What Are Treasury Bills?

Treasury bills, commonly known as T-bills, are short-term government debt securities with maturities typically of one year or less. They are primarily issued to meet the government's short-term funding needs. T-bills generally do not pay periodic interest; instead, they are sold at a discount and redeemed at face value upon maturity.

From an investor’s perspective, T-bills function like “discounted promises”: you purchase them below face value, and at maturity, the government repays you the full face amount—the difference represents your earnings. Backed by the national government’s credit, T-bills carry low credit risk and are often treated as part of cash equivalents in investment portfolios.

How Are Treasury Bills Issued and How Do They Pay Interest?

T-bills are typically issued via a discount mechanism: instead of paying interest quarterly or semi-annually, they are sold below face value and redeemed at full face value at maturity. The lower the purchase price, the higher the yield if held to maturity.

Issuance is commonly conducted through auction. Institutional investors bid by specifying the price or yield they are willing to accept, and the treasury department sets the winning range and finalizes the allocation. For retail investors, many countries offer “non-competitive bidding,” allowing participation at the final auction result without needing to submit a specific bid.

Where Do Treasury Bill Returns Come From?

Returns on T-bills come mainly from the difference between the purchase price and the face value received at maturity. For example, if the face value is 100 and you buy it for 98, you receive 100 at maturity—the 2 difference is your gain.

When evaluating returns, the term “yield to maturity” (YTM) is often used. YTM annualizes the total return if held until maturity. In general, a shorter holding period or a deeper discount leads to a higher annualized return. Note that if you sell before maturity, market interest rate fluctuations can affect T-bill prices and your actual return may differ from the original YTM.

How Do Treasury Bills Differ from Government Bonds, Bank Deposits, and Money Market Funds?

The main differences between T-bills and long-term government bonds are maturity and interest payment: T-bills have short maturities and use discount pricing; long-term bonds have longer maturities, typically pay periodic interest, and are more sensitive to interest rate changes.

Compared to bank deposits, T-bills are tradable securities whose prices fluctuate with market rates; deposit rates are fixed and usually non-transferable. Money market funds hold baskets of short-term assets (potentially including T-bills and negotiable certificates of deposit), offering minimal net asset value fluctuation but not a guaranteed principal; holding T-bills directly provides clearer terms but requires self-management of maturities and reinvestments.

Why Are Treasury Bills Considered Low Risk? What Risks Do They Carry?

T-bills are viewed as low-risk primarily because they are issued by national governments with a low probability of default and have short maturities that limit interest rate uncertainty. They are commonly used by financial institutions as highly liquid, low-default reserve assets.

However, risks still exist:

• Interest rate risk—if market rates rise, the price of existing T-bills falls; selling before maturity may incur losses.
• Reinvestment risk—upon maturity, new T-bills may offer lower yields.
• Liquidity and transaction costs—bid-ask spreads and fees vary by market.
• Taxation—some jurisdictions have specific tax rules for T-bill income; consult local professionals for guidance.

How Can You Buy and Hold Treasury Bills?

There are three main channels:

1. Direct subscription via government platforms (such as treasury department websites).
2. Purchase on secondary markets through banks or brokers.
3. Indirect participation via money market or short-term bond funds holding T-bills.

Step 1: Confirm compliant channels and eligibility in your country/region, open the required account, and complete identity verification.

Step 2: Select desired maturity and issue. Short terms like 4 weeks, 13 weeks, or 26 weeks are common (varies by country). Match maturities to your anticipated cash needs.

Step 3: Place your order and settle. Direct subscriptions follow auction results; secondary market purchases require attention to net price, full price, and fees. Upon maturity, funds are automatically credited or can be set for automatic reinvestment (if available).

On digital asset platforms such as Gate’s savings or RWA (Real World Asset) sections, products referencing T-bill yields typically disclose underlying assets, yield distribution methods, and risk factors. Before subscribing, review product documentation and compliance disclosures carefully—verify if T-bills are genuinely held, who acts as custodian, and what the redemption process entails.

What Is the Connection Between Treasury Bills and Web3?

The main link between T-bills and Web3 lies in RWA (Real World Asset tokenization). RWA involves representing real-world assets (such as T-bills) on the blockchain as tokens that can be transferred across borders in small denominations with enhanced transparency.

In practice, some institutions package their holdings of T-bills and issue on-chain tokens. The discounted returns are periodically converted into stablecoins for distribution to token holders. Key considerations include regulatory compliance (whether issuance is permitted and which jurisdictions are targeted), custody (broker/bank custody and audits), information disclosure (underlying holdings, maturity structure), and on-chain risks (smart contracts, settlement processes). As of 2025, with rising interest rates attracting attention to short-term T-bill yields, RWA growth is robust (source: public industry research and regulatory bulletins, 2025).

Who Are Treasury Bills Suitable For? How Can You Allocate Them Safely?

T-bills suit investors who prioritize capital preservation and liquidity while accepting minor price fluctuations—especially individuals or institutions managing cash over 3–12 months.

First, clarify your expected cash usage timeline. For short-term reserves, choose shorter maturities to avoid forced sales before maturity.

Second, use a “ladder strategy”—spread funds across T-bills with different maturities so they mature in rotation, smoothing out interest rate swings and reinvestment risk.

Third, consider your channel and costs. Direct investment is more transparent; secondary markets offer flexibility but involve spreads and fees; fund channels offer convenience but charge management fees.

Fourth, set up risk controls and reminders—track maturity dates, automatic reinvestment options, and monitor key events (such as central bank rate decisions) that may impact prices.

What Are Common Misconceptions About Treasury Bills?

Misconception 1: “T-bills don’t pay interest.” In reality, the discount reflects interest paid upfront via a reduced purchase price.

Misconception 2: “Yield to maturity equals final return.” This only holds if held to maturity with negligible costs; selling early means your actual return depends on market prices and fees at that time.

Misconception 3: “T-bills are absolutely safe.” While credit risk is extremely low, prices can still fluctuate—rapid interest rate hikes may lead to declines in market value.

Misconception 4: “Tax treatment is the same everywhere.” Tax rules for discounted income vary by jurisdiction; always check local laws or seek professional advice.

Can You Quickly Recap the Key Points About Treasury Bills?

T-bills are government-issued short-term debt securities with maturities up to one year, generally issued at a discount with returns stemming from the difference between purchase price and face value. Backed by national credit, they offer low credit risk and good liquidity but are still subject to interest rate and reinvestment risks. Purchase channels include government platforms, banks/brokers, and funds; in Web3 contexts, T-bills often serve as underlying assets in RWA products—with compliance, custody, and information disclosure being core concerns. Always consider your own cash flow needs and risk tolerance before investing—evaluate channel costs and local tax rules accordingly.

FAQ

Will I Lose Returns If I Redeem Treasury Bills Early?

It depends on the specific product rules. Some T-bills allow early redemption but will only pay interest based on the actual holding period—this may result in lower than expected returns; others prohibit early redemption altogether. Always read product documentation for redemption terms before buying to understand any potential loss of interest or extra fees for early withdrawal. Choose maturities that match your cash flow needs.

Is Interest Income from Treasury Bills Taxable?

Yes. Interest income from T-bills is generally considered taxable income for individuals and is subject to personal income tax—often at a rate of around 20%, withheld by the issuer or payment agent. Your net income = stated yield × (1 – 20%), so factor this into your calculations upfront. Tax policies may vary by country or region; always consult your local tax authority for specifics.

Can I Use Treasury Bills as Collateral for Bank Loans?

Most T-bill products cannot be pledged as collateral for financing. T-bills are mainly designed for conservative investment purposes with relatively limited liquidity; banks typically do not accept them as loan collateral. If you need liquidity, consider personal loans or other more liquid assets. Specific policies vary by financial institution—consult your bank for details.

Are Treasury Bills Still Worth Buying During Inflation?

Compare yields to inflation rates. If T-bill yields exceed inflation, your purchasing power grows; otherwise it may decline. In high-inflation environments, consider diversifying into inflation-hedged assets such as TIPS or commodities alongside T-bills as a stable portfolio core—not as your sole savings vehicle.

Why Do Treasury Bill Yields Fluctuate?

T-bill yields mainly respond to central bank policy rates: when rates rise, new issues typically offer higher yields; when rates fall, yields drop accordingly. Economic growth prospects, inflation expectations, and market risk appetite also influence yield movements. The yield on purchased T-bills remains fixed if held to maturity—however, selling before maturity exposes you to gains or losses driven by market price changes.
