The answers showed some ways with way under 2%, so I figured something had to be wrong. Looking up US MMAs, I typically found only around 1%, which is dramatically lower.
The only reason I could think of is the FED's prime rate is only 0 - 0.25 while ECB's is 1.25. Did I miss something?
Additionally, is there a good way for an investor as in the linked question (6-9 month) to still profit from Europe's higher interest rates? I could imagine exchanging USD to EUR and back easily eats up all gain.
