Major Lender Rate Shake-Up: Sunday 29 March 2026 Mortgage Market Update

Sunday's mortgage market has delivered a weekend full of rate adjustments, with four major lenders implementing changes that will affect borrowers across different loan-to-value brackets. The moves span increases ranging from modest 9 basis point nudges to substantial jumps of over 100 basis points.

HSBC Leads the Charge with Comprehensive Rate Adjustments

HSBC has implemented the most extensive changes, affecting virtually every product in their range. The bank's existing customer products have seen relatively modest increases, with switching rates for residential customers at 60% LTV rising from 4.29% to 4.69% on two-year fixes—a 40 basis point jump that takes these deals to £999 fee territory.

More significant moves hit HSBC's new customer rates. First-time buyers at 60% LTV now face 5.17% on two-year deals (up from 4.57%), whilst five-year rates climbed from 4.68% to 5.18%. These 60 basis point increases represent some of the steepest climbs in today's adjustments.

The buy-to-let sector hasn't escaped HSBC's repricing either. Purchase BTL rates at 65% LTV jumped 60 basis points across both two and five-year terms, with two-year deals now priced at 5.14% compared to the previous 4.54%.

International customers face even steeper pricing, with HSBC's international purchase products at 60% LTV seeing two-year rates climb from 4.98% to 5.58%—a substantial 60 basis point increase that pushes these specialist products well above mainstream pricing.

Nationwide's Measured Increases Across All LTV Bands

Nationwide has taken a more measured approach, implementing smaller but broad-based increases. Their first-time buyer products have seen 30 basis point increases on two-year deals, with rates at 60% LTV moving from 4.55% to 4.85%.

The building society's home mover rates show consistent patterns across LTV bands. At 75% LTV, two-year home mover rates increased from 4.37% to 4.67%, whilst five-year deals rose from 4.50% to 4.75%. These 30 and 25 basis point moves respectively maintain Nationwide's competitive positioning whilst acknowledging current market pressures.

Particularly notable are Nationwide's high-LTV adjustments. At 95% LTV, first-time buyer two-year rates increased just 15 basis points from 5.40% to 5.55%, suggesting the lender remains keen to support this crucial market segment despite broader rate pressures.

Barclays Implements Dramatic Repricing Strategy

Barclays has delivered some of today's most dramatic changes, with several products seeing increases exceeding 100 basis points. Their existing customer switching rates at 60% LTV experienced the largest single adjustment, with two-year deals jumping from 3.52% to 4.80%—a massive 128 basis point increase.

New purchase rates have also seen substantial moves. At 60% LTV, two-year purchase deals increased from 3.55% to 4.60% (105 basis points), whilst five-year rates climbed identically from 3.75% to 4.80%. These changes suggest Barclays is fundamentally repositioning its pricing strategy.

The bank's remortgage products show similar patterns, with 75% LTV two-year deals rising from 3.75% to 4.68%—a 93 basis point increase that brings Barclays more in line with broader market pricing after what appears to have been an extended period of particularly competitive rates.

At higher LTV levels, Barclays' new purchase rates at 95% LTV saw two-year deals increase from 4.65% to 5.35% (70 basis points), whilst five-year rates climbed from 4.58% to 5.36% (78 basis points).

NatWest's Focused Adjustments

NatWest has implemented more modest changes, with most increases falling between 20 and 50 basis points. Their new purchase rates at 60% LTV rose from 4.15% to 4.52% on two-year deals—a 37 basis point increase that maintains competitive positioning.

The bank's remortgage rates show slightly larger adjustments, with 60% LTV two-year deals increasing 39 basis points from 4.17% to 4.56%. Tracker rates have seen more significant moves, with 60% LTV remortgage trackers climbing from 3.92% to 4.35%—a 43 basis point increase reflecting the challenging variable rate environment.

At 90% LTV, NatWest's approach becomes more conservative. New purchase two-year rates remained unchanged at 4.90%, whilst remortgage deals saw a modest 22 basis point increase from 4.92% to 5.14%.

Market Context and Current Competitive Landscape

Today's changes create a mixed picture across the mortgage market. The current best two-year fixed rates start at 4.52% from NatWest, whilst five-year deals begin at 4.69% from the same lender. Ten-year fixes remain available from 5.04% via Nationwide, and tracker rates start from 3.96%.

These weekend moves suggest lenders are responding to funding cost pressures and demand management needs rather than any immediate change to the Bank of England base rate, which remains at 3.75%. The scale of increases, particularly from Barclays, indicates some institutions may have been operating at unsustainably low margins.

For borrowers currently in the application process, these changes highlight the importance of securing rate locks where possible. The variation between lenders—with some implementing modest adjustments whilst others undertake comprehensive repricing—suggests shopping around remains crucial.

What This Means for Different Borrower Types

First-time buyers face particular challenges from today's changes, with HSBC's increases pushing their 60% LTV deals above 5% for the first time in recent months. However, Nationwide's more modest adjustments mean competitive options remain available.

Existing customers looking to switch within their current lender's range will find HSBC's increases make external remortgaging potentially more attractive. The 40 basis point increases across HSBC's switching products could drive more customers to explore alternatives.

Buy-to-let investors encounter a tougher environment, with HSBC's 60 basis point increases on purchase products significantly impacting yield calculations. The fact these increases span both standard and energy-efficient products suggests broad-based repricing rather than selective adjustments.

High-LTV borrowers see mixed outcomes, with Nationwide maintaining relatively modest increases at 95% LTV whilst Barclays implements more substantial changes at similar loan-to-value ratios.
