Australia Rolls Out Major Long-Term Bond Offering

The Australian Office of Financial Management (AOFM) — the government’s sovereign debt manager — has launched a new benchmark Treasury bond with an 11-year maturity, aiming to raise significant funding at the time of writing. This bond, set to mature on 21 October 2037, marks one of the most closely watched government debt issuances in the country’s recent financing calendar. While the exact size of the offering has not been publicly disclosed, strong demand has already been evident. Joint lead managers Barrenjoey Markets Pty Ltd, National Australia Bank Limited, UBS AG (Australia Branch) and Westpac Banking Corporation have collectively gathered over A$42 billion worth of orders — underscoring investor appetite for high-quality, long-dated government securities even amid evolving global interest rate conditions.

Attractive Yield Terms & Triple-A Rating

The new bond carries a coupon rate of 4.75 per cent and is being marketed with a tight spread over benchmark futures, which translates into a yield in the range of approximately 4.845 per cent to 4.865 per cent, at the time of writing. These terms have appealed to institutional investors seeking stable, long-term returns. Importantly, the October 2037 issue has secured AAA credit ratings from all three major rating agencies, reflecting Australia’s strong sovereign creditworthiness and reinforcing confidence among global fixed-income buyers.

Why This Matters to Markets

Government bonds — particularly long-dated ones like this 11-year instrument — play a crucial role in pricing risk and anchoring interest rate expectations across financial markets. High demand for this issue suggests that investors remain comfortable holding Australian government debt, even as central banks globally navigate inflation and economic growth uncertainties.

This new issuance not only helps the Australian government manage its funding needs effectively but also provides an important benchmark for pricing corporate and state-government bonds in domestic and international markets.

Next Steps & Market Impact

The bond is scheduled to be priced on 21 January 2026, or at short notice, depending on market conditions, with settlement and trading to follow. As a core part of Australia’s debt issuance program, this benchmark issue will be closely watched by investors, economists and policymakers alike as an indicator of broader market sentiment and funding costs in the years ahead
