Atmos Capital Partners

Catastrophe bond specialists

A different source of return. A clear view of risk.

Catastrophe bonds pay investors a premium for carrying natural-catastrophe risk. Historically, their returns have shown low correlation with equity and bond markets. The predominant underlying risk is a large natural catastrophe.

01 / About Atmos

One asset class. Our own view of risk.

Atmos Capital Partners is a partner-led firm based in Zürich, dedicated to catastrophe bonds and independent of any bank, insurer or broker.

Catastrophe bonds

Securities that transfer natural-catastrophe risk from insurers, reinsurers and other sponsors to capital-market investors. They are our sole focus.

Risk assessment

Every bond gets a second view: we reassess its risk with licensed catastrophe models and our own judgement before investing.

Selectivity

Every position has to earn its place. We would rather pass on a bond than hold a risk we cannot explain.

02 / Our team

Complementary expertise. Shared conviction.

Our team brings together experience in insurance-linked securities, portfolio management, risk management, compliance, legal affairs and business management.

It does not constitute investment, legal or tax advice, an offer or a solicitation to buy or sell any financial instrument or financial service, or advertising for any specific financial instrument.

Risks. Catastrophe bonds are complex instruments with a high level of risk. A single natural catastrophe can lead to the partial or total loss of the capital invested, and market prices can also fall without such an event. Statements on this website about the characteristics of catastrophe bonds, including their correlation with other asset classes, are general, based on historical observations and not a forecast. Past characteristics and performance are not a reliable indicator of future results.

Products and documentation. Financial instruments and services, where available, are described exclusively in their legally required documentation, such as a prospectus and a key information document. Only that documentation is authoritative.

Accuracy and liability. The information on this website has been prepared with care but may change without notice. No warranty is given as to its accuracy, completeness or timeliness. To the extent permitted by law, Atmos Capital Partners AG accepts no liability for any loss arising from the use of this website or the information on it.
