During the production curtailment of PSF plants, the stocks of traders were squeezed

During the production curtailment of PSF plants, the stocks of traders were squeezed. Starting about Jun, spot-futures traders accomplished much less orders as PSF plants failed to provide sources. In the meantime, PSF plants dominated more in pricing. The price gap between spot PSF and PSF futures was within 200yuan/mt in early Jun, increased to 600-700yuan/mt in early Jul and hit nearly 900yuan/mt after PSF futures slumped on Jul 13, which was seen for the first time since the list of PSF futures. PSF spread also improved, over 1,000yuan/mt for about half a month.
