Interpreting an Equilibrium Return Estimate for Treasury Bills

Summary

The document asks what an estimated equilibrium return on 90-day Treasury bills means when it appears as the risk-free rate in a reference portfolio review. The accepted answer interprets the figure as a long-run estimate of the policy-rate environment, rather than as a current bill yield or a promised return. It notes that New Zealand has historically had higher interest rates than the United States, which can inform a higher long-run estimate for New Zealand.

The explanation is brief and gives no calculation, forecast framework, or supporting data. It also does not define how the report estimated equilibrium or distinguish the expected policy rate from the return on a specific Treasury bill. The main takeaway is contextual: a risk-free-rate assumption should be read in light of the relevant country’s long-run interest-rate setting. The answer alone is insufficient to judge the estimate’s accuracy or how it should be applied in portfolio construction.

Key ideas

• An equilibrium bill return is presented as a long-run rate estimate.
• The estimate reflects the country-specific policy-rate environment.
• Historically higher New Zealand rates can support a higher long-run assumption than in the United States.
• The document supplies no method for estimating or validating the figure.

I have been reading NZ Superfund's 2015 Ref Portfolio Review (here) and came across this notion:

> Our estimate of the equilibrium return on 90-day Treasury Bills is 5%.

And this is under the column Risk-Free Rate. Can anybody expalin what does this mean?

NZ has traditionally had rates higher than US.

As such, their very long run (or equilibrium) estimate of policy rates will likely be way above other developed markets.
