Hewson: RBA decisions serve public good under uncertainty

RBA Monetary Policy Board member Carolyn Hewson reflected on economic leadership and public responsibility at the Joseph Fisher Public Lecture. She discussed how the RBA's dual mandate guides decisions under uncertainty.

The dual mandate's public purpose

Carolyn Hewson highlighted Joseph Fisher's legacy, emphasizing that economics, at its best, serves the public good and informs policy.

She connected this to the Reserve Bank of Australia's (RBA) dual mandate, which charges the institution with supporting low and stable inflation alongside a high level of employment.

Hewson clarified that this pairing is not a compromise between competing goals but reflects a longstanding economic insight: prosperity is sustained by the interaction of price stability and employment outcomes.

Over the longer term, price stability enables households to plan and businesses to invest with confidence, fostering innovation and job creation.

The challenge arises in shorter periods when economic shocks disrupt this balance, making the achievement of both elements of the mandate more complex.

Hewson stressed that for policymakers, it is not a question of which objective matters more, but rather understanding their long-term complementarity.

Navigating policy under uncertainty

Hewson detailed the RBA's Monetary Policy Board's practical approach to decision-making under uncertainty, informed by disciplined briefings from RBA staff on economic analysis and financial market developments.

The Board closely monitors indicators like short-term interest rates, the yield curve, corporate bond spreads, equity markets, and the exchange rate to assess financial conditions and policy transmission.

Complementing official statistics, the RBA's extensive business and community liaison program provides crucial real-economy insights into hiring, investment, pricing, and confidence.

This comprehensive approach guides the Board in determining the appropriate monetary policy stance to achieve its mandate.

A timeless call for responsible governance

Hewson's speech robustly defends central bank independence and public purpose, framing the RBA's dual mandate as complementary.

Yet, it largely reiterates established principles, offering little in terms of new approaches to complex trade-offs.

The address thus serves more as a foundational statement than a roadmap for immediate policy challenges.
