Crypto Mortgages – Seriously?

July 26, 2025

As we mentioned in a previous update, APRA has been reviewing the mortgage serviceability buffer.

The serviceability buffer is an extra margin added to a loan’s interest rate when a lender assesses your ability to repay. Currently set at 3 percentage points, it means if you’re applying for a loan with a 6% interest rate, the lender tests whether you could still afford repayments at 9%. This helps ensure borrowers can manage future rate increases or financial pressure.

Contrary to earlier indications, the regulator has this week confirmed it will keep the buffer unchanged at 3 percentage points, citing steady lending standards, low non-performing loans, and easing financial pressures.

Is this bad news for borrowers? That’s a hard question to answer. Australia’s conservative banking regulations did help save us from the full impact of the GFC.

In this week’s newsletter, we take a look at the role crypto currencies could play in the mortgage landscape over the coming years.

While still in it’s early days, cryptocurrency has the potential to revolutionise the way we buy homes and structure mortgages. As digital assets become more mainstream, the idea of integrating crypto into home loan products is gaining traction, particularly among tech-savvy borrowers and fintech lenders looking to innovate.

In the future, we could see crypto used as a form of collateral for home loans. Rather than selling Bitcoin or Ethereum to fund a deposit, borrowers might be able to lock their crypto in a smart contract, allowing them to borrow against its value while retaining ownership. Blockchain technology could also enable faster, more secure mortgage processing, cutting down settlement times and reducing fraud risks.

Pros of crypto-backed mortgages.

  • Faster approvals and settlements: Smart contracts and decentralised verification could streamline application and approval processes.
  • Access to alternative wealth: Borrowers could leverage crypto holdings without converting them to fiat, avoiding tax events or market timing issues.
  • Greater innovation: New players in the lending space may offer competitive, flexible products tailored to digital asset holders.

However, there are notable challenges.

  • Volatility: Crypto values can swing wildly, posing significant risk to both borrowers and lenders if collateral suddenly drops in value.
  • Regulatory uncertainty: With evolving rules around digital assets, lenders may face legal and compliance hurdles.
  • Limited mainstream acceptance: Traditional banks are still hesitant to accept crypto due to risk concerns and lack of standardisation.

For now, crypto-backed mortgages remain a niche offering, but as technology matures and regulation catches up, they could become part of a broader ecosystem of mortgage products. Like any financial innovation, the key will be balancing opportunity with risk, and ensuring borrowers fully understand what they’re getting into.

While we’re not quite there yet, the idea of buying a home using crypto could be less science fiction and more reality in the not-too-distant future.
