I was going to purchase a shipping container for my property in the US a few days ago, but the company I was talking with has raised their prices 70% over the quote I got 2-3 weeks prior.
No because containers are in high demand overall. While the US is importing less, stuff to the EU is taking the long way around Africa and that means more containers are needed.
Both of those are factors. There are other factors neither one of us knows about (even if you are in ocean transport - your competitors are doing things they are hiding from you until they happen). How they balance out is not something I know, someone in the field likely has a reasonably good idea despite not knowing everything.
Containers are also manufactured… in China. Container, sea and others, are products in and of themselves so importing them for use even just to transport goods domestically will cost more.
