Quora Answer: How is Money Laundered through Cash Businesses?

The following is my answer to a Quora question: “How is money laundered through cash businesses?”

Money is laundered through cash businesses because there is less of a paper trail to follow.  Ledgers can be manipulated in many ways, from underdeclared sales to overdeclared expenses, with the difference moved elsewhere.

Take a fruit business.  Fruit is bought in bulk, sold in individual packages.  The consignment’s weight does not reveal the number of individual pieces sold, leaving a wide margin to manipulate.  Run it cash-only, keep two sets of books, one real, one for declaration, and the gap absorbs earnings from other illegal activity, giving dirty money a legitimate-looking home.  Gangs apply the same method to seafood businesses, food stalls, and restaurants.  Bars, lounges, and nightspots work especially well, since cash tips provide a further layer to disguise illicit funds moving through the till.

Casinos remain the most effective cash business for this purpose.  A casino can absorb millions in a single night, and chips provide a cross-jurisdiction transfer mechanism, cashed out at a sister casino under the same group, an internal ledger transfer that bypasses ordinary compliance checks.

How Singapore Law Catches This

The Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act 1992 governs money laundering prosecution in Singapore.  Under Sections 50 and 51, anyone who knowingly, or with reasonable grounds to believe, helps another person retain or use criminal proceeds commits an offence, carrying a fine up to S$500,000 and up to ten years’ imprisonment for an individual, or a fine up to S$1 million or twice the value of the laundered benefit for a company, whichever is higher.  Sections 53 and 54 separately criminalise concealing, converting, or transferring property known to represent criminal proceeds, precisely the mechanism a two-books cash business runs on.

The 2024 Anti-Money Laundering and Other Matters Act made prosecution easier.  Previously, prosecutors had to prove laundered money in Singapore traced directly to specific criminal conduct, often requiring evidence from foreign jurisdictions that never materialised.  The amendment removed that requirement.  Prosecutors now only need to show the accused knew, or had reasonable grounds to believe, they were managing criminal proceeds, regardless of whether the underlying crime can be pinned down.

Casinos Face Tighter Rules Now

The Casino Control Act 2006 already imposed customer due diligence and transaction monitoring obligations on casino operators.  The 2024 amendments tightened this further, aligning Singapore’s framework with Financial Action Task Force standards.  Casino operators must now consider proliferation financing risk alongside money laundering and terrorism financing risk during customer due diligence, and the threshold triggering mandatory due diligence checks on cash transactions or deposits was lowered to S$4,000, effective 14^th November 2024.  The chip-transfer method described above, moving value between casinos under the same operator, sits inside this tightened due diligence regime.

Singapore’s largest money laundering case to date involved over S$3 billion in seized assets, following raids across affluent neighbourhoods in August 2023.  Ten foreign nationals, mostly Chinese nationals holding passports from Cambodia, Turkey, Cyprus, and Vanuatu, were convicted and sentenced to between 13 and 17 months in prison, with 98.6 per cent of their assets, S$1.85 billion, surrendered to the state.  Su Wen Qiang, the first to plead guilty, forfeited over S$5.9 million after earning proceeds from an illegal remote gambling operation based in the Philippines, serving clients in China.  Su Bao Lin had S$777,220.50 in cash and a Toyota Alphard seized, having earned 4 million USDT operating illegal gambling websites.  The Monetary Authority of Singapore separately penalised nine banks and financial institutions a combined S$29.1 million for compliance failures connected to the case, including Credit Suisse, UOB, UBS, Citibank, Julius Baer, and LGT Bank.

This case ran primarily through banking, property, and cryptocurrency channels rather than cash retail businesses specifically.  It remains the clearest illustration of how seriously Singapore now pursues laundering once detected, and the same CDSA provisions used to convict these ten individuals apply with equal force to a fruit stall running two sets of books or a nightclub layering cash tips into its declared revenue.
