A US Grains Council market perspectives report from September 21 notes dry bulk freight rates appear to be losing steam after a two-month run-up, with markets mostly steady. It also reports the Brunswick, Georgia grain port was damaged by a recent hurricane, with repair timing for grain loading unknown.
Damage to the Brunswick port removes an export outlet for US Southeast grain, potentially tightening logistics and shifting flows to other Gulf and Atlantic ports, with mild upward pressure on regional basis and freight.
