Singapore’s best private bank chief investment office 2026: Bank of Singapore

Bank of Singapore presents one of the most well-rounded chief investment office (CIO) platforms in Singapore, shaped by a thoughtful blend of global expertise, disciplined investment methodology and accessible client engagement.

Its CIO global advisory council – comprising about 10 leaders from economics, geopolitics, policy and investment – offers perspectives that are not always offered by its peers. This is reinforced by a consistent flow of publications, from Supertrends to timely event‑driven updates, which position the CIO office as a reliable source of insight rather than solely a portfolio‑focused function.

The bank’s investment framework further supports this credibility. Its SAA 2.0 strategic asset allocation (SAA) approach uses advanced optimisation and scenario stress‑testing, distilling a universe of well over a trillion potential portfolios into a refined set of robust options. Process transparency is a clear priority, with a building‑block SAA layout and practical tactical asset allocation case studies across regional equities, commodities and FX demonstrating how views are translated into portfolio decisions.

The bank also offers large‑scale events, multilingual AI‑supported delivery and a wide range of digital channels, including webinars, podcasts and localised platforms, which help to ensure that clients can engage with CIO guidance in a format that works best for them.
