Sure..how is JPMorgan doing? UBS? Wells Fargo? Citi?or just think for yourself how is it that Deutsche Bank, one of the biggest banks in the world, keeps losing billions of euros every year.
Sub zero interest rates of course hit banks, they are not allowed to take risks after the financial crisis so one of their main sources of income which is government bonds pays zero
Deutsche is exposed to German bonds which pay sub-zero, that's the reason why they are struggling
Do you even know how banking works besides it being the place where you park your money as an alternative to the mattress?
banks hold long term assets (loans) financed by short term liabilities (deposits)
