Strategists at the brokerage cited continued challenges from the COVID-19 pandemic and the Russia-Ukraine war -- which skyrocketed inflation to decades-high levels and triggered aggressive policy tightening -- as reasons behind the outlook.

"We see global performance as likely (being) plagued by 'rolling' country-level recessions through the year ahead," said Citi strategists, led by Nathan Sheets.

The Wall-Street investment bank also expects growth in the U.S. economy to more than halve to 0.7% in 2023 from its earlier projection of 1.9% growth in 2022.

It expects year-on-year U.S. inflation at 4.8% next year, with the U.S. Federal Reserve's terminal rate seen between 5.25% and 5.5%.

Among other geographies, Citi sees the UK and euro area to fall into recession by the end of this year, as both economies face the heat of energy constraints on supply and demand front, along with tighter monetary and fiscal policies.

For 2023, Citi projects UK and euro area to contract 1.5% and 0.4%, respectively.

In China, the brokerage expects the government to soften its zero-COVID policy, which is seen driving a 5.6% growth in gross domestic product next year.

Emerging markets, meanwhile, are seen growing 3.7%, with India's 5.7% growth -- slower than this year's 6.7% prediction -- seen leading among major economies.
