Singapore private bank onboarding: MAS targets one-month median

Singapore’s central bank told private banks on May 25 to cut the time it takes to open an account for wealthy clients. The Monetary Authority of Singapore wants the median down to one month. Right now, complex cases take six weeks or more.

The Monetary Authority of Singapore published a circular telling financial institutions to run “risk-proportionate” source-of-wealth checks. Speaking at the UBS Asian Investment Conference Singapore Wealth Edition, MAS managing director Chia Der Jiun said banks have layered on unnecessary steps as they tightened anti-money laundering procedures, and the new guidance strips those out.

“It provides further guidance for applying the principles of materiality and relevance, so that financial institutions can avoid unnecessary and excessive steps in the process and be more targeted,” Chia said.

“The guidelines are expected to cut the median time needed to open an account to within one month, from the current six weeks or longer for more complex cases.”

The compliance backdrop

A S$3bn (US$2.2bn) money-laundering scandal in 2023 forced Singapore to rethink how it polices wealth management. The case involved a network of foreign nationals moving illicit funds through the banking system. The response was a clampdown: banks added due-diligence layers for new clients, especially those from jurisdictions with opaque corporate structures. Account openings ran well past six weeks for complex files.

The new circular leaves the underlying AML rules in place. What it changes is how banks apply them — calibrating the intensity of source-of-wealth checks to each client’s risk profile instead of running every applicant through the same exhaustive procedure. The specific frictions MAS wants gone are redundant document requests and sequential compliance reviews that add weeks without catching more illicit money.

Private banks in Singapore have roughly doubled their compliance headcount since the 2023 scandal. The cost of that expansion, plus the longer onboarding cycles, has squeezed the profitability of wealth-management businesses that need a steady flow of new assets. Every extra week of onboarding is a week a prospective client can spend talking to a rival booking centre.

The wealth-hub calculus

Competition for global private capital has heated up in the three years since the laundering cases broke. Cross-border wealth flows into Asia picked up as family offices and ultra-high-net-worth individuals moved assets out of mainland China, Europe and the Middle East. Hong Kong introduced a family-office tax concession in 2024. Dubai pitched itself as a low-friction alternative. In that environment, how fast a bank can open an account has become a competitive differentiator — not just a back-office metric.

Singapore housed roughly 1,400 single-family offices as of end-2025, up from 700 in 2021, according to MAS data. Keeping that growth going means the regulatory environment has to look rigorous without looking obstructive. The central bank is trying to redraw that line.

MAS said it is working with the private banking industry group to develop case studies and training for relationship managers and compliance professionals, with rollout expected in the coming months. The goal is to give front-office and compliance teams a shared, practical framework for what proportionate due diligence looks like under the new guidance.

The circular does not set hard deadlines for individual banks. Institutions keep discretion over their internal processes. But the one-month median target gives the regulator a clear yardstick. Banks that do not move toward it over the next several quarters will stand out in a market where onboarding speed now matters almost as much as safety in deciding where to book assets.
