May 20 (Reuters) - Foreign selling in Asian equities has accelerated so far in May as investors turn cautious over the impact of war-driven inflation and higher borrowing costs on corporate margins across the region.
Foreign investors have so far sold a net $24.75 billion of regional equities this month, with a record $17.27 billion of shares divested in the last week, LSEG data covering exchanges in South Korea, Taiwan, Thailand, India, Indonesia, Vietnam and the Philippines showed.
The 30-year U.S.
Treasury yield climbed to its highest level since 2007 this week, adding pressure on Asian equities as higher long-term borrowing costs weighed on valuations, particularly in growth-heavy markets.
"Higher yields could increase pressure on equities as tighter financial conditions could weigh on valuations, particularly in growth sectors," said Paolo Broccardo, CEO at BankPro, in a note.
South Korean stocks faced a record $13.14 billion worth of foreign outflows in the last week. Last week, investors also divested $2.88 billion of local shares in Taiwan, $1.35 billion in India and $184 million in Indonesia.
"Mainland China H-share, Hong Kong, Korea and Taiwan equities are traditionally most sensitive to an increase in yields," said Herald van der Linde, head of equity strategy for Asia Pacific at HSBC.
"30% of Asian funds’ exposure is to a handful of stocks in Korea and Taiwan. Any de-risking may cause more volatility in these markets," HSBC's Linde said.
Indonesian and Thai stocks have, however, still attracted $511 million and $215 million of foreign inflows, so far this month.
