The report outlines results from the “Business Continuity Institute's 2012 Supply Chain Resilience Survey,” which show that unplanned outage of IT/telecoms was the most significant cause of supply-chain disruption last year, outpacing adverse weather, which placed second.

Outsource service provider failure was the third most significant cause of supply-chain disruption. Guy Carpenter summed up this risk by noting that a disruption at a technology company in a distant land rendering cloud-based services to a company in Wisconsin could ripple out into a series of events that leaves the Wisconsin company without access to a key part of its infrastructure.

The disruption could be something as simple as a local interruption to the power supply, Guy Carpenter said. “No longer is there necessarily a direct physical or even indirect physical connection between the holder of a company's data and the company,” the report points out.

Further down the list of 2012 supply-chain disruptions, cyber attacks now outstrip fire and social unrest, according to Guy Carpenter. The report notes that cyber attacks in general are on the rise, with 2012 breaking the record with respect to the number of reported data-loss incidents.

“With 2,644 incidents recorded [for 2012] through mid-January 2013, 2012 more than doubled the previous highest year on record (2011),” Guy Carpenter said. “Furthermore, the extent of attacks is likely to be far higher since around 20% of reported incidents did not disclose the number of records involved.”

Taken together, Guy Carpenter said technology risk factors—unplanned outage of IT/telecoms, outsource service provider failure and cyber attacks— make up the majority of all supply-chain disruptions in 2012.

As for covering these risks, the global consultancy said the insurance industry is aware that companies are more exposed to external risks than ever before. Technology allows business to be conducted all over the world instantaneously, but that also means supply-chain failures can significantly impact a company's revenue and reputation.

Insurers and reinsurers therefore are demanding that companies improve their supply chain risk-management strategies before business interruption/contingent business interruption coverage is offered.

Guy Carpenter said companies have a responsibility to review suppliers' business-continuity plans and gain a better understanding of their supply chains, “identifying and anticipating potential problems and taking measures to prevent them from causing significant disruption.”

Companies that do this will be able to take advantage of the broadest and best BI/CBI coverage in the marketplace, the consultancy's report said.
