Britain’s economy will be among the hardest hit by the global trade war and inflation is set to climb, the International Monetary Fund (IMF) has warned – as it slashed its UK growth forecast by a third.
In a sobering set of projections, the Washington-based organisation said it was grappling with “extremely high levels of policy uncertainty” – and the global economy would slow even if countries manage to negotiate a permanent reduction in tariffs from the US.
Echoing earlier warnings about the risks to the global financial system, the IMF said stock markets could fall even more sharply than they did in the aftermath of Donald Trump‘s “Liberation Day” tariffs announcement, when US and UK indices recorded some of their largest one-day falls since the pandemic.
It comes as Chancellor Rachel Reeves prepares to meet her US counterpart Scott Bessent at the IMF’s spring gathering in Washington this week.
She is hoping to negotiate a reduction to the 10% baseline tariff the US president has applied to all UK goods. Steel, aluminium and car exports face an additional 25% tariff.
As long as the world’s two largest economies are at war with each other, there will be considerable spillovers. The US and China account for 43% of the global economy.
If demand in either nation slows, that has ripple effects across the world. Tariff or no tariff, exporters to those markets will be hurt.
If China redirects its goods elsewhere, that could hurt domestic industries – jobs could be at stake.
US and Chinese investors might hit pause on global projects and stock market devaluations could hurt consumer confidence. Things could unravel quickly.
Against that backdrop, it is difficult to say with any certainty what would happen to the UK but, even if we find a way to sweet talk our way out of tariffs, the dark clouds of the global economy are moving in every direction.
Britain is an open and highly trade-sensitive economy (we have a trade-to-GDP ratio of around 65%) and global spillovers will rain on us.
Then there are the spillovers from the financial markets. The IMF warned that rising government borrowing costs were weighing on economic growth.
While rising UK bond yields are, in part, a reflection of investor unease over the UK’s growth and inflation outlook, they also reflect anxiety over the US trajectory.
It’s worth bearing all of this in mind if Chancellor Rachel Reeves emerges from her trip to Washington with a deal.
The Treasury would no doubt celebrate the achievement. After all, a reduction in tariffs could make a big difference to some industries, especially our car manufacturers who are currently grappling with a 25% levy on goods to their largest export market. However, it would not solve our problems.
In fact, it would barely make a difference to our overall GDP. Back in 2020, the government estimated that a free trade deal with the US would boost the UK economy by just 0.16% over the next 15 years.
And overall GDP does matter. The chancellor desperately needs economic growth to support the country’s ailing public finances (when the economy grows, so do government tax receipts).
She will know better than most that the prize the US has to offer is comparatively small, so she should weigh up the costs of any deal carefully.
The IMF presented a range of forecasts in its latest World Economic Outlook. Its main case looked at the period up to 4 April, after Mr Trump announced sweeping tariffs on countries across the world, ratcheting up US protectionism to its highest level in a century.
If the president were to revert to this policy framework, global growth would fall from 3.3% last year to 2.8% this year, before recovering to 3% in 2026.
In January, the IMF was predicting a rate of 3.3% for both years.
Nearly all countries were hit with downgrades, with the US expected to grow by just 1.8% this year, a downgrade of 0.9 percentage points.
Mexico was downgraded by 1.7 percentage points, while China and Canada are forecast to slow by 0.6 percentage points and Japan by 0.5 percentage points.
The UK economy is expected to grow by just 1.1% this year, down 0.5 percentage points from the 1.6% the IMF was predicting in January. Growth picks up to 1.4% next year, still 0.1 percentage points lower than the January forecast.

Will tariffs hit UK growth?
Along with recent tariff announcements, the IMF blamed the UK’s poor performance on a rise in government borrowing costs, which has in part been triggered by growing unease among investors over the fate of the US economy.
When borrowing costs rise, the chancellor has to rein in public spending or raise taxes to meet her fiscal rules. That can weigh on economic growth.

Trump: Tariffs are making US ‘rich’
It also pointed to problems in the domestic economy, mainly “weaker private consumption amid higher inflation as a result of regulated prices and energy costs”.
In a blow to the chancellor, the IMF warned that the UK would experience one of the largest upticks in inflation because of utility bill increases that took effect in April.
It upgraded its inflation forecast by 0.7 percentage points to 3.1% for 2025, taking it even higher above the Bank of England’s 2% target and deepening the dilemma for central bankers who are also grappling with weak growth.
Meanwhile, inflation in the US is likely to jump one percentage point higher than previously forecast to 3% in 2025 on the back of higher tariffs.
The IMF forecast period ended on 4 April. That was before the US president paused his reciprocal tariffs on countries across the world while ratcheting up levies on China.
In a worrying sign for finance ministers across the world, as they attempt to negotiate a deal with the US administration, the IMF said the global economy would slow just the same if Mr Trump were to make his temporary pause on reciprocal tariffs permanent.
That is because higher tariffs between the US and China, which together account for 43% of the global economy, would have spillover effects on the rest of the world that offset the benefits to individual countries.
“The gains from lower effective tariff rates for those countries that were previously subject to higher tariffs would now be offset by poorer growth outcomes in China and the United States – due to the escalating tariff rates – that would propagate through global supply chains,” the IMF said.
In response, Chancellor Rachel Reeves said:
“This forecast shows that the UK is still the fastest-growing European G7 country. The IMF have recognised that this government is delivering reform which will drive up long-term growth in the UK, through our plan for change.
“The report also clearly shows that the world has changed, which is why I will be in Washington this week defending British interests and making the case for free and fair trade.”
Two men have been charged with the murder of paedophile Lostprophets singer Ian Watkins, who was killed in prison.

Steve Witkoff, the US special envoy to the Middle East, has claimed the UK played a “vital role” in helping negotiate the Gaza peace deal, smoothing over a potential diplomatic row between London and Washington.
Witkoff took to X on Monday, ahead of meeting President Donald Trump in Israel, to praise the UK.
“I would like to acknowledge the vital role of the United Kingdom in assisting and coordinating efforts that have led us to this historic day in Israel,” Witkoff wrote.
“In particular, I want to recognise the incredible input and tireless efforts of National Security Advisor Jonathan Powell.”
His comments came 24 hours after education secretary Bridget Phillipson was branded “delusional” by Mike Huckabee, the US ambassador to Israel, for claiming that Sir Keir Starmer’s presence at a signing ceremony for today’s ceasefire deal in Egypt “demonstrates the key role that we [Britain] have played”.
Phillipson added: “We have played a key role behind the scenes in shaping this.
“It’s right that we do so because it’s in all of our interest, including our own national interest, that we move to a lasting peace in the region.
“These are complex matters of diplomacy that we are involved in. But we do welcome and recognise the critical role that the American government played in moving us to this point.”
Her comments prompted Mr Huckabee to repost the Sky News clip on social media, claiming: “I assure you she’s delusional.”
He added: “She can thank Donald Trump anytime just to set the record straight.”

Mr Huckabee was part of the negotiating team for the peace deal, with Mr Trump calling the former Arkansas governor “AMAZING” as he said he “worked so hard, and did so much, to bring about peace in the Middle East”.
In August, Mr Huckabee said the UK and other European nations that said they would declare a Palestinian state were “having the counterproductive effect that they probably think that they want”.

Israel’s deputy foreign affairs minister, Sharren Haskell backed Huckabee, telling Sky News the UK played “the opposite” of a key role in the peace deal after recognising the Palestinian state.
“The message that the UK government has sent Hamas was the message that: the longer they continue this war, they will be rewarded.
“I mean, you must understand that when a terrorist organisation is thanking you. You are on the wrong side of history.”
It is understood the prime minister has underlined Mr Trump’s key role in securing this deal throughout the process. Publicly, he praised Mr Trump twice in his press conference in India on Thursday.

Final preparations for hostages in Israeli hospital
Ms Phillipson stood by the September decision to declare a Palestinian state, saying it was “the right thing to do”.
Husam Zomlot, the Palestinian ambassador to the UK, told Sky News it was a “moment of leadership” for the UK to declare a Palestinian state, and a “responsibility to begin to correct a century of the gravest historic injustices committed against our people”.
He added: “That moment three weeks ago, when the UK did recognise, is a moment when we can say that the wheels of history are turning in a different direction.”
No plans for British troops on the ground
The education secretary also told Sky News the government has “no plans” to put British troops into Israel or Gaza as part of a stabilisation force after the ceasefire.
The US military will help establish a multinational force in Israel, known as a civil-military coordination centre, which is likely to include troops from Egypt, Qatar, Turkey and the UAE.

On Friday, US officials said up to 200 US troops already based in the Middle East will be moved to Israel to help monitor the ceasefire in Gaza.
The day before, President Trump announced Israel and Hamas had “signed off on the first phase” of a peace plan he unveiled last week.

Aid trucks have been gathering in Egypt to cross into Gaza after months of warnings by aid groups of famine in parts of the territory.
In Israel, the remaining hostages are due to be returned from Gaza by Hamas on Monday under the first phase of the peace plan. Twenty are believed to still be alive, 26 have been declared dead, while the fate of two is unknown.
The ceasefire agreement has been made two years after Hamas stormed Israel on 7 October 2023, killing 1,200 people and taking 251 hostages.
Israel’s military offensive has killed more than 67,000 Palestinians in Gaza, according to the Hamas-run health ministry, which the UN deems reliable.
Sir Keir Starmer will join world leaders at a historic summit in Egypt today – to witness the signing of the Gaza peace plan to end two years of conflict, bloodshed and suffering that has cost tens of thousands of lives and turned Gaza into a wasteland.
Travelling over to Egypt, flanked by his national security adviser Jonathan Powell, the prime minister told me it was a “massive moment” and one that is genuinely historic.
In the flurry of the following 48 hours, Sir Keir and another 20 or so leaders were invited to Egypt to bear witness to the signing of this deal, with many of them deserving some credit for the effort they made to bring this deal around – not least the leaders of Qatar, Egypt and Turkey, who pressed Hamas to sign up to this deal.
Today, the remaining 20 living hostages are finally set to be released, along with the bodies of another 28 who were either killed or died in captivity, and aid is due to flow back into a starving Gaza.
Some 1,200 Israelis were killed on 7 October 2023, with another 250 taken hostage. In the subsequent war, most of Gaza’s two million population has been displaced. More than 67,000 Gazans have been killed, according to Palestinian health officials.
Then, the signing ceremony is due to take place this afternoon in Sharm el Sheikh. It will be a momentous moment after a long and bloody war.

Humanitarian aid rolls into Gaza
The immediate focus for the UK and other nations will be to get aid into Gaza, with the UK committing £20m for water, sanitation and hygiene services for Gazans.
But the focus for the UK and other European allies is what happens after the hostages are released and Israel withdraws its troops.
What happens next is a much bigger and more complicated task: rebuilding Gaza; turning it into a terrorist-free zone; governing Gaza – the current plan is for a temporary apolitical committee; creating an international stabilisation force and all the tensions that could bring about – which troops each side would allow in; a commitment for Israel not to occupy or annex Gaza, even as Netanyahu makes plain his opposition to that plan.
The scale of the challenge is matched by the scale of devastation caused by this brutal war.
The prime minister will set out his ambition for the UK to play a leading role in the next phase of the peace plan.

Back home, the UK is hosting a three-day conference on Gaza’s recovery and reconstruction.
Last week, France hosted European diplomats and key figures from Middle Eastern countries, Egypt, Jordan, Saudi Arabia and Qatar – and later this week, the German chancellor is hoping to organise a conference on the reconstruction of Gaza with the Egyptians.
But in reality, European leaders know the key to phase two remains the key to phase one, and that’s Donald Trump.
As one UK figure put it to me over the weekend: “There is lots of praise, rightly, for the US president, who got this over the line, but the big challenge for us post-war is implementing the plan. Clearly, Arab partners are concerned the US will lose focus.”

The prime minister knows this and has made a point, at every point, to praise Mr Trump.
His cabinet minister Bridget Phillipson learned that diplomatic lesson the hard way yesterday when she was publicly lambasted by the US ambassador to Israel Mike Huckabee for suggesting to my colleague Trevor Phillips that the UK “had played a key role behind the scenes” and failed to mention Mr Trump by name.
“I assure you she is delusional,” tweeted Governor Huckabee. “She can thank @realDonaldTrump anytime just to set the record straight”.
Today, leaders will rightly be praising Mr Trump for securing the breakthrough to stop the fighting and get the remaining hostages home.

But this is only the beginning of a very long journey ahead to push through the rest of the 19-point plan and stop the region from falling back into conflict.
Britain has, I am told, been playing a role behind the scenes. The PM’s national security adviser Mr Powell was in Egypt last week and has been in daily touch with his US counterpart Steve Witkoff, according to government sources. Next week the King of Jordan will come to the UK.
Part of the UK’s task will be to get more involved, with the government and European partners keen to get further European representation on Trump’s temporary governance committee for Gaza, which Tony Blair (who was not recommended or endorsed by the UK) is on and Mr Trump will chair.
The committee will include other heads of states and members, including qualified Palestinians and international experts.
As for the former prime minister’s involvement, there hasn’t been an overt ringing endorsement from the UK government.
It’s helpful to have Mr Blair at the table because he can communicate back to the current government, but equally, as one diplomatic source put it to me: “While a lot of people in the Middle East acknowledge his experience, expertise and contact book, they don’t like him and we need – sooner rather than later – other names included that Gulf partners can get behind.”
Today it will be the US, Egypt, Qatar and Turkey that sign off on the peace plan they directly negotiated, as other Middle Eastern and European leaders, who have flown into Sharm el Sheikh to bear witness, look on.
But in the coming days and weeks, there will need to be a big international effort, led by Mr Trump, not just to secure the peace, but to keep it.
