Natural catastrophes quite often prove the most costly in terms of insured P&C losses, including a wide spectrum of triggers from auto and property damage to business interruption and even supply chain losses.

Insured losses were roughly $45 billion U.S., down from $81 billion in 2012 and below the inflation-adjusted average of $61 billion for the previous 10 years, due largely to a benign hurricane season in the U.S., says Swiss Re in its latest Sigma report on natural catastrophes in 2013.

In 2013 almost 26,000 people lost their lives or went missing due to natural catastrophes and man-made disasters, making the year the 20th most deadly on Sigma records. The number of lives lost was up 83% from the previous year but was well below the yearly average since 1990 of around 68,000 deaths.

Globally, about 20,000 people were killed or went missing in natural disasters in 2013, the majority in storms, floods and other severe-weather events.

Date: 11/8/2013

Insured Losses: $1.5B

Economic Losses: $12.5B

Country/Countries Affected: Philippines, et al

The deadliest disaster event in the history of the Philippines, Typhoon Haiyan caused the greatest amount of deaths in 2013, with around 7,500 people killed or declared missing in the Philippines, Vietnam and China.

In terms of economic loss, the biggest loss-inducing event was Haiyan, the Category 5 strength super typhoon that made multiple landfalls in central Philippines with record wind speeds and was the largest humanitarian catastrophe of the year globally and one of the strongest typhoons to have ever been recorded worldwide.

Haiyan triggered coastal storm surges with subsequent flooding and mudslides that wiped out entire coastal towns such as Tacloban, where the water level was estimated to have risen to 6.5m.

The Philippine authorities provisionally estimate the property, agriculture and infrastructure damage from Typhoon Haiyan to be at least $12 billion. Insured losses are estimated to be $1.5 billion, including losses from public-infrastructure cover.
