Where can I find data showing 4-week T-bill rates or U.S. savings accounts' interest rates from 1960s to present, or 1970s to present?

    $\begingroup$ @AlexC The 4-wk T-bill data in that link does not go back to 1970s or earlier. $\endgroup$ – Username Jul 26 '18 at 15:55

Since each bank is able to set their own rates and terms for savings accounts, this is a difficult question.

4 week Treasury Bills only started trading in July 2001. Source: https://www.treasurydirect.gov/indiv/research/history/histtime/histtime_bills.htm

You might want to look at the Federal Funds Yield which is the overnight rate that banks charge each other for loans held at the Federal Reserve Bank of New York.

Recent data is available here: https://www.newyorkfed.org/data-and-statistics

Historical data can be found on the FRED site back to 1954. https://fred.stlouisfed.org/data/FEDFUNDS.txt

  • $\begingroup$ How comparable is the Federal Funds Yield rate to interest charges on depositors’ accounts? $\endgroup$ – Username Jul 28 '18 at 2:22

    $\begingroup$ They are going to be correlated, but you need to take into account that a bank has costs associated with providing a service so the rates are going to be typically about 2% lower but this will vary from institution to institution. For example, I just looked up Citi's savings account interest rate for California, which is 0.04%. The current Fed Fund yield is 1.91%. $\endgroup$ – TraderPatrick Jul 28 '18 at 2:30
