Gilt-Edged Securities in Australia: 2025 Guide for Investors

In an era of volatile markets and shifting global economics, the search for stability is more relevant than ever. For Australian investors, gilt-edged securities—often simply called ‘gilts’—are regaining popularity as a cornerstone of safe, income-generating portfolios. But what exactly are gilt-edged securities, and how do they fit into the 2025 investment landscape?

What Are Gilt-Edged Securities?

Gilt-edged securities are high-grade bonds issued by governments or reputable institutions. The term ‘gilt’ originates from the UK, referencing the gold leaf that once adorned the certificates, but in Australia, it generally refers to Commonwealth Government Securities (CGS) and similar state-issued bonds. These are considered among the safest investments available because they are backed by the government’s promise to pay interest and return the principal at maturity.

• Low risk of default: Backed by government creditworthiness

• Regular income: Pay fixed or floating interest, usually semi-annually

• Highly liquid: Traded actively on the ASX and over-the-counter markets

In 2025, with the RBA keeping a watchful eye on inflation and global uncertainty, gilts are once again in the spotlight for cautious investors, retirees, and super funds.

How Gilt-Edged Securities Fit Into a 2025 Portfolio

The investment climate in 2025 is marked by higher global interest rates and inflation uncertainty. While equities and property markets remain attractive for growth, many Australians are looking to rebalance their portfolios with defensive assets. Here’s why gilts are drawing renewed attention:

• Rising Yields: The yield on 10-year Australian government bonds has climbed above 4% for the first time in a decade, making gilts more appealing relative to term deposits and cash.

• Inflation Protection: Inflation-linked gilts adjust their payouts with the CPI, helping investors maintain real purchasing power.

• Superannuation Changes: The 2025 federal budget introduced incentives for super funds to hold a higher proportion of defensive assets, including government bonds, to improve retirement outcomes.

For example, a retiree with a $500,000 portfolio could allocate $100,000 to a mix of nominal and inflation-linked gilts, locking in steady income and reducing exposure to equity market swings.

Accessing Gilts: Practical Options for Australians

Australian investors can access gilt-edged securities in several ways:

• Direct Purchase: Buy Commonwealth Government Securities on the ASX in $100 face-value parcels, with maturities ranging from 1 to 20 years.

• Bond ETFs: Exchange-traded funds like the iShares Core Composite Bond ETF (ASX: IAF) or Vanguard Australian Government Bond Index ETF (ASX: VGB) provide exposure to a diversified basket of gilts.

• Super Funds: Most major super funds offer a fixed interest or defensive option that includes a significant allocation to gilts.

New in 2025, the AOFM (Australian Office of Financial Management) expanded its green bond issuance program, allowing investors to support climate projects via government-backed, environmentally focused gilts—a trend expected to attract ESG-conscious Australians.

Risks and Considerations

While gilt-edged securities are low risk, they are not entirely risk-free. Rising interest rates can cause bond prices to fall, so investors should match their investment horizon to the bond’s maturity. Tax treatment of bond interest and capital gains is another factor to consider, especially for self-managed super funds and high-income earners.

Overall, gilts offer an attractive combination of safety, liquidity, and steady income—qualities in high demand as economic conditions remain uncertain in 2025.
