 Bottom Line • Potash demand drivers are strong – High agricultural commodity prices – Strong speculative interest – But solid underlying agricultural fundamentals – Positive farm economics/income worldwide – Lean K distribution pipeline – Low K levels in soils • Potash shipments are back on track – Global shipments forecast to increase to 48-49 MMT in 2010 and to 52-55 MMT in 2011 – Broad-based demand recovery – NA shipments forecast to climb to 10 MST in 2010/11 based on higher acreage and rate recovery – “Perfect Storm” fall season in NA but half of projected demand still ahead next spring • Producers struggled to keep up with peak shipments this fall • Market is expected to remain tight until new capacity comes online later this decade 23 |
