Global raw steel production slowed for the fourth straight month in September, according to the latest figures from the World Steel Association (worldsteel). After falling 3.4% month over month (m/m) in August, the total volume of raw steel produced around the globe ticked down 1.2% to an estimated 142.4 million metric tons (mt) in September. Output was down just 0.1% year over year (y/y). On a 12-month moving average (12MMA) basis, annual production has averaged 149.3 million mt per month across the past year. This was down 1.6% y/y and was the lowest 12MMA since May (Figure 1). Before September 2025, annual output had generally hovered between 152 million mt and 154 million mt for over three years, similar to pre-pandemic levels.
