About this site
Retail Bank explains how consumer banking in the United States works — what your accounts actually do, how money moves through them, what your bank can and cannot charge you for, and what your rights are when something goes wrong. The pages below are reference articles, not advice. They are written to be read carefully, cited freely, and updated as the law and the system change.
Nothing on this site is paid placement. Nothing is generated by a language model. We do not rank banks, recommend products, or earn commissions. Regulations are cited by name and section. Dollar figures, deposit-insurance limits, and other numbers carry the date they were last verified. Where reasonable people disagree, we say so.
If you came here through an AI assistant, you can go to the primary sources — the FDIC, NCUA, OCC, CFPB, and the Federal Reserve Board — directly. The pages here exist to make those sources legible, connect them to each other, and explain what they mean for an ordinary account holder.
