GLOBAL ECONOMY - Asia's factory output weakens on global slowdown, China COVID curbs

Further U.S. interest rate hikes are also expected to force most Asian central banks to prevent sharp capital outflows by tightening their own monetary policies, even if it means cooling already soft economies, analysts say.

Manufacturing activity shrank in South Korea, Taiwan and Malaysia in October, and expanded at the slowest pace in 21 months in Japan, highlighting the pain from slowing Chinese demand and stubbornly high import costs.

China's Caixin/S&P Global manufacturing purchasing managers' index (PMI) stood at 49.2 in October, up from 48.1 in September but remaining below the 50-point mark that separates growth from contraction.

The private sector survey was in line with an official PMI survey released on Monday that showed China's factory activity unexpectedly fell in October.

"Asia is extremely reliant on China. Its zero-COVID policy continues to disrupt supply chains and keep Chinese travelers from returning to Asian tourist destinations. It's also hurting the region's exports," said Toru Nishihama, chief economist at Dai-ichi Life Research Institute in Tokyo.

"Another big risk is the pace of U.S. rate increases. If the Federal Reserve continues to hike rates steadily, that could ignite capital outflows from Asia and hurt exports."

Japan's au Jibun Bank Japan Manufacturing PMI fell to 50.7 in October from September's 50.8 final, marking the weakest growth since January last year.

Highlighting how the pain from soaring material costs and supply constraints outweighed the boost from a weak yen, auto giant Toyota Motor Corp7203.T on Tuesday posted a 25% drop in quarterly profit and cut its annual output target.

South Korea's factory activity shrank for a fourth straight month in October as orders for exports fell for an eighth month, the PMI showed.

That followed data that showed South Korea's exports fell the most in 26 months with shipments to China, its largest market, extending declines.

"Given the country's open economy and its subsequent reliance on exports, the looming global downturn certainly poses a downside risk for future growth," Laura Denman, an economist at S&P Global Market Intelligence, said on South Korea's PMI.

Taiwan's PMI slid to 41.5 in October from 42.2 in September, while that for Malaysia fell to 48.7 from 49.1, surveys showed.

Factory activity in Indonesia expanded at a slower pace in October with the PMI standing at 51.8, down from 53.7 in September.

India was an outlier with factory activity expanding at a stronger pace in October as demand remained solid.

The International Monetary Fund cut Asia's economic forecasts as global monetary tightening, rising inflation blamed on the war in Ukraine, and China's sharp slowdown dampened the region's recovery prospects.
