SSF Engagement Initiatives

Open letter to index providers on controversial weapons exclusions

SSF coordinates an investor initiative for an "Open letter to global index providers" to exclude controversial weapons* from mainstream indices.

Detailed description

A number of international conventions prohibit or restrict the development, production and use of controversial weapons. Some countries have gone further by implementing legislation against direct and/or indirect financing of such weapons. For institutional and individual investors, excluding companies involved in controversial weapons has become standard practice or expectation. However, mainstream indices continue to include such companies. This is causing a problem for active and passive investors who may be subject to extra tracking error and/or additional costs, or unable to invest in controversial weapons-free solutions.

Swiss investors therefore have launched this investor initiative and SSF is coordinating the collection of co-signatories who support the view that index providers should remove companies involved in controversial weapons from mainstream indices.

Launched in August 2018, this initiative has already received the support from a core group of more than 60 Swiss investors representing over USD 2 trillion. To co-sign this letter, please fill in the signatory form.

Latest figures (as of 12 December 2018)

  • 89 signatories
  • USD 4.6 trillion

The letter is on Swiss Sustainable Finance (SSF) letterhead, as SSF holds the coordination role of the letter and subsequent actions, and will be signed by institutions only (i.e. no names of individuals).

The call for signatories will remain open until 21 December 2018, after which time we will inform you about further steps.


The call for signatories is also posted on the PRI Collaboration Platform where PRI signatories can find further information.
