Decline in int'l oil prices is expected to negatively affect E&P sector's profitability. A $10/bbl change in oil prices alters sector's FY13 earnings by 6.3 per cent with POL being the most sensitive (7.0 per cent), while OGDC and PPL earnings change by 6.5 per cent and 5.9 per cent, respectively. For refineries, reduce prices means lower benefit of deemed duty in absolute terms and result in inventory loss. For every $10 change in the oil prices, deemed duty changes by $1.4/bbll, which effect NRL and ATRL annualised earnings by Rs3 and Rs2 per share. However, for NRL, the reduction in oil prices bodes well for lube margins at least in the short run. Decline in coal prices could further improve margin of local cement manufacturers. Our estimates suggest that every $10 per ton decline in coal price improves DGKC and Lucky FY13 earnings by 8-9 per cent Similarly, falling steel prices bodes well for Auto Assemblers and slightly improve their margins, assuming Rs-Yen parity to remain same.Compared to other commodity prices, international urea and DAP prices remained relatively immune.
