The Fixed-Rate Expiry Tsunami in 2026
In 2026, Australia is navigating the tail end of the largest fixed-rate expiry event in history. According to RBA data, roughly 880,000 fixed-rate loans are scheduled to expire in 2026, with the bulk concentrated in the first half of the year. Approximately 23% of all fixed-rate loans written during the pandemic-era low-rate period (2020–2021) are maturing this quarter alone.
The core problem is the staggering rate differential. Borrowers locking in 2- to 3-year terms in 2023/2024 at rates around 5.50%–5.90% are now facing a market where the standard variable rate (SVR) for major banks sits at an average of 7.34% (May 2026). That represents a worst-case jump of over 180 basis points overnight if no action is taken.
The Cost of Inaction: By the Numbers
Assuming a $500,000 mortgage balance over a 25-year remaining term:
- Auto Roll-off (Major Bank SVR): 7.34% · $3,620 · +$3,900
- Negotiated Basic Variable: 5.89% · $3,190 · $0 (Baseline)
- New 3-Year Fixed Rate: 5.59% · $3,095 · -$1,140 (in year one)
- Sharp Refinance Offer (Low LVR): 5.79% · $3,160 · -$360
Data sources: RBA Indicator Rates May 2026; Major bank published SVRs. Based on Owner-Occupied P&I loans <80% LVR.
The math is clear: staying on the automatic revert rate burns roughly $325 extra per month compared to simply asking your current bank for their best variable offer.
Path 1: Rolling to a Variable Rate (The Default Option)
If you take no action, your bank will typically move you to their headline Standard Variable Rate (SVR). This is almost always the uncompetitive ‘rack rate’. However, a variable loan is not inherently bad—the product features are often superior to fixed loans.
Pros of Variable (Post-Fixed):
- Full Offset Access: Unlike most fixed-rate loans where offset is partial or capped, variable loans usually allow 100% offset accounts, reducing your non-tax-deductible interest efficiently.
- No Break Costs: You can exit or refinance at any time without paying crippling Economic Cost break fees. If the RBA cuts the cash rate by 50 basis points in the next 12 months—as some analysts predict—you capture the benefit immediately.
- Flexibility: Unlimited extra repayments are standard, allowing you to get ahead on the principal.
The Critical Step: Rate Negotiation You rarely need to leave your bank to get a competitive variable rate. Retention teams have significant pricing discretion in 2026. Ask for a ‘Rate Review’ and cite the sharp market rates (currently 5.89% – 6.09% for sub-80% LVR). If they refuse to drop below, say, 6.50%, that’s a signal to refinance.
Path 2: Re-Fixing Your Home Loan
If your household budget can’t stomach uncertainty, re-fixing a portion or the entirety of your loan is viable. As of May 2026, 3-year fixed rates are sitting in the 5.45% – 5.79% range, which is actually cheaper than the average variable rate on offer.
The Yield Curve Inversion Play Currently, 2- and 3-year fixed rates are priced below average standard variable rates (5.59% fixed vs 5.89% variable). This suggests bond markets are pricing in RBA cuts. Re-fixing locks in a ‘below variable’ rate today, but you bet against aggressive rate cuts materializing.
The Break Cost Trap Warning: if you sell the property, refinance, or win the lottery and want to pay off the loan during the fixed period, break costs can be substantial. In a falling-rate environment, break costs spike because the bank’s loss on your contract increases.
The Splitting Strategy A popular 2026 tactic is the 50/50 split: fix half your loan for 3 years to secure baseline repayment certainty, and leave the other half on a variable rate with a 100% offset account. This gives you a hedge against both rate rises (fixed half is safe) and rate cuts (variable half benefits).
Q: How are break costs calculated if I break a fixed loan early?
Break costs are calculated using the difference between your contracted fixed rate and the current market swap rate for the remaining term, multiplied by the outstanding balance and remaining time. If market rates have fallen since you fixed, the differential (and thus the break cost) widens, potentially reaching $10,000+ on large loans.
Path 3: External Refinancing (Walking Down the Street)
Refinancing involves moving your loan to a new lender. The Australian Competition and Consumer Commission (ACCC) data shows that borrowers who switch lenders save an average of 0.40%–0.70% more than those who stay and negotiate.
The 2026 Refinance Viability Checklist:
- Loan-to-Value Ratio (LVR): Your must-have is usually an LVR below 80%. If your property value dipped (unlikely in 2026 given CoreLogic’s current 3.4% annualized growth forecast), you might cop Lenders Mortgage Insurance (LMI). Get a professional valuation, not just a bank desktop val.
- Serviceability Buffer: APRA mandates a 3.0% serviceability buffer (May 2026). You must prove you can afford repayments at your actual rate + 3.0%. If your income dropped during the fixed period (maternity leave, reduced overtime), you might be ‘mortgage trapped’ even if the new rate is lower.
- Discharge Timelines: The old bank needs a Discharge Authority (DSA). This takes 2–4 weeks. You must time this so the fixed term breaks after the maturity date to avoid break costs, but the settlement happens before you spend too long on the high revert rate.
Q: What is a ‘mortgage prisoner’ and am I at risk?
A ‘mortgage prisoner’ is a borrower who cannot refinance because their income or equity no longer meets APRA’s 3.0% serviceability buffer, despite being able to comfortably pay their current (often high) rate. If you’ve had a child, moved to part-time work, or taken parental leave during your fixed term, get a broker to assess your borrowing power before assuming you can move.
Avoiding the Cliff: Your 60-Day Action Plan
The worst outcome is spending a single day on the automatic revert rate.
Day 60-45 (Research & Valuation):
- Check your expiry letter. Note the exact date the fixed term ends.
- Order a free property valuation estimate (CoreLogic/RP Data) to check your LVR.
- Look up your current bank’s SVR and their ‘new customer’ basic variable rate. This gap is your negotiation leverage.
Day 45-30 (Negotiation & Application):
- Call your current lender’s retention team. Request a ‘Pricing Request’ to match the new customer rate.
- Simultaneously, submit a refinance application with a new lender offering a sharp rate. This runs in parallel.
Day 30-7 (Settlement & Discharge):
- Sign the new contract or accept the retention deal.
- If refinancing, sign the DSA form. The payout figure your new bank requests from the old bank will include a small amount of interest at the high revert rate if timing isn’t perfect—this is acceptable for 1-2 days.
Q: Can I fix my mortgage forever or for 10 years?
While some smaller lenders offer 7- or 10-year fixed terms, they are rare and expensive (often >6.50% as of May 2026). The standard long-term product is a 5-year fixed rate, typically used for investment properties where absolute cashflow certainty is required. For owner-occupiers, a 3-year fixed term is the sweet spot for balancing rate security and long-term flexibility.
Key Data: Where Rates Stand in May 2026
To make an informed decision, you need current market benchmarks:
- Variable (Low-Risk, <70% LVR): 5.89% - 6.09% · Flexibility, offset use, future rate cuts
- 1-Year Fixed: 5.99% - 6.29% · Short-term bridging
- 3-Year Fixed: 5.45% - 5.79% · Repayment certainty, budget management
- 5-Year Fixed: 5.65% - 5.99% · Long-term holding costs
- Major Bank SVR (Revert Rate): 7.15% - 7.54% · N/A – Avoid this

The Cash Rate Factor The RBA cash rate is currently at 4.10% (May 2026). The market is pricing in a 25bp cut by Q3 2026 and a further 25bp by early 2027. If you believe these cuts will happen, a partial variable strategy lets you capture the cuts. If you fear sticky service inflation keeping rates high, lock in the 3-year fixed rate now while it’s below 5.80%.
Q: Is there a ‘best’ time of year to roll off a fixed rate?
There’s no seasonal ‘best time’, but timing against RBA meetings matters. If your fixed term ends right after a suspected RBA cut, the variable rates on offer may be lower. Conversely, if the RBA just hiked, you might want to quickly negotiate a fixed rate before lenders absorb the increase into their fixed-rate pricing.
Documents You Need to Refinance in 2026
Lenders have tightened verification since the ‘Liar Loans’ era. Have these ready:
- Last 2 payslips and a group certificate/income statement.
- 3 months of bank statements (transaction accounts).
- Last 6 months of home loan statements (existing loan).
- Council rates notice (property details).
- Photo ID (Driver’s License or Passport).
Self-employed borrowers need the last 2 years of full financials and ATO Notices of Assessment. If your income structure changed (e.g., from sole trader to company), you might require a ‘Low Doc’ or ‘Alt Doc’ loan, which carries a premium rate of 0.5%–1.0%.
