zoom The increasing number of large marine losses can potentially put severe financial strain and overwhelm insurance companies, Dieter Berg, President of the International Union of Marine Insurance (IUMI), said during the closing of this year’s IUMI 2016 marine insurance conference in Genova, Italy.Berg cited the recent losses connected with the Chilean earthquake in 2010, the Japanese earthquake and tsunami in 2011 (USD 3.8 billion loss), Thai floods in 2011 (USD 2.5 billion loss), Hurricane Sandy in 2012 (USD 3 billion loss) and the Tianjin explosion in 2015 (USD 3-4 billion loss expected).These marine losses were often coupled with associated major property losses, Berg said.“Our industry is concerned that natural catastrophes, due to climate change, are occurring more often and with greater severity,” Berg said.”Coupled with this, globalisation and the unrelenting growth of global trade is driving an increase in the value of goods being transported by sea and an increase in the quantity of goods being stored on ultra-large container ships, or in port terminals. These have the potential to create extremely large losses. Recent marine losses have been very expensive for insurers and often an accumulation of multiple business lines occur which can include cargo losses, container losses, warehouse damage, destruction of automobiles, damage to pleasure craft and even fine art losses. At Tianjin, for example, around 68,000 cars were affected, i.e. a total loss or damaged, by a single explosion.”Berg explained that when large marine losses were combined with property and other losses, there was a real concern that this might overwhelm insurance companies.He called on the industry to understand, clearly, their aggregate positions and to manage their exposures by carefully modelling their risk positions.
