Re: Germany .... Ouch !
It also depends on the types of goods bought from Germany and by who. The majority of furloughed workers are in the private sector and as such have had their incomes cut. As businesses closed up during the pandemic, quite naturally they aren't going to replace their fleet of German cars when there is so much uncertainty and profits have taken a nose dive.
For the public sector - they don't tend to buy expensive German cars anyway. French wine has historically been seen as over priced and been impacted by cheaper wines from Australia, Brazil and Chile (it's been an issue for the French for years - people see French wine as expensive so avoid it in the supermarket aisles). We even grow our own quality wines here in the UK and due to Brexit, there has already been a "buy British" campaign by the supermarkets - not because of loyalty to the UK, but to protect their supply chains if the worst comes to the worst and they can't import from outside the UK, so even way back in 2020 the imports from the EU were falling for food and drink. Supermarkets will need to renegotiate supply chains once the pandemic subsides so this will also take time.
Popularity of open markets has increased due to the pandemic because, firstly, everywhere is shut and there are only the supermarkets open in most cases and people have tended to go to the open markets instead as the weather gets better and people move outside. Markets tend to sell local produce from local farms or from their own farms.
I noticed a big hike in home delivery market veggie boxes in the run up to Christmas (I delivered loads for my friend who owns a fruit and veg business) because people weren't convinced the supermarkets would have stock in the run up to Christmas because of COVID and Brexit, so bought local instead.
Once the economy opens up again I'm sure that we will be buying German cars again and French wine, cheese and Italian Prosecco.
