Lloyd's is to stress test the ability of the market to withstand a major terrorist attack on planes and airports.

The realistic disaster scenarios will assess whether Lloyd's insurers are capable of withstanding insurance losses from strikes on up to five airports along with damage to 15 passenger planes.

The first exercise, to be developed around an aviation-related attack, will test whether syndicates have enough reinsurance cover to pay out for the loss of lives, damage to buildings and aircraft and potential business interruption.

Rolf Tolle, franchise performance director at Lloyd's, said: "Recent events highlight the continuing interest in aviation interests as targets for terrorism. This interim realistic disaster scenario exercise is designed to give Lloyd's insight into the likely loss implications for individual syndicates and the market as a whole, to a number of specified terrorist attacks."
