Many businesses currently have severe supply issues. Prizes for computer chips are 100 times higher in some cases. The situation is a bit better now but many could not produce as much as they wanted in the past quarters. Now many businesses run extra work shifts because there are massive back orders. My company could send sales into holiday until mid 2023, they currently basically sell stuff that doesn't exist...

But computer chips are just a small part, inflation is mainly driven by energy prices right now. Germany's economy is also heavily globalized and any conflicts or reduced global trade will hit the economy pretty hard.

Still, exports totally were just reduced by ~ .5% while imports increased by 2.7%. But these small percentages already create an imbalance.
