11th District Cost of Funds Index
  
It's like an index of checking and savings account bank interest rates on the West Coast. The 11th district comprises AZ, CA, and NV, and has nothing to do with an angry, teenage, Establishment-hating J-Law (totally different District). It comes out at the end of each month and tracks inflation...kinda sorta. At least in a rearview mirror. Think: lagging indicator. The East Coast kissin' cousin is The Treasury Index. Costs of funds - or the cost of renting money - is a big deal since the market itself is trillions and trillions so even one basis point change, is some incremental tens of billions of dollars in delta.
