Tracker vs Fixed
Tracker vs Fixed Mortgage Showdown: March 2026 – Is 3.96% Tracker Worth the Risk?
Halifax's 3.96% tracker beats NatWest's 4.52% two-year fix by £73 monthly – but base rates only need to rise 0.56% to eliminate this advantage. We analyse the costs, risks, and reveal which mortgage type suits different borrower profiles in March 2026.
Today's Battle of the Best Rates
With mortgage rates showing signs of stabilisation in early 2026, borrowers face a compelling choice between immediate savings and rate security. Halifax's market-leading tracker at 3.96% (Base Rate + 0.21%) sits 0.56% below NatWest's best 2-year fixed deal at 4.52%, whilst the 5-year fix comes in at 4.69%.
Both the Halifax tracker and NatWest fixed deals carry similar arrangement fees (£999 vs £995), making the rate differential the primary battleground. But with the Bank of England base rate currently at 3.75%, the question isn't just about today's savings – it's about tomorrow's risks.
The Numbers: £250,000 Mortgage Comparison
Let's examine the real costs using a typical £250,000 mortgage over 25 years at 60% LTV:
Halifax Tracker (3.96%)
- Monthly payment: £1,321
- Arrangement fee: £999
- Total cost over 2 years: £32,703
NatWest 2-Year Fix (4.52%)
- Monthly payment: £1,394
- Arrangement fee: £995
- Total cost over 2 years: £34,451
NatWest 5-Year Fix (4.69%)
- Monthly payment: £1,414
- Arrangement fee: £995
- Total cost over 5 years: £85,835
The tracker delivers immediate savings of £73 monthly (£1,748 over two years) compared to the 2-year fix. However, this advantage evaporates if base rates rise significantly.
The Base Rate Tipping Point
Currently at 3.75%, the Bank of England base rate would need to increase by just 0.56% to 4.31% for Halifax's tracker to match NatWest's 2-year fix. This would push the tracker rate to 4.52% (4.31% + 0.21% margin).
More critically, base rates rising to 4.94% would make the tracker more expensive than even the 5-year fix. Given the current economic climate and inflation pressures, such movements aren't beyond possibility within a 2-year timeframe.
Rate Movement Scenarios
- Base rate rises to 4.0%: Tracker becomes 4.21% (still £33 monthly cheaper than 2yr fix)
- Base rate rises to 4.5%: Tracker becomes 4.71% (£21 monthly more expensive than 2yr fix)
- Base rate falls to 3.5%: Tracker becomes 3.71% (£98 monthly cheaper than 2yr fix)
Market Context and Economic Outlook
The 0.56% gap between tracker and fixed rates reflects market uncertainty about future monetary policy. Fixed rate pricing suggests lenders anticipate potential base rate increases, building in a premium for rate security.
The Monetary Policy Committee's next decision is scheduled for 6th May 2026, with quarterly inflation reports continuing to influence rate expectations. Current market pricing indicates roughly a 60% probability of at least one 0.25% rate increase by year-end 2026.
Risk vs Reward Analysis
Tracker Advantages
- Immediate monthly savings of £73 vs 2-year fix
- Benefits from any base rate cuts
- No early repayment charges typically after initial period
- Flexibility to switch products more easily
Fixed Rate Security
- Payment certainty regardless of rate movements
- Protection against significant rate increases
- Budgeting clarity for household planning
- 5-year option provides longer-term stability
Who Should Choose Which?
Tracker Suits:
- Borrowers comfortable with payment fluctuations
- Those expecting base rates to remain stable or fall
- Customers planning to overpay or move within 2-3 years
- Rate-watchers who actively manage their mortgage
Fixed Rate Suits:
- First-time buyers prioritising payment certainty
- Households on tight budgets requiring predictable costs
- Risk-averse borrowers concerned about rate rises
- Those seeking longer-term financial planning stability
The Professional Verdict
Halifax's 3.96% tracker offers compelling value for borrowers willing to accept rate risk. The immediate savings are substantial – nearly £1,750 over two years compared to fixing. However, this advantage could reverse quickly if base rates rise as little as 0.75%.
For maximum flexibility with reasonable protection, consider the 2-year fix as a middle ground. It provides rate security through potential near-term volatility whilst allowing reassessment in 2028. The 5-year fix makes sense only for those prioritising absolute certainty or expecting significant rate increases.
Given current market conditions, the tracker represents the best value for financially resilient borrowers, but fixing offers essential peace of mind for stretched households. Use our mortgage comparison tool to model different scenarios based on your specific circumstances.

Frequently Asked Questions
How do tracker mortgages work and what's the margin?
Tracker mortgages follow the Bank of England base rate plus a fixed margin. Halifax's tracker charges base rate + 0.21%, so with base rate at 3.75%, you pay 3.96%. When base rate changes, your rate changes immediately, affecting your monthly payments.
What are the early repayment charges on these deals?
Halifax's tracker typically has no ERCs after any initial tie-in period. NatWest's fixed deals usually charge 1-3% of the outstanding balance for early repayment during the fixed term. Always check specific product terms as ERCs can significantly impact switching costs.
Where are base rates heading in 2026?
Market pricing suggests roughly 60% probability of at least one 0.25% base rate rise by end-2026. However, economic uncertainty means rates could move either direction. The MPC's next decision is 6th May 2026, with inflation data and economic growth key factors in their considerations.
Should I fix or track if I'm planning to move house?
If moving within 2-3 years, trackers often provide more flexibility as they typically have no ERCs after initial periods. Fixed rate ERCs can be costly if you need to exit early. However, consider portability options – many lenders allow you to transfer your existing deal to a new property.
What happens to my tracker rate if base rates fall significantly?
Your tracker rate falls with base rate decreases, but check for any 'collar' or minimum rate. Some trackers have floors below which rates won't fall. Halifax's current tracker would become 3.71% if base rates dropped to 3.5%, delivering even greater monthly savings versus fixed deals.
