Malaysia's economy grew at its fastest pace in a year last quarter, thanks to a strong rebound in private consumption and buoyant exports, but a global economic slowdown poses a significant risk to the outlook, a Reuters poll found.

The Aug. 3-9 poll of 18 economists predicted southeast Asia's third-largest economy expanded 6.7% in the April-June quarter compared with the same period a year earlier.

That would be the fastest growth since the same quarter last year.

Forecasts for annual gross domestic product (GDP) growth, due to be released on Aug. 12, ranged from 5.2% to 9.2%, higher than the 5.0% increase in the preceding quarter.

"Private consumption was likely the main growth driver ... Furthermore, a sharp jump of 30% YoY (year-on-year) in Q2 export growth would have contributed to the faster Q2 GDP print," said Vincent Loo of KAF Investment Bank.

Export growth was 22% in the first quarter, Loo said.

"We expect GDP growth to accelerate further in Q3, mainly due to base effects (nationwide lockdown in Q3 2021) before normalising in Q4 and into next year on the back of slowing global trade, rising inflationary pressure and tighter monetary conditions."

"While overall export growth performed well ... its open economy is exposed to growing global economic headwinds and slowdown driven by U.S. Fed tightening and European energy insecurity from the Russia-Ukraine war, even as China tries to recover from the pandemic lockdown-induced weakness," said Chua Han Teng of DBS.

A separate Reuters poll showed Malaysia's economic growth for this year would be 6.5%, higher than Bank Negara Malaysia's (BNM) forecast of 5.3%-6.3%, though then slow to 4.6% in 2023.

But Malaysia's central bank was expected to follow its global peers and continue on its rate hiking path to tame rising inflation.

Last month, BNM raised its benchmark interest rate for a second straight meeting by 25 basis points to 2.25%.
