When there is zero or negative interest rates, central banks are printing money and giving it to banks for free. So, Western banks are no longer interested in traditional business of loans and deposits. Instead, they deal in roundabout trades among themselves and give everyone in their tribe big bonuses/commissions in addition to fat pay cheques. Looks like the end is near. It must be extremely difficult for economics or finance teachers to give real-world examples when every thing’s so crooked.
“There was a crooked man
There was a crooked man, and he walked a crooked mile,
He found a crooked sixpence against a crooked stile;
He bought a crooked cat which caught a crooked mouse,
And they all lived together in a little crooked house.
