I don't think any of this blog's readers will be surprised by this Wall Street Journal article
which shows that many of the best bank deals are at credit unions. And as the article mentions, shared branches and ATM networks can help offset the small size of credit unions. I have more details about this in my credit union post
One problem with the article is that it references Patelco Credit Union
's 5% 1-year CD as an example of credit unions offering better CD rates than banks. It failed to mention that the maximum deposit is $1,000 and it's only for new members. Patelco Credit Union's standard 1-year CD rate is only 0.50%.
Better examples would have been Connexus Credit Union
's 1.75% 1-year CD when the member has an active checking or Melrose Credit Union
's 1.41% 1-year CD.
