Im sure there’s an element of “greedflation” from the manufacturers but if commodities like electricity, oil, gas, wood, electronic components are all going up in price then I would expect those costs to be passed on to the consumer.
Some of these costs may be transitory depending upon geopolitics (labour excluded).
OPEC and Saudi, Sanctions and Russia, Taiwan and China, the US $ and interest rate hikes etc etc
Similarly if a manufacturer wants to borrow money from a bank to expand and increase their productivity (or just modernise, repair and maintain) then those costs are also increasing which will also be passed back to the consumer.
Commercial property is also subject to financing linked to bank lending rates. As the lease rolls over the cost will increase.
Staff will want higher pay.
This is unlikely to be transitory unless the two decades of QE stimulus is continuous in which case any physical good will be a better store of value than the money it’s bought with.
All this stuff is interlinked. Prices of instruments are not in some hermetically sealed bubble.
I suspect prices will continue to rise until central banks either get inflation back to manageable levels (price increases will stabilise but remain higher) or they induce a recession and curtail demand which will lead to deflation.
