As we move through the final quarter of 2025, millions of Australian mortgage holders continue to face the reality of the "fixed rate cliff" – the transition from ultra-low pandemic-era fixed rates to current variable rates that can be 3-4% higher.
With some households experiencing monthly payment increases of up to $1,500, the importance of strategic refinancing and loan restructuring has never been greater.
Understanding the Fixed Rate Cliff Impact
The fixed rate cliff represents one of the most significant financial challenges facing Australian households since the Global Financial Crisis.
During 2020-2022, many borrowers secured fixed rates below 2%, with some as low as 1.89%. These rates are now expiring, forcing borrowers onto variable rates typically ranging from 5.5% to 6.5%.
According to industry analysis from Lendology, households rolling off ultra-low fixed rates are experiencing monthly payment increases that can reach $1,500 for larger mortgages.
For a typical $800,000 mortgage, the transition from a 1.9% fixed rate to a 5.8% variable rate represents an additional $2,496 per month in repayments.
The RBA's recent decision to hold rates at 3.6% provides some stability, but it doesn't address the fundamental challenge facing borrowers whose fixed terms are expiring at much higher rates than they originally secured.
The Refinancing Surge: Why It's Accelerating
Despite the RBA's pause on rate cuts, Australia is experiencing a continued surge in refinancing activity. This trend is being driven by several factors:
Rate Differential Opportunities:
While the cash rate remains elevated, competition among lenders has intensified. Non-bank lenders and smaller institutions are offering rates significantly below the major banks, creating opportunities for substantial savings.
Loyalty Tax Reality:
Major banks continue to reserve their best rates for new customers, meaning existing borrowers often pay a "loyalty tax" of 0.5-1% above competitive market rates. This differential becomes particularly painful when combined with fixed rate expiry.
Product Innovation:
Lenders are introducing more sophisticated loan products, including split loans, offset facilities, and flexible repayment options that weren't widely available when many borrowers first secured their mortgages.
Our Strategic Approach to Fixed Rate Cliff Management
At Shaper Finance, we've developed a comprehensive approach to helping clients navigate the fixed rate cliff that goes beyond simple rate comparison.
Our strategy focuses on three key areas:
1. Proactive Rate Review and Timing
Rather than waiting for fixed rates to expire, we work with clients to review their options 3-6 months before expiry. This provides time to secure competitive rates and avoid the rush that often occurs when rates are about to expire.
We've found that clients who plan ahead can often secure rates 0.2-0.4% lower than those who wait until the last minute, simply due to having more time to compare options and negotiate with lenders.
2. Loan Structure Optimisation
The fixed rate cliff presents an opportunity to reassess not just rates, but entire loan structures. We help clients consider:
- Split Loan Strategies: Combining fixed and variable portions to provide stability while maintaining flexibility for future rate movements
- Offset Account Maximisation: Structuring loans to take full advantage of offset facilities that can effectively reduce interest rates
- Repayment Flexibility: Ensuring loan features allow for extra repayments during good times and payment holidays if needed
3. Comprehensive Financial Health Assessment
The transition off fixed rates often reveals broader financial vulnerabilities. We conduct comprehensive assessments that consider:
- Emergency fund adequacy for rate volatility
- Insurance coverage for income protection
- Investment property portfolio optimisation
- Debt consolidation opportunities

Split Loan Strategy: Managing Future Rate Risk
One of the most effective strategies we're implementing for clients facing the fixed rate cliff is the split loan approach. This involves dividing your mortgage between fixed and variable portions, typically in ratios like 50/50, 60/40, or 70/30.
Benefits of Split Loans:
- Rate Protection: Fixed portion provides certainty against future rate rises
- Flexibility: Variable portion allows benefit from rate cuts and extra repayments
- Risk Management: Reduces exposure to both rising and falling rate scenarios
- Feature Access: Often allows access to offset accounts on variable portion
Current Market Positioning:
With the RBA signalling caution about future rate cuts, locking in some fixed rate protection at current levels (around 5.8-6.2% for 3-year terms) provides valuable insurance against potential rate increases while maintaining variable exposure for any future cuts.
Timing Your Refinancing Decision
The refinancing market in late 2025 presents unique timing considerations:
Immediate Action Indicators:
- Fixed rate expiring within 6 months
- Current rate more than 0.5% above market
- Limited loan features (no offset, restricted extra repayments)
- Considering property purchase or investment
Market Timing Factors:
- Lender competition remains intense through year-end
- New lending policies taking effect in 2026 may tighten criteria
- Property market activity creating urgency for pre-approvals
Beyond Rate: Evaluating Total Loan Value
While interest rates dominate refinancing discussions, our analysis shows that focusing solely on rates can miss significant value opportunities:
Fee Structures:
Annual fees, application costs, and ongoing charges can offset rate benefits. We evaluate total cost of ownership over 2-3 year periods to identify genuine savings.
Feature Benefits:
Offset accounts, redraw facilities, and repayment flexibility can provide value equivalent to 0.2-0.5% in rate reductions through improved cash flow management.
Service Quality:
Lender responsiveness, online platforms, and customer service quality become crucial during times of financial stress or when seeking loan modifications.
Taking Action: Your Refinancing Roadmap
If you're facing the fixed rate cliff or seeking to optimise your current mortgage, consider this strategic approach:
Phase 1: Assessment (Weeks 1-2)
- Review current loan terms and upcoming expiry dates
- Gather recent payslips, tax returns, and property valuations
- Calculate current repayments vs. market alternatives
Phase 2: Market Analysis (Weeks 3-4)
- Compare rates across multiple lender types (banks, non-banks, credit unions)
- Evaluate loan features and fee structures
- Consider split loan options for risk management
Phase 3: Application and Negotiation (Weeks 5-8)
- Submit applications to 2-3 preferred lenders
- Negotiate with current lender using competitive offers
- Finalise loan structure and settlement timing
Phase 4: Implementation (Weeks 9-12)
- Complete loan documentation and settlement
- Establish new banking relationships and online access
- Implement ongoing loan management strategies
The Bottom Line: Action Beats Inaction
The fixed rate cliff represents both a challenge and an opportunity. While payment increases are inevitable for many borrowers, the extent of that increase can be significantly influenced by proactive refinancing and loan restructuring.
Our analysis shows that borrowers who take strategic action can often reduce their payment shock by 40-60% compared to simply accepting their existing lender's standard variable rate. For many households, this represents savings of $500-1,500 per month.
The key is starting the process early, considering all available options, and structuring loans for both current affordability and future flexibility. With the right approach, the fixed rate cliff becomes a catalyst for better long-term financial outcomes rather than just a source of payment stress.
