From the year-ago quarter, output declined 31.1%. It was the steepest decline in production, both quarter on quarter and year on year, since the first quarter of 2016.
S&P Global Platts began tracking MSHA PRB production data in 2003, when output totaled 400 million st for the year, or an average of 100 million st per quarter, leaving output in the most recent quarter at a record low.
The decline in output was driven by both low demand for thermal coal in power generation and the coronavirus pandemic, which led to over 500 employees being laid off or furloughed by PRB producers beginning in March.
