The rate of the Constant Maturity Treasury (CMT) and the U.S. Treasury has an important role in determining mortgage interest rates linked with adjustable-rate mortgages (ARMs). Knowing how CMT rates affect mortgage interest rates might assist you in budgeting more effectively. If you plan on purchasing a new or existing home, understanding how the constant maturity treasury rates work, with reference to the 10 and 5 year maturity rate and how they influence interest rates on ARMs, then this article will walk you through all of those details. Let’s proceed. 

What is a Treasury CMT?

Treasury securities, such as U.S. Treasury bills (T-bills), Treasury notes (T-notes), and Treasury bonds (T-bonds), are federal government-backed debt obligations. Holders of these treasury securities (investors), which can be bought and put up for sale on major and secondary markets, get payments in exchange for the funds you will pay to secure them.

  • T-bills: T-bills are short-term debts that mature in less than a year and are often regarded as low-risk investments. The longer it takes for the T-bill to mature, the more interest you can expect to get as a return on your investment.
  • T-notes: T-notes are government-secured debts with a fixed interest rate and maturities ranging from 2 to 10 years. T-note holders get payments every six months until the note matures.
  • T-bonds: These are fixed-rate government debt securities with maturities ranging from 10 to 30 years. T-bonds pay semiannual interest payments to investors until the bonds mature, at which point the owner can expect to be paid the face value of the bond.

The CMT rate is a computed yield generated by taking the average yield of several types of Treasury securities slated to maturity at different timeframes and adjusting it for a number of time periods. It is often displayed to observers in the form of a Federal Reserve Board index that demonstrates to prospective Treasury bond purchasers what kind of average yield they can expect on investments made in these debt instruments.

It’s best to see CMT as a current snapshot that illustrates. Based on patterns in currently traded securities, how much value might ownership of certain types of Treasury securities might ultimately yield if you choose to invest in them?

Constant Maturity Treasury is a collection of “theoretical” securities based on the most recently auctioned “actual” assets: 1-, 3-, and 6-month bills, 2-, 3-, 5-, 10-, and 30-year notes, as well as ‘off-the-runs’ in the 7- to 20-year maturity range. Treasury yield curve rates are another name for constant maturity Treasury rates.

How The CMT Index Affects Mortgage Rates

Consider the CMT Index to be a reference point for financial lenders (banks, credit unions, online lenders, and so on) when determining the cost of variable-rate loans such as adjustable-rate mortgages. Lenders vary the interest rates imposed on these home mortgage programs when market conditions change.

Variable-rate lenders will calculate a mortgage interest rate based on the CMT first. Then add additional percentage points (their margin) to decide how much borrowers will ultimately pay for the loan. Your personal risk profile, credit history, and other characteristics may all have an impact on the mortgage interest rate that is available to you. Yet, as a general rule, as the CMT index rises, any loans that are in connection to it—ARMs and other variable-rate products—tend to rise as well.

When deciding whether to use constant maturity treasury (CMT) rates or other benchmarks to make an informed mortgage or refinance decision, you need to be careful. Keep in mind national economic factors, the global geopolitical environment, and the current state of the real estate and housing industries

Constant Maturity Swaps

Constant maturity swaps (CMS) are a type of interest rate swap that allows the purchaser to fix the duration of incoming flows on a swap. The rate on one leg of a constant maturity swap is reset on a regular basis at or relative to the London Interbank Offered Rate (LIBOR) or another floating reference index rate under a CMS. The floating leg of a constant maturity swap fixes against a point on the swap curve on a periodic basis, preserving the duration of the received cash flows.

In general, after the swap is in place, a flattening or inversion of the yield curve will improve the fixed maturity rate payer’s position relative to a floating rate payer. Long-term rates fall relative to short-term rates in this scenario. While the relative positions of a constant maturity rate payer and a fixed rate payer are more complicated. The fixed rate payer in any swap will benefit the most from an upward shift in the yield curve.

An investor, for example, believes that the general yield curve is set to rise, causing the six-month LIBOR rate to decline in contrast to the three-year swap rate. To capitalize on this shift in the curve, the investor purchases a constant maturity swap that pays the six-month LIBOR rate and receives the three-year swap rate.

Constant Maturity Credit Default Swaps

A constant maturity credit default swap (CMCDS) is a credit default swap with a floating premium that resets on a regular basis, and it serves as a risk-management tool against default losses. At periodic reset dates, the floating payment corresponds to the credit spread on a CDS with the same beginning maturity. The CMCDS varies from a standard credit default spread in that the premium paid by the protection buyer to the provider is floating, as opposed to fixed in a standard CDS.

CMTs and Mortgage Interest Rates

The monthly one-year CMT value is a common mortgage index that is in connection to many fixed-period or hybrid adjustable-rate mortgages (ARMs). As economic conditions change, lenders utilize this variable index to alter interest rates by adding a fixed number of percentage points called a margin to the index to determine the interest rate a borrower must pay. When this index rises, so do interest rates on any loans that are in connection to it.

Certain mortgages, such as payment option ARMs, provide the borrower with a selection of indices from which to calculate an interest rate. Borrowers should, however, carefully analyze this option with the assistance of an investment analyst, as different indices have relative values that have traditionally been relatively consistent within a specific range.

The one-year CMT index, for example, was formerly set lower than the one-month London Interbank Offered Rate (LIBOR) index (LIBOR, however, is being phased out for rate setting).

Hence, when deciding which index is the most cost-effective, keep the margin, or spread, between the CMT and some benchmark rate or index in mind. The bigger the margin, the lower an index’s relative to another index.

What is the 1 year Constant Maturity Treasury?

The term structure of interest rates results in an index that is recognized as the one-year constant maturity Treasury when the average yields of Treasury securities are set to the equivalent of a one-year security.

The US Treasury provides the one-year CMT value on a daily basis, as well as the weekly, monthly, and yearly one-year CMT values. Constant maturity Treasury rates are in use as a benchmark for pricing debt securities issued by firms and institutions.

Tied to the Yield Curve

The yield curve, which is important in creating a benchmark for bond pricing, provides investors with a rapid look at the yields offered by short-, medium-, and long-term bonds. This yield curve, also known as the “term structure of interest rates,” is a graph that displays the yields of similar-quality bonds against their time to maturity, which can range from 3 months to 30 years.

The yield curve has 11 maturities: 1, 3, and 6 months, as well as 1, 2, 3, 5, 7, 10, 20, and 30 years, and the constant maturity treasury (CMT) rates are the yields of these maturities on the curve.

An Interpolated Curve

The CMT for one year is linked to an interpolated yield curve (I-curve). The US Treasury extrapolates the constant maturity yields from the daily yield curve. This is based on the closing market bid yields of actively traded Treasury securities in the over-the-counter (OTC) market and estimated from the Federal Reserve Bank of New York’s composites of quotations.

In this instance, CMT indicates that this interpolation approach delivers a yield for a specific maturity even though no outstanding asset has that fixed maturity. In other words, even though no existing debt security matures in exactly one year, investing professionals can calculate the yield on a one-year security.

What is the 10 year Treasury Constant Maturity Rate Today?

The 10 year rate is the average of the weekly average yield to constant maturity for US Treasury bonds. During a fiscal quarter, Treasury securities (adjusted to a constant maturity of ten (10) years) as published weekly by the Federal Reserve Board in publication H.15, or any successor publication. Or if such a rate is not published by the Federal Reserve Board, any Federal Reserve Bank or agency or department of the federal government selected by the Company.

If, in good faith, the company determines that the 10 Year U.S. constant maturity treasury rate cannot be calculated as provided above. The rate shall be the arithmetic average of the per-annum average yields to maturities. Based on the closing bid prices on each business day during a quarter, for each actively traded marketable U.S. Treasury. Treasury fixed-income security with a final maturity date of not less than eight years and not more than twelve years from the date of the closing asked prices chosen and quoted for each business day in each such quarter in New York City by at least three recognized dealers in U.S. government securities chosen by the Company.

What is the 5 year constant maturity Treasury?

The 5 year Treasury rate at constant maturity is the yield that comes out for investing in a 5-year Treasury instrument issued by the US government. The 5 year constant maturity Treasury rate is in use as a benchmark for pricing other securities, such as corporate bonds. The longer end of the yield curve includes the 5 year constant maturity Treasury rate. In the past, the 5 year treasury yield climbed as high as 16.27% in 1981, when the Federal Reserve was rapidly boosting benchmark rates to combat inflation.

The 5 year constant maturity Treasury rate is 4.03%, down from 4.06% the previous market day and 1.85% last year. This is above the long-term average of 3.74%.

What is the 3 Year Constant Maturity Treasury Rate?

The 3 year constant maturity rate is above the long-term average of 3.36%.

What does CMT stand for Finance?

CMT is an abbreviation for Certified Market Technician in finance (CMT).

To Conclude

CMT rates can have a significant impact on adjustable-rate mortgages and other variable-rate home loan products, so you should be aware of them before applying for a mortgage. Mortgage interest rates climb in lockstep with market rates, and the higher the interest rate, the more you may anticipate paying each month.

Your mortgage interest rates are not primarily set by U.S. yields on government securities. Understand how lenders calculate mortgage interest rates and what factors influence loan payments to get the best mortgage rate possible.
