“It wasn’t until 1974, when the Equal Credit Opportunity Act passed, that women in the U.S. were granted the right to open a bank account on their own.

Technically, women won the right to open a bank account in the 1960s, but many banks still refused to let women do so without a signature from their husbands. This meant men still held control over women’s access to banking services, and unmarried women were often refused service by financial institutions.” https://www.forbes.com/advisor/banking/when-could-women-open-a-bank-account/
