PARIS: Global economic growth will pick up only moderately over the next year as the full effects of central bank rate hikes are felt, the OECD said on Wednesday, the latest to flag the impact of monetary tightening.

The world economy is set to grow 2.7% this year, the Organisation for Economic Cooperation and Development (OECD) said, up from its previous forecast of 2.6% in March.

Though boosted by the lifting of China’s zero-COVID policy, that would be the lowest annual rate since the 2008-2009 global financial crisis with the exception of the pandemic-hit year of 2020, the Paris-based organisation said.

Growth would then accelerate only slightly next year to 2.9% - unchanged from March’s forecast - as rate hikes by major central banks over the last year increasingly drag on private investment, starting with housing markets.

On Tuesday, the World Bank also cited the growing impact of rate hikes as it raised its forecast for world growth this year to 2.1% but for 2024 cut it back to 2.4% from a previous 2.7% forecast. A sharp fall in May for Chinese exports released on Wednesday also pointed to weakening global demand.

The OECD forecast that inflation in the Group of 20 major economies would fall from 7.8% last year to 6.1% this year and 4.7% in 2024 - still well above many central banks’ targets despite the interest rate hikes.

“A substantial risk is that inflation proves to be more persistent and in response interest rates need to be higher for longer,” OECD chief economist Clare Lombardelli told a news conference.

OECD head Mathias Cormann chimed in saying that the risk of major central banks doing too little or too much was currently “evenly balanced”.

US Federal Reserve officials have flagged a possible pause in interest rate hikes while the European Central Bank has indicated that further increases are likely in the coming months. In the OECD’s outlook, the US Federal Reserve’s main interest rate was seen peaking soon at 5.25-5.5%, with “modest” rate cuts in the second half of 2024.
