US stocks as digital tokens: opportunities and security risks loom

The prospect of trading American stocks as digital tokens is gaining traction among financial technology innovators, potentially streamlining settlement processes and broadening market access. However, regulators and security analysts have flagged substantial risks accompanying such a shift in how equities are bought and sold.

Tokenisation of stocks would involve converting share ownership into blockchain-based digital assets, theoretically enabling faster transactions and reduced intermediaries. Proponents argue this could democratise access to US equities for investors across Southeast Asia and beyond.

But cybersecurity breaches pose an immediate concern. The US$6.3 billion hack at cryptocurrency exchange Binance in 2023 illustrated vulnerabilities in digital asset platforms, raising questions about whether traditional stock markets would face similar threats if migrated to decentralised systems.

Regulators are particularly concerned about three areas. Money laundering risks could increase if tokenised stocks enable easier cross-border transfers with limited oversight. Insider trading detection becomes more complex on decentralised networks where transactions are harder to trace. Additionally, the custody and insurance frameworks protecting traditional stock holdings remain unclear for tokenised versions.

Financial authorities in Singapore and across the region are monitoring developments closely as they weigh innovation benefits against systemic risks to capital markets stability.
