Banks in the euro zone: Why so much hatred?

Share prices of euro-zone banks collapsed in 2018, reflecting investors’ “distrust” in banks. The market valuation of euro-zone banks is now extremely low. Admittedly, the prospect of a yield curve that remains flat in the euro zone is negative for banks; But investors seem to ignore that: Euro - zone companies' financial situation is very good and a cyclical slowdown in euro-zone growth would have little impact on companies’ default rate; From 2010 to 2018 there was no residential real estate bubble in the euro zone, which rules out the risk of a sharp rise in household defaults, especially as long-term interest rates remain very low; Risk-taking by euro-zone banks has decreased markedly in the past ten years and their capital has increased significantly. The collapse in the share prices of euro-zone banks is therefore very irrational.
