Last month's flooding in central Europe caused more than $16 billion in damage, about a quarter of it insured.
This made the incident the year's costliest natural disaster so far, a leading insurance company said today.
Natural disasters worldwide cost the insurance industry a total of about $13 billion in the three months from January to June, while the overall cost of disasters was some $45 billion, Munich Re AG said in a regular review of disaster costs.
Both figures were well below the average for the past decade.
Munich Re put insured losses from the flooding caused by the Elbe, Danube and several other rivers overflowing their banks at some $3.9 billion or more - most of them in Germany, but also in the Czech Republic, Austria, Slovakia and Hungary. That is a little higher than the $3.4 billion cost to insurers of floods that hit many of the same areas in 2002.
The overall cost of those floods, including uninsured damage, was $16.5 billion.
The German government has set up an €8 billion fund to pay for repairs. The flooding does not appear likely to throw the country's economy off course, since it did not hit major industrial areas.
"Politicians should not only set up emergency funds after catastrophes but should act with greater foresight, engaging in prudent supraregional flood control, which should ideally be coordinated across national borders," Munich Re board member Torsten Jeworrek said in a statement.
A series of tornadoes in Oklahoma - including the tornado that killed 24 people in Moore on May 20 - were the second-costliest disaster for insurers in the first six months of the year. They caused insured losses of nearly $1.6 billion, while overall losses totaled $3.1 billion, Munich Re said.
April's earthquake in China's Sichuan province caused $6.8 billion worth of damage but only a fraction of that - $25m - was insured, the company said.
Flooding last month in the Canadian province of Alberta caused damage initially estimated at more than $3 billion, with insured losses likely to top $1 billion.
For the whole of last year, Munich Re has said, natural disasters cost insurers $65 billion - with Superstorm Sandy in the US accounting for $25 billion. It put total disaster costs at $160 billion.
