Business interruption was up 3 percent compared to 2 percent the previous month, according to the report. Business Owner Policy (BOP) was up 5 percent compared to up 4 percent the previous month.

Also up were:

• Umbrella excess—up 4 percent compared to 3 percent in June.
• Commercial auto—up 5 percent compared to 4 percent in June.
• Directors and officers liability up 3 percent compared to 2 percent in June.
• Employment practices liability insurance up 3 percent compared to2 percent for the previous month.

While the market barometer measures rates compared to the same month a year ago, Kerr notes that rates also saw month-to-month increases in business interruption, BOP, excess liability, auto, D&O and EPLI.

“Each of these coverages was up 1 percent as compared to June 2012,” Says Kerr.

By account size, medium size and large accounts held steady at 4 percent and 3 percent respectively.

Both small accounts and jumbo accounts increased by 1 percent to 5 percent and 2 percent respectively.

Commenting on the results in an analyst's note, Meyer Shields with Stifel Nicolaus says, “We see insurers' deteriorating calendar-year results as the primary catalyst for rate increases, and we expect these increases to accelerate as favorable reserve development subsides and accident-year results edge worse.”

Turning to personal lines, Kerr says, “The market didn't move much from June to July as the composite rate remained at plus-2 percent. The only movement was in personal article floaters, which were up from plus-2 percent to plus-3 percent.”

While homeowners under $1 million in value and automobile remained steady with 2 percent increases, homeowners over $1 million in value rose 1 percent to 2 percent.
