Western and West Asian insurance specialists see Iran as an appealing $8 billion market in the wake of its nuclear deal with world powers, though uncertainty over when sanctions on Tehran will be lifted means they are treating the country with caution.

Eight out of 11 insurance and reinsurance specialists who responded to questions emailed by Reuters this week said Iran was an attractive or very attractive market, especially in the marine and energy sectors.

Responses were on an anonymous basis due to the sensitivity of the issue.

While several said they expected to have entered the Iranian market by the end of 2016, others said it was hard to say due to ongoing concerns about how and when sanctions might be repealed.

Under the accord reached in Vienna on July 14, Iran will be subject to longer-term curbs on its nuclear programme in return for the removal of US, UN and European Union sanctions.
