In response to Singapore’s largest money-laundering scandal involving over SGD3bn (USD2.22bn) laundered through 16 financial institutions, banks such as Citigroup Inc and DBS Group Holdings Ltd are intensifying scrutiny on their wealthy clients. These banks are adopting stricter customer vetting processes and providing additional training to private bankers to detect criminal tactics in fund sourcing. The Monetary Authority of Singapore (MAS) has completed on-site inspections and anticipates issuing fines and other penalties to those most implicated. Meanwhile, Singapore’s government has initiated a review to strengthen anti-money-laundering defences across various sectors. The case, which involved significant sums in accounts and resulted in several convictions, has spurred banks to evolve their anti-money laundering protocols to preempt criminal adaptations.
