How to protect your nest egg in a world of rising inflation

Last Easter I wrote a piece for Money reminding investors not to put all their eggs in one basket. This year shows why diversification matters more than ever.

It was almost 12 months ago that the Liberation Day tariffs triggered a sharp sell-off in Australian and global share markets. Since then, we've seen a strong rebound in equities, record highs for gold and silver, and no shortage of geopolitical shocks.

Now, investors are once again facing volatility. Ongoing conflict in the Middle East has pushed oil prices sharply higher, reigniting inflation fears just as many hoped cost-of-living pressures were easing. The big question this Easter is how to protect your nest egg from cracking and ensure your portfolio is built to handle inflationary and rising interest rate pressures.

Why are interest rates rising again

The Reserve Bank of Australia is walking a tightrope. Inflation remains above its comfort zone, the job market is still relatively tight, and policymakers have been clear that bringing prices under control is their top priority. Even if that slows economic growth.

Recent oil price shocks have made the RBA's job harder. Transport makes up a relevant share of Australia's inflation basket, so higher fuel prices quickly flow through to everyday costs. That's one reason markets have shifted from expecting rate cuts to pricing in further hikes.

The message for investors is simple: interest rates may stay higher for longer, and portfolios need to be able to cope with that reality.

A focus on energy and materials

Higher interest rates don't mean shares are off the table. They do, however, change which types of companies tend to perform better.

In rising rate environments, the market often favours businesses with strong cash flows and pricing power. These types of businesses are generally better positioned to protect their profits when inflation sticks around.

Energy and materials companies are a good example. Commodity producers often benefit from higher prices, and the Australian share market already has strong exposure to these sectors. Historically, they have tended to outperform during inflationary periods.

On the flip side, sectors like technology and property (including REITs) can struggle when interest rates rise. Higher rates reduce the value of future earnings, which can pressure valuations. Consumer discretionary shares may also feel the pinch as households adjust to larger mortgage repayments and rising rents.

Rethinking income beyond bank dividends

Generating reliable income has become harder. Dividend yields across the Australian market have fallen over recent years, and relying solely on traditional dividends may no longer be enough to keep up with the cost of living.

One approach is to be more selective by focusing on higher-yielding companies while still maintaining diversification. The goal is not to chase the highest yield at any cost, but to find sustainable income streams with sensible risk.

Some investors are also turning to covered call strategies. In simple terms, these strategies involve generating extra income by selling options over share portfolios. During volatile markets option premiums tend to be higher, which can boost income and help smooth returns when markets move sideways or fall.

Fixed income: floating instead of fixed

Traditional fixed-rate bonds usually struggle when interest rates rise, because newer bonds offer better yields, pushing down the value of older ones.

Floating-rate bonds work differently. Their income payments reset as interest rates move higher, which can make them more resilient in a rising rate environment. For income-focused investors, this can mean steadier returns with less price volatility.

Including floating-rate exposure alongside traditional bonds can help balance a portfolio as rates change.

Commodities as protection against inflation

Commodities aren't a direct interest rate play, but they are closely tied to inflation.

During periods of high inflation and slowing growth, real assets like commodities and gold have historically helped protect purchasing power. They're not about quick gains, but about diversification and resilience when traditional assets face pressure. Commodities are the insurance you hope won't perform, but glad you have them when you need it most.

Broad commodity exposure or targeted precious metals allocations can both play a role, depending on an investor's goals and risk tolerance.

Don't overlook global diversification

Australia isn't moving in lockstep with the rest of the world. While the RBA is tightening, other major economies are further along the cycle or already easing.

Investing globally helps spread risk and reduces reliance on local economic conditions. It also provides access to long-term growth themes like artificial intelligence, renewables and automation, that exist regardless of where interest rates sit in the short term.

Currency movements matter too. Higher Australian rates can support the dollar, which may reduce returns from unhedged offshore investments. For this reason, many investors are increasingly considering currency-hedged options.

Staying steady through uncertainty

Rising interest rates don't require drastic changes or panic selling. They do, however, reinforce the importance of diversification, flexibility and discipline.

Markets move in cycles, and volatility comes and goes. The most resilient portfolios are built to weather all conditions.

This Easter, protecting your nest egg is less about finding the biggest chocolate egg, and more about making sure your basket is well-balanced enough to enjoy the whole hunt, whatever the market brings.
