For March, the most recent month for which data is available, the TCI came in at -7.38, down significantly from February’s 12.06 reading, a month that show growth over January’s 11.46, driven by what FTR, at the time, called a “sizable increase in fuel costs as freight rates were strong and freight demand improved.”
