Major supply chain insurance is in greater demand as more companies seek to protect their assets from non-physical damage.
Companies have increasingly complex supply chains and need greater protection against things like the volcanic ash cloud and industrial action, it is claimed.
Risk and insurance expert Marsh has seen more businesses that depend on air for transporting materials, products and goods to customers worried about airspace restrictions.
The firm said traditional property damage and business interruption do not cover these losses and will not pay out unless actual damage is incurred.
Caroline Woolley, from Marsh, said: "We have seen a significant increase in interest for specialist non-physical damage supply chain insurance, such as those Marsh has created with leading insurers.
"Supply chain insurance would provide cover for some of the business interruption losses suffered by companies when the volcanic ash cloud disrupted their supply chain."
