According to a study by Guy Carpenter & Company, LLC, released earlier this month, reinsurance rates for most lines of property insurance decreased at the Jan. 1, 2010 renewal, compared with rates for similar coverage in 2009. Guy Carpenter’s “Rates Retreat as Capital Rebounds: Global Reinsurance Renewals at Jan. 1, 2010″ can be found here. Guy Carpenter attributes the rate decrease to a variety of factors, including relatively low catastrophe losses during 2009, the lingering effects of the recession on demand, and a rally in global financial markets, all of which lead to an excess in supply and increased competition. It remains to be seen whether this declining trend will continue through 2010. Guy Carpenter notes some “longer-term clouds on the horizon” that may temper the current competitive conditions over the next months, leading to rate increases.
