Hope this makes more sense.

If you need raw materials W and X and Y to make industrial product Z, and the limiting factor is Y, then there is less need for W and X.

What if those first in the queue get the Z (on time), and those who are later in the queue risk missing out (or paying more elsewhere).

Then the demand for W, X and Y may spike initially. Then depending on other demand factors, W and X will sit around waiting for enough Y to make Z.

W, X, Y, Z are Iron, Nickel and other inputs, Metallurgical Coal, Steel. (approx)

I'm no expert - please set me straight if you know I am wrong.
