His arrival in June 2019 follows Ninety One's demerger from Investec Asset Management in March. Investec AM launched in South Africa back in 1991 is rooted in emerging market principles, hence the name of the London and Johannesburg-listed spin off.

Siow joins the business from BlueBay Asset Management, where he specialised in emerging markets and fixed income investment. He held similar responsibilities at Alchemy Special Situations and Citigroup Salomon Smith Barney.

His relocation to Hong Kong bolsters Ninety One’s fixed income team in Asia, reflecting the region's strong interest in the asset class and Asia’s growing importance as an investment destination for global investors, the group said. The independent global asset firm manages roughly £104 billion in assets.
