Foreigners turned net buyers of Asian stocks in April, bolstered by rising expectations the US Federal Reserve will pause its aggressive tightening cycle, and by other factors such as a weaker dollar and strong first-quarter company earnings.

Data from stock exchanges in India, Indonesia, the Philippines, South Korea, Taiwan, Thailand, and Vietnam showed foreigners purchased a net $872 million of equities in April - the biggest monthly buying since January.

Bets on more tightening by the Fed have waned recently as the failure of three US regional banks stoked concerns of a recession, while higher interest rates have increased borrowing costs for businesses and consumers.

The Fed raised interest rates by a quarter of a percentage point on Wednesday as expected and signalled it may pause further increases, giving officials time to assess the fallout from recent bank failures and inflation trends.

Chetan Seth, an equity strategist at Nomura, said any weakness in Asian stocks due to US recession concerns will be an opportunity for investors to raise their exposure to the region due to supportive factors such as China's recovery, an expected bottoming out of the tech sector downturn, and a strong 2024 earnings recovery.

According to Refinitiv data, Asian companies have beaten net income expectations by 3 per cent in the March quarter.

Indian equities received a net $1.42 billion worth of foreign inflows, the biggest since November 2022, thanks to a rally in local shares.

Indian shares were the best performers in the region last month, with Nifty 50 marching 4.1 per cent in its biggest monthly rise since November 2022.

Foreigners also purchased Indonesian, South Korean and Philippine equities of $830 million, $616 million and $34 million, respectively.

Meanwhile, Taiwan saw $1.73 billion worth of net selling, and Thai equities saw outflows of $231 million.

Yeap Jun Rong, a strategist at IG, said the US dollar staying near a one-year low was also supportive of EM Asia equities.

The greenback fell 0.94 per cent in a second straight month of decline against a basket of major world currencies in April, as expectations of further Fed rate hikes eased.
