The yields above are par yield curve rates published each business day by the U.S. Department of the Treasury. They represent the yield a Treasury security would pay if it were priced at par, interpolated across maturities from 1 month to 30 years, and are the standard reference rates for pricing bonds, mortgages, and corporate debt.
The 10s–2s spread — the 10-year yield minus the 2-year yield — is the most watched recession signal in fixed income. When it turns negative the curve is “inverted”: short-term money costs more than long-term money, which has preceded most modern U.S. recessions. Our Treasury yield curve page breaks down the curve’s shape, every spread the market quotes, and each inversion episode of the past five years.
SOFR (Secured Overnight Financing Rate) is the reference rate that replaced LIBOR after its 2023 retirement. It is published daily by the New York Fed from actual overnight repo transactions, and now underpins most floating-rate loans and derivatives that once referenced LIBOR.
Corporate bonds yield more than Treasuries of the same maturity, and the gap — the credit spread — is a market gauge in its own right. Our corporate bond yields page shows the high-quality corporate curve from 1 to 30 years next to the matching Treasury yield, with the spread history back to 1984.
Monthly report. On the first of every month we publish a Treasury yields and bond market monthly report: the full curve with its month-over-month and year-to-date moves, the Fed and inflation backdrop, bond ETF performance by segment, and the dated catalysts ahead.
Savings bonds work on entirely different rules from everything above: they do not trade, have no market price, and cannot lose value. If that is what you are looking for, start with what a savings bond is and the difference between the two series, go straight to the current I bond rate, or find out what a bond you already own is worth with the savings bond calculator.
