IMF downgrades UK and US growth forecasts - BBC News
Lower activity in the first quarter of 2017 suggests both will underperform the global economy.
The IMF's forecast for UK growth in 2018 is unchanged

The UK and US economies will expand more slowly in 2017 than previously predicted, according to the International Monetary Fund (IMF).

It said "weaker-than-expected activity" in the first three months of the year meant the UK would grow by 1.7%, compared with an earlier 2% forecast.

The IMF also revised down its US growth forecast from 2.3% to 2.1%.

However, its overall global economic predictions - of 3.5% growth in 2017 and 3.6% in 2018 - remain unchanged.

The UK growth forecast for 2018 remains unchanged at 1.5%, but US growth for next year is now predicted to come in at 2.1%, instead of the 2.5% previously forecast.

In its latest World Economic Outlook, the IMF said the "pick-up in global growth" that it had anticipated in its previous survey in April remained "on track".

But it added that while the global growth projection was unchanged that masked "somewhat different contributions at the country level".

The IMF's chief economist, Maurice Obstfeld, told the BBC that the organisation was watching closely the impact of Brexit on the UK's future economic health.

"We have long predicted that Brexit would have some negative long-term effects, but in the case of this year's forecast [downgrade] we are basing it purely on the observation of data for the first part of this year which has been weaker than expected.

"Our projections for long-term British growth are actually based on a pretty optimistic assessment of how the negotiations are likely to turn out, so if things are worse than that it will turn out to be correspondingly worse for the British economy."

A UK Treasury spokesperson said the IMF forecast underlined why the government's plans to increase productivity and get "the very best deal with the EU" after Brexit were "vitally important".

"Employment is at a record high and the deficit is down by three quarters, showing that the fundamentals of our economy are strong," they added.

Economists warned that IMF forecasts were not always right.

"The IMF, a multi-lateral institution, takes a step back and looks at a broad range of activities across the world, but they do sometimes get things wrong and we wouldn't want to put too much emphasis on what's been released today," said Lucy O'Carroll, chief economist of Aberdeen Asset Management.

The downgrade in the UK's forecast reflects the weak start to the year.

The economy grew by 0.2% in the first three months. That is all we get by way of explanation from the IMF.

It is a short report - just seven pages - and it updates the IMF's assessment for the whole world economy so there isn't much space to spell it out.

The IMF is well known, some would say notorious, for warning before last year's referendum of the adverse economic consequences of leaving the European Union.

Do the agency's economists think that the downgrade reflects evidence suggesting that they were right? The report doesn't say. The IMF's chief economist told the BBC that the revision was based purely on the weakness at the start of the year.

We will get a bit of hard evidence on how justified the downgrade was or was not later this week, when the Office for National Statistics publishes its first estimate of economic growth in the second quarter of the year.

The IMF said that the main factor behind its downward revision for US growth in 2018 was "the assumption that fiscal policy will be less expansionary than previously assumed, given the uncertainty about the timing and nature of US fiscal policy changes".

"Market expectations of fiscal stimulus have also receded."

President Donald Trump's administration had been widely expected to pursue policies including tax cuts and infrastructure investment to try to boost the US economy.

However, the chances of the administration being able to push through these policies now appears less likely.

The eurozone is seeing "stronger momentum", the IMF said

The IMF's outlook for several eurozone economies was brighter than initially thought, with countries including France, Germany, Italy and Spain seeing growth forecasts revised up.

The biggest eurozone revisions were for the Spanish and Italian economies. Spain is now forecast to grow 3.1% this year, up from the previous prediction of 2.6%. Italy's 2017 growth forecast has risen from 0.8% to 1.3%.

The euro area as a whole is expected to grow by 1.9% this year, up from 1.7%.

The IMF said first-quarter growth in many of those countries was better than expected, and that there was evidence of "stronger momentum in domestic demand than previously anticipated".

China's growth projections have also been revised up, reflecting, the Fund says, "a strong first quarter of 2017 and expectations of continued fiscal support".

Its 2017 forecast has risen from 6.6% to 6.7%, while growth in 2018 is now expected to be 6.4% instead of 6.2%.

The IMF hailed China's "policy easing and supply-side reforms", including efforts to reduce excess capacity in the industrial sector.
