Surging food and energy prices drove inflation to 5.4% in the 12 months to December, up from 5.1% the month before, in a blow to struggling families.
The International Monetary Fund expressed concern that a Russian invasion of Ukraine could see energy prices go even higher and stay there for longer.
Its first deputy managing director, Gita Gopinath, backed the idea of help with spiralling energy bills in the UK.
That intervention could be helpful to the Treasury, which is currently deciding what type of help could be given to mitigate a £50-a-month rise in bills.
Some MPs want the government to delay its announced rise in National Insurance, especially after lower-than-expected public borrowing figures.
The Treasury is believed to be looking instead at focusing support on those most in need.
Omicron woes
On Tuesday, the IMF sharply downgraded its forecasts for the two biggest global economies – the US and China – citing high energy prices and new Covid curbs among its reasons.
Overall, the IMF now expects global growth to go from 5.9% in 2021 to 4.4% in 2022, half a percentage point lower for this year than in its last prediction in October 2021.
“The global economy enters 2022 in a weaker position than previously expected,” said the IMF report.
As the new Omicron Covid-19 variant spread, countries had reimposed restrictions, it added.
“Rising energy prices and supply disruptions have resulted in higher and more broad-based inflation than anticipated, notably in the US and many emerging market and developing economies.
“And the ongoing retrenchment of China’s real estate sector and slower-than-expected recovery of private consumption have limited growth prospects.”
The IMF predicted that the higher levels of inflation currently seen in the global economy would go on for longer than it anticipated in its last forecast, persisting for most of 2022.
It said supply chain disruptions, energy price volatility and localised wage pressures meant that “uncertainty around inflation and policy paths” was high.
Big revisions
US economic growth for this year was downgraded by the IMF from 5.2% to 4% after it removed the effects of President Joe Biden’s Build Back Better fiscal policy package from its calculations.
China’s forecast for 2022 was cut from 5.6% to 4.8%.
“In China, disruption in the housing sector has served as a prelude to a broader slowdown,” the IMF report said.
“With a strict zero-Covid strategy leading to recurrent mobility restrictions and deteriorating prospects for construction sector employment, private consumption is likely to be lower than anticipated.”
The IMF said the cut in expectations for global growth also reflected revisions among some other large emerging markets.
In particular, the two biggest Latin American economies, Brazil and Mexico, suffered the largest growth downgrades.
Brazil, where far-right President Jair Bolsonaro is seeking re-election later this year, is now expected to grow by just 0.3% in 2022, down from the previous forecast of 1.5%.
Mexico also saw a downgrade of 1.2 percentage points and is now predicted to see growth of 2.8%.
