Reefer leads big rates surge in May

May ratesReefer rates on the spot market hit an all-time high in May after skyrocketing 29 cents in May to $2.41 per mile, according to data released this week by online loadboard Internet Truckstop.

The 29-cent jump is the latest in a string of monthly jumps since February, as reefer rates have risen 53 cents in that time period.

Van rates also saw a big boost in May, rising 15 cents to $1.98 per mile, nearly hitting the $2.01 per-mile high van rates reached last summer. Van has climbed 32 cents since February.

Flatbed rates rose another 2 cents last month and have climbed 13 cents since February. For flatbed, that’s a significant increase, as its price is much less volatile: The monthly per-mile rate has been between $1.90 and $2.10 since February 2011.

The trends in all three segments mirror the last two years, in which rates rose in the spring and early summer from downward winter trends.
