Moral Suasion in Australia: How the RBA Uses Influence in 2025

When the Reserve Bank of Australia (RBA) speaks, markets listen. But what happens when the RBA chooses gentle nudges over blunt instruments? Welcome to the world of moral suasion—a powerful, often overlooked tool in the central bank’s arsenal. In 2025, as Australia navigates economic uncertainty and shifting global headwinds, understanding this concept is more relevant than ever.

What Is Moral Suasion? The Soft Power of Central Banking

Moral suasion refers to the efforts by central banks or governments to influence the behaviour of banks, financial institutions, and sometimes even the broader public, not through mandates or regulatory changes, but through persuasion, guidance, and public statements. Think of it as policy by press conference or backroom conversation, rather than policy by decree.

Unlike official interest rate changes or macroprudential rules, moral suasion relies on credibility, reputation, and the subtle threat of future regulation. In the Australian context, this can look like:

• RBA officials hinting that lenders should pass on cash rate cuts to borrowers.
• Behind-the-scenes conversations urging banks to tighten lending standards in frothy housing markets.
• Public speeches or reports highlighting risks in certain sectors, prompting institutions to self-correct.

This method is not legally binding, but in a tightly knit financial system like Australia’s, it can be remarkably effective.

Recent Examples: Moral Suasion in Action (2024–2025)

The last 18 months have been a masterclass in central bank communication. With inflation proving sticky and mortgage stress on the rise, the RBA has leaned heavily on moral suasion rather than blunt-force regulation. Here’s how it’s played out:

• Housing Market Cool-Down: In late 2024, as property prices rebounded, the RBA publicly flagged concerns about speculative lending. Major lenders responded by tweaking their serviceability buffers and pulling back on high-risk investor loans—without any formal regulatory change.
• Interest Rate Transmission: As the RBA held the cash rate steady through early 2025, Governor Michele Bullock made clear in speeches that banks were expected to pass on lower funding costs to consumers. Most lenders adjusted variable mortgage rates accordingly, wary of public and regulatory scrutiny.
• Climate Risk Disclosure: In 2025, the RBA and APRA jointly reminded banks of their obligations to manage climate-related financial risks. The ‘reminder’ led to a wave of enhanced disclosure and divestment from high-emission sectors—even before any new rules were finalised.

In each case, the message was clear: act voluntarily, or prepare for a heavier regulatory hand.

Why Moral Suasion Matters in 2025

Australia’s financial system is facing a delicate balancing act—supporting growth without reigniting inflation, and promoting lending while avoiding asset bubbles. In this environment, moral suasion offers several advantages:

• Speed: Informal guidance can prompt faster responses than the slow machinery of regulation.
• Flexibility: The RBA can target specific risks (like buy-now-pay-later lending or regional housing booms) without blanket rules.
• Market Stability: By nudging behaviour rather than shocking the system, moral suasion can dampen volatility and maintain confidence.

However, its effectiveness depends on trust and the central bank’s reputation. If institutions sense empty threats, moral suasion loses its bite. That’s why the RBA’s messaging in 2025 is carefully calibrated, mixing encouragement with reminders that formal action is always an option.

Looking Ahead: The Limits and Future of Moral Suasion

As Australia’s economy evolves, so too will the RBA’s approach. Moral suasion is not a panacea. It works best when banks and markets believe the regulator has both the will and means to escalate if needed. In a more fragmented or less trusting financial environment, its power may wane.

Yet, for now, as policy uncertainty and global turbulence persist, expect the RBA’s soft power to remain a fixture. For financial professionals, borrowers, and investors alike, reading between the lines of central bank commentary has never been more important.
