Manage risks...

Core to what we do is managing the risks you face using bespoke strategies tailored to your needs


... without sacrificing returns

Not earning return is also a significant risk. All of our strategies aim to manage risks without compromising on your return objectives.

What we offer

Clients can access our derivatives strategies through two offerings.

Liability-driven investments

Using a tailored approach to each client, we help clients reduce the risks they face in relation to changes in the value of their liabilities. This is particularly pertinent as funds have to make payouts in the future.

Generally, our strategy involves the use of interest rate and inflation swaps, supported by collateral management. Our combination of deep specialist expertise in liability management, with our size, makes us more nimble in responding to changes in the market and more responsive to your needs.

Structured equity

This allows pensions and other funds to shape their exposure to the markets, by targeting the return they need, while offering the necessary protection from falling markets. Our experienced team helps each client create tailored exposure to equity markets, through the use of equity options, as well as bonds and gilts.

Generally, this helps to reduce downside risk exposure by forfeiting a portion of returns for protection when markets fall.
