You might have seen the headlines: Google’s parent company, Alphabet, has just raised A$5.5 billion from Australian investors by selling bonds.
That’s a pretty big deal. In fact, it’s the largest corporate bond issue Australia has ever seen, more than twice the previous record of A$2.25 billion set by Apple in 2015.
But why should an everyday investor care? Alphabet isn’t exactly a company short of cash. And if you’re investing for financial independence, there’s a good chance your portfolio is heavily weighted towards shares.
So this raises an interesting question: do bonds have a place in a long-term, FIRE-focused portfolio? Let’s take a look.
Why is Alphabet borrowing billions?
The answer, unsurprisingly, is AI. Alphabet is spending huge amounts of money building the infrastructure needed to compete in AI, from data centres and chips to the enormous amounts of energy required to run them.
The company has flagged capital expenditure of up to US$205 billion in 2026. At the same time, Alphabet reported negative free cash flow in the June quarter. So, rather than simply burning through its cash reserves, Alphabet is borrowing.
Its latest Australian-dollar bond, known as a Kangaroo bond, was split across six tranches with maturities ranging from three to 20 years. The 20-year tranche has a coupon of around 6.9%. And investors were very keen. Orders reportedly topped A$18 billion – more than three times the amount Alphabet was looking to raise.
Alphabet is far from the only tech giant turning to debt to fund the AI arms race. Kangaroo bond issuance in Australia has reportedly reached around A$60 billion in 2026, about 40% higher than the previous year.
For Alphabet, taking on debt isn’t necessarily a sign that something is wrong. It’s simply another way to fund a huge amount of spending without having to sell shares or run down its cash pile. And for investors, it provides a useful reminder that debt can play a very different role in a portfolio from shares.
So, what exactly is a bond?
The simplest way to think about a bond is as an IOU. When you buy a bond, you’re lending money to a government or company. In return, the issuer generally agrees to:
- Pay you interest: This is the bond’s coupon, usually paid regularly.
- Return your money: When the bond reaches maturity, you typically get the face value back, assuming the issuer doesn’t default.
- Give you a defined timeframe: Bonds generally have a set maturity, unlike shares, which you can theoretically hold indefinitely.
One thing that can trip people up is the difference between a bond’s coupon and yield. The coupon is the interest rate attached to the bond when it’s issued. The yield is what you can expect to earn based on the price you pay for the bond in the market. Because bond prices move, yields move too.
And, of course, bonds aren’t risk-free. A government bond from a highly creditworthy government is generally considered relatively low risk, while lending to a company comes with the possibility that the company won’t be able to repay you.
Do you actually need bonds in a FIRE portfolio?
This is where things can get interesting.
If you’re in the accumulation phase of your FIRE journey, it’s easy to see why you might favour shares. Equities have historically delivered higher returns than bonds over long periods. If you have decades before you need the money, you can potentially afford to sit through some pretty uncomfortable market downturns along the way. That’s one reason a 100% share portfolio can make sense for some investors.
But it doesn’t mean it’s the right portfolio for everyone, or that your asset allocation should stay exactly the same forever. Bonds can bring a few things to the table that shares can’t.
They can reduce portfolio volatility
When share markets have a nasty day, having some money in bonds can soften the blow. Government bonds in particular can sometimes perform well when investors are fleeing riskier assets. The relationship isn’t guaranteed, but the point is that you’re not relying entirely on one type of investment to do the heavy lifting.
They can provide income
Bonds pay interest, which can provide a relatively predictable income stream. That can become more useful as you get closer to financial independence. When you’re still decades away from FIRE, maximising long-term growth might be the priority. When you’re living off your portfolio, having some assets designed to produce income can become more appealing.
They can diversify your portfolio
The whole point of diversification is not putting all your eggs in one basket. That doesn’t necessarily mean owning a little bit of everything. But combining assets that behave differently can help reduce the impact of a big fall in one part of your portfolio.
We’ve previously looked at why diversification matters, and bonds can be one way of adding another source of diversification.
How can you buy bonds if you’re not Alphabet?
There’s a catch with all this. You probably can’t just jump onto your brokerage account and buy a piece of Alphabet’s new A$5.5 billion bond issue. Large corporate bond deals like this are generally aimed at institutional investors, super funds and wholesale clients, and can involve minimum investments far beyond what most everyday investors have available.
That’s where bond ETFs can be useful. Rather than buying a single bond from a single company, a bond ETF gives you exposure to a portfolio of bonds. Depending on the ETF, these might include government bonds, corporate bonds, Australian bonds, international bonds or a combination of different types.
They also trade on the ASX, just like share ETFs. For an everyday investor, that means you can get exposure to fixed income without needing hundreds of thousands of dollars to buy individual bonds.
There are a few other advantages, too:
- Diversification: You’re spreading your money across lots of different issuers rather than lending a large amount to one company.
- Accessibility: You can invest smaller amounts.
- Simplicity: The ETF takes care of managing the underlying bonds, so you don’t need to keep track of individual maturities and coupon payments.

So, do bonds deserve a spot in your portfolio?
Alphabet’s bond deal is ultimately a story about AI and the extraordinary amount of money being poured into building the infrastructure behind it. But it also gives us a reason to think about something much closer to home: what role should bonds play in our own portfolios?
There isn’t a magic percentage that works for everyone. If you’re young, investing for the long term and comfortable watching your portfolio fall sharply during a market crash, you might decide that a high allocation to shares makes sense. If you’re getting closer to financial independence, or simply don’t enjoy the volatility that comes with an equity-heavy portfolio, you might decide that adding some bonds is worth the trade-off.
The important thing isn’t finding the one “correct” allocation, but building a portfolio that matches your goals, your timeframe and your ability to stick with it when markets get ugly.
