Here are the latest money market interest rates of the banks that I've been tracking on my blog. Note that these rates are sorted by APY, and represent institutions that I have accounts at, or have otherwise mentioned in my blog:
0.85% American Express High Yield Savings
0.85% FNBO Direct Online Savings
0.84% Ally Bank Online Savings
0.80% Discover Bank Online Savings
0.75% Capital One 360 Savings (formerly ING Direct)
0.70% Urban Partnership Bank Online Savings
0.20% Western FCU Money Market
0.10% Chase Plus Savings
0.10% Citibank Savings Plus
In some cases, MMA interest rates are tiered. If this is the case, I usually report the interest rate at the $10,000 tier in these updates.
Rates are believed to be accurate as of 3/11/13. I did not include banks that had special, or introductory rates in the list because they are not ongoing interest rates. I am also not including non-liquid accounts such as CD's in the list. I have included a few credit unions in the list so that readers have a comparison point with banks.
It seems the Ally Bank Online Savings has dropped a couple of notches from the top position on this list. Also, ING Direct has been replaced by Capital One 360.
The frequent changes show how changeable the money market is. Because this is a constantly moving target, it has been very hard to keep track of the rates that I've been getting in my various money market accounts, and this is the main reason I've decided to compile a list of these annual percentage yields.
So, that is the latest list of money market rates. Please let me know if you know of any higher interest rates.
