restrictions and requirements may apply to securities including, but not limited to:

i. Before pledging Spanish Government securities, Clearing Members will be required to provide LCH with details of their tax status, in accordance with Spanish tax law

ii. Before pledging Italian Government securities, Clearing Members will be required to complete a Tax Exemption Application Form, which can be obtained from LCH  

iii. Before pledging US Government securities, Clearing Members will be required to provide LCH with details of their tax status, in accordance with US tax law


You can find the Client Consent form here.


Government Agency securities collateral is subject to a minimum nominal size and sufficient market quotes. Set by Clearing Member, concentration limits are the lower of 20% of the margin requirement or 500 million - USD for US agencies; or EUR for European agencies with separate limits applied to GNMA MBS securities. A 10% limit of the total amount outstanding on any Agency ISIN will also be applied at a Clearing Member level. Acceptable issues will be maintained using ISIN lists.

LCH Limited acceptable securities are also eligible for FCM collateral purposes and will be subject to all other constraints applicable to margin collateral more generally.

Triparty Collateral Management

At LCH we are great supporters of triparty collateral services and the benefits that they can provide for our Clearing Members.

Triparty collateral management allows you to post non-cash collateral to LCH Ltd to cover initial margin requirements in a more efficient way than pledging bonds bilaterally, which can be operationally burdensome and inefficient.

Triparty services provide a more streamlined process. They’re automated, facilitating the delivery of non-cash collateral to LCH to meet your initial margin obligations on your behalf without requiring you to specify the specific securities you wish to post.

The utilisation of triparty agents among our membership is growing, with around 20% of LCH’s non-cash collateral delivered to the clearing house through triparty services.

More automation and more efficiency – what’s not to like?
