Tbill Rates Explained: A Guide to Treasury Bills

Treasury bills, or T-bills, are short-term government securities with maturities ranging from a few weeks to a year.

The shortest T-bill is the 4-week bill, which is auctioned off by the US Treasury every week. This is a relatively short period of time, but it's long enough for investors to earn some interest on their money.

T-bills are considered to be very low-risk investments because they are backed by the full faith and credit of the US government. This means that investors are highly unlikely to lose any of their principal investment.

Treasury bills are sold at a discount to the par value, which can be thought of as the maturity amount. The discount rate or discount yield is calculated as a percentage.

The formula for calculating discount yield is as follows: T-Bill reference rates can be obtained directly from the US Treasury website. The difference between the face value of the T-bill and the amount that an investor pays is the discount yield.

You can purchase Treasury bills in three ways: non-competitive bid, competitive bidding auctions, or through a bank or a broker. In a non-competitive bid, the investor agrees to accept the discount rate determined at auction.

The purchase price of a T-bill can be calculated using the formula: Price = Face value (1 – (discount rate x time)/360). For example, a $1,000 26-week bill sells at auction for a discount rate of 0.145% and sells for $999.27.

A non-competitive bid is a way for investors to purchase Treasury bills with a guaranteed return.

In a non-competitive bid, the investor accepts the discount rate determined at auction, which is equal to the average auction price for T-Bills sold at auction.

The yield that an investor receives is guaranteed, and payment is made through TreasuryDirect or the investor's bank or broker.

You can purchase Treasury Bills through three main ways.

One way is through a competitive bidding auction, where investors submit bids stating the lowest rate or discount margin they're willing to accept.

In a competitive bidding auction, bids accepting the lowest discount rate are accepted first, and the process continues until the entire issue is sold.

Purchase payments must be made either through a bank or a broker.

A strong U.S. economy tends to make corporate debt more attractive than government debt, decreasing demand for U.S. debt and raising rates.

The economy's performance plays a significant role in determining Treasury bill rates. A weaker economy promotes a "flight to quality", increasing the demand for Treasuries, which leads to lower yields.

Macro-economic conditions, such as inflation and monetary policy, also impact Treasury bill prices. Investor risk tolerance and specific supply and demand conditions for T-Bills are other crucial factors to consider.

The Treasury yield curve reflects the cost of U.S. government debt and is ultimately a supply-demand phenomenon. This means that supply-related factors, such as central bank purchases and fiscal policy, and demand-related factors, such as the fed funds rate and inflation, all shift the yield curve.

The yield curve can be affected by various factors, including the trade deficit, regulatory policies, and inflation. These factors can influence the attractiveness of Treasury bills to investors and ultimately impact the rates.

Here are some key factors that affect Treasury bill rates:

Treasury yields are determined by interest rates, inflation, and economic growth, which also influence each other. This complex relationship affects the demand for Treasury bonds and ultimately determines their yields.

Inflation erodes the value of future coupon and principal repayments, so the real interest rate is the return after deducting inflation. This is reflected in the Treasury yield curve, which shows nominal interest rates.

Strong economic growth leads to higher treasury yields, as fixed-income products become less in demand. This is because investors seek higher returns to compensate for the expected higher inflation.

The price of T-Bills can be affected by the prevailing rate of inflation, which eats away at the real purchasing power of the T-Bill. If the inflation rate stands at 5% and the T-Bill discount rate is 3%, it becomes uneconomical to invest in T-Bills.

The yield curve reflects the market's inflation expectations, among other factors, and can change in various ways, including shifting up or down due to unanticipated events.

In the US Treasury market, T-bill rates are influenced by market and auction information. The Treasury Department auctions off T-bills at a fixed rate, which can affect the overall rate.

The frequency of these auctions varies, with weekly auctions for 4-week and 13-week bills, and monthly auctions for 26-week and 52-week bills. This regular schedule helps to maintain liquidity in the market.

The auction size and frequency can impact the T-bill rate, with larger auctions potentially driving down rates due to increased demand.

Competitive Bidding Auctions are a type of auction where investors buy T-Bills at a specific discount rate they're willing to accept.

In this type of auction, each submitted bid states the lowest rate or discount margin the bidder/investor is willing to accept. Bids accepting the lowest discount rate are accepted first.

The process continues until the entire issue has been sold, with purchase payments made either through a bank or a broker.
