Bank's Net Interest Margin for World:
|It was almost zero. Then, suddenly, four percent.|
After 1996 it jumps way up, all of a sudden. I don't like big mysterious changes.
See the first word of the series title? Bank's. One bank. Belonging to one bank.
One global bank? That can't be right. In the future, maybe, but not yet. So I don't know what this graph shows.
I did a quick google. Found A Quick Comparison Of Interest Margins For The Largest U.S. Banks from Forbes. Dated 11 September 2014, just a few months back. Here is the opening sentence:
Net interest margin figures for all banks in the U.S. have been on a steady decline over the last three years as a direct result of the low interest rates being maintained by the Federal Reserve since the economic downturn of 2008.
Forbes is worried about a decline that doesn't stand out on the graph. I think they are making an argument without really having one. Their evaluation seems one-sided.
What I want to know is what law was changed, to let that thing jump up so suddenly after 1996?
