Why Higher Interest Rates are the Best Thing to Ever Happen to Your Mortgage

Why Higher Interest Rates are the Best Thing to Ever Happen to Your Mortgage

The headlines are screaming bloody murder because the Reserve Bank of Australia (RBA) nudged the cash rate to 4.35%. They call it a "blow" to mortgage holders. They call it a "crushing weight" on the Australian dream.

They are wrong.

The media’s obsession with the monthly repayment figure is a shallow, mathematically illiterate distraction. If you are a mortgage holder, or someone desperately trying to become one, a 4.35% cash rate isn't your enemy. It is the only thing standing between you and a lifetime of debt slavery fueled by runaway asset inflation.

The "lazy consensus" suggests that low rates are a gift to the middle class. In reality, the decade of near-zero interest rates we just endured was a systematic transfer of wealth from the productive young to the unproductive asset-rich. By crying over a 25-basis point hike, the pundits are effectively arguing for the continued destruction of the Australian dollar's purchasing power.

The Cheap Money Trap

Let’s look at the mechanics. When interest rates are floor-level, your "affordability" doesn't actually improve. Why? Because everyone else has the same cheap credit.

Imagine a scenario where every person at a housing auction is handed an extra $200,000 in borrowing capacity by the bank. Does the house become more affordable? No. The price of the house simply rises by $200,000. You aren't buying more house; you are just taking on a larger debt to buy the same pile of bricks.

Low rates are a steroid for prices. High rates are the sobering reality check that forces sellers to confront the fact that their fibro-shack in the suburbs isn't actually worth two million dollars. For a decade, we have been valuing property based on "repayment capacity" rather than intrinsic value. That is a dangerous, fragile way to run an economy.

The Myth of the "Squeezed" Homeowner

The narrative focuses on the "mortgage prison." We are told that families are skipping meals to pay the bank. While the transition is painful, it ignores the basic economic principle of the Real Interest Rate.

The real interest rate is the nominal rate minus inflation ($r = i - \pi$).

If the RBA keeps rates at 1% while inflation is running at 7%, the real interest rate is -6%. This means the bank is effectively paying you to borrow money. This sounds great until you realize that in such an environment, the cost of everything else—food, fuel, electricity—is compounding faster than your wages.

By raising the cash rate to 4.35%, the RBA is attempting to bring the real interest rate back into positive territory. This is the "bitter medicine" required to stop your grocery bill from doubling every few years. If you think an extra $200 a month on your mortgage is bad, wait until you see what happens to a society where the currency loses its function as a store of value.

Why Savers Have Been Subsidizing Your Lifestyle

For fifteen years, the Australian economy has been a giant machine designed to punish people who save and reward people who gamble on property.

Retirees living on fixed incomes and young people trying to scrape together a deposit have been the invisible victims of the low-rate era. Their savings have been eroded by inflation while the RBA held rates at emergency levels long after the emergency had passed.

A 4.35% cash rate restores some semblance of moral hazard. It reminds investors that debt has a cost. It encourages capital to flow toward productive businesses—companies that actually make things and hire people—rather than just being recycled into an unproductive housing bubble.

The Correction is the Cure

The loudest critics of the RBA are those with the most to lose: highly leveraged developers and "rent-seeker" investors who built portfolios on the assumption that money would be free forever.

They claim that higher rates will crash the economy. This is a classic scare tactic. What they actually mean is that higher rates will crash their specific business model of infinite leverage.

A healthy economy requires "creative destruction." Some businesses should fail. Some over-leveraged speculators should be forced to sell. This clears the ground for new, more efficient players to enter the market. When you keep rates at 0.1%, you create "zombie" companies and "zombie" households that only exist because they don't have to pay the true cost of their capital.

Stop Asking if Rates Will Fall

The most common question I see is: "When will the RBA cut rates back to 2%?"

This is the wrong question. The right question is: "Why did we ever think 0.1% was normal?"

The historical average for interest rates in Australia is significantly higher than where we are now. The period from 2012 to 2022 was an anomaly—a global experiment in monetary insanity that has distorted our sense of value.

If you are waiting for a return to 2% rates to "fix" your finances, you aren't planning; you are wishing. You are better off using this period of higher rates to deleverage. The smartest move right now isn't to hope for a rate cut, but to realize that a 4% or 5% rate environment is the "new old normal."

The Brutal Truth About Housing Affordability

If you actually care about young Australians owning homes, you should be cheering for 6% interest rates.

High rates put a ceiling on how much debt people can carry. This eventually drags down the principal price of assets. It is far better to buy a $500,000 house at a 7% interest rate than a $1,000,000 house at a 2% interest rate.

Why? Because you can always refinance a high interest rate later, but you can never "refinance" a massive principal. Once you owe the bank a million dollars, you owe it until it's paid or you go bust.

The RBA isn't "blowing up" the dreams of mortgage holders. It is finally, belatedly, starting to let the air out of a bubble that was threatening to swallow the entire country's future.

Stop looking at your monthly statement and start looking at the health of the currency in your pocket. The RBA didn't hike rates to hurt you; they did it because the alternative—hyper-inflated asset prices and a dying dollar—is a much darker path.

The pain of a 4.35% rate is the price of admission for a functioning economy. Pay it.
