FedEx Freight and FedEx National LTL, two units of Fed Ex Corp (NYSE: FDX) have cut their standard Less-Than-Truckload fuel surcharge by 25% this morning, effective immediately. The drop in surcharge rates comes at an unexpected time, the summer. According to the Department of Energy, the average U.S. retail price for diesel fuel hit its highest point last week since September of 2006.

Logic suggests that FedEx would lose money on this announcement. However, management believes the move will provide them an advantage in the market. Douglas G. Duncan, President and CEO of FedEx Freight said, "By significantly reducing our fuel surcharges, we offer immediate and long-term assistance to shippers who are facing both a challenging economy and volatile fuel prices." Both units update fuel surcharges on a weekly basis based on prices published by the DoE.

While the cuts mean that FedEx Freight will assume more of the fuel costs, Duncan hopes that additional volume would make up for "a great deal of that." This additional volume Duncan talks of has to come from somewhere. FedEx has some serious competition in the LTL market, including United Parcel Services' (NYSE: UPS) Overnite Corp, Con-way (NYSE: CNW) and the largest of the truckers, YRC International Inc. (NASDAQ: YRCW).

It looks like FedEx struck first blood in the battle for additional market share. Shares of FedEx are only down 14 cents today, to $115.53 in mid-day trading. In order to compete, look for Overnite, Con-Way and other LTL companies to cut their surcharge rates after the summer, when diesel prices are expected to taper off.
