Apparent steel supply remains strong through September
Written by Brett Linton
The volume of finished steel entering the US market grew in September, driven primarily by higher domestic mill shipments, according to SMU’s analysis of US Department of Commerce and American Iron and Steel Institute (AISI) data. This “apparent steel supply” metric is calculated by combining domestic mill shipments with finished US steel imports then subtracting total US exports.
September supply increased 1%, or 94,000 short tons (st), from August to 8.64 million st and was 7% higher than the same month one year prior. Strong domestic shipments were the primary contributor to supply this month, more than compensating for the decline in finished imports. September supply is about 110,000 st higher than the average supply rate seen over the past year.
