Tracker vs Fixed
March 2026: Why Halifax's 3.96% Tracker Beats NatWest's 4.52% Fixed Rate – But For How Long?
Halifax's tracker mortgage at 3.96% offers £1,820 savings over two years compared to NatWest's 4.52% fixed rate. But base rate rises above 4.31% would eliminate this advantage entirely.
The Numbers Tell a Compelling Story
With the Bank of England base rate holding at 3.75%, mortgage borrowers face a fascinating dilemma in March 2026. Halifax's tracker mortgage at 3.96% presents a significant 0.56 percentage point advantage over NatWest's leading 2-year fixed rate at 4.52%. However, this rate differential masks a more complex decision that could save or cost you thousands depending on the Bank's next moves.
The current market presents an unusual scenario where variable rate lending sits comfortably below fixed alternatives – a reversal from the traditional risk premium we typically see with trackers. Let's dissect whether this advantage justifies the inherent uncertainty.
Head-to-Head: The Market Leaders
Halifax Tracker Mortgage: 3.96%
- Rate: 3.96% (Bank of England base rate + 0.21%)
- Arrangement fee: £999
- Rate flexibility: Moves with base rate changes
- Early repayment charges: Typically none after initial period
NatWest 2-Year Fixed: 4.52%
- Rate: 4.52% fixed for 24 months
- Arrangement fee: £995
- Rate security: Guaranteed unchanged for two years
- Early repayment charges: Apply during fixed period
Real-World Cost Analysis: £250,000 Over 25 Years
To illustrate the financial impact, consider a typical £250,000 mortgage over 25 years at 60% loan-to-value:
Halifax Tracker (3.96%)
- Monthly payment: £1,317
- Total cost over initial 2 years: £32,607 (including £999 fee)
- Interest paid in first 2 years: £19,608
NatWest 2-Year Fixed (4.52%)
- Monthly payment: £1,393
- Total cost over 2 years: £34,427 (including £995 fee)
- Interest paid in first 2 years: £21,432
The tracker advantage: £1,820 less over two years, assuming base rate remains constant. That's £76 monthly savings – enough for a decent weekend meal out or additional overpayments to reduce your mortgage term.
The Base Rate Tipping Point
Halifax's tracker becomes more expensive than NatWest's fix if the base rate rises above 4.31% (which would push the tracker to approximately 4.52%). This represents a 0.56 percentage point increase from today's 3.75% level.
Historically, base rate movements of this magnitude can occur within 12-18 months during monetary tightening cycles. The Bank of England's next Monetary Policy Committee decisions are scheduled for 9th May and 20th June 2026, making these dates crucial for tracker holders.
For perspective, if base rate increased to 4.25%, the Halifax tracker would rise to 4.46% – still marginally cheaper than the NatWest fix. However, a further quarter-point rise would eliminate the tracker's advantage entirely.
Risk Versus Reward: Market Context
The current 0.21% margin on Halifax's tracker represents exceptional value in historical terms. Most tracker products typically sit 0.5-1.0% above base rate, making this offering particularly competitive.
However, fixed rates have compressed significantly since their peaks in late 2023. NatWest's 2-year fix reflects lenders' expectations that base rate may indeed rise from current levels, effectively pricing in future rate increases.
This creates an interesting arbitrage opportunity for borrowers willing to accept base rate risk in exchange for immediate savings and long-term flexibility.
Alternative Considerations
While our comparison focuses on the market leaders, borrowers should consider NatWest's 5-year fixed rate at 4.69%. Despite the higher rate, this product offers five years of certainty for just 0.17 percentage points more than their 2-year equivalent – potentially attractive given current rate volatility.
Those seeking even longer-term security might examine Nationwide's 10-year fix at 5.04%, though this carries a significant premium over current tracker rates.
The Verdict: Matching Products to Borrowers
Choose Halifax's Tracker If:
- You believe base rate will remain stable or fall over the next 2-3 years
- You value payment flexibility and want to benefit from potential rate cuts
- You can afford modest payment increases should rates rise
- You plan to move or remortgage within 2-3 years anyway
Choose NatWest's 2-Year Fix If:
- You prioritise payment certainty and budgeting predictability
- You're concerned about inflation pressures driving base rate higher
- You're stretching affordability and can't risk payment increases
- You prefer knowing exactly what you'll pay for the next 24 months
For most borrowers in stable employment with reasonable financial buffers, Halifax's tracker presents compelling value. The immediate savings are substantial, and the base rate would need to rise significantly to eliminate the advantage entirely.
However, those prioritising certainty or operating with tight budgets may find NatWest's fix worth the premium for guaranteed payments.

Frequently Asked Questions
How exactly does Halifax's tracker mortgage work with base rate changes?
Halifax's tracker sits at base rate plus 0.21%, currently totalling 3.96%. When the Bank of England changes base rate, your mortgage rate adjusts automatically on the same day. If base rate rises by 0.25%, your rate becomes 4.21%. If it falls by 0.25%, you pay 3.71%. There's typically no minimum rate floor, so you benefit from any base rate cuts.
Can I switch from the Halifax tracker to a fixed rate later without penalties?
Tracker mortgages typically don't have early repayment charges after any initial tie-in period, giving you flexibility to remortgage whenever rates become attractive. However, you'll need to meet lending criteria at that time and may face arrangement fees for a new product. Always check your specific terms, as some trackers do have ERCs for the first 1-2 years.
What's the likelihood of base rate rising above 4.31% in the next two years?
This depends on inflation, economic growth, and global factors. Currently at 3.75%, base rate would need to rise 0.56 percentage points to reach 4.31%. While possible, this would require sustained inflationary pressure or economic overheating. Money markets and fixed rate pricing suggest lenders expect modest rises, but predicting Bank of England policy remains challenging.
Should I fix for 2 years or 5 years given current rate uncertainty?
NatWest's 5-year fix at 4.69% costs just 0.17% more than their 2-year option, offering excellent value for extended certainty. If you're risk-averse and plan to stay put, the 5-year provides protection against multiple rate cycles. However, if you might move house or expect rates to fall medium-term, the shorter fix maintains more flexibility.
What happens to my Halifax tracker if base rate falls below current levels?
Your tracker rate would fall automatically, providing immediate payment reductions. At base rate of 3.50%, you'd pay 3.71%. At 3.25%, you'd pay 3.46%. This downside protection is tracker mortgages' key advantage – you benefit immediately from any Bank of England rate cuts, unlike fixed rate borrowers who must wait until their deal expires.
