Just over two weeks before John Healey delivers his first budget as chancellor, the International Monetary Fund has sent a clear message: don't take your foot off the pedal. In its latest World Economic Outlook, the IMF nudged up its forecast for UK GDP growth in 2026 to 1.3%, a modest upgrade that nonetheless sets Britain apart from many of its G7 peers. But the fund's top economist, Silvana Tenreyro, paired that praise with a warning: the improvement is fragile, and the repair job on the public finances is far from finished.
Tenreyro, the IMF's economic counsellor, said the UK "stands out" among advanced economies for having a credible plan to narrow its deficit. That may sound like faint praise in normal times, but these are not normal times. With global borrowing costs still elevated, geopolitical tensions simmering, and a string of elections across the developed world producing fragmented politics, any country that can point to a fiscal anchor is a rarity. The message to Healey was blunt: stay the course.
Why the IMF Is Watching Healey So Closely
Healey, who took over the Treasury in a reshuffle earlier this year, has spent his first months in office signalling continuity rather than revolution. His budget on 30 October is expected to thread a narrow needle: enough consolidation to keep bond markets onside, enough investment to satisfy a restive backbench, and enough realism to avoid the kind of Truss-style meltdown that still haunts Westminster. The IMF's intervention, unusual in its timing and specificity, effectively endorses that approach while gently warning against any deviation.
The fund's economists are not known for sentimentality. When they say a country "stands out", it is usually because they have run the numbers and found something that distinguishes it from the pack. In the UK's case, that something is a multi-year plan to bring the deficit down, even if the pace is slower than some fiscal hawks would like. The alternative, Tenreyro implied, is the kind of stop-start policymaking that has characterised British fiscal policy for much of the past decade.
The Growth Upgrade in Context
An upgrade from 1.2% to 1.3% may not sound like much, and in absolute terms it isn't. But in the world of forecasts, direction matters as much as magnitude. The IMF's revision reflects slightly stronger-than-expected consumer spending, a rebound in business investment, and a labour market that has proven more resilient than many economists predicted. It also reflects the absence of a major negative shock, which in recent years has been the exception rather than the rule.
Still, the fund was careful to temper its optimism. It noted that growth is likely to "edge down" next year, a projection that should give Healey pause. The reasons are familiar: the lagged effect of higher interest rates, weaker global demand, and the fading of one-off factors that flattered this year's numbers. In other words, the upgrade is real but not a reason for complacency.
The Fiscal Tightrope Healey Must Walk
Healey's budget will be judged on three fronts: credibility with markets, fairness to households, and consistency with the government's broader growth agenda. The IMF's advice touches all three. On credibility, it wants to see a clear path to lower borrowing. On fairness, it has repeatedly urged governments to protect the most vulnerable during consolidation. On growth, it has emphasised the importance of public investment in areas like infrastructure, skills, and green technology.
The chancellor's room for manoeuvre is limited. Debt as a share of GDP remains near historic highs, and the interest bill alone consumes a substantial chunk of tax revenue. Any significant giveaways would need to be offset by tax rises or cuts elsewhere, neither of which is politically painless. That is why the IMF's phrase "stay the course" is more than a platitude. It is a recognition that the alternative, a sudden lurch in policy, would be far more damaging.
What 'Stay the Course' Actually Means
In practical terms, staying the course means resisting the temptation to loosen fiscal policy simply because growth has ticked up. It means sticking to the spending reviews already announced, even when they are unpopular. It means not promising tax cuts that cannot be funded. And it means communicating clearly why the repair job matters, not just to bond markets but to ordinary households who will ultimately bear the cost of failure.
Tenreyro's comments also carry a subtle warning about the global environment. The IMF has repeatedly flagged that the world economy "could soon test the limits of resilience", a phrase that captures the combination of high debt, low productivity growth, and rising fragmentation. For a small, open economy like the UK, that external backdrop matters enormously. No amount of domestic fiscal discipline can fully insulate Britain from a global downturn, but it can ensure the country enters one with more fiscal space than it would otherwise have.
The Political Economy of Fiscal Repair
There is a reason fiscal repair is so difficult in democracies: the costs are immediate and visible, while the benefits are diffuse and delayed. Healey will face pressure from his own party to spend more on public services, from the opposition to cut taxes, and from markets to do neither. The IMF's intervention gives him cover to resist the loudest demands, but it also raises expectations. If he deviates, the fund's next report will not be so kind.
It is worth remembering that the IMF is not always popular in British politics. Its warnings during the Brexit debate were dismissed by some as scaremongering, and its advice during the 2010s austerity era was criticised for being too hawkish. But its current message is notably balanced: it praises the plan while warning against complacency. That is not a political stance; it is an economic one.
What to Watch in the Budget
Three things will signal whether Healey is genuinely staying the course. First, the overall borrowing envelope: if it is higher than expected, markets will ask why. Second, the composition of spending: investment that boosts long-term growth is more defensible than day-to-day spending that does not. Third, the tone: a budget that acknowledges trade-offs is more credible than one that promises something for everyone.
The IMF's forecast upgrade is a small vote of confidence, but it is not a blank cheque. The fund's economists will be watching the budget as closely as anyone. If Healey delivers a credible plan, he will have earned the right to say he is repairing the finances. If he doesn't, the next World Economic Outlook may make for uncomfortable reading.
Frequently Asked Questions
What did the IMF say about John Healey's fiscal plans?
The IMF's top economist, Silvana Tenreyro, urged Healey to "stay the course" and continue repairing the UK's public finances. She noted that the UK stands out among G7 countries for having a plan to narrow its deficit, but warned against complacency given likely slower growth ahead.
Why did the IMF upgrade its UK growth forecast for 2026?
The upgrade to 1.3% reflects stronger-than-expected consumer spending, a modest rebound in business investment, and a resilient labour market. It also assumes no major negative shocks. However, the fund expects growth to edge down the following year as higher interest rates and weaker global demand weigh on activity.
How could the IMF's advice affect the upcoming UK budget?
Healey's budget on 30 October will be scrutinised for signs of fiscal discipline. The IMF's endorsement gives him cover to resist pressure for unfunded tax cuts or spending increases, but it also raises expectations. If the budget is seen as loosening the purse strings too much, market confidence could suffer.
What does 'stay the course' mean for ordinary households?
In practice, it means the government will prioritise reducing borrowing over short-term giveaways. That could mean slower increases in public spending or higher taxes in some areas. The IMF argues that this is necessary to keep borrowing costs down, which ultimately benefits households through lower mortgage and loan rates.
