What this article covers: The mortgage rate cuts announced by major lenders in the week of 7 to 13 May 2026, why the average two-year fixed rate remains close to 6% despite those cuts, the role of gilt yields and swap rates in setting mortgage pricing, and the political and market backdrop that pushed gilt yields to multi-decade highs in mid-May. What it does not cover: Advice on whether to fix, remortgage, or stay on a tracker. That depends on your individual circumstances and a qualified mortgage broker is best placed to help you with that decision.
Several of the UK’s biggest mortgage lenders reduced rates this week. Santander cut by up to 50 basis points from 11 May. Halifax trimmed up to 35 basis points on remortgage, first-time buyer, and home mover products. BM Solutions, Halifax’s buy-to-let arm, cut product transfer rates by up to 25 basis points. Nationwide reduced two, three, and five-year fixed rates by up to 25 basis points. If you have been watching the headlines, you could be forgiven for thinking the direction of travel is clearly down.
Except the average two-year fixed mortgage rate is currently around 5.78%, according to Uswitch’s live rate tracker. That is up from 4.84% in early March 2026, and higher than the 5.58% spike recorded on 26 March. Rates are near their highest level in over a year. So how do you square a week of lender cuts with an average rate that is sitting nearly six percentage points above zero?
The answer is in what is happening to UK government borrowing costs right now, and in the difference between a lender trimming its margin under competitive pressure and a wholesale repricing of mortgage debt. This article explains both.
In short
- Santander cut rates by up to 50bps from 11 May; Halifax by up to 35bps; BM Solutions (BTL) by up to 25bps; Nationwide by up to 25bps on two, three, and five-year fixes.
- Despite those cuts, the average two-year fixed rate is around 5.78% as of mid-May 2026, up from 4.84% in early March.
- UK ten-year gilt yields hit 5.1% on 11 to 13 May 2026, the highest since July 2008. The thirty-year gilt briefly touched 5.81%, the highest since 1998.
- Swap rates, which track gilt yields and determine what lenders pay for wholesale funding, remain elevated. That is why the average rate has not fallen despite individual lender cuts.
- Political uncertainty added to market pressure. Over 70 Labour MPs publicly called for Keir Starmer’s resignation following local-election losses. Pantheon Macroeconomics estimated that replacing the Prime Minister could add around 45 basis points to ten-year UK borrowing costs.
- The Bank of England held the base rate at 3.75% on 30 April (8-1 vote). The next Monetary Policy Committee meeting is 18 June.
- The May lender cuts reflect margin trimming under competition. They are not a signal that wholesale mortgage funding costs have fallen.
What lenders actually cut this week
Four major lenders made rate changes in the week of 7 to 13 May 2026. Here is what each one changed, according to data from Kael Tripton’s mortgage rate tracker and coverage from MPA Magazine.
Santander: up to 50bps from 11 May
Santander made the sharpest single-lender cut of the week, reducing selected fixed rates by up to 50 basis points from 11 May. A 50-basis-point cut on a five-year fix sounds material, and on paper it is. On a £250,000 repayment mortgage over 25 years, 50bps lower translates to roughly £65 to £75 less per month depending on the starting rate, before fees. That said, Santander’s cuts were selective: the deepest reductions applied to specific loan-to-value bands and product types, not across the board.
Halifax: up to 35bps on remortgage, FTB, and home mover
Halifax reduced rates by up to 35 basis points across remortgage, first-time buyer, and home mover product ranges. Halifax is the UK’s largest mortgage lender by volume, so its pricing tends to signal where the high-street market is heading. The fact that it cut, rather than held or increased, is notable. Again, “up to” matters here: the deepest cuts apply to the products where Halifax wants to win business, typically lower loan-to-value tiers where default risk is lower.
BM Solutions: up to 25bps on buy-to-let product transfers
BM Solutions, which is Halifax’s specialist buy-to-let brand, cut product transfer rates by up to 25 basis points. Product transfers (where an existing customer moves to a new deal with the same lender rather than remortgaging to a new one) are a competitive battleground. Lenders have been fighting to retain existing landlord customers rather than cede them to rivals, and this cut fits that pattern. BM Solutions did not cut across all BTL products or for new purchases.
Nationwide: up to 25bps on two, three, and five-year fixes
Nationwide reduced rates by up to 25 basis points on its two-year, three-year, and five-year fixed-rate products. As a mutual building society rather than a shareholder-owned bank, Nationwide often sets rates slightly differently from the big banks, and its willingness to cut across multiple fixed-rate terms is worth watching. As with the other lenders, the reductions are selective within each term band rather than uniform.
Why the average rate is still nearly 6%
A week of lender cuts might suggest rates are falling broadly. They are not, at least not yet, and understanding why requires a brief explanation of how mortgage pricing works.
The swap rate connection
When a bank or building society offers you a fixed-rate mortgage, it does not just lend you its depositors’ money at a rate it picks out of thin air. It hedges its interest-rate risk using instruments called interest-rate swaps. In a swap, the lender pays a fixed rate to a counterparty and receives a floating rate in return (or vice versa). The fixed rate it pays in that swap is the swap rate, and it closely tracks the yield on UK government bonds (gilts) of a similar term.
In practical terms: a two-year fixed mortgage rate is built roughly on top of the two-year sterling swap rate, plus the lender’s funding costs, plus its margin, plus any product fee offset. When swap rates rise, the raw ingredient for fixed mortgage pricing gets more expensive, and lenders either raise mortgage rates or take a margin hit. When swap rates fall, the opposite is true.
The key point is that a lender cutting its margin, while swap rates remain elevated, does not move the average market rate much. What the May cuts represent is lenders trimming their own profitability to stay competitive, not a reduction in what the market as a whole is paying for two-year money.
Where swap rates and gilt yields are right now
UK gilt yields have risen sharply since March 2026. The ten-year gilt yield, which is the most-watched benchmark for medium-term UK borrowing costs, hit 5.1% on 11 to 13 May. That is the highest level since July 2008, in the middle of the global financial crisis. The thirty-year gilt briefly touched 5.81%, a level not seen since 1998.
For context: when the average two-year fixed mortgage rate was 4.84% in early March, gilt yields were considerably lower. The subsequent rise in yields explains most of the 94-basis-point increase in average mortgage rates since then. The Uswitch live tracker put the average two-year fix at around 5.78% as of mid-May, and that number is unlikely to fall significantly until gilt yields come down.
Swap rates move closely with gilt yields rather than with the Bank of England base rate. This is a frequent source of confusion: people see the base rate at 3.75% and wonder why mortgage rates are double that. The base rate governs overnight lending between banks; it does not directly set the multi-year borrowing costs that determine fixed mortgage rates. What matters for fixed rates is the multi-year gilt yield, and that has been rising.
The political backdrop driving gilt yields
Gilt yields do not rise in a vacuum. The spike to multi-decade highs in mid-May 2026 had a specific trigger: acute uncertainty about the future of the UK government.
Following local-election losses in early May, more than 70 Labour MPs publicly called for Keir Starmer to resign as Prime Minister. The calls came from a broad cross-section of the parliamentary party, not just the usual critics, and financial markets took notice. Bloomberg reported on 12 May that gilts were selling off with the Prime Minister under visible pressure, and CNBC reported the same day that UK government borrowing costs were rising as political uncertainty intensified.
The market’s concern is not really about who is Prime Minister in human terms; it is about what a leadership change signals for fiscal stability and policy continuity. Markets price government bonds based partly on their confidence that a government will manage debt sustainably and predictably. Sudden political upheaval, of the kind that forces a mid-term leadership contest, raises the risk premium that investors demand to hold that government’s debt. Higher risk premium means higher yields.
Pantheon Macroeconomics, a widely-cited UK economic research firm, put a specific number on this. Their estimate: replacing the Prime Minister could add approximately 45 basis points to ten-year UK borrowing costs. That is not a certainty and not a precise forecast of what would happen, but it gives a sense of the order of magnitude markets are considering. ShareScope’s bi-weekly commentary for 13 May noted that gilt market signals were pointing to a sustained period of elevated borrowing costs, with the political situation listed as a live contributing factor.
It is worth being precise about what this means and what it does not mean. Rising gilt yields following political pressure are not a verdict on the merits of any political position. They are a reflection of investor uncertainty about continuity and stability. Markets do not reward or punish particular policies as such; they price risk. Political events that increase uncertainty tend to raise the risk premium on government debt, and that feeds through to mortgage rates via the swap-rate mechanism described above.
What this means for borrowers
The picture varies considerably depending on where you are in the mortgage cycle.
Your fixed deal is ending in the next three to six months
This is the group most exposed to current conditions. If you fixed two or three years ago at rates below 3%, you are facing a significant payment increase when you remortgage. The average two-year fix at 5.78% is nearly three percentage points higher than what many borrowers fixed at in 2022 to 2024.
The practical options are the same as they have always been: fix again, move to a tracker that follows the base rate, or stay on the standard variable rate (which is almost always the most expensive option). Many lenders allow you to lock in a rate up to six months before your deal ends, which means you can act now on current pricing rather than waiting to see if rates move before your deal expires. Whether to lock in now, wait, or speak to a broker about your specific situation is a decision only you can make with full knowledge of your own finances.
You are a first-time buyer looking now
The Halifax cuts specifically included first-time buyer products, which is a signal that lenders want this segment of the market. Affordability has tightened significantly from the rate lows of 2020 to 2021, but the cuts this week mean that the best-buy first-time buyer rates are slightly more competitive than they were last week. Comparing across lenders, and factoring in fees (arrangement fees of £999 to £1,499 are common), is worthwhile. A mortgage broker can compare the whole market rather than the front-of-book deals that appear in the press.
You are a buy-to-let landlord
The BM Solutions product transfer cuts are specifically relevant here. If you are new to the landlord market, our property investment for beginners guide covers the fundamentals alongside the rate environment. Landlords on existing BM Solutions products who are coming up for renewal are in a better position today than they were a fortnight ago, albeit only marginally. The BTL market has additional complications from tax changes and stress-test affordability rules that do not apply to residential mortgages; the rate environment is just one variable among several.
You are considering a second-charge mortgage
Second-charge mortgages (secured loans taken against a property you already own) are priced differently from first-charge products and are not directly affected by the same week-to-week lender rate movements. They tend to carry a higher rate than first-charge mortgages and their pricing is influenced by the broader secured-lending market. If you are weighing a second charge against remortgaging, comparing the total cost across both options in full is the right starting point.
What this means for savers
The conventional wisdom is that when mortgage rates fall, savings rates follow. That is a reasonable rule of thumb in a normal rate cycle. But the current situation is not straightforwardly normal, and it is worth thinking about what elevated gilt yields mean for savers.
Savings rates have been higher over the past two years than at any point in roughly fifteen years. Easy-access rates above 4.5%, fixed-term cash ISA rates above 4.8%, and premium bonds prizes linked to a prize fund rate of 4.4% (as of mid-2026) have given cautious savers returns they have not seen since before the 2008 financial crisis. The question is how long that lasts.
The answer depends on what happens to gilt yields and the Bank of England base rate. If gilt yields remain elevated because of sustained political or fiscal uncertainty in the UK, then the interest rate environment stays higher for longer across the board, including for savers. The Bank of England held the base rate at 3.75% on 30 April by an 8 to 1 vote. The single dissenting member voted for a further cut. The next MPC meeting is 18 June.
If the political situation stabilises and gilt yields retreat from their current highs, you would expect some pass-through to lower savings rates over time. Best-buy savings accounts tend to reprice within weeks of a base rate change, and some fixed-term bonds reprice even faster if market expectations shift. Savers who want to lock in current rates for a year or two before a potential cut cycle accelerates may find fixed-term accounts or cash ISAs worth looking at now, before a rate reduction changes the available options.
None of this is to say that savings rates are definitely about to fall. It is simply to note that the rate-cut narrative for mortgages does not automatically translate into lower savings rates in the near term, and the current gilt-yield environment may actually support savings rates staying elevated for longer than markets were pricing a few months ago.
FAQ
When will mortgage rates actually fall significantly?
No one can say with certainty. Mortgage rates are built primarily on swap rates, which track gilt yields. For rates to fall materially, gilt yields need to come down, and that requires either a significant easing of inflationary pressure, a reduction in fiscal risk, or a change in the political and market backdrop that is currently pushing yields up. The Bank of England base rate at 3.75% is already below recent highs, but that alone is not enough if gilt yields remain elevated. Watching the ten-year gilt yield, rather than waiting for base rate announcements, gives a better real-time signal of where fixed mortgage rates are heading.
Should I fix now or wait?
This is a personal decision that depends on your specific circumstances, including how much you owe, when your current deal ends, your income stability, and your appetite for rate risk. Savvy Investor Guide does not give personal financial advice, and neither does this article. What we can say is that the factors pointing toward fixing sooner include elevated gilt yields that may not fall quickly, the option to lock in a rate up to six months before your deal ends, and the risk that if gilt yields rise further, current rates could look attractive in hindsight. The factors pointing toward waiting include the possibility that political uncertainty resolves, yields fall, and rates come down before your deal expires. A qualified, FCA-authorised mortgage broker can model both scenarios against your actual numbers.
What is a swap rate, and why does it matter for mortgages?
An interest-rate swap is a financial contract where two parties exchange interest payments: typically one pays a fixed rate and the other pays a floating rate. Banks and building societies use swaps to hedge the interest-rate risk they take on when offering fixed-rate mortgages. The fixed rate they pay in those swap contracts (the swap rate) closely tracks gilt yields of a similar term. When swap rates rise, the cost of funding a fixed-rate mortgage goes up, and lenders generally pass that cost on in the form of higher mortgage rates. The swap rate is not published in the newspaper, but you can follow UK gilt yields as a close proxy: if the ten-year gilt yield is rising, two-year and five-year mortgage rates are likely to follow.
How does the Bank of England base rate relate to mortgage rates?
The base rate directly affects variable-rate and tracker mortgages, which are priced as “base rate plus X%”. It has limited direct effect on fixed-rate mortgages. Fixed rates are determined primarily by swap rates, which track gilt yields rather than the base rate. This is why the base rate can stay at 3.75% while the average two-year fixed rate is 5.78%: the gap reflects the market’s pricing of medium-term interest-rate risk and UK fiscal risk, not a simple markup over the base rate. When the base rate falls, it usually brings tracker and variable rates down with it, and may eventually influence swap rates and fixed rates if markets expect the cuts to be sustained, but the relationship is indirect.
What would happen to mortgage rates if the Prime Minister changed?
Markets are already pricing some degree of political uncertainty into gilt yields. Pantheon Macroeconomics estimated that a change in Prime Minister could add around 45 basis points to ten-year UK borrowing costs, above whatever the market is already pricing in. If that were to happen and gilt yields rose by that amount, swap rates and fixed mortgage rates would be expected to follow, at least in the short term, before markets reassessed the fiscal position of the incoming administration. This is not a prediction of what would happen; it is an estimate of the market’s sensitivity to that scenario based on current conditions.
How do I check when my current mortgage deal ends?
The simplest starting point is your original mortgage offer letter or your most recent annual mortgage statement, both of which will show the initial term of your fixed or discounted rate and the date it converts to your lender’s standard variable rate. If you cannot find the paperwork, call your lender’s mortgage servicing team and ask directly; they are required to provide this information. Most lenders also display your product end date in their online mortgage account portal. Once you know the date, most lenders and brokers allow you to start shopping for a new deal up to six months before that date, so you have time to compare without being rushed.
Are savings rates likely to stay high for much longer?
The elevated savings rates of 2024 to 2026 have been driven by a combination of the Bank of England base rate at historically high levels and competition between providers. If the base rate falls further and gilt yields ease, savings rates will follow, though there is usually a lag. In the current environment, where gilt yields remain elevated partly because of political uncertainty, the timeline for that repricing is harder to predict than it would be in a more stable market. Providers offering the best rates on easy-access accounts and fixed-term products can change their offers quickly when conditions change, so anyone wanting to lock in current rates for a fixed term has a finite window to do so.
Savvy Investor’s take
The week’s rate cuts are real. Lenders competing for remortgage and first-time buyer business are trimming margins, and for individual borrowers on the right product at the right LTV, those cuts translate to genuine savings. But the broader picture is that the UK mortgage market is operating in an environment where the wholesale funding costs have risen sharply since March, driven by gilt-yield dynamics that are only loosely connected to what the Bank of England decides at its quarterly meetings.
The gap between the base rate of 3.75% and the average two-year fixed rate of around 5.78% is telling you something. It is telling you that the market is pricing meaningful UK fiscal and political risk into medium-term borrowing costs. Until that risk premium eases, either because political uncertainty resolves or because the UK’s fiscal trajectory reassures bond investors, the average mortgage rate is unlikely to fall quickly, no matter how many individual lenders trim their offerings in any given week.
For borrowers, the practical implication is to watch gilt yields, not just lender announcements, as the leading indicator of where rates are heading. For savers, the implication may be the opposite of what the mortgage headlines suggest: elevated yields support higher savings rates staying in place longer than many anticipated at the start of 2026.
