As my emigration process moves along, I'm starting to think about where to keep assets. IBKR and Schwab are likely, but I would like to have some Euro-denominated (and EU law controlled) investments as well. Do folks have suggestions for how to start educating myself about this landscape?

Initially, I'd want to bring a significant amount of cash over and put it somewhere that is not losing ground to inflation. There are some EU banks that pay interest, though more modest rates than in the US. But assuming it's possible as someone on a long-term resident permit in PT to open a local brokerage account, I'm hoping there are funds / ETFs I will be able to purchase comparable to VUSXX or SPTS. Also hoping the account opening process will become less onerous once I'm actually resident there - getting a PT bank account opened from the US was quite a lot of hassle.
