The UK mortgage market remained highly sensitive this week as global uncertainty, inflation concerns, and rising government borrowing costs continued to influence mortgage pricing and buyer confidence.
While some lenders continued adjusting rates downward earlier in May, overall market sentiment became more cautious again as swap rates and gilt yields increased. At the same time, new housing market data suggested that activity has remained more resilient than many expected despite affordability pressures.
Here’s what happened in the UK mortgage market between the 11th and 18th of May 2026, and what it means if you’re buying, remortgaging, or reviewing your mortgage options.
Mortgage rates: volatility continues
Mortgage pricing remained volatile this week as lenders reacted to continued market uncertainty.
Key developments included:
- Rising swap rates and gilt yields
- Some lenders pausing recent rate reductions
- Continued repricing across fixed mortgage products
- Growing popularity of tracker mortgages
Recent reports suggest average UK mortgage rates remain around:
- 5.7%–5.9% for 2-year fixed mortgages
- 5.6%–5.8% for 5-year fixed mortgages
Some lenders, including Santander, Nationwide, NatWest and Virgin Money, had reduced selected rates earlier in May, but pricing momentum has become far less consistent over the last seven days.
Why mortgage rates are still elevated
Mortgage rates continue to be driven more by market expectations than by immediate Bank of England changes.
This week, upward pressure came from:
- Rising government borrowing costs
- Higher oil and energy prices
- Inflation concerns linked to global events
- Increased volatility in financial markets
UK gilt yields reached their highest levels since 2008 during the week before easing slightly. Because swap rates tend to move alongside gilt yields, this directly impacts fixed mortgage pricing.
The market is increasingly focused on whether inflation will remain higher for longer, reducing confidence around near-term base rate cuts.
Housing market: resilience despite uncertainty
Despite higher borrowing costs, the UK housing market has shown signs of resilience.
New Rightmove data released this week showed:
- UK asking prices rose 1.2% in May
- This was above the long-term May average increase
- Buyer and seller activity remained relatively stable
Rightmove also reported that agreed sales were only modestly below last year’s levels despite ongoing affordability pressures and global uncertainty.
However, survey data from RICS suggested buyer demand weakened in some parts of England and Wales, particularly in London and the South East where affordability pressures remain most severe.
First-time buyers: low-deposit lending returns
One of the biggest developments this week came from Lloyds Bank, which launched a new low-deposit mortgage product for first-time buyers.
The product allows eligible buyers to purchase with:
- Just a £5,000 deposit
- Up to 98% loan-to-value borrowing
- A maximum property value of £300,000
The move highlights how some lenders are trying to improve accessibility for buyers struggling to save larger deposits.
However, affordability remains a major challenge due to elevated mortgage rates and higher monthly payments.
Buy-to-let market: professional landlords gaining ground
New market reports this week showed continued changes within the buy-to-let sector.
Key trends included:
- Smaller landlords continuing to exit the market
- Professional landlords increasing activity
- Rental demand continuing to exceed supply
- Ongoing pressure on rents across many regions
Higher mortgage costs, tax changes, and increased regulation continue to reshape the buy-to-let market across the UK.
What we’re seeing from clients this week
Across London and the South East, we’re continuing to see:
- Increased urgency from buyers due to rate volatility
- More remortgage enquiries ahead of deal expiries
- Greater focus on affordability calculations
- Higher demand for lender flexibility
- More clients exploring tracker and variable-rate options
Many borrowers are prioritising certainty and lender fit over trying to perfectly time the market.
Oportfolio insight: what this means right now
The biggest message this week is that the mortgage market remains extremely reactive to wider economic events.
Even without a Bank of England rate change:
- Mortgage rates can move quickly
- Lenders can reprice products rapidly
- Affordability calculations can change significantly
Importantly, the difference between lenders remains substantial.
For borrowers with:
- Bonus income
- Self-employed income
- Complex affordability
- Larger loan sizes
Choosing the right lender can often make a bigger difference than small headline rate movements.
What this means if you’re buying vs remortgaging
If you’re buying
- Affordability remains stretched
- Mortgage rates are still elevated
- Understanding your borrowing early is increasingly important
- Low-deposit products are returning, but criteria remains strict
If you’re remortgaging
- Planning ahead remains essential
- Many lenders still allow rates to be secured months in advance
- Waiting does not guarantee cheaper rates
- Product structure is becoming increasingly important
