What it means
The product works like a long-term deposit with an insurer. The saver pays in a lump sum, the insurer promises a fixed rate for a set number of years, and the income is paid monthly, quarterly or annually.
At maturity, the capital is repaid in full unless the terms say otherwise. The rate on offer is fixed on the day the bond is bought, so it does not rise or fall with markets.
The insurer invests the money mainly in government and high-quality company bonds, earns a return and keeps a margin. This is why the rate offered tends to follow the level of interest rates in the wider economy at the time of purchase.
Predictability is the main attraction. A retired person might use the income to cover regular household costs, and a business owner might park spare cash for a few years with a known return.
Because the figures are fixed in advance, they are easy to include in a budget or a cash forecast. The guarantee is only as good as the provider behind it.
It depends on the financial strength of the insurer, and the level of any protection from a compensation scheme varies by country and by product. Savers should check the provider's rating and the rules that apply to their own situation.
There are other trade-offs. Cashing in early can mean a penalty or a loss of capital, and a fixed income loses buying power if inflation rises.
Tax treatment also differs between jurisdictions, so the after-tax return can be lower than the headline rate. Comparison shopping is sensible.
A saver should look at the rate, the term, the provider's financial strength, the exit terms and the tax position, and then compare the bond with a plain fixed-term deposit or a government bond. The best choice depends on how long the money can be tied up and how much risk the saver is willing to accept.
In practice
Real-world examples.
Example
A retired teacher places $150,000 of savings in a 5-year bond and takes the income quarterly. The payments cover her utility bills and insurance without her having to sell any investments. She records the maturity date in her diary so she can plan what to do with the capital. She also keeps an emergency fund elsewhere, because the bond cannot easily be cashed in.
Example
A small consultancy has $80,000 of spare cash that it will not need for three years. The owner buys a bond with a fixed rate rather than leaving the money in a current account. The finance adviser notes the interest as investment income in the accounts. She also checks the provider's credit rating before the cash is transferred.
Example
A couple saving for a house purchase in four years buy a bond that matures just before the planned completion date. They know exactly how much they will have, which helps them agree a mortgage. They accept that they cannot easily withdraw early without a penalty. They keep a separate cash buffer for any unexpected costs before the completion date.
Formula
Calculation
Annual income = amount invested x guaranteed rate
Total income over the term = annual income x number of years
Suppose a saver invests $100,000 in a 5-year bond that pays a guaranteed 4% a year. Annual income = 100,000 x 4% = $4,000.
Total income over 5 years = 4,000 x 5 = $20,000.
Total received including the return of capital = 100,000 + 20,000 = $120,000.Case study
Seen in the real world.
Hartwell Family Office is a fictional adviser helping a client who feared another stock market fall. The client, a recently retired engineer, wanted a steady income and had little appetite for risk.
The adviser proposed placing part of the client's savings in a five-year guaranteed income bond while keeping the rest in a diversified portfolio. The illustrative bond paid a fixed rate and returned the capital at maturity, giving the client a dependable base of income.
When inflation later rose, the real value of the income fell, a point the adviser had explained at the start. The client remained comfortable because the bond was only one part of a wider plan. The adviser reviewed the plan each year, and at maturity the pair discussed whether to buy another bond at the new rate or to move some capital elsewhere.
Watch out
Common mistakes.
- Assuming the guarantee means there is no risk at all, when it depends on the provider's ability to pay.
- Ignoring inflation, which can reduce the buying power of a fixed income over several years.
- Overlooking early exit penalties, which can reduce the sum returned if the money is needed sooner than planned.
Questions
