Major Rate Turbulence: HSBC Hikes 60bp While Barclays Makes 1%+ Leap - 29 March 2026

Sunday Shakeup: Four Major Lenders Push Rates Higher

Sunday 29th March has delivered a coordinated upward assault on mortgage rates, with four major lenders implementing significant increases across their ranges. The moves represent one of the most substantial single-day rate adjustments we've seen this year, affecting borrowers from first-time buyers to buy-to-let investors.

Leading the charge is HSBC with systematic increases of 30-60 basis points across virtually every product in their range. Meanwhile, Barclays has delivered the most dramatic shock with increases exceeding 100 basis points on many products. NatWest and Nationwide have also contributed to the upward momentum with more measured but still meaningful adjustments.

HSBC's Comprehensive Rate Restructure

HSBC has implemented the most comprehensive rate review, touching every corner of their mortgage range. The pattern is clear: existing customer products saw the smallest increases at 15-40 basis points, while new business rates jumped by 50-60 basis points.

For residential mortgages, first-time buyers now face rates of 5.17% for 2-year fixes at 60% LTV (up from 4.57%), while the 5-year equivalent has risen to 5.18% from 4.68%. Home movers have seen similar treatment, with 2-year rates climbing to 5.09% from 4.49% at the same LTV band.

The buy-to-let sector hasn't escaped the adjustment. New BTL purchase rates have increased to 5.03% for 2-year fixes at 60% LTV, up 60 basis points from 4.43%. Energy-efficient properties retain identical pricing, suggesting HSBC sees no risk differential worth pricing between standard and green BTL properties.

International customers face the steepest rates in HSBC's range, with 2-year fixes now priced at 5.58% at 60% LTV, representing a 60 basis point increase from 4.98%. These premium rates reflect the additional risk assessment HSBC applies to overseas borrowers.

Existing Customer Protection Strategy

HSBC's existing customers have received preferential treatment in this repricing exercise. Rate switches for current residential borrowers saw increases of just 20-40 basis points, with 2-year fixes now at 4.69% at 60% LTV compared to 4.29% previously. This selective approach suggests HSBC is prioritising customer retention while maximising margins on new business.

Barclays Delivers Market Shock

Barclays has implemented the most aggressive repricing of the day, with some products seeing increases exceeding 100 basis points. The scale of adjustment suggests significant internal reassessment of risk pricing or funding cost pressures.

New purchase rates have jumped dramatically across all LTV bands. At 60% LTV, 2-year fixes have risen to 4.60% from 3.55% – a massive 105 basis point increase. Five-year fixes have seen identical treatment, jumping to 4.80% from 3.75%.

The pattern intensifies at higher LTVs. At 90% LTV, new purchase 2-year rates have increased to 4.95% from 4.22%, while 5-year equivalents now sit at 4.96% versus 4.25% previously. These moves place Barclays at the higher end of current market pricing for new business.

Remortgage customers face similarly steep increases, with 2-year rates at 60% LTV rising to 4.66% from 3.62% – a 104 basis point jump that will significantly impact affordability calculations for customers looking to switch.

Nationwide's Measured March Upward

Nationwide has taken a more restrained approach, implementing increases of 10-30 basis points across their range. First-time buyer rates have seen 30 basis point increases, with 2-year fixes at 60% LTV now priced at 4.85%, up from 4.55%.

The building society's existing borrower rates have received even gentler treatment, with home mover products for current customers seeing increases of just 25-30 basis points. This suggests Nationwide is following HSBC's customer retention strategy while remaining competitive for new business.

At higher LTVs, Nationwide's increases become more pronounced. The 95% LTV segment has seen 2-year rates rise to 5.55% from 5.40% for first-time buyers, maintaining their position as one of the few lenders actively competing in this space.

NatWest Targets New Business

NatWest's adjustments have been more selective, focusing primarily on new business rather than existing customer products. New purchase rates have increased by 22-39 basis points, with 2-year fixes at 60% LTV now at 4.52%, up from 4.15%.

The bank's remortgage pricing has seen slightly larger adjustments, with increases of 20-52 basis points depending on the product and LTV band. This suggests NatWest is particularly focused on improving margins from customers switching from other lenders.

Market Position Analysis

Following today's changes, NatWest has emerged with some of the most competitive headline rates. Their 2-year fix at 4.52% for new purchases at 60% LTV now represents the best rate in our current tracking, though this competitive position may prove temporary given the rapid pace of market adjustments.

Implications for Borrowers

Today's coordinated rate increases signal a fundamental shift in lender appetite and pricing strategy. The scale and coordination of the moves suggest underlying funding cost pressures or regulatory capital considerations are driving decision-making across the major lenders.

Current mortgage applicants should expect further volatility in the coming weeks. The pattern of protecting existing customers while raising new business rates suggests lenders are prioritising profitability over market share growth.

For those currently in the market, the narrow window between rate changes emphasises the importance of swift decision-making. Applications submitted and accepted before rate changes take effect remain protected, but delays in processing could result in significantly higher costs.

The differential treatment between new business and existing customers creates a two-tier market that rewards loyalty but penalises those seeking to switch lenders. This trend may accelerate if funding conditions continue to deteriorate.

With the Bank of England base rate currently at 3.75%, today's increases push many mortgage rates significantly above historical norms relative to base rate. This suggests lenders are building additional risk premiums into their pricing or facing increased funding costs that exceed base rate movements.
