US commercial property and casualty rates fell 3% last month after dropping 2% in October, according to analyst MarketScout.

“There are very few signs of rate increases,” CEO Richard Kerr said.

Commercial motor and property were the only two lines to rise, with rates up 2% and 1% respectively. All other lines were flat.

By account size, rates were flat for all except “jumbo” accounts of more than $US1 million ($1.36 million), which fell 3%.

Personal lines rates were down 1%, the first decline in almost four years, as insurers made adjustments.

Rates for homeowners’ policies and personal articles placement were each down 1%, and motor was flat.
