2nd September 2026
For a while it looked as though the great mortgage squeeze might finally be coming to an end.
Interest rates had fallen from their peak. Inflation appeared to be moving in the right direction. Competition between lenders had produced some increasingly attractive fixed-rate mortgage deals and there was a growing expectation that the Bank of England would eventually be able to reduce interest rates further.
Then the bond market turned.
Suddenly the outlook looks rather less comfortable.
The Bank of England's Bank Rate is currently 3.75% and the next decision is not until 17 September. The most recent decision was actually a hold, although three members of the Monetary Policy Committee wanted rates increased to 4%.
Yet mortgage rates do not simply follow Bank Rate up and down.
That is one of the most important things for homeowners to understand.
Fixed mortgage rates are influenced heavily by what happens in the financial markets, particularly the cost to lenders of raising money over the period for which they are offering the fixed rate. And that means the recent surge in government bond yields matters.
On Tuesday, the yield on Britain's 10-year gilt reached about 5.25%, its highest level since the financial crisis, while the 30-year gilt yield approached 5.9%, its highest level since 1998.
For most people those figures will mean very little.
A mortgage does.
Because when the financial markets decide that borrowing money is going to be more expensive for longer, lenders have to take that into account when pricing new mortgages.
That is why the apparent contradiction has emerged.
The Bank of England has not raised Bank Rate.
Yet some mortgage rates are rising.
For homeowners coming to the end of a fixed-rate deal, that distinction could become extremely important.
Someone who fixed their mortgage several years ago at a very low rate may have been protected from the worst of the increases. But when that fixed period expires, they have to find a new deal.
And the new deal is based on the market as it exists then, not the market that existed when they originally borrowed the money.
That creates a financial shock for some households.
Take a household with a £200,000 mortgage.
At 2%, the annual interest component, before considering the capital repayment, is roughly £4,000.
At 5%, it is roughly £10,000.
That does not mean the mortgage payment itself simply rises by £500 a month because repayments also depend on the remaining term and the way the mortgage is structured. But it demonstrates the scale of the change in the underlying cost of borrowing.
For a family already facing higher food prices, council tax, energy costs, insurance and other household bills, another substantial increase in the mortgage payment can be enough to change spending decisions.
Perhaps the family stops eating out.
Perhaps the new car is postponed.
Perhaps the house extension is cancelled.
Perhaps the child who was going to university receives less financial help.
Perhaps the family simply starts drawing down its savings.
This is why mortgages matter to the wider economy.
They are not just a housing story.
They are a consumer-spending story.
And that is where the current situation becomes particularly awkward for the Government and the Bank of England.
The UK economy needs households to spend and businesses to invest.
But if mortgage costs rise, disposable income falls.
A household with an extra £200 or £300 a month going into the mortgage account has less money available for everything else.
That can be good for controlling inflation because it reduces demand.
But it can also weaken an economy that is already struggling to generate strong growth.
The latest Bank of England figures provide a warning sign.
Mortgage approvals fell to 56,053 in July, the lowest monthly figure since January 2024.
That suggests people are becoming more cautious about taking on mortgages and buying homes.
House prices are still rising, but only modestly. Nationwide reported annual house-price growth of just 1.6% in August, below the rate of consumer-price inflation.
That is quite a different housing market from the boom years when prices seemed to rise almost regardless of what happened to the economy.
And perhaps that is no bad thing.
The problem is that a housing market does not operate in isolation.
Estate agents need buyers.
Builders need people willing to buy new homes.
Tradesmen need people willing to renovate them.
Furniture shops need people moving into properties.
Mortgage brokers, surveyors, solicitors and removal companies all depend on transactions taking place.
When mortgage costs rise, the whole chain can slow down.
There is also an uncomfortable issue for younger homeowners.
Many people who bought during the period of exceptionally low interest rates have never experienced a genuinely expensive mortgage.
For them, moving from a rate of perhaps 2% to something around 5% can be a very different financial experience.
It is not necessarily a catastrophe.
But it changes what they can afford.
And there is another group that can be particularly vulnerable: people who have stretched themselves to buy because house prices have remained high.
When interest rates were low, the monthly payment made the mortgage appear manageable.
Once rates rise, the underlying size of the debt becomes much more obvious.
This is one reason why the current bond-market turmoil deserves attention from people who have never bought a government bond in their lives.
The gilt market may seem like something that belongs to pension funds and investment managers.
But ultimately it affects the cost of money throughout the economy.
And the current problem is not simply that Britain has high interest rates.
It is that markets are beginning to question how long those rates may need to remain high.
The oil price is part of the problem.
The renewed conflict involving the United States and Iran has pushed energy prices higher and increased concerns about inflation. The Bank of England itself acknowledges that energy prices remain high and volatile because of the conflict in the Middle East.
If oil remains expensive, inflation may take longer to return to target.
If inflation stays high, the Bank of England has less freedom to cut rates.
If investors expect rates to remain higher, longer-term borrowing costs can remain elevated.
And if government borrowing costs continue rising, that can put further pressure on the public finances.
The mortgage market is therefore sitting at the end of a much bigger chain.
Oil prices.
Inflation.
Interest rates.
Government bonds.
Bank funding costs.
Mortgage rates.
Household spending.
It is all connected.
There is also a political problem here.
Governments have become accustomed to talking about the cost of living largely in terms of energy bills and food prices.
Mortgage costs are different.
They can remain hidden for years because millions of homeowners are protected by fixed-rate deals.
Then, when the fixed period ends, the increase arrives all at once.
That means the full impact of today's market conditions may not be felt immediately.
It can take months or even years to work through the mortgage book as individual fixed-rate deals expire.
This is why the Government cannot simply look at today's mortgage payments and assume that the problem is already priced into the economy.
The financial pressure is moving through the system gradually.
For some households it will barely be noticed.
For others it could be one of the largest increases in monthly expenditure they have ever faced.
There is an important lesson here for anyone considering a mortgage.
The cheapest mortgage deal available today is not necessarily the only figure that matters.
The size of the deposit, the length of the fixed period, the mortgage term and the household's ability to cope with higher rates all matter.
Nobody knows with certainty where interest rates will be next year or the year after.
That uncertainty is precisely what makes the current market so difficult.
For a long time borrowers were told that rates would eventually return to the exceptionally low levels seen before the inflation crisis.
That may still happen to some degree.
But there is no guarantee.
Britain's economic circumstances have changed.
Government debt is much higher.
Energy markets are more uncertain.
Geopolitical risks are greater.
And investors appear less willing to accept very low returns for lending money over long periods.
The result is that the era of ultra-cheap money may be over, even if Bank Rate eventually falls further.
That is probably the most important message for homeowners.
Do not assume that a Bank of England rate cut automatically means cheap mortgages are coming back.
It may help variable-rate borrowers.
It may eventually help fixed-rate borrowers.
But fixed mortgage rates depend on much more than the Bank Rate announcement made every few weeks.
The bond market has a say.
And at the moment the bond market is not particularly relaxed.
For people in Caithness and the wider Highlands, there is another dimension to this.
Housing is already a difficult subject. Building costs are high, wages are often lower than in parts of the south and there are continuing concerns about the availability of suitable homes.
If mortgage costs rise while house prices remain relatively high, getting onto the property ladder becomes harder.
And if young people cannot afford to buy, more may remain in private rented accommodation for longer.
That creates another pressure on the already stretched housing market.
So the mortgage story is not really about whether the next fixed-rate deal is 4.8%, 5% or 5.3%.
It is about whether Britain can get borrowing costs down without reigniting inflation.
That is a much harder problem.
The Bank of England cannot simply cut rates aggressively if energy prices are pushing inflation higher.
The Government cannot simply spend its way out of weak growth if the bond market is demanding higher returns on its debt.
And households cannot simply ignore higher mortgage payments when the money has to come from somewhere.
The uncomfortable truth is that cheap money cannot be assumed anymore.
The mortgage market is beginning to remind us of that.
And for millions of homeowners, the next letter from their mortgage lender could be considerably more important than the next speech from a politician.
