China's pig iron market price from July 2016 1700RMB per ton rised all the way to March 2017 3200RMB per ton, reaching 188.2%. But from April to June it fell to 2650RMB tons,decline by 17.2% than March. Dinsen analysis for the following reasons:

1)Cost:

Impacted by steel shock adjustment and environmental, steel supply and demand market is weak and price continue to be lower. Steel factories have enough coke stock and not enthusiastic in coke purchases,cost support weakening. Demand & cost are both weak, coke market will continues to weaken. In total, the materials and cost of supporting will continue to weaken.
 

2)Requirements:

Under the influence of environmental protection and capacity, some parts of steel and foundries stop production. What’s more, lower price scrap impacts that foundries have increased the amount of scrap steel and cut down or stop using cast iron. Thus pig iron market demand shrink and overall supply & demand are weak.
 
In short, the current cast iron market is in supply and demand weak state and short-term demand never better. Coupled with ore and coke continue to weaken, iron price will continue to decline. But not too many iron factories are in production, inventory is still in control and price falling space is limited , mainly short term pig iron market is expected to slightly lower.
