COSI (Collateral Secured Instrument)

COSI stands for Collateral Secured Instrument and refers to structured products where the issuer deposits collateral covering its obligation to the holder, held in custody at SIX Swiss Exchange. In the event of the issuer's insolvency, this collateral may be realised, which reduces but does not fully eliminate the risk of loss.

02

The collateral buffer may vary depending on market conditions; a residual risk remains with the holder.

03

COSI is a collateral system administered by SIX Swiss Exchange, specific to the Swiss market.

Frequently asked questions

COSI products provide a degree of protection against issuer insolvency through deposited collateral. This protection is not complete, however: realisation costs, timing, and the value of the collateral at the point of insolvency can mean that a portion of capital is lost. COSI products are therefore more secure than unsecured certificates, but are not a risk-free investment.
