What is an ETF?

An ETF (exchange-traded fund) is a basket of assets — usually shares in hundreds of companies — that trades on a stock exchange like a single stock. A broad market ETF like one tracking the S&P 500 or ASX 200 gives you instant diversification across the whole market. ETFs are designed for growth over the long term, and historically the share market has returned around 7–10% per year on average. That return comes with volatility — your balance will fall in bad years and recover over time.

What are bonds?

A bond is essentially a loan you make to a government or company. In return, they pay you a fixed interest rate (the "coupon") over a set period, then return your principal at maturity. Government bonds (like US Treasuries or Australian government bonds) are considered very safe — they pay predictably but offer lower returns. Corporate bonds pay more but carry higher default risk. You can also buy bond ETFs, which hold dozens of bonds and trade on the stock exchange like a regular ETF.

Growth comparison: $10,000 invested

Timeframe	ETF @ 8%	Bonds @ 3.5%
5 years	~$14,700	~$11,900
10 years	~$21,600	~$14,100
20 years	~$46,600	~$19,900
30 years	~$100,600	~$28,100

Over 30 years, the ETF grows to more than 3x the bond value. That gap is compounding doing its work — but bonds were never meant to compete on growth.

When bonds make sense

You're near or in retirement — preserving capital matters more than growing it.
You need predictable income — fixed coupon payments are reliable in a way dividends aren't.
You want to reduce portfolio volatility — bonds often move opposite to shares in a downturn.
You have a short time horizon — you can't afford to wait out a market crash.

When ETFs make sense

You have 10+ years before you need the money — time smooths out market volatility.
You're building wealth — compounding at 8% vs 3.5% is a massive difference over decades.
You want low-cost diversification — one ETF can hold hundreds of companies for minimal fees.
You can stomach short-term drops — ETFs can fall 20–40% in a downturn before recovering.

The classic approach: use both

Most long-term investors hold a mix of ETFs and bonds. A common rule of thumb is to hold your age as a percentage in bonds — so a 30-year-old holds 30% bonds, 70% ETFs. As you age, you gradually shift toward more bonds to protect what you've built. This isn't a fixed rule, but it captures the core idea: ETFs grow your wealth, bonds protect it.

FAQ

Are bonds safer than ETFs?

Generally yes — government bonds in particular are considered very low risk. But "safe" depends on your goal. Bonds are safe from short-term volatility but may not grow enough to outpace inflation over the long term.

Can I buy bond ETFs instead of individual bonds?

Yes, and for most retail investors this is the more practical option. Bond ETFs hold a diversified mix of bonds and trade on the stock exchange. They're much more accessible than buying individual bonds directly.

Do bonds pay dividends?

Not dividends — bonds pay interest (called a coupon). Bond ETFs pass this income through to investors, usually quarterly or monthly.

What happens to bonds when interest rates rise?

Bond prices fall when interest rates rise. This is one of the key risks of holding bonds — if rates increase, the market value of your existing bonds goes down. This affects bond ETFs too.

Is this relevant to Australian investors?

Yes. Australian investors can access both share ETFs (like those tracking the ASX 200) and bond ETFs through the ASX. Australian government bonds work the same way as described here.
