Why don't construction prices go down?

Exactly, once the price has been up there and has been paid, it stays there. Or only goes back a fraction of the increase. It's the same with fuel. Oil is long back to pre-war levels, yet fuel is still at 1.80 and more.

This argument is convincing. If we move forward on the timeline, there is a likely scenario that could bring prices down: a sustained recession. Whether this lasts depends on the interest rate policy of central banks and the willingness of the state to provide fiscal stimuli. I found the experience report from the comment here before interesting.

The fuel is also artificially made more expensive by the CO2 tax. For petrol, nearly 14 cents/liter...

What I also wanted to express: other times will come for the manufacturers as well. Times when production costs can also increase sharply again. Then it is not always straightforward to immediately pass on these price increases. Therefore, in my opinion, one cannot always expect prices to be immediately reduced for the customer when production costs decrease.

Because there is no real market price for fuel. Ecosystem services are free and therefore not captured by the market mechanism. It only knows prices. However, these services are not always free and someone has to bear these costs at some point somehow. This can always only be done artificially, how else?

There is still a lot left with a difference of 40-50 cents compared to earlier. The real culprit is not to be found in the CO2 price, which is, by the way, well below the market price. So rather artificially discounted.
