The latter item appears to be the bigger risk at the moment, and a pronounced slowdown or recession will postpone or even eliminate any significant tightening in the marketplace.”While the economic landscape is muddled with conflicting pros and cons like lower gas prices compared to a year ago and loose capacity as part of the former and sluggish industrial output and cautious consumers as part of the latter, ongoing uncertainty is having an impact on shippers’ supply chain operations from various perspectives, including strategy, planning, and procurement.This, in turn, has seen shippers try to lock in more contractual pricing instead of spot pricing, with carriers able to leverage that into future capacity commitments.Industry stakeholders have told LM 2016 is has been an interesting one for shippers to date, depending on economic growth levels and expected significant impact of industry regulations like electronic logging devices, and the possible resumption of motor carriers hours of service rules, among others.Stifel analyst John Larkin succinctly summed up the current capacity outlook in a recent research note.
