The takeaway

The market value of US Treasury securities is considered a benchmark for setting other borrowing costs, such as mortgages. It’s considered a benchmark because the US government has not failed to make good on its Treasury debt obligations. So it serves as a baseline for determining the value of other types of securities with higher default risks.

Defining the value of Treasury securities

Because of its importance to financial markets, the “market yield on US Treasury securities at 10-year constant maturity, quoted on an investment basis” is one of the most popular series in FRED. Let’s break down what these data measure, piece by piece.

• US Treasury securities are debt obligations issued by the US government. In this case, it is a Treasury note that pays a fixed rate of interest every six months for 10 years. Because it’s backed by the US government, it’s considered a very safe asset to own.
• Market yield is the return you’d earn if you bought the security today at its current market price and held it until you receive its last interest payment. Although the paid interest rate is constant, economic conditions change over time and the daily price of the security changes, too.
• The label “10-year constant maturity” is a way of reporting what a 10-year note, if issued today, would yield. It is calculated using the yields of other actively traded notes.
• “Quoted on an investment basis” means that the yield is reported as an annualized percentage return. That makes it easier to compare with other investments, such as corporate bonds or certificates of deposit.

Recent behavior of the 10-year Treasury yield

Our FRED graph plots data between May 2021 and May 2026. During that time, the lowest yield value was 1.19%, in early August 2021. Since then, yields have risen as high as 4.98% in October 2023, partly reflecting the more-restrictive monetary policy stance adopted by the Federal Reserve and a generally higher interest rate environment. Check out this recent FEDs note by Daniel Covitz and Eric Engstrom to learn more about the factors that shape long-term Treasury yields.

The takeaway

Firms have intensified their research and development during the AI boom. They’ve reduced their cash holdings, too, likely to pay for R&D. In this post, we use FRED data to explore these trends and the future of AI-related investment.

Background research

Two recent posts from the St. Louis Fed offer insights into AI-related investment:

• A relationship seems likely between rising R&D expenditures and declining cash reserves relative to total assets.
• Significant AI-related investment boosted real GDP growth in 2025 beyond even what IT components contributed during the dot-com boom.

Another analysis projects the AI boom will require $6.7 trillion worldwide in capital expenditures by 2030 to keep pace with the demand for computing power.*

What the data show us

In our FRED graph above, the green dashed line in effect shows the cash holdings of US nonfinancial firms in the corporate business sector as a share of the firm’s assets. We define cash holdings as the sum of checkable deposits and currency, total time and savings deposits, and money market fund shares. (For more about the data, see the Z.1 tables from the Board of Governors’ US Financial Accounts.)

Cash holdings increased from close to 2% in 1990 to close to 4% in the year before the Global Financial Crisis. It increased during that crisis but remained just above 4% in the 2010s. It increased again during the COVID-19 recession, reaching more than 6%. Then it decreased and has fluctuated around 5.5% recently.

With data from the Bureau of Economic Analysis, the solid blue line shows the increase in capital expenditures typically associated with the AI boom. It’s the ratio of private fixed investment in information processing equipment and software to GDP.

The path of this ratio has three distinct phases.

• This ratio surged through the 1990s and peaked at the dot-com crash, followed by a steep decline from 2000 to 2002.
• The ratio remained relatively stable from 2002 through the Great Financial Crisis and into 2023.
• It has jumped sharply from 3.9% in the third quarter of 2023 to 4.7% in the fourth quarter of 2024. It has now surpassed the fourth quarter 2000 peak for the first time.

Future AI investment

As AI-related investment expands further, cash holdings won’t be sufficient to fund it and firms will be more dependent on external financing. Stijn Van Nieuwerburgh argues that the AI buildout has been changing who owns and finances AI infrastructure, as hyperscalers are moving away from fully self-funding data centers and are increasingly combining owned capacity with leased facilities, joint ventures, and partnerships with specialized third-party developers. Monitoring both the adequacy of internal funding and the availability of external finance will be critical for assessing the health of the AI boom.

Data providers may use the same labels for their data even if their methods of collecting the data differ. FRED can help you compare and understand these differences.

Our FRED graph above displays two types of mortgage rates from two different sources: the weekly 30-year and 15-year fixed mortgage rates reported by Freddie Mac (solid lines) and Bankrate (dashed lines). Both data sets show similar interest rates, even though the sources use different methodologies to collect their data. Freddie Mac calculates the average rate on “thousands of mortgage loan applications” from lenders across the country when a borrower applies for a loan. Bankrate reports data from a survey of the “10 largest banks and thrifts in 10 large US markets.”

Use FRED’s graphing features to compare data series visually: This FRED graph shows the entirety of both series, and this FRED graph adds a formula to reveal the differences between the two series, which at times were notably pronounced. You can also download data from FRED to compare series quantitatively and read the FRED series notes to better understand the collection methods used.

We provide another interest rate data comparison for researchers and sleuths with the set of benchmark data from the G.19 Consumer Credit release reported by the Board of Governors of the Federal Reserve System:

• Auto loans at 48 months and 60 months
• Credit cards
• Personal loans

Here are all the recently added series from the Bankrate Monitor National Index and a link to an earlier post discussing recent patterns in interest rates on bank accounts.

How this graph was created: Search FRED for and select “30-Year Fixed Rate Mortgage Average in the United States.” Click on the “Edit Graph” button and select the “Add Line” tab to search for “Bankrate Monitor (BRM): Fixed Mortgage Rate – 30 Year Fixed.” Don’t forget to click “Add data series.” Repeat the last two steps to add data on “15-Year Fixed Rate Mortgage Average in the United States” and “Bankrate Monitor (BRM): Fixed Mortgage Rate – 15 Year Fixed.”
