What to check before you buy your first bonds and bond ETF

In 2022, a fund holding only US government bonds lost 31% in a single year. Here is how to choose a bond ETF that behaves the way you expect.

Ask most people what a bond ETF is for and they will tell you it is the safe part. The boring part. The money you do not worry about. Then show them 2022. That year, one of the most popular bond ETFs in the world, a fund holding nothing but long-term US government bonds, lost about 31%. Not a single bond in it defaulted. The US government paid every coupon on time. Investors who bought it as their safe option still lost almost a third of their money in twelve months.

Nothing was wrong with the fund. It did exactly what it was built to do. The problem was that most of the people holding it did not know what it was built to do.

What a bond ETF actually is

A bond ETF is a fund that holds a basket of bonds, loans to governments or companies that pay interest and return the money at a set date. Instead of buying individual bonds, which is expensive and complicated for a private investor, you buy one fund that holds hundreds or thousands of them. You can buy and sell it on a stock exchange like any other ETF.

The complexity comes from the fact that “bond ETF” covers funds that behave completely differently from one another.

The one number most people never look at

When interest rates rise, the value of existing bonds falls, because new bonds pay more. How much it falls depends on one figure: duration.

Duration tells you roughly how much a bond fund’s value moves when interest rates change by one percentage point. A fund with a duration of 2 loses about 2% if rates rise by one point. A fund with a duration of 17 loses about 17%.

That is exactly what happened in 2022. Short-term bond funds lost low single digits. Intermediate funds lost around 13%. Long-term government bond funds lost close to 30%. Same safe issuer, same year, wildly different outcomes. The only real difference was duration.

It works in reverse too. When rates fall, long-duration funds rise sharply. Neither outcome is good or bad in itself. What matters is whether you chose that level of risk on purpose.

Four choices that decide what you own

Who you lend to. Government bonds are the most stable. Investment-grade corporate bonds pay a little more for a little more risk. High-yield bonds pay considerably more because the companies behind them are more likely to fail, and in a crisis they tend to fall alongside shares, which is precisely when you want your bonds to hold up.

For how long. Short, intermediate or long duration, as above. This is the single biggest driver of how bumpy the ride will be.

In which currency. Your dirhams are pegged to the US dollar, so dollar bonds carry no currency risk while you live here. If your future is in euros or pounds, that changes the picture, and some funds offer currency-hedged versions that remove most of the exchange-rate swings for a small cost. The right answer depends on where you expect to spend the money.

Income paid out, or reinvested. Distributing funds pay you the interest in cash. Accumulating funds reinvest it automatically. One suits someone who needs income now, the other someone building savings for later.

The UAE question most guides skip

There is a fifth choice that matters more for UAE residents than for almost anyone else: where the fund itself is registered.

Many of the best-known bond ETFs are registered in the United States. For investors who are not US citizens or residents, holding US-registered funds above USD 60,000 can expose their estate to US estate tax, at rates of up to 40%. The same type of bond exposure is often available through funds registered in Ireland, which avoid that particular problem. Fund registration also affects how the income is taxed, and the rules for bond funds are not the same as for share funds.

None of this appears on a fund’s marketing page. It is the kind of detail that only becomes visible once you know to look for it.

What bonds are actually for

Bonds are not there to make you rich, shares do that, over the long run. Bonds are there to steady your portfolio when shares fall, to provide predictable income, and to hold money you will need within a few years.

The right bond ETF for you is the one whose behaviour matches that job. Money for a house deposit in two years needs something very different from the stable portion of a pension you will draw in twenty.

Before buying your first bond ETF, it is worth being able to answer three questions. What is this money for, and when will I need it? In which currency will I spend it? How large a fall could I sit through without selling? If you can answer those, choosing a fund becomes far simpler. If you cannot, no fund comparison will help.

See it done, step by step

At my ETF investing workshop we go through how ETFs are built, how to compare them, which fund structures make sense for UAE residents, and you watch the full buying process live inside a real brokerage account, so your first purchase feels straightforward rather than scary. You leave with a clear plan for how ETFs, bond ETFs included, fit into your own finances. This will be my last live workshop of 2026. Book your place here
