Two Hands on the Brake

Series note: Commentary on how decisions are made, who makes them, and what they actually produce.

By Aiden Garrison

Let me put the facts on the table first, because the argument is built on them.

The Reserve Bank has raised the cash rate three times this year. It now sits at 4.35%.

The government has legislated the most significant changes to property taxation in a generation. The Treasury Laws Amendment passed the Senate in June. From July 2027, the 50% capital gains tax discount is replaced with an indexation model and a minimum tax. Negative gearing on established residential property is restricted to new builds for anything acquired after May 2026.

Inflation has been running around 4%, above the target band.

Unemployment has risen to 4.5%. Quarterly growth has slowed to a crawl. Productivity is going backwards. Household and business sentiment is weak.

And auction clearance rates have fallen sharply — well below where they sat a year ago, down more than twenty points year-on-year in some capitals.

Those are the numbers. Here's what I think they add up to.

Let me be clear about something before I go further.

This isn't an argument about whether reforming negative gearing and the capital gains tax discount is good policy or bad policy. There are serious, credible people on both sides of that question. I'm not writing about the merits.

I'm writing about the timing. And the combined effect.

Because whatever you think of the reforms themselves, two separate arms of economic policy are pressing on the brake at the same time, on an economy that was already slowing down. And I don't think enough people are talking about what that combination produces.

Start with monetary policy.

The RBA raised rates to fight inflation. That inflation wasn't one thing — it reflected higher energy prices flowing out of the Middle East conflict, but also domestic services inflation, insurance costs, housing costs, and broader price pressures that had been building for a while. The RBA responded the only way its mandate allows. It tightened.

Now add fiscal and structural policy.

The property tax changes are, in their effect, also contractionary. Whatever the intent, restricting negative gearing and reducing the capital gains discount takes some heat out of investment demand. That's part of the point of them. I'm not arguing the rights and wrongs. I'm pointing at the calendar.

Monetary policy is contractionary right now. Property tax policy just became contractionary too. Both are landing together.

And the economy they're landing on was already cooling before either fully bit. This isn't an economy running hot that needs restraining. It's one already losing momentum on its own.

You can see the effect arriving in the market these policies touch most directly. Housing analysts broadly attribute much of the recent weakness in clearance rates to higher interest rates and the property tax changes, alongside the usual mid-year slowdown and broader economic conditions. Not one cause. But those two are named again and again.

Two hands on the brake. And the car was already slowing.

Here's the part that concerns me most, and it has nothing to do with whether the reforms are justified.

Monetary policy works with a lag. It takes twelve to eighteen months for a rate rise to move fully through the economy. So the three rises already delivered this year haven't shown their full effect yet. That braking force is still in the post.

Tax policy works on a different clock, but it works early. Behaviour starts shifting the moment changes are announced, well before they commence. Expectations move markets before legislation ever takes effect. Investors reprice risk, bring forward or delay decisions, and adjust plans the day the intent becomes clear — not the day the law starts.

So we have two contractionary forces, on two different timelines, both only partly felt, both compounding, hitting an economy that was already decelerating.

My honest read — and it is a read, not a certainty — is that this is more restraint than the economy can comfortably absorb at this particular moment. Not because either policy is wrong in isolation. Because the combined dose, at this timing, into this level of momentum, risks overshooting. By the time the full lagged weight of both lands, we may find we've cooled things more than anyone intended.

I could be wrong. The inflation genuinely needed addressing, and letting it embed would have been worse. Reasonable people may disagree and say the economy is more resilient than I'm giving it credit for. That's a fair challenge and I'll hold it honestly.

But this is where the interesting question sits. And it isn't about the reforms at all.

Think about how the institutions are actually built.

The Reserve Bank has a clear mandate — control inflation, support employment. It moves the cash rate to do that. It is not asked to account for fiscal policy.

Treasury designs taxation. It builds the settings it believes are right for the revenue base and the housing market. It is not asked to time those settings around the interest rate cycle.

Cabinet pursues housing and social policy. It legislates what it went to the people to do. It is not asked to measure the monetary consequences.

Each of those institutions is doing its job. Each is acting rationally and defensibly within its own lane. None of them is responsible for measuring the combined contractionary effect of every policy pressing at once.

That's the gap. No single hand is measuring the total force of both brakes pressed together. Nobody owns the sum.

And that's not a policy failure in the usual sense. It's a coordination gap. Coordination gaps are exactly where economies get hurt — not through one bad decision, but through the sum of several reasonable ones that nobody added up.

The Reserve Bank is doing its job.

The government is doing its job.

The concern isn't that either is wrong. It's that nobody owns the combined effect.

Economies are rarely damaged by a single bad decision. More often they're damaged by several reasonable decisions, each defensible on its own, whose combined weight exceeds anything anyone intended.

That's the thing worth watching. Not whether any one policy is right.

Whether anyone is adding them up.
