When central banks want to influence the economy, they typically adjust interest rates. But when those rates are already low or traditional tools seem less effective, policymakers sometimes turn to less conventional methods. One such approach was Operation Twist—a strategy used by the US Federal Reserve to shape borrowing costs and support economic growth. As Australia continues to navigate global uncertainty and considers its own monetary policy options, understanding Operation Twist can offer valuable lessons for the years ahead.

What Was Operation Twist?
Operation Twist was first introduced by the US Federal Reserve in 1961 and later revived in 2011–2012, following the global financial crisis. Rather than simply lowering or raising the cash rate, the Fed sold short-term government securities and used the proceeds to purchase longer-term ones. This approach aimed to "twist" the yield curve—lowering long-term interest rates while keeping short-term rates steady or slightly higher.
Key objectives of Operation Twist:
- Lower long-term borrowing costs to encourage investment and home buying
- Avoid increasing the overall supply of money in the economy
- Influence expectations and confidence in financial markets
Unlike quantitative easing (QE), which involves buying bonds across different maturities and increasing the central bank’s balance sheet, Operation Twist was designed to be more targeted. By focusing on the composition of assets rather than their total amount, the Fed hoped to support economic activity without adding extra liquidity to the system.
Why Is Operation Twist Relevant for Australia?
Australia’s Reserve Bank (RBA) has traditionally relied on adjusting the cash rate to influence lending, spending, and inflation. However, with interest rates reaching historic lows in recent years, the RBA has explored other tools, such as yield curve control (YCC) and limited quantitative easing. As global economic conditions remain uncertain, there is renewed interest in alternative strategies that could help manage borrowing costs and support growth.
Potential Impacts on Australians
-
Housing affordability: Lower long-term interest rates can make mortgages more accessible, potentially easing the burden for home buyers. By targeting the long end of the yield curve, a policy similar to Operation Twist could help keep mortgage rates lower than they might otherwise be.
-
Business investment: Cheaper long-term borrowing costs can encourage businesses to invest in new projects, equipment, and expansion. This can support productivity and job creation, especially during periods of economic recovery or transition.
-
Superannuation and savings: While lower long-term yields can benefit borrowers, they may also reduce returns for savers and retirees. Superannuation funds, which often invest in long-term government bonds, could see lower income from these assets, making diversification and risk management even more important.
With the RBA reviewing its policy toolkit and the government considering how best to support economic resilience, the targeted approach of Operation Twist may become more relevant—particularly if traditional rate changes have less impact in the future.
Lessons from the US Experience
Operation Twist’s effectiveness in the US has been the subject of ongoing debate. Research suggests that the policy helped lower long-term Treasury yields, making mortgages and business loans more affordable. However, its broader impact on economic growth was less clear, as much depended on market expectations and overall confidence.
What Australia Can Take Away
-
Clear communication: The success of unconventional policies often depends on how they are explained to the public and financial markets. If the RBA were to consider a similar approach, transparent communication would be essential to avoid confusion and maintain confidence.
-
Market size and liquidity: Australia’s government bond market is smaller than that of the US. Large-scale buying and selling of bonds could lead to increased volatility or unintended consequences. Policymakers would need to carefully assess the capacity of local markets to absorb such operations.
-
Managing risks: Targeted bond operations can influence borrowing costs, but they also carry risks. These include potential distortions in credit markets and impacts on financial stability. Any move to adopt a twist-like policy would need to balance these risks against the potential benefits for borrowers and the broader economy.
Operation Twist and Australia’s Future Policy Options
As Australia looks ahead to 2026 and beyond, the economic landscape remains uncertain. The country faces challenges such as post-pandemic recovery, shifts in global trade, and the ongoing transition to a low-carbon economy. In this context, having a flexible set of policy tools is important.
Operation Twist demonstrates that central banks are not limited to adjusting the cash rate. By targeting specific parts of the yield curve, policymakers can influence borrowing costs in more nuanced ways. For Australia, this could mean having additional options to support growth and stability if traditional measures become less effective.
However, any consideration of such strategies must take into account the unique features of the Australian economy and financial system. Policymakers would need to weigh the potential benefits for home buyers and businesses against the possible impacts on savers, retirees, and market stability.
Conclusion: A Tool for Uncertain Times
Operation Twist remains a notable example of central bank innovation. While its results in the US were mixed, the policy offers important lessons for countries like Australia that may face similar challenges in the future. As the RBA continues to review its approach and adapt to changing conditions, the experience of Operation Twist highlights the value of flexibility, clear communication, and careful risk management in monetary policy.
For Australians, understanding these options can help make sense of how economic decisions affect everything from mortgage rates to superannuation returns. As the policy debate evolves, expect ongoing discussion about how best to support growth, manage inflation, and maintain financial stability in a changing world.
