America has slapped a 10% tariff on most UK goods going into the US, and economists are already cutting their forecasts for the British economy. Oxford Economics dropped its UK growth prediction for 2026 to just below 1%, down from 1.5% before the tariffs came in. That might sound like something that only matters to suits in Westminster, but it feeds through to your mortgage, your investments, and your weekly costs. So it’s worth understanding what’s actually happening.
What Are the Tariffs and Why Should You Care
A tariff is basically a tax on imported goods. When the US puts a 10% tariff on British exports, it makes our products more expensive to buy over there. UK businesses that sell to America either absorb the cost or lose customers. Either way, they end up making less, which means less hiring, tighter budgets, and more caution across the board.
The UK shifts a serious amount of goods to the US. Scotland’s whisky industry alone sent nearly £1 billion worth of product to America in 2024, according to the House of Commons Library. Add cars, machinery, pharmaceuticals. These are big employers. When they start hurting, it works its way through the whole economy eventually.
The Growth Problem
Slower growth makes businesses pull back. Orders get cancelled, projects get shelved, people stop spending. One firm in Lancashire told the British Chambers of Commerce that clients had cancelled a significant project because of tariff uncertainty. That’s real money gone, not a theoretical graph going in the wrong direction.
What It Means for Your Mortgage
This is probably where most people will feel it most directly, and not necessarily in a bad way.
Because the tariffs are expected to slow growth, markets are now betting more heavily that the Bank of England will cut interest rates to prop things up. AJ Bell put the odds at around 50% that the base rate drops to 3.5% or lower by the end of the year. If you’re on a variable rate or your fixed deal is ending soon, that’s worth watching.
The complication is inflation. The Bank of England’s February Monetary Policy Report was pretty honest about this, saying that while tariffs will likely slow UK activity, what they’ll do to inflation is less clear. If prices stay stubbornly high, the Bank’s hands are tied on cuts.
The Inflation Risk
NIESR has put out a forecast suggesting a full tariff escalation could push UK inflation up by 3 to 4 percentage points over two years. That’s not small. More expensive goods, higher energy costs, prices creeping up in places you don’t expect.
If your mortgage fix is ending in the next 12 months, don’t just roll onto whatever your lender offers automatically. Shop around. A 0.3% difference on a £200,000 mortgage is around £600 a year. That’s worth an hour of your time.
What It Means for Your Investments
Markets didn’t take the tariff news well. If you’ve got money in a Stocks and Shares ISA or a pension, you’ve probably noticed your balance looking a bit worse than it did a few months ago.
If you’re putting money in regularly, say £200 a month into an index fund, a market dip is actually not the disaster it feels like. Your money buys more units when prices are lower. When things recover, those extra units are worth more. This is called pound cost averaging, and it’s one of the better arguments for investing consistently rather than trying to time when to go in.
If you’ve put in a lump sum and you’re watching it drop, the temptation is to pull it out and stop the bleeding. Don’t. Every major shock in market history has eventually recovered. Selling when prices are down just turns a paper loss into a real one.
Should You Be Doing Anything Differently
Honestly, not much. The basics still apply. Get your emergency fund sorted before you invest anything, three to six months of living costs in a cash savings account. That’s your cushion against whatever happens next.
If you haven’t used this year’s ISA allowance yet, it’s a reasonable time to think about it. Markets being down means you’re potentially getting in cheaper than you would have six months ago.
FAQ
Will Trump’s tariffs push up prices in the UK? They might, but it’s not a straight line. NIESR’s forecast puts potential inflation at 3 to 4 percentage points higher if things escalate fully. The Bank of England has been careful not to commit either way. Some goods from the US could get pricier, but the bigger impact is likely through slower growth and weaker business confidence rather than an immediate spike at the supermarket.
Could interest rates actually come down because of this? That’s what the market is betting on right now, with roughly 50/50 odds on the base rate hitting 3.5% or lower by year end. Slower growth gives the Bank of England reason to cut. The wildcard is inflation. If prices stay up, cuts get delayed.
Should I pause my investments until this blows over? No. Nobody knows when it blows over, and sitting in cash waiting for the right moment usually means missing the recovery. Keep investing regularly, don’t panic sell, and let it ride.
Tariff situations move fast and the picture in six months usually looks different to the one today. Stay calm, keep your finances in order, and don’t make long term decisions based on short term noise.
