business volume decrease is, imo, very logical consequence given the pandemic situation.
My guess is that reason for it is this time on both sides of S-D relation.
We usually see pressure from either demand side or supply side, but this time I think there is "shock" on both sides. And both sides somehow move against each other so the equilibrium is not that much changed.
I think that they will both continue to negate itself and some drastic price movement is very unlikely in the near future.
The long term is kind of unchartered territory so who knows.
It will very much depend on the outcome of vaccination and development of pandemic situation.
