The indicator is published by U.S. Department of the Treasury on a daily basis and is one of the primary datasets used by investors and economists to monitor this area of the economy. Yield, in percent per year, that the Treasury reads off its par yield curve at a one-month maturity. It is a constant maturity yield on bills, quoted on a bond-equivalent (investment) basis, and it is not seasonally adjusted. ## Why Investors Watch 1-Month Treasury Yield The one-month yield sits closest to the overnight policy rate, so it tracks where markets expect short-term borrowing costs to settle over the coming weeks. Bill supply, money market fund demand and debt-ceiling episodes can also move it apart from policy expectations. The indicator's impact on financial markets depends on multiple factors: whether the reading was expected, the current economic regime, central bank policy stance, and investor positioning. A single data point is rarely sufficient to draw firm conclusions. ## How 1-Month Treasury Yield Is Calculated Treasury fits a yield curve each business day to indicative bid-side prices for the most recently auctioned bills, notes and bonds, collected near 3:30 p.m. ET, using a monotone convex spline method. The one-month point is read from that fitted curve rather than from one specific bill, which is why it is called constant maturity. The official methodology documentation from U.S. Department of the Treasury describes the full calculation process including sample design, weighting and revision procedures. **Reference:** [U.S. Department of the Treasury: 1-Month Treasury Yield data and methodology](https://home.treasury.gov/policy-issues/financing-the-government/interest-rate-statistics) ## Release Schedule and Revisions 1-Month Treasury Yield is typically released daily by U.S. Department of the Treasury. Release dates are announced in advance through the official release calendar. Investors should monitor both the scheduled release dates and any unscheduled revisions. This series is a market-observed price, rate or index level, so the published value is not normally revised after release. Check the publisher's notes for the occasional correction or methodology change. ## How to Interpret 1-Month Treasury Yield Changes When analyzing 1-Month Treasury Yield data, investors should consider multiple dimensions simultaneously: - A rising 1-month yield mostly reflects expected or actual increases in the Fed's policy range, because bills this short reprice almost one for one with policy. - Compare it with the federal funds target range and the 3-month yield: a gap to the policy rate shows how much of an imminent move is priced in. - It is a bill yield, not a credit signal, so sharp spikes can come from debt-limit episodes or large changes in bill supply rather than from economic news. ## Market Impact of 1-Month Treasury Yield 1-Month Treasury Yield can influence multiple asset classes depending on its implications for economic growth, inflation, and monetary policy: - **Equities:** Changes in 1-Month Treasury Yield can affect earnings expectations, discount rates and sector rotation preferences. - **Fixed income:** The indicator may influence Treasury yields and credit spreads depending on its monetary policy implications. - **Currency markets:** Divergence in 1-Month Treasury Yield across economies can affect relative currency valuations. - **Commodities:** Economic activity indicators can affect commodity demand expectations and prices. ## Historical Context 1-Month Treasury Yield has a long history that provides context for interpreting current readings. Key reference points include major economic cycles, recessions, recovery periods and policy regime changes. Historical comparison helps investors avoid placing excessive weight on any single data point outside its longer-run context. Investors should be aware that methodology changes over time can affect comparability across long historical periods. The official U.S. Department of the Treasury documentation will note any significant definitional or methodological changes. ## Limitations of 1-Month Treasury Yield Like all economic indicators, 1-Month Treasury Yield has limitations that investors should understand before drawing conclusions: - Very short bills are sensitive to Treasury cash management and debt-ceiling standoffs, so day-to-day moves can reflect supply and demand technicals, not policy expectations. - The value is a fitted constant-maturity point on a curve, not the yield of one specific bill, and it uses a bond-equivalent basis that differs from the discount rates in auction headlines. - No single indicator captures the full complexity of economic conditions, so read this series next to the ones linked below. ## Related Economic Indicators 1-Month Treasury Yield is best interpreted alongside related indicators that provide complementary perspectives on the market yield on 1-month U.S. Treasury securities at constant maturity.
