When we think about what affects house prices and mortgage rates in the UK, we naturally look at the Bank of England, Government decisions and the state of the British economy.
But what about events happening thousands of miles away?
The recent US midterm elections on 3 November 2026 have changed the political landscape in America, with the Democrats gaining control of both the House of Representatives and the Senate. Donald Trump, however, remains President, and the election does not automatically mean that his existing economic or trade policies will change.
So why should homeowners, buyers and sellers in Hertfordshire pay attention?
The answer is that the American economy has a significant influence on global financial markets. Decisions made in Washington can affect international borrowing costs, trade, investor confidence and, indirectly, the UK mortgage market.
We take a closer look at how American political developments can influence the British property market and what this could mean for people looking to move in Stanstead Abbotts, Ware, Hertford and the surrounding areas.
1. Why the American midterm elections matter
The US midterm elections take place halfway through a President's four-year term. Unlike presidential elections, they determine the balance of power in Congress rather than who occupies the White House.
Following the November 2026 results, the Democrats now control both chambers of Congress. This creates a different political environment for President Trump, potentially making it more difficult for his administration to pass new legislation without support from opposition lawmakers.
One area attracting particular attention is international trade.
Over recent years, tariffs have been a prominent feature of American economic policy. Tariffs are taxes placed on imported goods and can increase costs for businesses, manufacturers and consumers.
A change in political direction could eventually lead to different trade negotiations, reduced trade restrictions or closer relationships with international trading partners.
However, there is no guarantee that tariffs will be removed or reduced. The President retains significant executive powers over trade, and the election results alone do not change existing tariffs.
For the UK, any future improvement in international trade relations could potentially be positive for businesses and economic confidence. The wider effects would depend on the policies actually introduced.
2. The connection between American politics and UK mortgage rates
This is perhaps the most important connection for anyone looking to buy a home.
You might assume that UK mortgage rates are determined entirely by the Bank of England. While its decisions are extremely important, the reality is more complicated.
Mortgage lenders also take account of financial market interest rates, expectations about future borrowing costs and the risks associated with lending.
The Bank of England has explained that a two-year fixed mortgage rate is influenced by the relevant two-year market interest rate, alongside additional costs and considerations for the lender.
So where does America come into this?
The United States has one of the world's largest financial markets. Its government bonds, known as US Treasury bonds, are closely watched by investors around the world.
When American economic or political decisions cause investors to become concerned about inflation, government borrowing or financial stability, the prices and yields of these bonds can change.
Those movements can spread into other financial markets, including the UK.
For example, if investors demand higher returns from government bonds, UK borrowing costs can also come under pressure. This can influence the wider financial environment in which mortgage lenders set their rates.
It does not mean a change in American policy automatically makes UK mortgages cheaper or more expensive. However, it demonstrates why international developments can influence the cost of borrowing here.
For someone purchasing a home in Hertfordshire, even a relatively small change in mortgage rates can make a noticeable difference to monthly repayments and affordability.
3. We've already seen American decisions affect UK financial markets
This is not simply a theoretical connection. We have already seen it happen.
In April 2025, President Trump announced significant increases in US import tariffs, creating considerable uncertainty across international financial markets.
Investors reacted, with sharp movements in share prices, government bonds and currency markets.
The Bank of England subsequently reported that increases in US Treasury yields had spilled over into government bond yields in the UK, Japan and several other advanced economies.
In other words, financial market movements that began in response to American trade announcements were also being felt here in Britain.
This is a particularly useful example of how quickly international economic uncertainty can spread.
It also demonstrates why changes in American trade policy are monitored by financial institutions well beyond the United States.
4. Could changes in trade tariffs reduce the cost of building homes?
Another area worth considering is the construction industry.
Building a home involves a considerable number of materials, components and products, many of which are sourced through international supply chains.
Changes to trade tariffs, shipping costs, exchange rates and international relationships can all influence what businesses pay for materials.
If international trade becomes more predictable and businesses face fewer trade barriers, there could be benefits for manufacturers and suppliers.
However, the direct relationship between American tariffs and British building costs is not quite as straightforward as it might seem.
Government trade statistics show that the UK's largest construction material import markets in 2025 included China, Germany, the Netherlands, Italy and Turkey. The United States, meanwhile, was one of the UK's largest export markets for construction materials.
This means that changes to US trade policy may have a more direct effect on some British manufacturers and exporters than on the cost of materials imported by UK housebuilders.
There could still be indirect effects through global supply chains, business confidence and currency movements.
For Hertfordshire, where new housing developments and infrastructure projects remain important to the area's future, the wider cost of construction is something worth keeping an eye on.
5. Political events have influenced the UK housing market before
American developments aren't the only examples of political and economic decisions affecting the British property market. Looking back at previous events helps demonstrate just how interconnected these issues can be.
The 2008 global financial crisis
One of the clearest examples began in the United States with problems in its sub-prime mortgage market.
Some American lenders had issued mortgages to borrowers who were considered higher risk. As increasing numbers of borrowers struggled to repay their loans, financial institutions began to suffer substantial losses.
The crisis spread through international banking and financial markets, eventually contributing to the credit crunch in Britain.
UK banks became more cautious about lending, mortgage availability reduced and buyers found it increasingly difficult to obtain finance.
The result was a significant downturn in the UK housing market. Property transactions fell, house prices declined and developers began scaling back building projects.
A crisis that originated in the American mortgage market had serious consequences for British homeowners and buyers.
The September 2022 mini-budget
Closer to home, the September 2022 mini-budget demonstrated how domestic political decisions can affect the cost of borrowing.
Following the Government's fiscal announcements, UK government bond yields increased sharply, placing considerable pressure on financial markets.
Mortgage lenders reacted to the changing financial conditions, with many withdrawing products or repricing their deals.
The Bank of England's December 2022 Financial Stability Report recorded that the average advertised rate for a new two-year fixed mortgage at 75% loan-to-value had risen to around 6%, compared with below 2% in recent years.
There were several contributing factors, including rising inflation and expectations of further interest rate increases. The mini-budget was not the sole cause, but it demonstrated how quickly political uncertainty can influence mortgage pricing.
Both examples show that the property market doesn't operate in isolation. It is closely connected to the wider financial and economic environment.
6. What does this mean for homeowners and buyers in Hertfordshire?
So, bringing everything back to our local area, should people buying or selling in Stanstead Abbotts, Ware, Hertford and the surrounding villages be concerned about what is happening in America?
Not necessarily, but it is worth understanding the bigger picture.
The latest available Office for National Statistics figures provide an interesting snapshot of the East Hertfordshire property market.
In August 2026, the average house price in East Hertfordshire was £456,000, representing a 1.9% increase over the previous year.
For first-time buyers, the average purchase price was £357,000.
The rental market also showed annual growth, with average monthly rents reaching £1,550 in September 2026, an increase of 4.8% compared with the previous year.
These figures demonstrate that the local market has its own characteristics and is influenced by a range of factors beyond international politics.
For anyone considering a move, some of the most important things to watch remain:
Mortgage affordability: Changes in borrowing costs can influence how much buyers are able to spend.
Buyer confidence: Economic uncertainty can make people more cautious about committing to a purchase.
Employment and household income: A stable local economy helps people feel more confident about moving home.
Housing supply: The number and type of properties available locally will continue to influence prices.
Construction and development: Building costs and the availability of new homes can affect the balance between supply and demand.
American politics may influence some of these factors indirectly, but local housing conditions, UK economic policy and the Bank of England remain much closer influences on our property market.
7. Should you wait for international politics to settle before moving?
It can be tempting to delay a property decision when there is uncertainty in the news.
However, waiting for international markets or political developments to settle completely is unlikely to be a practical strategy. There will always be another election, economic announcement or global event that could influence financial markets.
For buyers, the more useful approach is to understand what you can afford, explore available mortgage options and find a property that suits your circumstances.
For sellers, understanding local demand, competing properties and realistic achievable values is far more useful than trying to predict the next movement in international markets.
Every buyer and seller has different priorities, and the right time to move ultimately depends on individual circumstances.
Looking Beyond the Headlines: Your Local Property Experts
The recent American midterm elections are an interesting reminder of just how connected the global economy has become.
A decision made in Washington can influence international financial markets, which can affect UK borrowing costs and ultimately feed into the mortgage market here in Hertfordshire.
However, it is important to keep things in perspective. American political developments do not determine local house prices, and a change in the political balance of Congress does not automatically mean lower tariffs, cheaper mortgages or a stronger housing market.
What matters most is understanding how the wider economic picture connects with what is happening locally.
