US Treasuries: pros and risks for retirement income

What are they, and how do they produce income?

US Treasuries are bonds issued by the US government: you lend money to the government, which pays interest at the coupon rate and returns the principal at maturity. By term they split into short (T-Bills), medium (T-Notes) and long (T-Bonds). Income comes in two main forms: hold to maturity to collect each interest payment and get your principal back, giving more predictable cash flow; or trade before maturity on the secondary market, where the price moves with market rates, remaining term and supply and demand, and may be above or below your entry price. Short T-Bills are often issued at a discount — you buy below face value and receive face value at maturity, with the gap being your return and no coupons paid in between. If you want to fit Treasuries into your retirement cash flow, first separating 'earning interest' from 'price gains' is the first step to understanding return and risk.

• Short (T-Bills): one year or less, often issued at a discount, no coupons.
• Medium (T-Notes): about 2–10 years, pay regular interest.
• Long (T-Bonds): over 10 years, pay regular interest and are more sensitive to rate moves.

What are the advantages for retirement income?

• Very low default risk: backed by US government credit and a common market benchmark.
• Predictable cash flow: hold to maturity for regular interest and principal, useful for matching fixed expenses.
• High liquidity: a large, mature market that is generally easier to trade or cash out.
• Diversification: lower correlation with equities helps balance a savings and investment portfolio during volatility.

Advantages depend on how you hold and market conditions; actual returns are not guaranteed, and selling mid-term may still realise a loss due to price swings.

Risks and things to note

'Relatively steady' does not mean risk-free. The key thing to understand is the inverse relationship between rates and prices: when market rates rise, older bonds with lower coupons become less attractive, so their secondary prices fall — and the longer the term, the more sensitive the price usually is to rate moves. Beyond interest-rate risk, retirees should also weigh reinvestment, currency and inflation risk.

• Interest-rate risk: when market rates rise, bond prices fall — selling before maturity may realise a loss; holding to maturity generally does not affect principal.
• Reinvestment risk: at maturity or after interest, you may only reinvest at a lower rate, so long-run income may not stay the same.
• Currency: priced in USD; as the HKD is pegged to the USD, FX risk is relatively limited for HK investors, but the peg and timing of conversion still warrant attention.
• Inflation risk: fixed interest loses real purchasing power in high inflation, so you need other assets to counter longevity and inflation risk.

Investing involves risk; prices can rise or fall. Rate, FX and inflation trends cannot be predicted. Not investment advice — assess for your situation.

How can Hong Kong investors access US Treasuries?

Hong Kong investors can generally hold US Treasuries directly or indirectly in several ways: buying individual bonds through a bank or broker, holding a diversified position via bond funds or Treasury ETFs, or participating through savings/investment products linked to Treasuries. Individual bonds have clearer maturity dates and coupons, suiting a 'hold to maturity' plan; funds and ETFs have no fixed maturity and their prices float continuously, but offer more flexible entry sizes and diversification. If you want to compare relatively low-risk local income options, it is worth also understanding how Hong Kong Silver Bonds work and differ. Before choosing a route, note the fees, minimum amounts, bid-ask spreads and tax arrangements.

Fees, tax and risk differ by route; whether a product suits you depends on your situation. This is not investment or tax advice.

How to fit them into retirement cash flow

Treasuries suit the 'defensive' part of a retirement portfolio, giving relatively stable interest income; but no single tool can balance stability, growth and inflation protection at once. A common approach is to layer Treasuries with annuities, dividend stocks and other income sources: use the steadier part to lock in essential expenses, and keep the rest flexible for inflation and growth. To see how to combine several tools, read our takes on building your own retirement income and retirement passive income.

1. Step 1: Layer your goalsSplit retirement spending into 'essential' and 'flexible' layers, and estimate the stable monthly cash flow you need as the basis for allocating to income tools like Treasuries.
2. Step 2: Consider a laddered structureSpread money across different maturities (a 'bond ladder') so a portion matures at intervals, easing the pressure of reinvesting everything at once when rates are low.
3. Step 3: Combine with other incomePair Treasuries with annuities, dividend assets and more so stable income, growth potential and inflation resistance complement each other, rather than relying on one tool.
4. Step 4: Review regularlyAs rates, inflation and personal needs change, review your allocation and maturity schedule periodically and adjust when needed.

The above is general planning thinking, not a guarantee of any return or income level; see our passive-income and retirement cash-flow articles, and assess actual allocation for your situation.
