An Econometric Modelling Method
Steel worth forecasting is considerably basic to all investment decisions in the iron and steel sector. Current volatility in steel prices however has been unprecedented. The worldwide steel markets noticed prices for hot rolled steel coil – very a lot a ‘benchmark’ steel product – rise from below $600/tonne in the first quarter of 2008 to nearly ~$one thousand/tonne by mid-2008. Just some months later, by early 2009, the hot rolled coil price was beneath $500/tonne, with comparable worth oscillations seen for reinforcing steel bar. Such wild and sudden swings in the worldwide steel price have hardly ever if bakken oil prices today ever been witnessed before.
For some months after the onset of the crisis, it was felt bakken oil prices today that it would be several years and even longer before costs would return to the heady ranges of mid-2008. But within the January 2011, discussions again turned to benchmark steel prices hitting $one thousand/tonne within a matter of months. The scene is set therefore for what may be very rather more variability in steel pricing in the future than has been evident up to now. In these circumstances, the ability to accurately decide future steel price movements becomes but tougher.
An econometric value forecasting mannequin
A statistical strategy to price forecasting might be made, utilizing econometric modelling methods. Econometrics are outlined as the application of mathematics and statistical strategies to the evaluation of economic knowledge, so the approach must be effectively suited to the task. On this foundation, a mathematical mannequin was developed by MCI whereby:
– month-to-month historic prices for scorching rolled steel coil and reinforcing bar have been gathered throughout a 16 year time horizon
– monthly costs had been additionally gathered for a range of commodities, including crude oil (as an indicator of commodity costs, generally), pure gas (as an necessary energy source for steel pants), thermal coal (as an necessary gasoline e.g. for steel energy plants), metallurgical coal (used within the blast furnace), electricity costs (used to power electric arc furnaces), iron ore (as a dominant supply of iron units for primary oxygen steel making), ferrous scrap (as a dominant supply of iron items for electric steel making)
– statistical correlations (i.e. the mathematical mannequin) were established between the steel merchandise on the one hand; and the commodity costs on the other.
The steps above allowed a mannequin to be developed between historic worth of hot rolled steel coil and rebar; and the opposite commodity prices. The strategy showed that some components comparable to coal and scrap costs correlated very well with the historic steel worth, whilst other value factors (e.g. electricity prices) didn’t.
Looking ahead, independent estimates of future commodity prices have been obtained from main sources such as the World Financial institution and the Vitality Data Administration. These forecasts were then plugged into the mathematical mannequin obtained above.
