Significant weather event losses in the United States have so far been dominated by thunderstorm, wildfire and tornado activity. The severe weather activity topped the list, incurring $8.8 billion of the half-year's total of $9.3 billion dollars in insured losses, a sum that still pales in comparison to the $24.4 billion seen in the first half of 2011.

The winter of 2012 claimed few losses, but low levels of spring flooding gave way to exacerbated drought during the warmest summer on record since scoring began at the turn of the last century. The U.S. drought monitor has reported record-setting conditions, said Munich Re, and wildfires have burned 1.7 million acres, mostly attributed to the Waldo Canyon fire, the most damaging in Colorado state history.

This year's early tornado season, a probable result of the warm winter, produced a severe squall line that crossed several Midwestern states between March 2 and 4, slamming into 180,000 buildings and generating $2.4 billion in insured losses in the Ohio and Tennessee River Valley, as well as an outbreak in the St. Louis metro region causing 200,000 claims and $1 billion in losses.

What we haven't seen yet is the worst of the hurricane season. Unusually, two tropical storms occurred before the official June start of the 2012 Atlantic season, causing $50 million in damages. Otherwise there has been little to report on this front, says Munich Re spokesperson Thomas Reinhart during a conference call today. He added that this could change when the season peaks in August and September.

During the call, Ernest Rauch, head of Munich Re's corporate climate center, says worldwide losses of $26 billion were spread over 450 significant loss events, the most major of which were an Eastern European cold wave claiming 745 lives; a winter avalanche in Afghanistan; Winter Storm Andrea and the earthquake in Italy.

The level was still below the six-month average of the past decade, he says. Insured losses amounted to $12 billion, compared with ten year average of $19.2 billion—and lower losses have been contributing to better profits, he adds.

“Barring any future mega-catastrophes, 2012 will eclipse 2011 profits by a significant margin, and may achieve its best levels yet in a post-crisis era,” says Robert Hartwig, president of the International Insurance Institute, during the call, attributing the surge in combined ratio in 2011 to catastrophe losses, and their decrease in 2012 to the year's reduction in combined ratio.

“In 2011, homeowner insurers paid out $1.24 for every $1 they earned in premiums, and suffered losses totaling $36.5 billion, but these losses evened out in the first half of this year,” says Hartwig.
